How important is flow/return temp and what can we control?
Hello,
I’m early in the ASHP journey and have done lots of reading around but cannot fathom this out.
My ASHP has a very low heat loss- say 2 or 3 degrees.
Will this affect the efficiency of my heat pump? What should I be aiming for if so, and what can we change to improve this if it’s the case?
I’ve a 14 kWh Mitsubishi ashp and controllers.
Thank you.
I don't have anything original to contribute, but have you seen this thread with the same problem and a similar if not the same heat pump? https://renewableheatinghub.co.uk/forums/renewable-heating-air-source-heap-pumps-ashps/heat-pump-delta-t-too-low-2c
