Solar Air Heater for Commercial or Home Heating

Solar air heater systems use the solar radiations to heat a particular room using solar panels. There are many ways of using solar air heating, and we can even build one at home using help from online sources. It is a type of solar thermal system, where air is heated in a collector by the sun's radiation and either transferred directly to the interior space or to a storage medium such as a rock bin.

Solar panels are used to operate such systems. The solar panels heat the air which is then conveyed into a room. The basic component of this system includes solar collector panels, a duct system and diffusers. The heated air can operate with or without a fan. Without the fan the air is distributed by the action of a natural ventilation system.

In agriculture, the food produced sometimes needs to be kept in warm places especially during the monsoons. The solar air heater works here. It can raise the temperature of the room so that it is appropriately heated. In this way the products can stay safe and will not get spoiled because of the humidity.

The solar air heater works in much the same way as a solar water heater works. The heater is place outside the room in the open so that it can catch the sunlight. It is generally made up of solar panels but people use a variety of things. Some use aluminum drink cans and paint them black. Then they are arranged on a board and fit to a frame. The panels or the cans should have holes in them connecting each other so that the air travels through them. Hence the cold air from the room moves through the cans and the warm air enters into the room causing raise in temperature. In this way a solar air heater is a very economical way to heat a room. Rather than using expensive heating devices that require a lot of electricity it is definitely a cost-effective solution.
