Solar Window Heater

Those who need more heat in their homes or only in some rooms should know that an eco-friendly device has been invented for helping them in this matter. Some people have one or two rooms facing south but they still feel chilly inside them. This can happen if that room has a small window that does not allow sufficient sun light to come in and warm the room.

The eco-friendly device we mentioned previously uses the sun for warming the chilly rooms. This device can only be installed in the rooms that are facing south as they can work only by using the sunlight as a source of energy. This device is known as a solar window heater. Its size is can vary from window to window and it is framed in clear pine for paining. You might imagine this device as a box that has a panel made from aluminum (this is the collector) behind a sheet of thin wood on the inside and a sheet of air tight Plexiglas on the outside, so that it can trap the collected heat. Inside the box there can be found two baffles that are made to look like a maze. This will allow the air to be heated continuously as it goes inside the box through the fan.

You should know that the aluminum collector panel has to be finished in flat black so that the sun absorption is made at maximum capacity. During the sunny days the panel can reach temperatures of 140 or even 170 degrees. Nowadays you can find on the market a new solar window heater model made from copper instead of aluminum. This solar window heater is also finished in flat black for the same previous reasons we mentioned.

Inside the panel there usually is a thermostat switch. In the sunny days when the temperature raises a lot if the temperature of the heated air reaches 120 degrees then the thermostat switch will automatically turn the fan on. In the moment the heated air reaches the temperature of 90 degrees then the fan will be turned automatically off.
