[QUOTE="johnb2713, post: 546721, member: 35153"] The poorly insulated homes make no difference when comparing to gas, if 6000 kWh of heat is required it doesnt matter what the source, the requirement is the same. Heatpumps have an average COP of 3, so the 30p kWh becomes 10p pretty much the same as gas. The Tepeo boiler can charge up on off peak at 9p kWh again near enough the same as gas BUT you gave to take the inefficiency of the gas boiler into account so you lose 20% or thereabouts with that and then add the standing charge for your gas meter. All in all it should cost slightly less than gas IF either of the aforementioned technologies is used, if it's resistive heating then its madness. [/QUOTE]
