Solar Hot Water System How It Works

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.

Solar hot water system how it works.

Flat plate collectors suitable where tank roof mounting is necessary. In both direct and indirect systems water in the solar storage tank flows through a roof mounted solar panel. 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.

How solar hot water works aside from cost and greenhouse gas emissions savings the beauty of a solar hot water system is its relative simplicity and durability. 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. It s about as green as hot water can get. The hot water moves to a hot water storage tank.

Solar water heating systems work by capturing sunlight and using it to provide a significant proportion of your annual hot water demands. There are two types of collectors in solar hot water services. Hot water rises so the heated water moves to the top of the tank. An indirect system would use a working fluid consisting of water and anti freeze and possibly corrosion inhibitors.

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. Here s a simple summary of how rooftop solar hot water panels work. In the simplest panels sun heats water flowing in a circuit through the collector the panel on your roof. Our solar hot water heater systems are automatically controlled to maintain optimum temperatures.

The water is pumped to the bottom of the storage tank. But solar is on another level. The water leaving the collector is hotter than the water entering it and carries its heat toward your hot water tank.
