The best non-volatile gas heating boilers rating. The best wall-mounted gas heating boilers rating. Calculation of the power required to prepare hot water

Modern market really saturated heating equipment from different manufacturers. This also applies to heat generators using natural gas. Even if you know all the necessary parameters well, choosing among many brands will not be easy. In this article, we decided to compile a general rating of gas boilers, the purpose of which will be to help the average user decide and make the optimal choice.

Types of gas boilers

For a general understanding, we first present a brief classification of heat generators. They are divided into different types according to several criteria:

by combustion and exhaust method flue gases: these are units with an open (atmospheric) and closed (supercharged) combustion chamber;
according to the efficiency of using the combustion heat of gas: there are 2 categories - conventional and condensing boilers;
by functionality: we mean the ability of a heat source to heat water for the needs of hot water supply, this is one - and double-circuit gas boilers.
according to the installation method. According to this criterion, heat generators are divided into wall-mounted (suspended) and floor-mounted.

Advice. Before you start choosing a brand, you should select a unit according to all the listed criteria.

On the Internet you can find a variety of ratings of gas boilers, but we decided to present a rating of the most popular brands in the post-Soviet space, dividing them by country where the manufacturing companies are located. So, to begin with -

Western European manufacturers

It just so happens that residents of the CIS countries divide European brands into 3 groups: German, Italian and “all the rest”. We, too, will not break away from the people and will take a look at the most famous brands of these groups one by one, and start with the German ones:

BUDERUS;
VIESSMANN;
VILLANT;
BOSCH.

For reference. Since 2003, Buderus AG has belonged to the Robert Bosh GMBX concern.

The first 3 brands are leaders and trendsetters in the field of heating boilers; BOSCH joined them a little later. They all make the best gas boilers you can think of. The corporate colors, blue for BUDERUS, red and gray for VIESSMANN, are well known to a wide range of users.

The first 2 brands offer the widest range of heat generators of all types and capacities. At the same time, VAILLANT and BOSCH focused on wall-mounted boilers. And the reviews from homeowners sound very eloquent: if you take a floor-standing unit, then BUDERUS or VIESSMANN, and if you take a wall-mounted unit, then VAILLANT or BOSCH is better. But they all have the following characteristics in common:

high quality products;
reliability in operation;
constant implementation of the latest technical solutions;
high efficiency (efficiency up to 97%);
availability of the widest range of functions;
a complete set of process automation tools.

Unfortunately, while leading the rating in terms of quality, German boilers firmly hold the lead in cost. This is the highest price category and products of these brands are not available to everyone. Somewhat cheaper than others VAILLANT and BOSCH, but not much. Boiler maintenance is just as expensive.

If we compare boilers made in Italy and Germany, the former clearly win in price. Most popular brands:

BAXI;
ARISTON;
BERETTA.

The BAXI trademark can compete with the “Germans” in reliability and quality; it is not without reason that it has gained wide popularity in Russia and other post-Soviet states. The range of their products is equally wide and covers the entire domestic sphere - from simple floor-standing boilers to wall-mounted condensing boilers. Just like those from German manufacturers, BAXI heat generators are efficient and fully automated, from ignition to control by telephone or via the Internet.

Having just appeared on our market, the brands ARISTON and BERETTA showed good performance at affordable prices. Over the years, the ratings of double-circuit gas boilers of these brands have fallen, and many negative reviews have appeared regarding the reliability of operation, the quality of components and materials. At this time, the products, despite their reasonable cost, are not in great demand. Wall-mounted gas boilers and water heaters from these manufacturers are well known; floor-standing models were purchased much less frequently.

A brand that stands out sharply from the group of “everyone else” has firmly settled in the middle price category and is gaining popularity in our market at an accelerated pace. This is the Slovenian brand PROTHERM, which has already gained a reputation for its reliable heating equipment. Wall-mounted and floor-standing boilers offered by the Slovenian manufacturer may not be as stuffed with the latest achievements in the field of heating technology as the “Germans”, but they are affordable, reliable and adapted to the realities of the CIS countries.

Positive reviews about PROTHERM boilers come not only from users, but also from the craftsmen who install them. This suggests that service The technology is also relatively inexpensive.

Asian manufacturers

Among Asian heating boilers, we can distinguish 2 well-known brands and a whole group of products from the Middle Kingdom, which are quite difficult to list, and there is no need to list them. People have long had their own opinion about Chinese technology; to confirm this, we will add that buying a Chinese boiler is a lottery, no matter how attractive the price. We will not review them, nor recommend them; everyone makes the decision to purchase these products for themselves.

One of the world-famous South Korean manufacturers of wall-mounted and floor-standing gas boilers is KITURAMI. We must pay tribute to the products of this brand: they are very reliable and high-tech, have all the same functions as the “Germans” and are just as well automated. The problem is that KITURAMI also “bites” on price and then the eminence of the brand begins to play a role, and here European brands benefit.

As for the reviews, they are mostly positive, that is, this “Korean” is on the same level as BAXI and BOSCH boilers. Also, the design of the unit is adapted to low gas pressure and other delights of the Russian outback. Definitely recommended for use.

Another, already budget version gas boiler for the home - a Korean unit of the NAVIEN brand. It appeared on our market relatively recently and has taken root well since then. Known for its wall-mounted heat generators, which have a full range necessary functions and a good degree of automation. Despite the obvious budget, it received many positive reviews. Breakdowns do occur, but they can be fixed quickly and inexpensively. NAVIEN is the equipment that people talk about - the optimal price-quality ratio.

Conclusion

As you can see, choosing a gas boiler is not easy even among manufacturers. If funds allow, you should not fall below the average price category, where the “Chinese” and boilers of the CIS countries are located. We did not talk about the latter, since they do not top any ratings. By and large, such boilers are a body made by us, equipped with imported automation, sometimes again Chinese.

Such equipment is quite durable and safe. To help in choosing the best option for heating equipment, a rating of gas boilers was compiled, which were especially popular in Europe and among our compatriots in the first half of this year.
