Changing over to solar electricity water heating takes some research to be sure the right water heating unit is being installed for the climate in which the individual lives. The bulk of the solar energy water heating units are engineered to work best in climates where is doesn't fall to freezing temperatures much, if any, in the course of the year. The cause of the reason is because the water in the pipes of the system will freeze and damage the system, as the sun's rays aren't enough in freezing temperatures to keep it moving through the pipes without freezing. These solar energy water heating systems are efficient way of heating the water supply for a home or for commercial use, and also can be employed for solar pool heating, so saving costs and the environment.
Types of Materials and Systems
One piece of gear that all solar energy water heating systems need is the solar collector which enhances the sun's rays and converts them to energy. There are 3 differing types of solar collectors on the market today. The 1st is the flat plate collector that has a glaze on it and is insulated. They contain a plate that is intended to soak up the sun's rays and lies underneath at least one cover plate, which is customarily made from either plastic or glass, though with pool plates they're regularly made from metal. Another sort of collector in solar energy water heating is the integral collector or batch system. In this system the water passes thru the tubes that are contained in an insulated, glazed box which collects the daylight and preheats the water. The 3rd system uses abandoned tube solar collectors, and is generally only employed in commercial settings.
There are 2 basic kinds of systems in solar energy water heating : active and passive. The active systems have a kind of pump that moves the water or the antifreeze thru the pipes in order that it can be heated by the collection plates. The passive systems hold the water in a collection container where the solar cells are so it can be heated and then move by way of the hot water rising to the top, into the storage tank. Each system has it's benefits, with the active systems being better at heating the water and the passive systems usually lasting longer and being more trustworthy.
Both systems use a backup heater in the storage tank so that it can be used when there are a series of cloudy days outside and the water cannot be heated by the sun.
