At what boiler water temperature can achieve better energy-saving effect?

25 Feb 2022

It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.

Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
