Innovative solar powered radiator - will it work?
Ok, so i live in a rented flat (apartment) in London UK. Its a small flat but its old and doesn't have a gas heating system so i'm stuck using expensive electricity especially as the windows are single glazed and winter is on the way! Brrrrr! I desperately need a cheap and effective heatsource
Now I know solar water heaters can be suprisingly effective even in the cold and that got me thinking. I have a south facing garden. Couldn't I use the sun to heat the flat?
Specifically, I was thinking, can I use a solar water heater to heat an insulated water tank, then use the tank to heat a radiator after dark? (See diagram below)
Bear in mind in temperature during the day at the moment is 11 degrees. Will enough heat be generated to make the system viable? I.e. will the water heat the tank hot enough during the day to keep the room warmish for a evening?
Other pressing questions:
Do i need a commercial panel or will an instructables model work?
Oil filled radiator or water filled?
Will it auto-siphon or will i need a pump?
cheers a million guys and gals!!!
