Heat pump COP and preheating
Has anyone ever seen an analysis that indicates the benefit of having an air source heatpump run more before the nightly temperature drop in order to obtain a higher COP than later in the night?
A similar pre-charge could be done for cooling before the outside temp rose a lot.
In the past with leaky poorly insulated houses I don't think this made much sense, but now with some very tight and well insulated houses I belive it would be beneficial.
The main trick is to mine weather report data and control the thermostat based on COP curve, energy loss rate, and heat schedule.
Also does anyone know where one can locate Trane heatpump COP's?
