Solar Heat

Solar heat collection and transmission via air (not liquid).

These units look nice. Add a solar panel to run the fan and optionally a good filter to clean the air.

Cansolair Inc. has developed a forced convection solar heating unit called the Model RA 240 SOLAR MAX. A dwelling of 1000 square feet can have a complete air change in 1.5 hours. Working experience indicates that comfortable room temperature can be maintained in a 1000 square foot dwelling with 15 minutes of sunlight per hour.

CSA Approved Maintenance Free Thermostatically Controlled Forced Convection Filtered Air Environmentally Friendly Heat Energy. 240 aluminum cans comprise the core of each Model RA 240 SOLAR MAX.

Ninety cubic feet per minute of colder and relatively heavier air is drawn by a quiet and powerfull fan through a filter from near the floor.

This filtered air is pumped through the first checkvalve, the specially modified collector core, and then back into your living space through the last check valve near the ceiling. The resulting high volume air movement not only filters, but will destratify as well as directly heat the air in your home or business. One or more modules can be vertically or horizontally mounted on any South-East, South, or South-West-facing wall or roof that is free from shadow.

Each fully automatic, thermostatically controlled module can maintain average room temperature in about eight thousand cubic feet of residential or commercial space.
