At present, the hob is electric (wipe-clean flat-surface type)

Which one of those scenarios appeals? NB: Take into account the
current enormous rise in heating oil price, which might not drop for
several months.

We have an external propane red bottle (two actually) to power our gas
hob instead of electric, but that's just because we find a gas hob nicer
to use, nothing to do with heating the house and price of oil.
