The differences between the production of a condensing boiler or a traditional “boiler” aren’t measurable only with the recovery of a part of the heat given to the steam , but also with a substantial control of a sensitive heat losses through gas, thanks to a low products temperature of combustion. The choice to make a condensing boiler to operate with low temperature helps to pull down the radiation losses, tied to the difference of temperature between surroundings environment and heat exchanger.
