High temp air source heat pumps?

[katie279]

Ok guys,

Now I'm all solared and batteried up, I'm now looking at heating.

I know low temp heat pumps are pretty controversial at the moment, dubious in terms of ROI and very disruptive to both your house (rip the place apart for new radiators, insulation) and your lifestyle (plan your heat 24 hrs in advance!).

However these high temp ones are now being released in the UK, which are just straight swaps for your oil/gas boiler and look pretty compelling.

Has anyone got any experience/ thoughts on these? After oil has risen from a £230 bill to around £1000, I'm keen to free myself from that and love the idea of heating through solar/cheap electricity rates using batteries....

High temperature heat pumps can cut your bills and carbon emissions without you getting new insulation or radiators. Here’s how they do it.

Take that as a no then....

Gonna investigate these more - seem to be eligible for government grants/rebates too, so that'd be extra £7500 potentially off.

Need to try and work out how many KW my heating would be in winter...!

Ah makes sense - I think oil is a bit simpler as we've naturally got no 'mains supply ' needing plumbed out, just a big tank outside.

Have sent a few emails around, so will see what comes back!

Yes if you have the space then it seems like it's sort of going nicely hand in hand with the other systems you have, and not having to pay to remove a gas supply is a bonus (honestly this seems like a scam cost to me!).

I have a multi-split AC setup 3 internal units one external, it's not a central heating system but uses the same refrigerants mentioned, R32.

Considering scheduling them to heat the house a little overnight on the cheap Go electric rates in the winter, although the impact may dissipate a bit by the time I actually wake up, it should in theory give a better baseline heat. New build house so keeps heat in pretty well.

Yes, I'm even mulling adding a third battery to cover this.. ie charge for cheap or store solar from previous day and discharge during day to heat as required.....

Hey all - I looked into this in some detail and posted in various forums to get expert views and the like. The short of it is, I'm leaning towards holding fire for a year or two as it appears the whole heat pump technology (especially high temperature ones) are just too new and constantly evolving - think of it like buying the first iphone....

I'm really keen to wait for a straight swap heat pump that can reach high temperatures if required (ie so I don't need to plan 24 hours ahead when I want to be warm!) - there are several on the market now, but they're very much first editions and have a few reported bugs, so I'm going to wait for at least the '2nd editions' of these and then jump onto the bandwagon!
