I don't throw away cans from soda: I tell you why I need them
It just so happened that this fall most of my articles on Zen are devoted to the topic of economical heating of a country house. And this one is no exception.
I collect aluminum beverage cans for use in a solar heating system. I am planning to assemble the simplest solar air collector with my own hands.
And the central part of the solar collector - absorber - will be made of "bamboo" aluminum cans.
As planned, it will look something like this:
solar collector - will become mine additional autonomous home heating system. I emphasize, additional, not basic.
I will briefly tell you how it works:
- a box is assembled from moisture-resistant plywood with dimensions of 1000 * 1000 * 400 mm. The walls of the box are sheathed with foil-clad insulation.
- "Bamboos" made of aluminum cans glued with sealant are inserted into the central part. Bamboos are painted matt black with automotive paint;
- Holes for plastic air ducts are drilled in two ends of the system with a crown and 1 channel fan is installed.
- The construction is closed with monolithic polycarbonate or K-glass.
We expose the solar collector at an optimal angle to the sun and connect the duct fan with a thermal relay. On the relay, we set the switch-on temperature at 75 degrees, off at 50 degrees. We stretch the air duct into the house.
Done: on a sunny day (about 12-14 days per winter), the house will automatically (thanks to the relay) warm air flow (about 60-65 degrees at the entrance to the house).
This will result in energy savings for heating. Taking into account the cost of materials (about 4000 rubles), the system will pay off in 2 years - I will "heat up" the sun both in winter and in the off-season.
