Thank you. If this works it will be a great step forward. I agree. Good news. Makes it all look more feasible. Here's another high temperature heat pump which may do the trick:
See page 4 for a succinct summary of its features.
Nevertheless, it does appear that more conventional units operating at lower temperatures are more efficient. There's a lot to think about!
Thanks. These claim a 10-12 kW capacity, depending on model, compared to 6kW from Vattenfall, and don't need the extra water tank that the Vattenfall model uses to boost its evening output to 11kW. So they would be much more realistic for me. However, it's a shame they use R-32 refrigerant, which is an HFC. Not the worst by a long way, but still a powerful greenhouse gas. On the question of operating temperatures, the brochure includes fan convectors, which can replace radiators and run at a lower temperature. Does anyone have experience of these?

Heat pumps don't make financial sense especially with looming electricity pice cap hikes. It may mean less energy consumed at home but swapping a burner for electricity ends up way more expensive despite the massive saving in joules needed.
Solar PV is the way, or if you have time and a source of wood the govt will pay decent money to burn as much as you can as fast as possible. Sadly our money for the latter ran out in summer.
I would like a heat pump, and we even have a 2000l heat store water tank ready to go (the footprint is smaller than that of a bath though, even with the insulation, and most houses would manage with 1000 litres as stated - but it obviously weighs over a tonne per 1000l), but I can't for the life of me get the numbers to work out without assuming electricity prices unrealistically fall substantially compared to oil

Solar Doesn't work for me , in December 2021 my system generated a total of 38kWh ! from a 4.2 kwh system
PEOPLE ARE FIXATED ON SOLAR IS THE ANSWER , it isn't except for those with a detached house or a south facing roof#

As far as I can see all the other "answers" end up costing more and may not achieve much from an energy saving POV either by the time conversion and transport inefficiencies are considered when swapping gas to electric. Also the single month of December probably isn't representative of your solar array over its lifespan.. I'm also considering wind but my wife won't be convinced ..

November, December January and February , all do not produce enough power on my 4.2/ kWh array to meet my current needs let alone the increased demand from a heat pump.
If I assume the mythical COP of 3. between May and September my Panels produce enough to supply my heating needs for the winter months so in effect if December was as sunny as June I could run a heat pump from my panels to keep the house warm
Lookup Ripple wind farms, if you are interested I think I may have a referral code

It could go in a poor-quality field or on a factory or warehouse roof...

my God what a bleak life we are condemning our elderly to I don't disagree with your analysis, but you've overlooked 'Pension Credit':
Whether it is acceptable to expect affected pensioners to grovel for such payments is another matter. Anyone who has experience of claiming benefits of any sort from the DWP (or helping someone to do so) will know just how demeaning the whole process is.

pension credit will boost
your weekly income to £177.10 if you’re single
your joint weekly income to £270.30 if you have a partner
You may get extra amounts if you have other responsibilities and costs.
The top up and extra amounts are known as ‘Guarantee Credit’.
so even if we take £177.10
multiply by 4.3 to get monthly figure still only £761 a month
of course the sillyness is that Pension credit unlocks other benefits
lets say you get £10 a month pension credit.
then you also get a free TV licence with my council Id get 75% off my council tax, and rent, and the warm home discount
So a pensioner on pension credit may well be better off than a pensioner on a full state pension

The silly part is its binary as to whether you are eligible, and therefore also binary for unlocking the other payments. If you are only a few quid (or even one) over the level, not only do you not get the credit but you are also cut off from all the others. So in proportional terms, it can result in the loss of access to quite a LOT of money. Mother in law in exactly this position (and yes I know I sound like a broken record as I've mentioned it before).

I have a friend over by a few pounds ( About £15 ) a week
But pays full council tax as a result, and given council tax in my area is £100 a month after the single person discount he is actually just on that one measure £35 a month worse off
let alone he doesn't get warm home discount, free TV licence etc
