The boilers of high performance (under consumption) use the conventional fossil energies, like gasohol or natural gas, for its operation. They can be integrated perfectly to any system of heating already installed, occupying the place of the old boiler.
Its outpost technology allows to regulate the heat contribution to the volume of asked water and the outer temperature, adapting perfectly to each state and obtaining a perfect combustion. They present/display very high yields, around 95%.
Of this form one is able to take advantage of the generated heat to the maximum, reducing the losses, the consumption of fuel and the gas discharges, providing a power and economic saving that oscillates between 20 and 30%.
Its versatility makes suitable to be complemented with thermal solar receivers. Thus, a solar system of heating with a boiler of low consumption and receivers can get to save between 50 and 60% of energy.
The boilers of condensation only work with gas, and its technology is able to take advantage of to the maximum the heat the combustion smoke.
Its compact and reduced design, to diminish the losses, and mural (of wall) allows to save spaces being arrived to eliminate the quarter of boilers and to optimize the inhabitable surface.
It is known that in the combustion of a gas water steam is generated. The water steam has a high power content that yields the condensed being and who can be taken advantage of.
The smoke of a conventional boiler is expelled to the atmosphere to 150 - 200 ºC. If they cool off until the temperature of condensation, around 55 ºC, also they suppose a heat contribution. The sum of these contributions supposes a 11% of the total of the energy that has the fuel.
By this it is no wonder these boilers obtain yields around the 106%. This does not mean that more energy of the one is generated than takes the fuel, but that the yield of the normal boilers is calculated without considering this energy.
The cause that the smoke leaves to an inferior temperature to the 55 ºC does not mean that this type of boilers cannot give hot water to more temperature. This heat serves to preheat the water before making contact with enemy with the combustion chamber.
It agrees to mention that if radiators are used it must guarantee that the water return is to an inferior temperature to 50 ºC, to obtain to the complete cooling of gases and its condensation. Therefore, this type of boilers adapts perfectly to the heating by radiating ground.
