DIY Solar Water Heater
A very efficient method of heating water for houses is by using the solar hot water heater, which is also friendly to the environment. A solar water heating system uses thermal collectors to capture the energy of the sun and then transfers any heat to the water using the fluid system. It may take a small bit of electricity to help pump this fluid to the reservoir or the tank, that is for heat storage so it have be used later.
The systems can efficiently heat the water to be used in many areas of a house, business, or industry. Radiant-floor heating and heating swimming-pool water are the most used ways for the solar hot water heaters.
As far as home water heating, you can choose from two kinds of systems. One is the compact system and the other one is the pumped system. Normally either one uses an extra energy source, that could be an electric element for heating or possible the basic central system for heating with gas or fuel oil, and these are activated only as the water held in the reservoir cools down under 50 degrees centigrade. Having this setup will guarantee you a steady supply of hot water. You could go as far as to combine the solar heating of the water with the wood-burning stoves, which will work well in cooler climates and not utilize any fossil fuels or electricity.
The collectors normally are installed on a building, house roof, or a wall facing the sun. On rare occasions the collectors stand alone. The systems that are passive drives its fluid to the collector and through it, the system that is active pumps its fluid through the system.
The collector can be made of a box that is insulated and topped off with a top that is glass. Then the solar collector has a flat shape and is made of copper piping, which are painted black and then connected to either sheet metal or tubes of metal, which are enclosed in a glass cylinder. At times the parabolic mirror focuses all the energy from the sun on that tube. Many of these systems totally covert the sun’s light into heat and have no dependence upon an outside temperature.
The solar water heater is not just financially friendly, but also environmentally friendly too. In climates that are basically warm your backup source of energy will be utilized minimally and even in the climates that are cool in nature the amount of backup you will use is much less that the regular system for heating water.
