..in the winter it can be cruddy coming home from work to 12c. It takes a couple of hours to get the temperature up higher so I am building my own passive solar heater..or active if I add a solar panel and fan..passive to start. I read an article on instructables.com about it..it seemed easy ro make and I have most of the material on-site.
This early stage is fairly easy. Remove the tab, flip it over and drill a 1 inch hole in the bottom of the can below the mouth hole on the top.
Repeat this for around 3 more cans and by my estimation you should have enough heat from the sun to heat the house during the winter…my estimation on the number of cans might be off by 300 or so..unless my house was on Mercury.
The basic idea is the air will be drawn into these cans which will be painted black and stacked and caulked together. They will be side by side sort of like the last picture and housed inside a sealed windowed chamber..so the cans are hot and draw air up the cans and into the house..starts lower and rises. I have until October but I wanted to get started while A* is away since I cannot get rollin on the floorin until she gets back…that and fixing the shed. Boo winter…booooo snow….
Yes, someone I know drinks too much Diet Pepsi. Nobody will be complaining about how much diet pepsi I drink when it’s hot in the house in the winter (and my heart is beating 200 bpm thanks to diet pepsi..you should see my mexican hatdance when my heart is pumping like that. Impressive)!
