Heat Pump Questions

Just jumping on board, my outside space is effectively a narrow side return. Then a publicly accessible path. Then a small patch of garden.
How would that work? 

Heat pump in the garden with pipes run under the publicly accessible path to your house, perhaps?  Heat pumps won't be suitable for every locale, I would have thought.

That's not going to be happening - far too much digging up and trees in the way.

So if I have old 1980s storage heaters does it mean I wouldn't be eligible to get the £5K heat pump grant? Is it only for people with gas boilers?

Until the scheme details are published, no-one knows the eligibility requirements. And I've not seen them anywhere. It could be months until we know the answer.

Another key question is whether or not the scheme will include air-2-air heat pumps? At the moment, RHI is for wet systems only. Replacing storage heaters with a heat pump not be a cheap or sensible option.

Government policy to date has been to exclude any system capable of cooling from the subsidies, supposedly to discourage domestic air conditioning. I wouldn't get any hopes up on that front.

I'd be tempted by and A-2-A unit, in addition to an ASHP, for cooling once I'm solared and batteried up. There'll be plenty of spare leccy to run it at the time it is most needed.

Obviously, we'd never have a good summer again.

Why would the government give you £5K to replace a non-fossil heat source with another non-fossil source?
Your heating is already zero carbon at the point of delivery, though maybe less so at the point of generation.
Its' safe to assume that it will only apply to people with gas, oil, or LPG boilers.

That I doubt. I have a 7kWp array and a PW2. On a cold dank December day, solar output has been as low as 300Whs. A fully Grid-charged PW2 will only supply 13.5kWhs which I suggest is not sufficient to power a home and run A-2-A. Cooling in the summer shouldn’t be an issue.

I meant in addition to ASHP for heating. On the sunniest days in summer I'll have leccy coming out of my ears from a 10-12kWp array. I'd use the A-2-A for cooling then. I realise that array won't keep the heating going in the middle of winter

Because you will use roughly a third of the electricity you were using with storage heaters, electricity generation is not zero carbon and with everybody moving to electric cars we might find electricity is in short supply in general (and in higher demand at night).
