Nov 16, 2018 · Condensing theory, How to maximise domestic condensing boiler efficiency. To maximise the efficiency of your domestic boiler is very simple, turn the flow temperature down. This doesn't mean that it releases less energy overall to heat the property, but rather can use less gas to release the same amount of energy.Get Price
The P-h diagram plot of this system follows, and we notice on the diagram that the high pressure feedwater is heated from state (6) to state (7) before entering the boiler, while a mass fraction y of the bled steam is cooled from the HP turbine outlet state (2) to a subcooled liquid at state (8). The subcooled liquid is then passed through a Get Price

A boiler's AFUE (annual fuel utilization efficiency) rating makes the assumption that heat lost through the jacket and spilled out the draft hood is dumped into the living space. If the boiler is in an unfinished basement or garage, however, this heat is actually lost. Water heater efficiency ratings, on the other hand, assume near-zero Get Price
water temperature will improve the boiler's efficiency. Latent Heat: Latent heat is the heat that is added or removed due to a change in phase from a solid to a liquid or from a liquid to a vapor. In the case of a condensing boiler, it is the heat that is removed from the flue gases when the moisture changes from a vapor to a liquid.Get Price
