Half of homes need heat pump by 2040

And do you know A2A isn't promoted (well it's not quite as bad as it was) in Scotland for the same cooling reason?

Because cooling would be used so much in Scotland... /s

The biggest problem as i see it is small bore pipes particularly if in concrete floors.

For most houses i see air/air HP as the ideal solution. Fraction of the capital cost and a fraction to run without the disruption and bigger rads. Also the climate is warming.

And the Gov will not support them because people might use them in summer for cooling when PV output is at its greatest/excess.

Fingers crossed A2A support may also be changed now/soon. I'm hoping that will announced too, so I can bore my friends and neighbours even more about how easy it is.

There is a laundry list of reasons why A2A is unpalatable to the powers that be:

1) They are obsessed with DHW and spaceheating being combined into a single system.
2) They cannot fathom a system that isn't monolithic. EG with a HP (A2A or A2W) sized for typical conditions and a SH or WBS or even resistive, to augment in very cold conditions or for infrequently-used spaces.
3) They are terrified that you might use it for cooling.

It is really silly because I manage to heat my 5-bed house with a single A2A together with resistive on ToU. The gas combi has been used only for DHW for the last few years. I'd like to attach my microbore central heating system to a teeny 3-4kW A2W to provide a bit of background warmth and take the strain off of my resistive. However, I'm yet to find a suitable unit.

Hi Stinsy, I'm hoping this line will lead to something:

Support the rollout of air-to-air heat pumps that can also provide a cooling function.

Given that this line seems to have come true:

Remove the 1m boundary rule, enabling heat pumps to be installed within 1m of the property boundary.

But I've no idea what (or how little) that word 'support' means?

This one seems to be the cheapest and readily available from a reputable manufacturer from many places in the UK, but I don't think it modulates. You could try and parallel up a couple of zones, like upstairs and downstairs to increase the flow rate.

Looks decent, needs an external pump and controller though...

The Grant Aerona 3 6kW is a bit more but can work without the controller and has an internal pump. Saw a used one on eBay (had been used temporarily) a while back but it came and went without me being in a position to use it...

How about,

From the same place we got our A2A ones from and has controller and internal water pump.

Regarding these changes, has anyone seen more on it yet? I've found a few news pieces like the original story, from the same time, but nothing since.

Has there been anything 'official' yet, and especially on what the 'support' for A2A units may be? Perhaps the support is simply to apply the same PD rules, but I was hoping for some sort of financial support, so folk can do what I and others on here have done already.

I seems its only for England at the moment and I only think its for planning (PD), not financial support.
