Is fitting a multi-split heat pump a reasonable job for a fairly well experienced DIYer? I realise it needs a dedicated power feed to the outdoor unit, but other than that?
Access is really good - it's a concrete floored bungalow with a big loft. There's no existing system at all. So fitting pipes to radiators would involve drops down into each room, which is the main reason I'm looking at an Air-to-Air system. I'm thinking the pipes/cables to the outdoor unit would drop from the soffit directly above. Pipes to the indoor units would just need a short length of trunking up to the ceiling. No need for any core drilling at all.
Is the refrigerant gas even obtainable? I'm wondering if it's restricted, as it is a greenhouse gas.
I've seen lots of US-based YouTube videos indicating DIY is a sensible option. I understand I need a vacuum pump and torque wrench for the fittings.
Does anyone have experience of fitting one of these? I get the impression they're pretty popular in lots of the world but not very much in the UK, although they seem to be getting more attention recently.
I know there are low cost pre-filled DIY kits, but I'd worry about reliability and parts availability. I'm hoping I could buy a posh Daikin system and fit it myself, obviously after much more research and buying of tools.
Alternatively, I wonder if there are hybrid DIY/Pro options, e.g. I fit everything then a HVAC engineer and sparky visit to do their bits.
By the way, we don't have mains gas so that isn't an option. I don't want solid fuels or oil due to the fumes, mess and many other issues. Please no conspiracy theories about heat pumps being a big con or whatever!
Has anyone else done similar?
