Apologies in advance as I'm far from an expert - hence why I'm seeking advice!
We had a Mitsubishi Zubadan 14KW fitted in Oct 2023. It works really well in some rooms and others (definitely bigger and with higher heat loss) it's been challenging.
I don't think the system is well balanced as our loft K3 rad doesn't get much heat at all - so I'm hoping an engineer will come and help after all our failed attempts at balancing the system.
My question today is - if the heat pump flow temp is at 40 degrees - but I measure 33 degrees maximum on the hottest radiator's flow pipe.... shouldn't it get 40 degrees? (return pipe is around 23 degrees, but delta will depend on the radiators at the moment, I have as low at 2 degree delta on some radiators). Just wondering if some rooms struggle to heat up because the flow temp is too low to start with...
Thank you
