Solar Thermal Hot Water
Anglia Renewable Energy uses top of the range solar panels collectors that are suitable for both domestic and commercial applications. The efficiency of these units is such that just one solar collector is adequate for an average household (3-4 people). The system is modular, so you can add more collectors if required. It also conforms to the solar keymark and British Standards BS EN 12975.
A solar thermal solution will provide a typical UK household with 80% of their Domestic Hot Water in a year. In the summertime this will be as high as 100% meaning that the boiler will never have to fire up saving both energy and money. In the winter a lower level of energy is produced by the sun, so a boiler is also needed to provide energy to heat the domestic hot water.
It’s a common misconception that solar thermal systems only work when the sun is shining. Solar thermal systems work with diffused radiation, so even on a cloudy day you will still get a good level of energy from the sun to heat your hot water.
- The panels collect energy from the sun which heats the fluid in the solar panel.
- When the fluid in the panels is hot enough, the pump station circulates the hot fluid around the system.
- The hot fluid is pumped around the coil at the bottom of the twin coil cylinder and heats the potable (or mains) water held within the cylinder for domestic use.
- If the temperature sensor in the cylinder detects that the solar panel hasn’t collected enough energy to heat the hot water to the required temperature, that’s when the boiler will fire up, heat the top coil of the cylinder and top up the temperature of the hot water so that it comes out of your taps at the temperature needed.
- The solar controller is the brains of the operation, managing the solar system during daylight hours, enabling you to time your hot water, just like a heating programmer, and measure the amount of energy you have gained from the sun.
