The only way to accomplish this is to have an entering boiler water temperature of less than or equal to 130F. Simply stated, if return water to the boiler is higher than 130F, condensing cannot occur; even if the boiler modulates and is at its lowest firing rate. This is determined by the laws of physics.

The Running Costs of Heat Pumps (2021) | GreenMatch

May 06, 2021 · For example, a ground source heat pump can reduce energy bills by at least 26% compared to a new gas boiler. Some of the key factors affecting the running costs of domestic heat pumps are: Coefficient of Performance ( COP ) - with typical values of 3.5 to 4.5 (ground source heat pumps) and 2.5 to 3.5 (air source heat pumps), it can save up to
