solar thermal solution will provide a typical household with
50 to 60% of their Domestic Hot Water in a year. In the sumer
this will be as high as 100% meaning that the boiler will
never have to be fired up, therefeore saving money and energy.
In the winter the boiler will be required to help heat the
domestic hot water a little more due to the lower level of
energy produced by the sun.
People tend to think that a solar solution can only work
if the sun is shining, but this is not the case as Solar Thermal
Systems work with diffused radiation, so if it's cloudy, no
problem, a good level of the suns energy can still be obtained
to heat your hot water.

When carring out our installations for Solar Energy Systems
we tend to use Glow-worm as a preferred supplier. We find
their Clearly Solar Panels have a good surface area for collecting
the energy, are very robust and are one of the lightest flat
panels on the market.
HOW DOES IT WORK?
1. The panels collect energy from the sun which heats the
fluid in the solar panel.
2. †When the fluid in the panels is hot enough, the pump station
circulates the hot fluid around the system.
3. 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.
4. †If the temperature sensor in the cylinder detects that
the solar panel hasnít collected enough energy to heat the
hot water to the required temperature, thatís 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.
5. 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. †
