John Siegenthaler: The 'net' effect

Air-to-water and water-to-water heat pumps are destined to claim increasing market share in future hydronic systems.
John Siegenthaler, P.E.
John Siegenthaler, P.E.
October 28, 2021

The Coefficient of Performance (COP) of a heat pump is essentially the same concept as the thermal efficiency of a boiler (e.g., the desirable output divided by the necessary input).

John Siegenthaler: Your customers don’t pay for COPs

Understanding coefficient of performance.
John Siegenthaler, P.E.
John Siegenthaler, P.E.
