Just posted a W on this. If using Weather comp, what to do overnight?

 

serms a clash between it being colder outdoors, so flow temp goes up. But then rooms need lower temp overnight..

@benseb once you are at temp the power needed drops. That said you can adjust by a degree if you want to. There isn't much in it, but it seems to be marginally more efficient to drop the thermostat over night. In the end the pump will have to work harder later on to get the temp back. I think keV looked into it

are there any experts in the U.K..

 

i’d happily volunteer on the back of my 3-400 installs over 15 yrs on boilers (the approach is the same for both boilers and heat pumps)

Professional installer
