Air to Water Heat Pump…
I had an Air to Water Heat Pump installed at my home in 2021, the actual pump was fine with no problems at all but the installation of the pump and the fitting of the pipework and thermal insulation was a nightmare. It was identified after someone from HIES who checked it that the orientation of the pump was wrong and the thermal insulation on the pipework was not the correct thickness or had not been fitted at all and the radiator in my Bathroom was undersized, Eventually Mike Kellett "the Professor" at Ask Renewables came to my home to observe what was wrong. He informed me that what had to be done was for the pump to be raised over my Water Butt and sat on a special steel upstand. a few weeks later the workmen arrived and I was told that Mitsubishi would not approve lifting the pump onto an upstand and the pump MUST sit on the floor. The workmen then installed a second Heat exchanger in my upstairs Airing cupboard this additional exchange was not shown on the approved Single Line Diagram and rather they then installed a larger radiator in my my down stairs hall. I have spent 3 years reviewing this with Safe World Insurance my Insurance Backed Guarantee Company who admit that they know nothing about Domestic Central Heating or Heat Pumps.
We must have clear approved rules, Heat Pump installation is after all Government approved
