  • The above causes me to wonder: of what I have, i.e. gas and electric; which is the cheapest fuel with which to heat water?

    Gas will always be much cheaper if you have a 'normal' electricity tariff.

    Gas costs 3p - 4p kWh(allowing for boiler losses) Electricity 8p -10p kWh

    If you have Economy 7 electricity(which is doubtful if you have gas CH) is is closer to gas.
