Almost all mounted boilers can automatically resume work if the electricity is turned off, and then re-applied. Double-circuit boilers have a built-flow heat exchanger or storage water boiler for hot water. Mounted boilers come with an open or a closed combustion camera.
Another important advantage of the mounted boilers is the special design of burners that are not sensitive to fluctuations in gas pressure in the main line. Of course, the thermal capacity of the boiler will depend on the size of gas pressure.
Boilers and water heater review
The power of wall water tank heaters are from 12 to 35 kW, and the performance of hot water heaters in combi boilers from 8 to 15 l / min. For a combi boiler with an tankless water heater danger may be “bad” water with a high content of dissolved impurities. In this case, the heat exchanger can quickly “overgrown” with mineral impurities and can damage. If you intend to use the double-pressure boiler, be sure to make the analysis of water and if necessary, bring it to the normal structure of a filter system. If cleaning is not possible for some reason – it is better to install an external storage unit. The design of mounted boilers provides for such a possibility. Hot water becomes larger, however, require a bit of extra space to install the boiler.
You can use any water heaters. The selection criteria can be an aesthetic notions of buyer, cost and amount of coolant radiators in them. The smaller volume of the coolant, the smaller the thermal inertia of the system and hence can be quickly and accurately adjusted by means of automatic temperature control smokers. Cast iron radiators in this sense is the worst option. For individual houses can recommend steel panel radiators. They are the cheapest in terms of 1 kW of heat output and are durable enough to stand-alone heating systems.
Tubes may be made from any known materials: steel, copper, plastic, and metal-tube. For plastic and metal-tube important factor is the selection of compounds. If the tube wiring is hidden in the monolith of floors, walls or sewn facing materials, the use of threaded connections should be excluded or each of them must be available for inspection and repair.
