Default Solar Energy to heating

Can anyone post me in the right direction, what i want to do is run electric heaters on solar and/or wind energy to warm 3 rooms im my house. The only thing i can ever find it how to heat water, i am thinking more in the way of electric heaters?

Can this be done.

It can be done but is very inefficient. When heating water you can collect about 800W per SqM as opposed to 50W with photovoltaics. You'll also find that the cost of a couple of kWs worth of PVs prohibitive (but you will find lots of nice companies that will happily supply you).

Yes, a REALLY silly idea - particularly in the UK!. As Pommie says, there are good sound reasons for using the sun to heat water for your heating - not to mention you're going to be looking at probably 10kW to heat three rooms!.

If you want to save energy for heating I would suggest improving your insulation and using a heat pump.
