This new solar air heater hangs in your window, generating heat equivalent to a 500-watt electric heater, depending on the daytime sun and cloud cover. It is portable at only 26 lbs. in weight and can easily be moved.
  The solar heated collector measures 48 in. long, 24 in. wide, and 2.5 in. thick and features a built-in solar-powered fan that moves the heated air into the room. You simply hang or set the collector against the inside of a south-facing window, the fan draws indoor air up and through the aluminum collector coils heated by the sun and then recirculates the warmed air up and back into the room. The fan also features a speed control which adjusts the air temperature. This unit also features a 20-watt PV panel for performance in low light and cloudy conditions.
  “It’s designed for interior installation behind a window; double pane, low-E, Argon and triple pane windows will reduce the efficiency to less than 40 to 65 percent. For optimum efficiency it is best used in spaces that are 150 sq. ft. or smaller and we have seen it used successfully in homes, chicken coops, workshops, backyard greenhouses, and anywhere else there are unobstructed southern-facing windows,” says Cam Mackay, president of Solar Infra Systems, Surrey, B.C. The solar air heating unit is available from Northern Tool & Equipment, Mid States Distributing, and retails for $475 at www.solarinfrasystems.com.
  The company also designs and sells large wall, mounted solar air heaters designed for commercial businesses such as barns, chicken hatcheries, greenhouses, cattle barns, and warehouses.
  “We are reducing the natural gas or propane used to heat a greenhouse. We can save a 100,000 sq. ft. greenhouse up to $140,000 per year compared to using natural gas,” says Mackay.
