CONDENSING HIGH EFFICIENCY BOILERS

increases overall efficiency with the recovery of latent heat contained in the flue gases. This latent heat in a non-condensing boiler is unfortunately sent to the exterior through the chimney. All this wasted heat recovered with the "ASOLUTE AS SERIES" boiler can reach up to 25% increase in efficiency compared to a non-condensing boiler.

Efficiency factors in natural gas fired steam boilers

When this boiler works at 90% efficiency, thermal power becomes 53 Gcal/h. Due to a high oxygen level in the boiler, a 1.4% loss in efficiency occurs and thermal power reduces by 0.74 Gcal/h to 52.3 Gcal/h. The economic loss is $24.4/h. Effect of radiant heat loss on boiler efficiency A steam boiler has a higher temperature than its

AFUE and Real Boiler Efficiency | Annual Fuel Utilization

For example, the well insulated low mass boiler with thermal purge anticipates the end of the heat call and pumps the heat left in the boiler out to the hot water tank or a heating zone to capture energy that would otherwise be wasted. The result is very high annual efficiency, even in the spring, summer, and fall when boilers run much less
