My idea for home heating
is for every house to have its roof covered in solar panels (not to generate electricity, as that's inefficient, but just solar collectors) which would then heat water during sunny times. The water is then stored in a huge insulated tank underground, and the heat extracted during the cooler months using a heat exchanger or heat pump if required, and used to warm the house.

That, coupled with effective insulation, should make the running costs of heating a home very low.

Of course there's the installation and maintenance to consider, but it's an idea.
