Methodology For retrofit space heating and combination heating and hot water boilers, there are three

Evaluation of a field test with retrofit heat pumps

Highlights A field test with heat pumps in existing buildings in Germany was analysed. The heat pumps were compared to gas-condensing boilers regarding energy efficiency. The efficiency of heat pumps primarily depends on the mean temperature lift. Air source systems in the field test often are less efficient than gas boilers.

Cleaver Brooks Retrofit or replace boilers? Returning

The answer to this dilemma has often been the use of condensing boilers with touted efficiencies of 90-95%. In many cases these boilers replace existing non-condensing boilers at a considerable CapEx expense when we consider the removal of the old boiler and the cost of replacing it with a considerably more expensive condensing unit.
