Cheaper to run than gas central heating when used for heating? I need a new boiler, would a few cheap air conditioners do the job cheaper?

Or 1:2.65, even if true, my gas to elec cost is 1:4.48 so the sums just don't work out.
What about bottled gas or oil, for people not on mains gas? Would it be better (Especially at night, on E7)?

I've just paid 2.95/unit at 10.5kW/l for oil (30.98p/l). Our electric is 5.01p/unit or the E7 8.48/2.57p/unit so the E7 is marginally cheaper. Oil will have to drop to 24.4p/l to match the night E7 rate, but generally we need heat outside of the E7 period.
Prices ex VAT.
No, the figures quoted are "best case" for inside and outside temperatures. For average figures look for 2-4 times worse.
classic oversight. Look at the daytime prices with E7, way above flat rate prices. E7 gives an almost ok deal with one hand, then gets you with the other. Dont use E7 unless thres really no other option.
Heat pump efficiency depends on temp differential. The greater the differential, ie the colder it is outside, the more efficiency drops, as the further uphill, thermally, the heat has to be pumped.
