How can I choose the best solar water heater?

solar water heaters can be money saver and are environmentally friendly, but the initial purchase may be expensive. When buying the solar water heater, it is important to look at different types of solar water heaters to determine which type would best work in a particular house. The solar water heater can save the household anywhere from 50 - 80 percent of the current fuel cost of water heating, so the choice will help maximize these savings. Although solar systems are available for all climate, different regions will benefit from different types of heating. The solar water heater is active or passive. The active solar water heater uses circulation pumps and controls and passive heating no. This means that the active solar water heater requires electricity and the passive system does not. Passive solar water heaters are best used only in warm climate.

Active Sun Watermen are either indirect or direct circulation systems. Direct circulation systems work in subneEBI, which rarely freeze but colder climate will require an indirect circulation system. Both types use collectors to take energy from the sun to warm up water. Indirect circulation systems use heat transfer fluid that circulates through collectors. This fluid collects heat and then transmits it to the water used in the household. Direct systems circulate water to be used through collectors.

There are two types of passive solar hot water systems. The first is the integral system of enforcement of collectors in which the storage tank acts as a collector. These are generally painted black. The sun directly warms up water, then the water pressure from the well or urban water is pushing heated water on faucets or another holding tank in the house. The second is the thermosyphna of the system in which the storage tank is mounted above the collector and gravity is pushing the heated water through the tank, but they mustto be mounted on the roof and are therefore not suitable for all houses.

So when choosing a solar water heater, it should first be determined which type is suitable for the climate in which it will be installed. Next, determine the amount of solar energy available. This will help determine sun effectiveness. The amount of hot water required must also be noted. This determines the size and type of collector and storage tanks. Finally, check the prices and consider all other factors to determine the greatest savings and the most effective solar water heater for location, size and use of the house.
