Solar Hot Air System

A Solar Hot Air (SHA) system is the most economical way to capture the sun’s energy to help heat rooms or areas in your home or business. Small 1 or 2 panel systems are ideal for large rooms or entire levels in a house. Larger systems of 4 panels or more can be used to heat large homes or for use in a commercial or industrial applications.

A SHA system consists of three main parts; panels, ducting and fan. There is also a Photovoltaic (PV) panel for a power supply and thermostat. The operation of a SHA is very simple. The PV panel supplies power to the fan via a temperature sensor. When there is sufficient heat in the panels, the fan will start. The fan draws the cool air in from the lower inlet and pushes it into the panel. As the air moves through the panel it is warmed - up to 40 C. Warm air is pushed out of the outlet at the top of the panel and back into the room or area it was taken from. Additional ducting can be install to move the warm air to another room or area. There is no mixing with the outside air. A thermostat is used to keep the system from overheating the area involved or to keep the system off in the summer.

Nova Sun Power installed two Fujitsu heat pumps and a solar hot water system for me in 2010.  Rob MacKean was extremely helpful. But more importantly, he is very resourceful and was able to find unobtrusive ways to install which is hugely important in an old house such as mine. Since the installation he has also helped with various upkeep needs. I recommend this company highly.
