Hi Guy,
I am researching for couple options for cost efficient option of heating our house, and one thought came in my mind is, What about solar heating??? As now a days we are already using solar for water heating then why not for heating house specially during daytime.
Does anyone have any thoughts, ideas or link to web where I can have a look. I mean what sort of solar panel, size etc..etc.. and which heater to use etc.
thanks
DM
