Solar power has many uses and while most people think of it as a great way to produce electricity, it can also be used to heat the water in your home. A solar water heater utilizes the thermal component found in sunlight and can heat all the water your home typically needs with only simple sunlight for fuel. A solar water heater is simple to install and a very inexpensive way to cut your monthly power bills.

Solar hot water systems only contain a few components and can be installed on your home in an afternoon. The key part in the system is the solar collector and this is regularly mounted on a southern-facing roof. The solar collector looks very similar to a solar panel used in a normal solar power system, but is basically different in every other way. A meshing of of thin pipes are mounted in the solar collector’s weatherproof enclosure. These thin pipes are all connected to an entry and exit plumbing fixture and will channel any water passing through the collector into this webbing. During the day these thin pipes become very hot when exposed to sunlight and can rapidly heat up any water that is passing through them. You can use this thermal collector to heat the water you use for bathing and cooking by linking this solar collector to your home’s hot water system. The best part is this system can be very passive and will use the water pressure in your home to circulate the water through the collector naturally.

A slightly more sophisticated solar water heater is used in colder climates or on larger homes that require more significant quantities of hot water. These varieties of solar hot water systems use a small circulating pump to force a specialized liquid through the solar collector and back down into a thermal holding tank. This circulation system is a closed loop and the same liquid makes the round trip through the collector several times each day. The home’s hot water plumbing is also passed through this thermal storage tank and as it sits in the reservoir, it is warmed by the hot solar plumbing. The home’s water never makes contact wth the liquid passing through the solar water heater; it is simply heated through contact with the pipes.

The benefit of this type of system is that it can be used in colder climates where water would freeze if it were passed through the solar collector directly in the winter months. By using this specialized liquid you can enjoy all the benefits of a solar water heater without the danger of freezing. By using a thermal storage tank you will always have the other benefit of a good source of hot water for use. This allows you to enjoy the benefits of a solar water heater through the evenings when the sun is no longer able to heat the water.

These classes of systems have also been adapted for heating the water in pools. In this class of system the solar collector is linked to the circulatory system for the pool’s water and heats it with the sun. This offers a very cost-effective way to keep your pool at a comfortable temperature for swimming without spending any money on fuel.
