Today, undoubtedly, the most accessible, effective and economical option heating of residential buildings is gas water heating. For apartment buildings, in the private sector, in places where there is a centralized gas supply, gas becomes the main type of fuel. However, when the heating season is in full swing, situations often arise when the allotted limits for gas consumption are quickly exhausted. What to do in such cases? How to save gas in a private home, thereby reducing heating costs? The only way out in such situations is to have auxiliary heat sources on hand.
What are the best heating alternatives to gas? How much something costs and what effect is achieved in this case is a problem with several unknowns that we have to solve.
There is no gas - we are considering all possible heating methods
Increased financial costs for heating a residential building during the cold period, excessive consumption of blue fuel, a frequent and familiar situation for many owners of private houses. Let's try to find the best way out of this situation together. The main condition that in this case relevant - not inferior in its technological parameters to gas water heating that is familiar to us.
Having assessed all technical capabilities various options heating, let’s take a closer look at each of them.
The most proven and old way heating a residential building - . In rural areas, in the private sector, you can still find houses where there is a traditional stove not just as an element ethnic decor, but as an important component of home life. Most common are combination stoves, which act as a heat source and serve for cooking. Having a stove in the house will save gas, especially if there is an abundance of firewood and its quantity is not limited.
If such a stove is available in the house, the issue with an alternative option for heating the house has been resolved. Despite the existing disadvantages that are typical for stove heating. When the house is warm at relatively low costs, few people pay attention to the soot and soot present in the room. The only aspect that remains in attention is the fire safety of stove heating.
Important! The oven needs constant cleaning. Optimal mode operation depends on the condition of the chimney. Good traction allows you to avoid the accumulation of combustion products hazardous to health, and access to fresh air guarantees an acceptable level of CO 2 in the room.
Another equally convenient option, if there is no gas, is to use liquid fuel heating systems. The main type of fuel in this case is diesel fuel. Less common are boiler models that run on rapeseed oil or kerosene. Heating a private house in this case will be effective, taking into account high efficiency liquid fuel boilers. Heating residential premises with diesel fuel is used quite rarely. The reason for this is the difficulty of storing large volumes of diesel fuel and the high fire hazard of such heating systems. And who would like the constant smell of diesel fuel in the house, eternal dirt and soot?
Use solid fuel in cases where gas needs to be saved, this is the optimal option. In our country, neither firewood, nor coal, nor peat are unusual, so using them as fuel is convenient, rational and efficient, from an economic point of view. We have already talked about the home stove, but the option remains to install solid fuel or universal boilers. It's up to you to decide which is more profitable or coal. It all depends on the availability of each type of fuel in a particular region.
Modern technologies have stepped forward, providing consumers with wide choice models of equipment that, through the combustion of solid fuel, have high heat transfer. Solid fuel pyrolysis boilers They have a fairly high efficiency, about 80%, are equipped with automation, and do not require constant human presence and frequent loading of fuel. Solid fuel is still the most cheap way heating Existing disadvantages It’s up to you to evaluate such heating options, especially when there is a question of quickly and effectively replacing missing gas.
Combined, multi-fuel boilers, offered today by many firms and companies, have a high cost. Due to objective reasons, such a technique has not yet found its niche in consumer market, taking into account the financial capabilities of the population.
Important! Before you take up the calculator and do calculations without gas, you need to eliminate the confusion between volumes measured in cubic meters. meters and fuel mass, measured in kilograms. It is better to measure all types of fuel, except electricity, in kilograms, since the calorific value of the fuel is related to weight.
It is appropriate here to conduct an unbiased analysis of the efficiency of using different types of fuel. The table below will give you a clear idea of what type of fuel is most efficient today, and the cheaper it is to heat a house.
These tables allow you to carry out simple calculations yourself by substituting the current cost of fuel.
The cost of thermal energy obtained by using each type of fuel is calculated as follows:
We roughly divide the cost of fuel in your region by the specific calorific value of the fuel. We divide the data from the second column by the parameters indicated in the third column. In the fifth column we enter the data from the calculation:
- to heat a private house of 100 m2 during the heating season, 5 kW/h will be required;
- 24, number of hours in a day;
- take into account the duration heating season- 180 days (6 months).
As a result, we get: 5 x 24 x 180 = 21600 kW/h.
As can be seen from the table, the data for all types of fuel used in our homes are the same. This indicates approximately the same efficiency of the proposed heating options. The only amendment is possible when it comes to different sizes of the building. The household intensity of use of heating devices and the thermal efficiency of a private home play a significant role. The calculated value of 5 kW/h is typical for a well-insulated modern materials buildings. The duration of the heating season may also vary depending on the climate of the region.
Let us multiply the cost of 1 kW/h of thermal energy in each individual case by the total number of kilowatt hours, and obtain the cost of each type of fuel. We divide the obtained figures by the theoretical value of the efficiency of equipment for burning each type of fuel, we obtain the actual efficiency parameters and the answer - the more profitable it is to heat buildings without gas.
Electricity is a worthy replacement for gas due to its absence
Economical, efficient heating a private house or dacha should be more focused on preserving the familiar living conditions. The level of comfort determines the choice alternative way heating, besides today technologies provide ample opportunities for maneuver. The availability of electricity will allow you to achieve gas savings in the cold season. No wonder many owners country houses And country cottages, due to the lack of technical capabilities for connecting to the gas main, they give preference electrical systems heating.
Compared to other heating devices, electric heating devices have almost 100% efficiency. An electric boiler is easy to maintain and inexpensive. In this case, there is no need for exhaust hood and chimney equipment. Electricity remains by far the most affordable alternative to gas heating when considering efficiency and ease of maintenance.
In addition to installation in the house electric boiler for water heating systems, convectors are actively used for heating small residential buildings, heat guns And infrared emitters. The installation of heated floors in a private home is becoming a fashionable phenomenon today. The technology is quite new, however, it has already proven its effectiveness. The variety of heat sources offered gives you the opportunity to make a choice as to how best to heat your home.
Note: In the event that a heated floor is your main source of heating residential premises, the power of the equipment should be 150-180 W per m2 of living space. Warm floors must have an area of at least 70-80% of the total area of the building itself. Otherwise, the expected heating effect will be negligible.
When heating a private home using other methods, you can achieve even higher economic indicators. Without gas, economical and uninterruptible source You can obtain thermal energy in your area using a heat pump. The operating principle of the equipment is based on the difference in temperature, deep in the soil and on the surface. By using heat pump, which really costs a lot of money, you can provide yourself with an almost eternal source of heat in a country house. The effectiveness of this system is confirmed by simple calculations. Indicator successful work heat pump is the heat conversion coefficient (COR).
For example. When a heat pump consumes 1 kW of electricity necessary to ensure the operation of the entire system (Htn), the heat conversion coefficient (COP) is 3.0, which means:
Rtn x COP = 3 kW Rp energy output. Savings and efficiency this method heating is more than obvious.
There is no clear answer to the question: is it more profitable to heat? private house gas or other fuels does not exist. In each individual case, the presence of a variety of factors plays a role, not least of which are the economic and technical capabilities of the consumer.
Instead of gas for heating, you can use almost any fuel. Another thing is how fully you can heat own house in cold weather, create for yourself comfortable conditions residence. When faced with such a situation, the choice is yours. How to save money and make your heating costs optimal depends on you, on your attitude to the very fact of saving energy and technical capabilities.
Efficient home heating system.
The costs of maintaining a home for private homeowners are already quite high. That is why the question is so popular, what is the cheaper way to heat a house, the answer to which will save your budget.
Why is it profitable to heat your home yourself?
In terms of heating, the owners country houses luckier than city residents. After all, cottage owners can turn on the heating in their home at any time of the year, since they do not depend on a centralized heating system. Other advantages and benefits include:
- the ability to turn on the heating in the house at those moments when it is necessary.
- the ability to adjust the temperature to the desired level.
- the ability to independently select heating options (solid fuel, electricity, gas).
However, here the main question arises - how to heat a house economically and what heating method is considered the most profitable? This is what we have to figure out.
What is the best way to heat a house - how to decide?
To understand how to heat a house inexpensively, you need to answer several important questions:
- Will you live in the house full time or only for a few seasons a year?
- Is the quality of heating or the financial side of the issue more important to you?
- How much can you spend on equipping all the necessary systems?
Important: no one will give a universal answer to the question of how to heat a house economically. It all depends on various factors: prices for energy resources and fuel, costs of purchasing and installing equipment and a number of other factors. However, once you familiarize yourself with the heating options, making a choice will be much easier.
Stove heating and its features
The oven is considered the most in a profitable way heating.
When considering options for how to profitably heat a private home, one cannot fail to mention stove heating, which has not lost its relevance over many years. Installing a stove in a house is a difficult job, so it should only be trusted to professional specialists. However correct installation oven is a guarantee of its long-term operation.
The stove is heated with wood or coal, and therefore you should stock up on “fuel” in advance so that it is enough for long time. Dry logs of hard woods, such as beech and oak, provide a lot of heat. Damp pine also burns normally, but it will provide little heat in the house.
The main thing to remember is that the stove requires maintenance. So, you cannot do without cleaning the chimney and constantly removing ash.
To keep the rooms always warm, you need to constantly add firewood, while observing all necessary measures security. Otherwise, a fire cannot be avoided.
To reduce the risk of fire hazards, it is better to line the floor near the stove with iron, but it is not recommended to line it with parquet boards or linoleum. If so flooring If a spark occurs, a fire may occur.
Heating with a fireplace: is it profitable?
Fireplace heating is similar to stove heating, but has some differences: it will not be possible to heat a house effectively in this way. A fireplace is most often installed only for beauty, since its heat is enough to warm up the room where it is installed.
We can’t talk about savings here either. If you are wondering what is more profitable to heat your house, we can safely say that it is not with the help of a fireplace. Despite the fact that the fireplace runs on wood or coal, it consumes a lot of “fuel” but produces almost no heat. Thus, it should be installed only in conjunction with some other type of heating equipment - so to speak, for the soul.
Water heating system
A water heating system will allow you to heat your house profitably.
Today they are increasingly saying that a fairly popular method is to heat a house efficiently using a water heating system. However, here we should immediately make a reservation - the heating bill itself may be small, but you will have to spend money on installing equipment, laying pipes, installing batteries, a tank and a pump. In addition, the cost of heating directly depends on the equipment.
To do this, you need to understand how the system works. So, there must be a boiler with the function of heating water, which then goes through pipes and enters. After some time, the water cools down and goes back to the boiler, where it is heated again. This system works in a vicious circle. In some cases, you cannot do without a special pump when supplying liquid on a forced basis.
Many people are interested in how it is more economical to heat a house with a water heating system, because it is known that it can work on various energy sources. That is why equipment is usually divided into:
- electric boilers;
- gas equipment;
- solid fuel boilers.
When answering the question of how to heat a house economically, it is worth focusing on gas and solid fuel boilers, since the cost of “fuel” in this case is quite acceptable. Electric boilers can be quite expensive due to the cost of electricity.
Using heaters for heating
Modern heaters are very efficient and safe method heating rooms. Especially if people live in the house not all the time, but several seasons a year. Most profitable option consider the use of oil radiators, which store heat for a long time and consume a small amount of energy.
Thus, to determine which type of heating is best for you, you must first explore all the available options, weighing their advantages and disadvantages, economic costs for installation and operation. Don’t forget to choose a heating option based on the time you spend in the country house. After all, if you live in a dacha only in summer time year, a fireplace and stove will be enough, but if you live there in winter, without quality system heating is indispensable.
Nowadays, many owners of private country houses or summer cottages are increasingly having to look for an alternative to gas as the main type of fuel to heat their homes. The reasons are different: for some natural gas becomes too expensive, some have the opportunity to use other energy sources, while others simply cannot access mains gas due to its complete absence nearby. Then the question arises: what kind of economical heating at home without gas and what fuel is better to use then?
Alternative energy sources
A clear answer to this question does not exist, since each individual case has its own nuances. For example, on your plot of land there are many old big trees, which just beg to be put into the firebox of a wood-burning boiler.
Option two: in exchange for certain services, the customer is ready to supply you with diesel fuel or coal for a long time. It is clear that in such situations you will be inclined to these types of energy carriers and not pay attention to others. In the long term, this will be a mistake, since such sources will sooner or later dry up and you will have to look for other ways to heat a country house or buy the same fuel, but at a generally accepted cost.
We will try to develop some kind of universal method for determining the optimal energy carrier for heating a home, which will suit everyone special case. First, let’s make a reservation that the methodology will help you determine for yourself the cheapest heating without gas; we do not take it into account.
Just as we do not take into account various high-tech and exotic species heating, inaccessible to ordinary citizens. This includes heat pumps, solar panels, wind turbines and various types machine and vegetable oils. Then how to heat the house if there is no gas and the above sources? We still have at our disposal: 
- ordinary firewood;
- Euro firewood;
- pellets;
- coal;
- diesel fuel;
- liquefied gas in cylinders;
- electricity.
For each of these energy sources, you should calculate the costs for the entire cold period, then it will be clear how cheaper it is to heat a house.
Important! Before starting calculations, it is imperative to harmonize the units of measurement of the amount of fuel, that is, to prevent confusion between volume (m3) and mass (kg). It is recommended that all types of energy carriers, except electricity, be converted to units of mass - kilograms.
Calculating heating costs
To find out what is the most economical heating for a country house, it is recommended for clarity to draw up a simple plate like this:
In this table, the second column is filled in based on the cost of each type of fuel in your region, or your individual price is entered in it. The third column has already been filled in for ease of calculation. The cost of 1 kW of thermal energy can be easily determined by dividing the price of 1 kg of fuel (column 2) by its specific calorific value (column 3).
The fifth column is filled in based on the fact that the average consumed thermal power in a private house with an area of 100 m2 per season is 5 kW/h, and the duration of the heating season is 180 days (5 x 24 x 180 = 21,600 kW/h).
It is clear that the house designs are all different and the area will be different, as well as the length of the season in your region, so you will need to make appropriate adjustments. By multiplying the data in columns 4 and 5, we determine the estimated costs for the season.
However, these values do not take into account the operating efficiency of the equipment, the values of which are given below. Dividing the estimated costs by the efficiency value, in the last column we get a direct answer to the question - what is cheaper to heat a house besides gas.
For those homeowners in whose homes are already installed gas boilers, you can add another line below for comparison, filling it with data on natural gas, based on actual fuel consumption and its price.
It would seem that now everything has fallen into place and you can calmly make a choice in favor of one energy source or another for economical heating. But this approach is one-sided, because there is also such a thing as convenience and complexity in maintaining and operating the heating system of a private home.
Choosing an energy carrier based on ease of use
Comfortable operation of boiler equipment that supplies heat to water heating is an important factor, since any unnecessary hassle and inconvenience is your time and money. That is total costs indirectly increase in accordance with how much effort is put into maintaining the operation of the system. In some cases, economical heating systems no longer seem so economical after the first season, and sometimes you want to pay extra money just not to deal with such problems.
Unlike financial indicators, ease of use is a constant value for each type of fuel, so it can be found out immediately, which will help you make a choice. We will evaluate convenience according to the following criteria:
- the difficulty of repairing or maintaining the boiler installation;
- necessity and convenience of storage;
- comfort in daily use (need for loading fuel, etc.).
To find out which energy carrier will provide comfortable and economical heating private house, we will draw up a second table, where for each of the criteria we will give all types of fuel ratings according to a five-point system, after which we will summarize.
Service
Requires no maintenance electric boilers, except for sometimes opening the cover and brushing off dust or cleaning the contacts, for which they receive the highest rating. Some actions are required if heating country house liquefied gas. Once every 2 years it is recommended to check and, if necessary, clean the igniter and burner, which is why propane is a solid four. Pellet boilers receive 3 points because they require cleaning the combustion chamber several times a year and the chimney once.
Accordingly, wood and coal units need to be cleaned frequently as they become dirty. The worst situation in this regard is with diesel fuel, since its quality often leaves much to be desired, which is why the frequency of maintenance is unpredictable.
Warehousing
It is clear that electricity does not require storage space, while liquefied gas and diesel fuel may require some space. But when economical heating of a private house with wood is organized, then a lot of space for a warehouse will be required. The same goes for pellets, since they require dry room or special silo. As for coal, it produces a lot of waste, dust and dirt, so this is the lowest rating.
Ease of use
And here it is economical electric heating turned out to be excellent, since it does not require any intervention during operation. Pellets and liquefied gas must be replenished periodically, 1-2 times a week, or even less often. You should pay attention a little more often diesel fuel, more for supervising the work than for the purpose of adding fuel.
Well, what traditionally causes the most trouble is independent heating in a private house using coal and wood, here loadings into the combustion chamber are needed from 1 to 3 times a day.
The last column summarizes the results according to which heating is the most comfortable and convenient country house in winter using electricity. If this result is considered in conjunction with financial costs, then electricity may not be the worst option.
Conclusion
An integrated approach to the issue shows that the most economical heating systems for a summer house and country house may turn out to be the most troublesome during operation. Therefore, you should not rush and carefully weigh and calculate everything, or even better, install an electric boiler in combination with any other.
How to at least warm it up small room or heat/cook food in the absence of such an achievement of civilization as electricity? The review contains advice and instructions from people who have already encountered such a pressing problem.
In a situation where the room is cold, the heating is not working and the electric heater either cannot be turned on, or not in any way - there is no light, for example - anyone can find themselves. And Lugansk residents are already familiar with the ban on using electric heaters due to the danger of overloading power lines, which could lead to a complete blackout of the city from electricity, as the Lugansk City Council warns about almost daily.
And if in the summer, in the absence of light, the only question is how to prepare food, then with the onset of cold weather, the problem of heating the room becomes no less acute.
But, as they say, the need for invention is cunning. And Lugansk residents are not the only ones who are faced with the problem of heating a room in the absence of basic amenities of civilization. Below we have collected popular and tried-and-true methods for heating a small (!) room, heating food and improvised heating pads from scrap materials.
1. Candle heater
The candle flame shines quite nicely, but trying to warm up with it seems crazy. Meanwhile, just as a light source, a candle is an extremely wasteful device. But as a room heater it can be useful. Under a number of conditions.
Californian inventor Doyle Doss and his company DOSS Products offer the original Kandle Heeter system, that is, the “Candle Heater”.
This strange-looking candlestick, its creator claims, can be indispensable during a power outage. Its height is about 23 and its width is about 18 centimeters.
And from it appearance The inverted pot above the candle attracts attention. In this pot (and it's in " past life» flower pot and was) and the main highlight of the system is hidden.
This pot is not simple, but composite. It is made from three pots different diameters, nested one inside the other and connected by a long metal bolt, on which a whole bunch of washers and nuts are strung (fortunately, pots usually already have holes in the bottom).
An ordinary candle, burning in a room, produces, as it seems, very little heat. But the point here is that its hot “exhaust” simply goes up and quickly evaporates with the ventilation.
Meanwhile, the energy reserve in the candle is not so small. Moreover, with the hot flow of combustion products, most of its energy content leaves, and only a smaller part is converted into light.
The labyrinth cap above the flame collects energy and carefully stores it, heating up quite strongly (the central rod is especially hot). And then this heat is slowly transferred to the air by the entire surface of the ceramic radiator.
The pots also help trap soot from the fire, which helps keep the ceiling clean.
The inventor emphasizes that one such device will in no way save you in the winter when the heating and electricity are turned off, but, on the other hand, it is better than nothing at all.
By the way, clay pots are certainly not bad, but they have poor thermal conductivity and it is better to replace them with a similar metal structure, for example from cans different sizes or old Soviet cans for bulk products, who else keeps these as a memory :))
2. Mini tea light warmer
The author purchased a tent heater powered by tea candles. Several of these heaters save fishermen in tents from freezing. Which means a few candles in tin cans with holes for air intake, suitable for a small room or office :)
3. Heater + camping stove for heating food from cans - alcohol lamp
The design is known abroad as an alcohol stove, or in Russian - an alcohol lamp. The Swedish army has even adopted it.
Alcohol is used because it does not smoke when burned. This means the dishes remain clean and no soot or smoke floats in the air. The design is as simple as 3 kopecks and can be repeated in a few minutes from any available materials. For example, a beer can, coffee can, or condensed milk can be used as a donor for the stove.
More specifically: you need a small iron container with an iron lid, or you will have to cover it with something.
So: we take a jar, a ruler, a strip of checkered leaves and a marker or any drawing or scratching object.
1. Mark a stripe on the can, moving one third from the top. The easiest way to do this is by spinning the jar while holding the marker in one position.
2. We wrap a strip of paper around the edge of the mark and fasten it with a piece of tape or glue.
3. We begin to drill, pierce with an awl or cut holes with a knife along the marked strip. In this case, I made a series of holes with a diameter of 0.8 mm through 10 mm and through 5 mm - which option is better for you - decide for yourself. You can see how they burn below. A small hole diameter for proper combustion is better than a large one, but you can make 3-5 holes a centimeter each. The uniformity of the holes is a purely aesthetic point in order to get a beautiful crown of flame as from an ordinary gas stove. All!
Well, not quite of course, now we’re learning how to light it up. You need to add alcohol and close the lid, 50 ml burns for 15 minutes or more. Place on a non-flammable surface and shake lightly so that the alcohol flows a little onto the outside of the jar through the holes. We light the alcohol outside and wait until it burns out. We repeat the procedure until we get a self-sustaining flame from improvised nozzles around the can. Usually it is enough to repeat 2-3 times and everything starts working on its own.
Its operating principle is simple: the flame heats the walls of the jar, the heat is transferred down the walls to the alcohol, the alcohol boils near the walls and the pressure inside increases, the alcohol vapor comes out under pressure through the holes and mixes with air and burns beautifully. Now we put a pot, a teapot, a mug on top, or we just warm ourselves around the stove - it gives a lot of heat and burns for a long time.
For greater heat transfer, you can place a homemade alcohol lamp in a larger iron container, which would heat up and release heat:
The smaller the number of holes, the harder it is to light, but the less fuel consumption and less heat from it. A liter of water boils in less than 10 minutes. It is resistant to wind, extinguish by covering, add as much fuel as needed, otherwise you will have to wait for it to burn out or pour the hot alcohol back into the container, which is not safe.
Similar options “for one mug” from a tin can with a filler hole that is closed with a coin and from an aerosol can:
4. Wood burner for heating food
And here they offer a little more complex design burners running on wood fuel - from 2-3 cans. True, with this option you need to remember about ventilation in the tent or room.
5. Warmers made from plastic bottles
This way to warm up an ice bed or warm your feet while sitting at desk well known to students living in dormitories :))
Regular plastic bottles can be filled hot water and use instead of a heating pad.
Attention! If the water temperature is close to boiling, then when filling the bottle something will definitely happen: the bottle will begin to shrink... A water temperature of 60-70 degrees is optimal.
The experience of our employees shows that you can even sit on slightly flattened bottles, not completely filled with warm/hot water, tightly closed (!) :) or carry 1-2 bottles of hot water in your backpack to “warm” your back))
By the way, in the summer you can make “air conditioner” from these same bottles.
Freeze several bottles filled with water, place them on a tray or towel (they will begin to gradually thaw) in front of the fan turned on. The temperature in the room will drop significantly.
The most important: in an effort to stay warm, don’t forget about the rules fire safety and be careful!
Today, natural gas is the most affordable option for heating a private home, but what to do if, for example, the gas main is inaccessible to your area? Under such circumstances, it is worth considering in more detail alternative heating of a private house without gas and electricity. You can choose electricity, but, as you understand, the arrangement of such heating will be very expensive.
Modern technologies provide many opportunities to realize this vision. A private home for living has many advantages: fresh air, distance from city smog, your own vegetable garden. Such benefits of civilization as providing your home with hot and cold water, reliable, high-quality heating are the main factors for owners of country houses and private houses. We strive to make our home a real family home and do not skimp on quality building materials, we do everything reliably, for a long time. At the same time, the desire to save, invest rationally cash- this is a true, reasonable aspiration, especially if it concerns such an important factor as autonomous heating of a private home.
Most alternative heating units convert (convert) energy from fuel combustion into heat. Individual devices can simultaneously combine the functions of two units, for example, titanium and a boiler (furnace with a water circuit). Other devices (for example, solid fuel boilers) can operate and produce heat for more than a day on a one-time load of firewood. There are really many options for units for alternative heating, so let’s take a closer look at the most convenient, frequently used units that provide heating for a private home without gas or electricity.
Furnaces for heating a house with a water circuit
As mentioned above, these devices combine technical qualities boiler and titanium. They operate under steam pressure, are made of cast iron or steel, and can be used as an additional or main source of heating. The heart of the furnace is the heat exchanger, located inside the heater. According to the principle of operation, this unit resembles a solid fuel boiler. Their differences are that during operation, all the walls and channels of the furnace heat up, while the boiler only heats the coolant. It turns out that a furnace with a water circuit heats pipes and radiators during combustion, but the heated parts of the furnace itself continue to give off heat until they finally cool down.
Home structural part Such a furnace is a register (heat exchanger). It is installed inside the firebox, heat passes through it, heating the entire house, and the water heating system is supplied to it. The heat exchanger can have any configuration, the main thing is that it unhinderedly performs its main function (evenly distributes heat, maintains maximum temperature). You can make the register yourself if you have the appropriate skills for this and are “friends” with welding machine. Most often they are made to order, according to individual characteristics and oven dimensions.
Advantages of furnaces with a water circuit:
- possibility of heating large areas;
- reasonable cost of equipment;
- available fuel (coal, firewood, peat);
- no connection required electrical network, since the operation of the entire system is based on natural circulation coolant.
- low efficiency (when compared with a gas boiler);
- lack of automation (exclusively manual control).
With the help of such a stove you can heat the entire house, as well as connect a water heated floor system. When purchasing this unit, pay attention to its power.

Boilers for heating a private house
A wood-burning boiler for heating a private house with batteries continues to be popular, despite many modern heating units, presented on the market today. The main factor is the availability of fuel (firewood). Coefficient useful action modern wood boilers reaches 90%, using such a unit is no more difficult than a conventional one wood stove. It is noteworthy that the familiar gas water heater, as well as the gas boiler, were created following the example wood boiler. The difference is the source of the flame, in the first case it is gas, in our case it is wood.
The operating principle of this device is simple - water is sent to the boiler, bypassing the heat exchanger, heated and flows through the radiators. The pressure level and water flow are regulated by taps. You just have to periodically remove the contents of the ash pan, which is located under the stove.
Solid fuel boilers for heating a private home can operate on wood, coal, peat, briquettes, and suitable household waste. The so-called disadvantage of such boilers is the short period of combustion and, consequently, heat production from one load of firewood or other material.
Alternative heating option - solid fuel boiler, photo:
As an alternative, you can consider another unit that differs from standard solid fuel boilers in the volume of the combustion chamber and the special specifics of fuel combustion. Wood boilers long burning To heat houses, they can operate on one load of fuel for a day or more. Some models can work for 4-5 days when loading coal - only similar type boilers For units operating on wood, the model name ends with the letter S, while for units operating on coal and wood, the name ends with the letter U. The difference between these boilers is the material with which the combustion chamber is equipped. For units that run on coal, the chamber is made of heat-resistant metals that optimize the combustion process. The efficiency of such solid fuel devices is approximately 90%.

Heat pump for home heating
Today this equipment is gaining popularity, despite quite high price the unit itself, its installation. Heat pumps for heating a home, the operating principle of which is based on obtaining heat from environment(air, soil, water), its heating, subsequent transmission to the house, operate from the electrical network. This device does not quite fit the specifics of our topic, since we are considering alternative heating of a private house without gas and electricity, but due to its universal qualities, I decided to mention it.
This device can convert ambient energy into heat or cold (in summer it can work as an air conditioner to cool the air). As for heating, the coolant enters a pipeline located, for example, underground, where it heats up to a certain temperature, after which it releases the accumulated heat energy to the internal circuit. The main function is carried out by the compressor - the heart of the heat pump. The freon contained in the compressor acts as an intermediary between the coolant, the condenser, and the heating circuit.

In order not to describe all the subtleties of thermodynamics, it is easier to generalize the principle of operation of a heat pump - it works like a refrigerator, only in reverse. These units are environmentally friendly, economical, they can have different functions and are classified by type.
Hydrogen generator for heating a private home
Another representative of alternative heating is a hydrogen generator for heating a private home. It also requires electricity to operate. This unit is a powerful, silent, environmentally friendly device with which you can heat large areas. Its operating principle is based on the combustion of hydrogen, without polluting the atmosphere. harmful substances, and only steam is released, which is harmless to the environment.
The installation includes a boiler, pipes, the diameter of which decreases after each branching - this factor is necessary for the high-quality operation of the hydrogen burner. During operation of the generator, a catalytic reaction occurs - hydrogen interacts with oxygen and “gives birth” to water. Thus, thermal energy is released, which is sent to the heat exchanger, while the efficiency of such heating is 96%. Heating a private house using hydrogen generator can be produced either independently or additionally, interacting with other heating installations.

Solar collectors - an alternative heating option
The emergence of new technologies motivates us to keep up with the times. People have learned to benefit from the environment and use it to improve their quality of life. Today, one of the most successful developments in the field of heating installations can be considered solar collectors for heating a home. These devices are able to provide you with heat at any time you desire. The sun's rays are one of the most accessible sources of heat, and with the help of collectors they can be converted into thermal energy necessary for our needs.
During such a transformation, two types of energy can be obtained - electrical and thermal. Using solar collectors, you can heat water, heat your house, and install a heated floor system. Photovoltaic modules (another name solar panels) have a slightly different principle of operation - they are aimed at generating electricity. In the summer, with the help of solar collectors, you can provide your home with hot water, and with the onset of autumn and spring - with heat. It is worth considering that in winter the devices are ineffective, since the sun no longer shines so intensely.
How to make heating in a private house using solar collectors? These units have a long service life (more than 15 years), they must be installed on the south side of the roof, and its area must be at least 40 square meters. At the same time rafter system the house must be reliable and durable, since the collectors have significant weight. Best this heating be considered at the stage of home design - multiple installation nuances require special attention. Naturally, you need to carefully calculate the number of devices themselves and their power.

The standard unit includes a vacuum manifold, a controller, a coolant supply pump to the manifold storage tank, volumetric water tanks, a heat pump, and an electric heating element. Solar collectors for heating a house are expensive and require significant material investments. initial stage. The payback period for such a system is 7-10 years. It must be taken into account that sun rays do not appear at our request, which means that these units cannot be the only source of heat for the house. Along with their installation, another heating system will be required.
To summarize, I would like to say that alternative options home heating can allow any owner to provide his country house or private home with heat and create comfortable living conditions. Even despite the significant financial costs at the initial installation stage, the units described above are a more profitable alternative to traditional gas heating. We should not forget about the level of safety - statistics of accidents due to the use of gas heating speaks for itself. Some devices can be full replacements gas version, and some will complement existing heating systems well.
Alternative heating of a private house without gas and electricity is a reality today, but do not forget about increasing the overall energy efficiency of the house (minimizing heat loss, eliminating all heat leaks).
