Solar Thermal

Solar %20ThermalBy heating your water using the sun's radiation, thermal collectors can provide almost all your hot water during the summer and an average of 50 - 70% annually. Put simply, a solar fluid circulates through the panels and into a twin coil solar cylinder, which in turn heats the water in the central heating system.

A twin coil cylinder comprises one coil which receives the heat from the collector on the roof, and another that is used to supply heat from the main household heat source/boiler when solar energy is insufficient. Some are also fitted with an immersion heater.

A typical family of four will use between 200 and 300 litres of water per day.

There are two types of collectors - a flat plate or an evacuated tube. Price and efficiency need to be evaluated. An evacuated system is generally more expensive but more efficient.

You'll need to ensure that energy saving measures have been taken around the home (i.e. roof insulation/cavity wall insulation, double glazing).

Design and location considerations...

Although typically used domestically, there are solar thermal systems on the market to cater for any size of building. Ideally they will need to be mounted on a south facing surface, which receives south/south-east sunlight for most of the day. Since twin coil cylinders are usually quite large, space and location need to be considered.

The sizing of the total system needs to be calculated.
