We looked at heat pumps and it's not really viable (without a much higher cost) as it'll involve removing half the kitchen and finding somewhere for a water tank as the old boiler is a combi, for now at least a decent new boiler makes much more sense, being off the gas grid would be nice but not going to happen this time round.
Have a look at the new Heat Geek Mini Store. Clever heat pump hot water tank that can fit in a kitchen cupboard.
That is quite interesting, maybe not for us for now but looks useful for moving away from gas in general. I guess you'll not be taking advantage of economy 7 rates so much not heating a big tank over night but good if you've got solar PV and no batteries to self use the electric.
