I would be interested to see the results.
This is what is so annoying about the present society in which we live, in that one cannot always trust people to do what you have paid them to do.
I would agree that increasing the LWT is likely to reduce the instantaneous COP value when the heat pump is operating in continuous mode, but it may ...
@lucia The better option would be to get the cavity filled correctly.
One way to try to reduce cycling frequency would be to raise the Leaving Water Temperature (LWT) by means of the Weather Compensation (WC) offset. Thi...
@toodles Page 20 of the attached manual provides a detailed breakdown of the model number.
Most heat pumps will cycle when the OAT is 10ºC or above, the frequency is cycling may be dependent upon quite a number of parameters. If I have tim...
Does the attached manual cover the model in question?
I think the best that can be obtained from assessment is the approximate heat loss, since the actual heat loss will vary with changing weather conditi...
