Heat Pump Installations

£15 a day to heat - Activair 7kw

Hello, I’m looking for some help/advice this is my current set up I know it’s the whole tank situation is horrible and the insulation on the outside pipe work needs redoing but ideally need recommendations for some one to come and service the system and possibly set it up properly as I believe it really isn’t set up to run efficiently for example last winter it was costing nearly £15 a day to heat the house and even then the house never actually reached 20 degrees, the heat pump also used to freeze over due to the auto defrost not working right I had to keep manually forcing it to defrost. The heat pump was installed by elite energy around 2.5 years ago and after arguing with them constantly I give up 😅 any help or recommendations are greatly appreciated based in County Durham north east

20kw Heliotherm split

Single phase 100amp, so choice was limitied Designing without a full repipe over the four floors - 42mm primaries ran on the basement floor to split the load, then using existing 28mm up on the first floor and second floor. Pump selection, running different pipe runs to see what estimated resistance I have and settled with the Wilo Maxos which is my favourite by far pump out there. Control strategy, balancing system performance with non excessive energy use. Eventually settled with a buffer and Evo home running the secondary pump, Heatpump is running via buffer sensor only and either side don’t interact. How water - house was split into two before, Combi and direct cylidner. We opted for a fresh water module, so it late loaded hot water via another 500l buffer. Radiator selection, in keeping with the house build cast irons were preferred but with Heatloss we couldn’t do it everywhere. So we settled for downstairs with cast rads and then k3 radiators upstairs to satisfy a 50° flow temp. Expansion I chose 4x 18l Staticos and charge pressure of 1.5 because of head height. Best vessel on the market in my opinion, no idea why anyone would use any other vessel.
