THE FLOOR HEATING BOILER

the Heat would be desirable that it was condensation, this system is to cool the products of combustion (smoke) before escaping into the atmosphere going to give up their heat to the heating, this cooling causes condensation water vapor content in them and this process allows you to recover much of that heat that is normally dispersed in the atmosphere with traditional boilers, resulting in savings in fuel consumption;
condensing boilers can only be used with radiant systems with low temperatures (eg. systems floor heating), resulting in savings of up to 30%.
