RESEARCH OF EFFICIENCY OF WALL-MOUNTED BOILERS WITH SEALED CHAMBERS USED AS FLAT HEATING SYSTEMS

The research encompasses the field testing of wall-mounted boilers with sealed chambers integrated into flat-heating systems operating in different modes. Results of field tests of items without the indication of their producers and equipment brands are provided. The testing procedure involved a double-circuit wall-mounted boiler. Its capacity was 30 kW, and it had a sealed natural gas combustion chamber. The main regularities of its operation were identified and boiler heating parameters were assessed when the boiler was in operation at full capacity. The findings make it possible to state that the reduction of capacity of the heat generator causes an increase in the heat loss. Besides, the results of calculations make it possible to perform the heating system analysis and to define the area of application of various systems of heat supply. The principal decision based on the basis of the above analysis is the decision to install an independent or a centralized system of heat supply
