Direct Solar Water Heater System

Instead these high efficiency appliances use dedicated solar collectors on your rooftop to draw power from the sun.

Direct solar water heater system.

Most solar water heaters require a well insulated storage tank. Because the array completely drains water can be used in the solar loop which avoids the need for double wall heat exchangers demanded in some localities. In this system potable water is drawn directly from the storage tank and circulated through the array to be heated and returned to a recirculation port in the tank. Instead of relying on glycol for freeze protection this system allows all the water in the array to drain back from the array and into a storage vessel in the solar loop when the pump is turned off.

Two types of solar water heating systems are available. The mechanicals for this type of system is almost identical to a boiler application except that the solar array is the heat source. The solar water heater is a device that uses solar energy to generate heat not electricity that can be used to heat water for bathing heating spaces industrial processes or even solar cooling. In two tank systems the solar water heater preheats water before it enters the conventional water heater.

Solar water heaters require direct sunlight to function. Direct solar water heating system there are two main types of water heating system direct and indirect. Solar storage tanks have an additional outlet and inlet connected to and from the collector. Indirect or closed loop systems in which potable water is heated indirectly by a heat transfer fluid that is heated in the collector and passes through a heat exchanger to transfer its heat to the domestic or service water.

In an indirect system fluid such as anti freeze is heated and then passed through a heat exchanger fitted to the water tank. The direct open loop solar water system freeze recirculation is both the simplest and most efficient type of solar heating system. Annual maintenance is recommended to check the pump and antifreeze. Solar heaters are fully powered by solar energy.

The system does not function on cloudy rainy or foggy days. Unlike traditional water heaters solar water heaters don t use energy from the grid to heat water. Over 350 solar and environmentally responsible products solar direct s on line source for solar panels solar installations and more. This means that power cuts and power cuts have no effect on their function.

In one tank systems the back up heater is combined with the solar storage in one tank. Solar heaters require sufficient roof space to accommodate them.
