Oil-filled radiator finally competing with gas central heating for one room?

Far better off coupling the battery to an Air to Air Heat Pump.

there was a thread somewhere where someone did a return on investment calculation for that but i can't for the life of me find it now. would be interesting to see how the figures have aged. i think (very vagely) it was air to are wasnt a great investment but ground source was even with the higher cost. but you do have to think about how insulated the house is and vampire loads in summer and all that higher mantanence stuff compared to a 'standard' boiler that you can set and ignore most of the year.

I am talking Air to Air i.e. aircon unit, cost less than 1k, not a full house air to water system at about 10K. With an aircon unit of 700W you will get 2-2.5kW of heat, it's still a single room solution unless you open the door ( if 2kW doesn't overheat your room you need some serious work on insulation).

Thanks everyone.

I haven't done any calculations, but I think the air source heat pump would be the biggest benefit for people who have both the battery storage and also PV panels: if you're generating and storing decent amounts of electricity already, I'd imagine that using that electricity to heat your house would be cheaper than paying for gas.
