Solar water heating (SWH) also called solar hot water (SHW) systems consist of various innovative and trusted renewable energy technologies which have been used for many, many years. Solar water heating is highly popular in countries including China, Australia, Turkey, Greece, Israel, Austria, and Japan.
There are two types of solar water heating systems:
The’close-coupled’ system – in which the storage tank is mounted above the solar collectors on the roof of a structure and because the hot water rises naturally in the tank by means of a thermosiphon flow there’s absolutely not any need for a pump.
Along with the pump-circulated’ system – in which the storage tank is mounted to the floor or floor and is under the solar collectors, a pump circulates heat or water fluid between the tank and collectors.
If you want to buy a solar hot water system then you can see on online websites.
Solar water heating systems are invented to create hot water throughout the year. But during the winter months, there may be inadequate sunlight to produce the necessary quantity of hot water.
The water that’s heated by sunlight is used in many different ways. Although the best-known methods are for the supply of a domestic water supply, solar water heating is also put to work in an industrial setting, i.e. to create electricity.
Systems suitable for very hot climates can be assembled in a much easier and more economical way, and are regarded as a suitable technology for such areas. The solar water heating market is dominated by India, China, Japan, and Europe.
