Heat pumps work on the priciple that for every 1kW of electricity used to power the heat pump, the heat pump will produce 4kW of heat, the physics are different as the two work in completely different ways
I understand that.
As I have already stated I am talking about LATENT HEAT or to use the more modern term " Enthalpy of Transformation".
Yes, but the latent heat in a condensing boiler has been produced by the boiler within its specified capacity, the boiler simply catches this latent heat and extract most of the heat from it, I say most as some still goes out the flue, but this heat is still from the heat that the boiler produced, the fact that a small amount of this heat escapes out of the flue proves that the boiler has to be less than 100% efficient 95%-98%
