In order to go directly to the rating of boilers, you must first figure out what they are and by what criteria are distinguished.
Classification
1. By the method of burning fuel:
atmospheric (open combustion chamber);
inflatable (closed combustion chamber).
2. Depending on the efficiency of using the heat of combustion:
ordinary;
condensation.
3. On the principle of work:
single -circuit (only heating);
double -circuit (heating and hot water supply).
4. Depending on the installation site:
hinged (attached to the wall);
floor (installed on the floor).
Foreign manufacturers of gas boilers
It has traditionally happened that 3 groups are distinguished among European manufacturers: German, Italian, etc. But in the market of heating devices, manufacturers such as: French, Korean, Czech, Japanese.
German products:
Bosch
Vaillant
VISSMANN
Budes.
Viallat, Viessmann, Budes – honorary leaders in the production of heating boilers. “Bosch” replenished their ranks a little later. German equipment is of high quality and accuracy of execution.
“Vaillant” began its activities to issue in 1894. The advantage of products is the possibility of applying and adaptation in Russian conditions. Each model undergoes quality test, has all the necessary certificates, thereby providing for itself reliability and long service life. In our country, the devices of this company of a hinged type were loved. For convenience, a liquid crystal display is built.
“VISSMANN” – the products of this company are characterized by a unique heating system of the coolant while using two heat exchangers. This increases the efficiency and productivity of the device. The company also manufactures components for gas devices.
There is a only “but” – high cost, but these are justified funds in exchange for reliability and higher quality.
The entire assortment of German equipment has the following characteristics:
automated process;
high quality and reliability;
a large number of functions;
increased efficiency;
the presence of new technical solutions;
durability;
Attractive design.
Italian heating devices are also popular, they are inferior in price to German boilers. Trade marks:
Baxi;
Ariston;
Beretta.
“Beretta”-belong to the economy class group. They are inherent in reliability, made of high -quality materials and have compliance with world standards. The boilers of this brand have an air intake camera and a collector. The camera does not allow condensate, and the collector does not allow the appearance of frostbite on the chimney. For boilers, natural and liquefied gas are used.
“Ariston” as “VISSMANN” applies the operation of two heat exchangers, so the heat transfer and efficiency increases. The installation of such a boiler is very simple. Is popular in more than 150 countries. The main characteristics are based on simplicity, reliability and durability. The range of products produced by the company is limited, but the pricing policy attracts many consumers. Paul and wall installation boilers with condensation and ordinary type of operation are produced.
“Baxi” is perhaps the only trademark who is ready to compete with German manufacturers regarding quality and reliability. Quite widespread in Russia. The range of products offered is very wide and covers all devices of the heating system. For example, heat generators represented by Baxi are fully automated and are as effective as German.
Beretta and Ariston first appeared on the Russian market, at their low cost showed good results, however, after a while, the demand for dual -circuit gas boilers of these manufacturers has sharply decreased. Negative reviews concerned the quality of components and reliability of the boiler. Time has passed, and the trust rating has not been restored, and, despite the democratic price of equipment, the demand for them has not grown.
Of the manufacturers belonging to the “Everybody” group, the Slovenian brand “Protherm” is sharply gaining momentum. The technique is not so equipped with new developments, but the price and reliability at the proper level. Service service is also available in pricing policy.
Asian manufacturers also rightfully occupy their niche in the heating instrument market. “KitUrami” is the largest manufacturer of heating equipment in South Korea and every year more and more confidently goes to the rank of “world leader”. In their production they try to introduce their own developments and technologies.
Dakon – a Czech manufacturer, began its activities in 1949, and in the 70s he was the largest representative in his field. Later, the German company “Budes” bought the main share. Today, Dakon produces a wide range of products: gas, electric and solid fuel boilers; cast iron and steel boilers, as well as floor and hinged.
Not so long ago, the products of the Spanish manufacturer Roca entered the domestic market. He has been conducting its history since 1917, when cast -iron radiators have just begun to produce, and currently electrical, solid fuel and gas boilers, air conditioning systems, automation and even accessories and much more have been represented.
Choosing a gas boiler for yourself is not an easy task, since the market has a huge selection of manufacturers, each and which is characterized by their own characteristics. The head should be the quality and reliability.
