Hi flatters,I want to install a solar heating panel on the roof of our multi-storey block, to heat my own apartment. The panel would heat air in the sun, pump it down a duct added to the outside of the building using a solar-powered fan, and into my apartment.
Must admit I don’t see anyway I would agree to this if I was asked to approve it in an apartment setting. This is space heating of the apartment and OP is planning on pumping heated air down the side of the building into his apartment.
Pumping air involves large capacity ducting which is going to be an eyesore running down the side of the building and also air is not a very good conductor of heat. How big is the collector going to be that is going to be heated mounted on the roof.
I’ve never heard of this sort of solar heating before using air as the conduction medium it seems to me it is going to be bulky and very inefficient. Also it only works when the sun is shining, not exactly the time that you really want space heating.
