> Anyone have any numbers to back this up or refute it? Don't know where you are, but here in the UK right now the split is 34% wind, 29% gas, remaining <other> [0]. If you migrated from a modern condensing boiler with 90% efficiency to a heat pump with 300% efficiency (1 unit of electricity outputs 3 units of heat), then with the gas condensing boiler you're getting 0.9 units of heat per unit of gas, and with a heat pump you're getting 0.87 units of heat per unit of gas, _plus_ 1 unit of heat from wind. Over the last year, the _majority_ of the time the split in generation sources looks like this. It's occasionly heavier on gas, but for 11 months of the year, it's a no brainer, and I don't think that outdoes the 1-2 weeks per year that you're using an almost equivalent amount of gas.
