Theo, have you found an up to date comparison between storage heaters
and ASHP?

Why would anyone install storage heaters - the worst of all worlds?

Indeed. Low capital cost is all they offer. ASHP is half the running
cost or less, but you really need UFH to use the low temperatures. And
mega insulation to allow for low heat output.

logical implications, of the principles upon which it is based, and of
the ultimate consequences to which these principles will lead. They must

Yes Storage heaters are cheap to install, and expensive to run. ASHP can be 10K to buy the unit. (https://www.ebay.co.uk/i/11412500930...kcid=28&chn=ps)
That one is 11kw, from a wee google a typical oil boiler for a three bedroom house is 30kw.
If that one has a 10 year life, like the one my mate was going to buy, that is £1k per year for the machine, then the electricity is above that. I only just switched my heating back on, it is about 8 degrees during the day. The air is pretty wet too. I have not seen figures for using ASHPs in ****ty conditions. If you are paying for the system and the electricity, it may be a closer run thing between ASHP and storage heaters.
