With the approach of the heating season, owners of country houses are beginning to think about heating. But it is desirable to think about the purchase of a wall-mounted boiler and its choice at the design stage of the gas supply system. Classification will help to make the right choice.
Classification of boilers
- By functional features. Divided into one and two-circuit depending on the functions performed: heating of water for heating or also for household use. Double-circuit wall boilers, equipped with a tank for water accumulation, happen with a boiler or flowing. In instantaneous water is heated in the pipe of the unit as it warms up. In the boiler - in a certain capacity. When you turn off the gas in the tank will retain a certain amount of hot water.
- By type of chimney. If there is a chimney in the room, then a wall-mounted boiler with natural draft will do. But the oxygen will burn in that place, where it is installed. With good ventilation, this can not be considered a problem. Otherwise, forced traction will be required. The combustion chamber will be separated from the environment, and in the chimney will be 2 pipes: to supply oxygen and to eliminate carbon monoxide.
- For mounting type. The gas wall unit will perfectly cope with heating of the small room. It is ergonomic, attractive in appearance and low price. Gas tile appliances are needed to heat a large area. A separate area is required for operation. But to save it, you can install a boiler for boiling water.
- According to the principle of work. Condensing gas heaters are characterized by high productivity. It is also ideal for underfloor heating. The principle of its operation is the same as a convection boiler, but requires less fuel.
Annually, heat production companies sum up, make a comparative analysis. Find out, what equipment, which manufacturers were in demand in the market. Based on the results of the analysis, a rating of popular models of gas equipment is compiled, the reasons for its demand are explained.
Stable market demand is observed for new generation double-circuit gas wall boilers. This equipment has a quality security system and modern automation. Every company applies innovative solutions, offering unique samples of gas equipment.
Rating of wall-mounted boilers
The rating of gas heating boilers is based on the following parameters: producer, construction, technical parameters, functionality and cost. The main producers and recognized leaders in the ranking are Germany, Italy, Korea, France.
Germany
The ranking of elite heating units is headed by German companies. The leaders are Bosch, Valiant, Buderus, Wolf і Viessmann. The offered model range is wide enough and allows to get a copper taking into account individual features of autonomous heating system..
Heat engineering from German manufacturers is in well-deserved consumer demand due to its special reliability, quality workmanship, stylish design and compactness. During operation, gas units do not emit annoying noise. They are easy to install, easy to operate. Even low gas pressure or minimal water volume will not interfere with their operation.
Disadvantages of German boilers
- Heat engineering takes a very long time to heat up. Hot water will go away in just a minute.
- The chimney is very often clogged. We need to find time to maintain it.
- According to other indicators, German heating technology is impeccable.
Italy.
Italian units are in second place in the ranking. Their brands are Ariston, Ferroli, Baxi, Saunier, Nova Florida. High quality products. It has a reasonable price (middle price segment). Double-circuit gas wall units, designed for autonomous systems, make up the vast majority of the range.
boilers have the following benefits:
- The wide range allows you to easily choose a gas unit for the apartment, house or specific premises.
- Ferroli and Baxi boilers are equipped with a self-diagnostic system. Other brands have a reliable and simple management system. It is extremely convenient for daily use of the boiler.
- There is no overuse of fuel. Boilers operate even with a sharp decrease in gas pressure and low atmospheric temperatures.
- You can install it anywhere, without allocating a separate room for equipment. It is mounted quickly. But you can not do the installation yourself. Installation should be performed only by a specialist in the installation of double-circuit gas boilers.
France.
French manufacturers close the top three. Their brands are Chaffoteaux, Frisguet Chappee and De Dietrich are reliable, durable and high quality. These aspects are in the first place in the manufacture of machinery.
Not inferior in quality and the Polish brand Termet, Elektrolux from Sweden and the Slovak brand Protherm. Korea. The Navien brand enjoys well-deserved success among consumers. Gas domestic heaters of this brand are universal and reliable, perfectly fit into the system of autonomous heating. Specialists of the concern base their work on innovative design of heat engineering.
Technical characteristics of boilers differ exceptional qualities:
- boilers are safe and compact;
- work well at low temperatures;
- work does not stop at sharp decrease in pressure of water or gas.
The automatic system does not allow the boiler to defrost. The boiler independently sets the necessary operating modes. It always works rationally and economically. Does not require constant monitoring. Comfort and convenience in the operation of gas boilers allowed the Koreans to rise to the level of European manufacturers.
Russian brands
Russian manufacturers "Gazapparat", "Signal" and "AZGA" continue to defend their position in the market of thermal equipment. These gas boilers have a fairly high rating. They are also competitive. But produce only large heating systems, used for heating suburban settlements, production shops and shopping centers.
Remember before buying a double-circuit gas unit, that the brand is not the main thing. It is necessary to get acquainted with that, how the equipment behaves during operation in specific conditions. Examine customer feedback on specific unit models. Ask for the opinion of neighbors. After all, voltage drops, poor water quality and other operating realities can significantly reduce service life, guaranteed by the manufacturer of heat engineering.
