What is a Solar Heater? We all know, But What are its functions? Lets Get On To Read Them!
A Solar Heater is a device that absorbs sunlight to heat water. It is quite economical to use it for baths or showers for the entire family if the number is large.
A Solar Heater also enables substantial energy savings as solar power as well as it also plays a vital role in heating water for sanitary use throughout the year.
Supplying a washing machine or dishwasher with this hot water also cuts out the electricity used by these appliances to heat the water and shortens the washing cycles, as long as certain precautionary measures are taken.
How Does A Solar Heater Work?
? Sunlight is absorbed by the solar panel
? The heat transfers to the water tank
? When there is insufficient sunlight, the water is preheated and a back-up system tajes over to bring the water to the required temperature. This system can, therefore, be used at a constant temperature throughout the year.
Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't. There are two types of active solar water heating systems:
Direct Circulation Systems
Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.
Indirect circulation systems
Indirect Circulation Systems
Pumps circulate a non-freezing, heat-transfer fluid through the collectors and a heat exchanger. This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.
Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.
