Solar Hot Water System How It Works

An indirect system would use a working fluid consisting of water and anti freeze and possibly corrosion inhibitors.

Solar hot water system how it works.

Both high efficiency and tankless water heaters can cut back on energy use. Hot water rises so the heated water moves to the top of the tank. Here s a simple summary of how rooftop solar hot water panels work. Solar hot water systems either heat the water to be used direct or heat a working fluid and transfer the heat via a heat exchanger to the water indirect.

The solar panel absorbs the sun s heat and passes it on to the water as it circulates. A solar water heater is typically used in conjunction with a traditional heater since weather affects solar hot water production. The water leaving the collector is hotter than the water entering it and carries its heat toward your hot water tank. There are two types of collectors in solar hot water services.

How solar hot water works on your home when the sun shines collectors on the roof convert the energy in solar radiation to heat the water. But solar is on another level. In both direct and indirect systems water in the solar storage tank flows through a roof mounted solar panel. The water is pumped to the bottom of the storage tank.

The hot water moves to a hot water storage tank. Solar water heaters are typically described according to the type of collector and the circulation system. Flat plate collectors suitable where tank roof mounting is necessary. As the hot water comes in it pushes colder water to the bottom of the tank because hot water rises so cold water must drop where its only option is to go back into the solar panel to get hotter.

In the simplest panels sun heats water flowing in a circuit through the collector the panel on your roof. How it works solar water heaters solar water heaters come in a wide variety of designs all including a collector and storage tank and all using the sun s thermal energy to heat water. Our solar hot water heater systems are automatically controlled to maintain optimum temperatures.
