help choose how to heat my home

We have no gas option. For years we have developed and extended our bungalow - now large, 4 bed, detached. Heated by storage heaters, most fairly modern. Like that no boiler, no pipes, easy to add as extended. 12 yr ago added solar panels to heat water (immersion for the winter, on off peak electricity). Now have 4kw pv solar panels in situ. and am wondering if there is a more economical/efficient means of electric central heating that would be more controllable and economical to use. How expensive and disruptive would it be to install it? Independent advice is tough to find.:(

No, because an electric boiler will run on a single rate tariff rather than E7, which will be around 300% more expensive than your existing cheap rate E7.
All electric heating is the same efficiency, i.e 100%.
Your other options are oil, biomass, LPG.

Insulate the heck out of the bungalow and stick with the storage heaters, especially if you are in the house most of the time.
Have you looked at say a wood burning stove.
I guess air or ground source heat pumps may be worth investigating.
Don't touch expensive German electric radiators though.
