Solar Air Heating

One of the inescapable realities of doing business in Canada is the cost of heating. Long, cold winters mean that for a good part of the year, Canadian businesses have to spend money to heat air brought into the workplace. That directly affects the bottom line.

A simple technology can dramatically reduce fuel consumption and heating costs, particularly for buildings with a high demand for fresh air. The concept: use solar energy to preheat outside air before it is introduced into a plant or other facility. The warmed air can be distributed as is, further heated in a building's primary heating system or used as combustion air for industrial furnaces.

Facilities that could benefit from this technology include warehouses, large institutions such as hospital and schools, industrial plants, garages, even apartment buildings.
