A gas boiler running on propane is capable of heating a room no worse than a unit configured for regular mains gas. When installing equipment, you must remember about the oxygen regulator, since according to the standards, more of it should be supplied to the unit than to a conventional boiler. In order to guarantee uninterrupted and safe work With such a device, boilers are equipped with special devices that stop the operation of the device in the event of an emergency. Another feature that significantly distinguishes a liquefied gas installation from a natural gas boiler is that the burner in it has a significantly smaller diameter, and, as a result, lower gas pressure that comes from the cylinders.
Heating a private house with gas cylinders: consumption of the necessary fuel
As practice shows and consumer reviews indicate, for a house of 100 m², approximately 3 - 2 cylinders of gas per week are needed, provided that the capacity is 50 liters. From this calculation you can determine how much fuel you will need to heat your country house. For example, for a house of 200 m², the amount of gas will increase to 4 containers per week. If your house has an area of about 50 m2, then 1 cylinder will be enough for you.
A gas-cylinder installation of a gas boiler room for a private house using liquefied gas cylinders for 100 m² requires the simultaneous connection of at least 4 cylinders - 2 working ones, plus 2 reserve ones. For an area of 200 m², 8-10 containers are usually enough. To ensure absolute ease of use, your connection equipment set must have a ramp.
Alternative heating with gas from cylinders: making the right choice
If you have a boiler that runs on propane to heat your dacha, then it is very difficult to accurately determine the gas consumption it needs. Often this indicator depends on the method of insulating the room. If the winter is harsh, the figure will, of course, increase. If you have insulated your house well enough and there are no severe frosts outside, then you will use gas with great savings.
To calculate the approximate propane consumption for heating a room, use the formula, which shows that to obtain 1 kW of energy you will need about 0.1 kg of propane.
Fuel consumption gas boiler running on propane will please you much more than you would have to pay to heat the same house using electricity. It is considered the most economical to use main gas, but it is not always possible to connect to the public centralized system gas supply. In this case, heating the room with a propane boiler will be the most sensible idea. When purchasing a heating unit, be sure to take an interest in user reviews, consult with experts, and ask consultants to give you full description device and the possibility of its conversion to liquefied bottled gas. Before you finally make a decision in favor of installing gas equipment, be sure to carefully weigh all the important arguments, calculate fuel consumption, and only after that proceed with installation steps.
Gas boiler from a 50 liter cylinder: how long will it last?
Often owners country houses, as well as real estate within the city, are being abandoned central heating and the main gas pipeline in favor of alternative options, providing for the possibility of heating premises using liquefied gas. It is easy to use and more affordable. The radiator and battery heat up no worse.
Modern gas heating of premises using boilers operating on liquefied gas involves the use of a number of parts, consisting of several types of equipment and a heat supply system. Only the main unit in this design still remains the boiler, which is responsible for generating heat.
As with standard heating appliances, a gas boiler that operates on liquefied gas allows private homes to provide room heating, as well as hot water supply, through its combustion. Often this heating equipment is compact in size, high performance And good performance Efficiencies that sometimes reach 95%.
In addition, such a device has the following advantages:
- Low cost;
- Allows you to significantly reduce the funds spent on heating and hot water;
- Can operate at low gas pressure;
- Has low fuel consumption;
- Allows you to turn off the heating when it is not needed.
If you use a gas boiler that runs on propane, then the fuel consumption will be approximately as follows: 130 sq. m taking into account qualitatively installed windows And entrance doors, will be in the area of one cylinder weighing 50 kg for 2 or 3 days. If your desired room temperature is at least 21-23, and in addition to this you also need hot water, then you will have to refill 3–4 cylinders per week. If your home is smaller, fuel consumption decreases proportionately.
Features of heating with liquefied gas
Choice heating units, which run on liquefied gas, is simply huge today. Here you can find products from both domestic manufacturers and goods from various global brands.
Each model you meet has its own unique operational properties and their corresponding cost. So that the heating process country cottage using bottled propane gas from a gas tank has become economical and efficient, you need to choose the right type of unit and take into account its main operating features and technical capabilities.
In order for a propane heater to work properly, it must be connected correctly and the nozzles must be replaced. This equipment worked out quite well. Owners willingly install it country cottage who do not have the opportunity to connect to a common gas main or independent heating. This type heating is very practical in operation, has a low output coefficient harmful substances, is compact, and the efficiency is quite high. Propane-butane gas is an excellent alternative to conventional natural gas.
When purchasing a boiler, consider the following:
- Type heating device. Heating devices using liquefied gas can be single-circuit or double-circuit. The first option is suitable exclusively for heating, while the second type, in addition to heating, also provides hot water supply.
- Efficiency In fact, all units that operate on liquefied gas have high performance Efficiencies that reach 90-94%.
- Power. This indicator is one of the most important parameters characterizing the type of heating equipment. It is necessary that the unit you choose can easily provide hot water and heating all rooms in the house.
And, of course, the manufacturing company is an important indicator. Practice shows that it is highly desirable to give preference to companies that have successfully existed in the market for a long time and have positive reviews users.
Heating from a gas cylinder (video)
Owners of private homes should be aware that heating boilers run on liquefied gas. It is possible to switch to a different operating mode without any problems, and they will work using a different type of fuel, or rather main gas. To do this, you just need to replace the burner, nozzles, remove the gearbox and replace some other equipment. You can do all this with your own hands, however, in order to properly install the connection, you must follow the rules for using propane installations.
Everyone faces the problem of how to heat a house if there is no way to connect to the central gas pipeline. There is a way out of this situation - heating with gas from cylinders. Gas from a cylinder is no different from main pipeline. There are no prohibitions on the use of this type of room heating. It is gaining more and more popularity. The price of solid fuel is constantly rising. Not everyone has time to prepare firewood for the winter, because they need to be cut and stored. This is a labor-intensive process. It is much easier to fill several containers and bring them to a country house.
Pros and cons of balloon heating
Heating a dacha with a gas cylinder is considered autonomous heating. The vessels can be easily delivered by car to the most remote villages, thereby solving the problem of heating rooms. The cost of this type of heating requires significant financial costs. Use of gas balloon heating will be beneficial when taking into account the following factors:
- Room up to 100 sq. m.
- Reducing heat loss (the house must be insulated).
- There are other heating devices.
- This type of heating is temporary; after a while there will be a connection to a gas pipeline with natural gas.
The advantage of using such heating is that when connected to a central gas pipeline, you will not need to buy another boiler. Such boilers operate on both liquefied and natural gas. Change injectors and reprogram the system. By purchasing one equipment, you can use two types of heating.
Connecting your home to gas cylinders will not require significant preparatory work. To connect to the central gas pipeline, a lot of work needs to be done in the building.
To heat a dacha with a gas cylinder, containers must be transported to a gas station. This will cost additional money and time. The use of such fuel requires compliance with safety precautions; liquefied gas is explosive. Individual room heating using gas cylinders must be installed correctly.
The disadvantage of this method of heating buildings is its price. IN different regions Fuel prices vary from country to country. Gas will cost more in one area and cheaper in another. Purchasing low-quality liquefied gas will increase fuel consumption. This method of heating rooms is not cheap. Sticking with everyone possible ways To save fuel, you will need at least ten vessels per month.
Specifics of balloon heating installation
To heat your home with bottled liquefied gas, choose the right boiler. Not every heating equipment can operate on this type of fuel. The device must have a built-in burner. Buy equipment with a power of 10-20 kW, pay attention to the heated area.
Follow safety precautions and choose proven, high-quality gas cylinders. Place them outside. In winter, when the air temperature drops, the vessel may freeze, which will lead to a decrease in pressure in it, the gas will not evaporate. Its supply to the boiler stops. Therefore, the gas cabinet where the equipment is located must be insulated and installed on the north side of the house. The gas cabinet should be as dark as possible.
To insulate a gas cabinet, run a special hose from the boiler room through which heated air is supplied using fans. It is prohibited to heat the gas shield with heating cables. For gas heating, use at least four vessels.
To ensure that heat is evenly distributed throughout the building, make the calculation correctly required quantity radiator sections. On average, for one section of a standard aluminum radiatorcan separate from200 watts of heat. If we take the area of the house to be 100 sq. m. and a ceiling height of 2.5 m, then you will need a boiler with a capacity of 10 kilowatts or more. Therefore, 50 radiator sections will be required. An accurate calculation can be made taking into account heat loss through windows, walls and roofing. If you doubt the accuracy of the calculations, contact a specialist.
Principles for choosing a boiler
For heating country house gas cylinders buy a reliable boiler. To use liquefied gas Buy boilers with a special water circuit as fuel. Pay attention to the devices intended for use natural gas. Having purchased equipment for natural gas, it is enough to change the burner or nozzles, and it can be used for reduced gases. When the need for heating with bottled gas is no longer necessary, install other nozzles and heat the building with natural gas. When using autonomous heating with liquefied gas, select boilers with high efficiency.
The stores are very large selection boilers You will find equipment not only domestic producers. There are many models developed by foreign manufacturers. Therefore, the price of such equipment may vary. Everything will depend on the manufacturer and technical characteristics devices. To make heating your building with propane economical, choose the right equipment.
Connection diagram to the boiler
The use of gas boilers without their conversion to the use of liquefied gas is strictly prohibited. Natural gas is supplied through large nozzles; for liquefied gas, nozzles of smaller diameter are installed.
For correct connection vessels to gas system buy a gearbox. Using this device, gas is transferred from liquid state into gaseous form, and then fed to the boiler.
You can buy a reducer that fits all supplied cylinders or buy such equipment for each. It's cheaper to buy one general device, but such equipment is less safe. To connect several tanks to heating equipment, install a ramp. The ramp selects gas from some vessels, and when the gas runs out, the boiler switches to spare tanks.
Choose gas pipeline pipes with a thickness of at least two millimeters. The pipe that passes through the wall must be in a foamed case. To connect the reducer to the gas pipeline, buy a rubber-fabric sleeve. If you do not know how to properly connect the gas system, contact a specialist.
Gas cylinders are placed outdoors in a special ventilated gas cabinet. They can't stand in the sun. If you are going to install containers in the boiler room, they should be no closer than two meters from the boiler.
Using a gearbox
An obligatory part of the gas cylinder system is a reducer - this is a device that is used to reduce pressure . Installing a reducer is mandatory because the pressure in the tanks is constantly changing due to different air temperatures outside and the amount of gas remaining in the cylinders. Be very careful when choosing a gearbox. Pick up correct performance this device. Gearboxes that are switched automatically are used with special protection. When the pressure level rises significantly, the protection opens the relief valve.
Principles of cylinder refilling
Gas cylinders for heating a house are filled with a mixture of propane and butane gas. Gases are in liquid form. The type of mixture that is filled into the vessel is influenced by the season of its use: summer or winter. In winter, the air temperature drops, so the containers are filled with a winter technical mixture of propane and butane.
The vessels are filled to eighty percent. If it is completely filled when the air temperature rises, the vessel will burst. Gas cylinders with a volume of 50 liters are used. The containers are filled at the gas station. If you do not have your own transport, order delivery by a special vehicle that delivers filled vessels to villages.
Gas consumption from cylinders
Many people are interested in the question of whether heating with bottled gas is profitable or not. Before installing it, calculate the amount of fuel needed to heat the rooms. Maybe it will be more profitable for you to install a solid fuel boiler. If the house is large and poorly insulated, then it is better to use other methods of heating the house.
To heat a building up to one hundred square meters with bottled gas, two or three vessels per week with a capacity of fifty liters are needed. When you leave, set the heating temperature of the building lower, then you will need one gas cylinder for a week. To save fuel, experts recommend using automatic devices for the heating system. You can set the temperature at which it turns on heating system. No need to run around to adjust it yourself. When the temperature in the rooms drops, the heating system will turn on, and when normal temperature the heating will be turned off. There will be no unnecessary fuel consumption. To save fuel, it is recommended to reduce gas supply at night.
Such heating will cost more than a central gas supply, but will be cheaper than eclectic heating of the room. In extreme cold, fuel consumption will be much higher. Control how much gas remains in the vessel in order to fill it in time. Always have several spare filled cylinders so as not to be left without heating your home in winter, in cases where you use only this method of heating buildings.
What is better to use for gas storage: gas holder or cylinders
It is not necessary to use cylinders to store liquefied gas. You can use gas holders - these are large tanks made of steel. One filled tank will be enough to heat the rooms in cold weather.
The disadvantage of a gas tank is that problems may arise with its delivery and storage. To fill it up, you need to call a gas truck. Additional costs will be required to place the gas tank underground.
A good compromise would be to use a mobile gas tank, which combines both a capacity of about 600 liters and the ability to tow it to a gas station. With average gas consumption, this will only have to be done 2-3 times a year.
Gas cylinders are easier to refill. They can be taken to a gas station at any time, but a car with gas must first be ordered, and then wait for it to arrive. To heat your house with liquefied gas in cylinders, install several vessels. One will not be enough.
Ways to reduce gas consumption
Insulating windows can reduce fuel consumption because the building will lose less heat. Also use other elements to reduce gas costs.
- It is necessary to control the temperature of the room in which the gas boiler is located. If indoors, where to be gas devices will low temperature, there will be problems with the operation of the boiler. The same air temperature must be maintained in the boiler room and heated rooms.
- It is necessary to fill cylinders with high-quality gas at proven gas stations. Various impurities will increase fuel consumption.
- Use automation in the gas system. Its use will reduce heating costs.
- There may be a leak in the gas system. This will increase gas consumption for heating the house. Buy and install sensors that will give signals when gas appears in the room.
Use of gas cylinders and compliance with all safety measures
Gas in cylinders for heating buildings must be stored in special prepared iron containers outside. If you don’t know how to properly make a gas cabinet for cylinders, buy a ready-made one in a store. This type of gas collects at the bottom when leaking. You may not feel its accumulation in time. And if the cylinders are placed indoors, a high concentration of gas can lead to an explosion. Cylinders cannot be installed in basements or cellars.
Cabinet for cylinders
The cylinders are installed vertically. When equipping a place for storing them, you need to provide holes for ventilation. So that if it leaks, it will not assemble. Carefully check the plug connections on the gas pipeline. Such connections are installed in places where other connections cannot be used.
If you decide to make a boiler room to store gas cylinders, make the walls from non-combustible materials. Provide ventilation. Do not place flammable materials near containers.
Gas cylinders are prohibited from being filled to more than eighty percent. If you fill it completely during frost, and then put it in warm room, the vessel will explode. If corrosion appears on the container, do not use it. From compliance with all safety measures for use gas equipment, the lives of the residents of the house depend.
It is beneficial to use bottled gas to heat a dacha or home as a temporary alternative, with its further conversion to use natural gas. The most convenient to use are vessels with a volume of fifty liters. The advantages of gas cylinder heating are that the containers can be easily delivered by car even to the most remote village. To refuel them, just go to the nearest gas station. On average, to heat a house with an area of up to one hundred square meters per week, you will need two gas cylinders.
This type of building heating is environmentally friendly and causes less pollution. environment. And when using solid fuel, a lot of smoke appears.
Paradoxical as it may seem, but in modern world There is not yet a central gas pipeline everywhere. And to heat their rooms, people have to use wood or electricity. But there is another way - heating the house with gas cylinders. This is a good alternative to solid fuel and electric heating if it is impossible to connect a private home to the central gas pipeline.
Although heating with liquefied petroleum gas propane or propane-butane is somewhat more expensive, in terms of its characteristics such fuel is practically no different from gas passing through the main line. A gas stove for heating a house from a cylinder is often used in a private house or country house, where the heated area does not exceed 100 sq.m. Let's consider the main features of balloon heating.
There are no direct prohibitions or restrictive measures on autonomous heating of a private home with gas cylinders. However, heating a home with liquefied gas from a cylinder is not always rational, since obtaining thermal energy in this way requires significant expenses.
Heating a house from a gas cylinder is beneficial only if:
- heated room area up to 100 m2;
- organizing good thermal insulation of the home;
- minimizing heat loss.
The arrangement of heating a private house with gas is carried out using ordinary 50-liter cylinders with propane or butane, which are compressed to a liquid state.
In summer and winter, different mixtures of flammable substances are used:
- SPBTTL (flight combination);
- SPBTZ (winter mixture).
In winter, the tanks must be constantly monitored, as interruptions in the fuel supply are possible due to the difference in boiling temperatures of the mixture components (propane -40°C, butane 0°C). As a result, at a temperature of, for example, -10°C, the pressure in the vessel will drop below the level needed for normal functioning systems. Then the cylinder will have to be heated to at least 0°C so that the butane begins to evaporate.
Attention! It is strictly forbidden to heat cylinders that are located in a private house at subzero temperatures with heating elements or heating cables.
Advantages and disadvantages of balloon heating
Heating a private home with bottled gas has both advantages and disadvantages over other heating options.
First we give undeniable advantages heating with liquefied gas:
- high efficiency with significantly lower labor costs compared to solid fuel heating;
- the ability to convert a gas boiler from a conventional cylinder to mainline equipment;
- absolute autonomy and independence of the functioning of the balloon system;
- long service life of equipment (15-25 years);
- presence of demand for cylinders in the secondary market - containers are easy to sell if they are not needed.
In addition, cylinder heating allows you to heat water in a private house for domestic needs.
We also list the main disadvantages of such a heating system:
- cylinders must be refilled regularly, approximately every 2-3 weeks, which is inconvenient and costly;
- if the system is not organized correctly, gas consumption increases significantly;
- the need to create suitable conditions for storing containers.
Thus, organizing a heating system on cylinders can be very dangerous if certain operating conditions of the equipment are not followed. Therefore, vessels can only be stored in a ventilated area without a basement. It is best to place the cylinders in a separate building.
How to connect the cylinder to the boiler?
To assemble a heating system on gas cylinders, the following equipment is required:
- gas boiler with a special burner for liquefied fuel;
- gas cylinders;
- gearboxes;
- ramp for connecting several containers;
- shut-off valves;
- pipes and hoses for connecting the system.
As a rule, a gas boiler with a water circuit is used as a heat generator. Moreover, a special boiler model is not required; you can simply replace the burner or nozzles. The power of the heating device is selected in accordance with the area of the room, but the efficiency of the device should be as high as possible. Excellent choice will become a gas condensing boiler.
Attention! Install cylinders in the basement or basement forbidden. It is better to place them in a metal box with holes for ventilation.
Vessels can only be placed in a horizontal position. It is better to place a metal box on the north side of the site in a shaded place.
For the boiler to function correctly and efficiently, it must be connected to 4-5 cylinders at the same time. To equip a gas pipeline, you will need a pipe with a wall thickness of 2 mm. At the place where it is installed, a sleeve is installed in the wall, the diameter of which is 20-30 mm larger than the cross-section of the tube. The space between the sleeve and the pipe is filled with polyurethane foam.
The cylinders are connected to the system through a reducer, which converts the liquid back into a gaseous state. This can be done in two ways: one reducer for all vessels or one pressure regulator for each cylinder. The implementation of the second option ensures complete safety, although it is more expensive.
To increase the interval for refilling containers, it is better to connect several vessels to the boiler at once through a ramp, which divides the cylinders into a main bundle and a spare one. First, gas will come from the main group of tanks, and when the fuel runs out, the boiler will switch to the reserve group. When the main link is updated, the heater will reconnect to the main group.
Attention! Observe most important rule safety: it is prohibited to fill the cylinder more than 80% of the volume, since the mixture of propane and butane has a high percentage of expansion, and when the volume is filled to more than 85%, there is a high probability of the vessel exploding.
When assembling and installing equipment, pipes and hoses, all connections, connectors and fittings must be checked for gas leaks using normal soaping.
Can the cylinder be replaced with a gas holder?
Instead of conventional 50-liter cylinders, it is allowed to use a more capacious steel container for storing liquefied gas - a gas holder. The volume of some of these tanks is often enough for the entire heating season.
However, heating a home with liquid gas cylinders is considered more convenient, since it is much easier to deliver fuel in more compact vessels. In addition, for a gas tank it is necessary to carry out a large amount of work on digging the site, which will result in additional financial investments.
At the same time, the use of a gas holder eliminates the need to simultaneously connect several containers at once, since one cylinder cannot provide sufficient evaporation for normal operation boiler
Pressure control reducer
The pressure in the cylinders is constantly changing, and its value depends on many factors:
- number of cylinders;
- composition and temperature of the mixture;
- remaining liquefied gas;
- distance of a group of vessels to the boiler.
The reducer is used to convert and maintain stable gas pressure in the vapor state.
You need to select a gearbox for a heating system based on two main characteristics:
- performance;
- working pressure.
The rationality of heating a private house with gas cylinders depends on the fuel consumption of the boiler. Therefore, the performance of the gearbox should not be less than the pickup capacity of the heating device.
The operating pressure of the reducer is also selected in accordance with the characteristics of the boiler equipment. If the pressure produced by the reducer is too high, the operation of the heater will be disrupted. The pressure regulator is made for 20, 30, 37, 42, 50 and 60 mbar.
When connecting vessels using flexible hoses, you will need a reducer with a herringbone fitting. And when connecting cylinders using combs and rigid pipes, you will need fittings with threaded outlets.
In addition to their main purpose, automatic devices are equipped with protective elements that are triggered if the pressure rises to a critical level. Then the relief valve opens.
How much fuel is burned?
Heating a house whose area is approximately 100 m2 with liquefied gas can be done using a boiler with a power of 10 kW. In order to obtain 1 kW of thermal energy, it is necessary to consume 100-120 g/min of liquefied gas at 100% boiler load. If the cold period extends to 7 months, then the approximate estimated fuel consumption for the entire season will be about 5 tons.
But in reality, the volume of expenses will be almost 2 times less, thanks to the automation, which switches the equipment to economy mode when the air temperature in the premises has reached the set value or guided by the timer settings.
If we compare the costs of heating a summer house or private house from a main gas pipeline, then heating with liquefied gas is about 5-6 times more expensive. But nevertheless, in the long run, it is cheaper than heating from electricity.
If we take into account the prices for liquefied gas, then heating a country house or cottage using cylinders is not the worst alternative to electric and liquid fuel systems. Especially in cases where the region has problems with solid fuel or it is quite expensive.
Heating with liquefied gas is the most rational decision in the event that there are plans for gasification soon settlement, due to the fact that then there is no need to purchase a boiler. In addition, there is an opportunity to practice using a gas boiler.
How to store gas cylinders in winter?
In the case where the cylinders are located outside the house, then winter time at negative temperatures, the pressure of the liquefied gas drops, and the boiler may simply turn off. In order to avoid this, the cylinders must be installed in a special cabinet that is insulated with non-flammable materials and equipped with good ventilation.
Freestanding ones are also suitable for this purpose. non-residential buildings with a minimum heating level. During the operation of cylinders, it is necessary to observe following rules safety precautions:
- Gas containers must not be heated with open fire;
- There should not be a cellar or basement near the cylinders, because during a leak, the liquefied gas sinks down, it has no odor and can accumulate to an explosive concentration;
- It is highly recommended to install a gas leak detector;
- storage of full cylinders is permitted at a distance of at least 10 meters from residential premises;
- It is prohibited to store empty cylinders in the house;
- Once every 4 years, cylinders must be checked for leaks and integrity.
Thus, heating a house with gas cylinders is not in a profitable way heating However this great solution as a temporary measure until it becomes possible to connect to the central gas main.
