solar panel heater
I recently discovered an inexpensive and environmentally friendly product to supplement your home heating system. It is a compact room heater, but efficient, solar designed to be installed on the south facing rooms of your house or apartment.
Since it is powered by the sun, and heated with hot air, the only mechanical or moving parts is a simple fan that draws air temperature in the heating panel through a series of canals heating, exhaust pipes and the air is heated again in the room.
The window solar heater core is 20 "x 32" x 3.5 " framing clear pine for painting or staining. Think of it as a box with an aluminum panel (collector) behind a sheet of air tight Plexiglas on the outside, and a sheet of thin wood on the inside to trap the collected heat.
Inside the box are two baffles configured to resemble a maze. This allows a continuous flow air is heated as it is drawn through the fan box.
The aluminum collector panel has a matte black finish to maximize the absorption the heat of the sun. On a day of sunshine, the panel will reach temperatures of 140 – 170 degrees.
A new version of the solar heater window pane replaced High quality aluminum copper, also finished in matte black.
Located inside the panel is a thermostat switch. When the temperature of hot air that comes 120 degrees, the switch automatically turns the fan. When the air temperature cools to 90 degrees or less, the fan turns itself off.
The small efficient fan will move 102 meters cubic of air per minute, or about 6,000 cubic meters per hour. The cost of electricity to run the fan is about $ 3.00 per year.
The basic model sells for around $ 150.00. The newer, copper lined solar window heater sells additional $ 10.
The electrical components are available separately for $ 42.95. These include the fan, thermostat, control box output and transformer. If you're handy, you could probably build your own solar heater for the window of around $ 80.
