Solar Water Heating System

Evacuated Tubes

The heat from the copper pipe is transferred into the Header Pipe through which more antifreeze flows. This heated antifreeze is then pumped through the hot water tank where the water gets hotter and the antifreeze gets cooler. The antifreeze then returns to the solar heating module to be heated again. This flow is constant resulting in the water in the tank becoming hot.

This incredibly simple system is a sealed system, which means that minimal maintenance is required over its life. Individual tubes can be simply replaced should the need arise. The system can easily heat water to 90 degrees on hot days, and even at very cold temperatures or when there is no sunlight will contribute to the heating of the water up to around 50 degrees, from which point the standard heating system will top up the requirements.

Flat Panel Solar Water Heating

A Flat-plate collector is typically made from a metal box which has a glass or plastic cover on top. The cover is known as the glaze, and there is an absorber plate on the bottom. The sides and bottom of the collector are usually insulated to minimize heat loss.

Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. Liquid which passes through the pipes is heated and these pipes are attached to the absorber plate. Absorber plates are usually painted with special coatings which absorb and retain heat better than standard black paint. Absorber plates are usually made of copper or aluminium pipes as these are good heat conductors. Copper is more expensive, but is a better conductor and less prone to corrosion than Aluminium.

Performance Guarantee:  20 years
Certificate: CE,UL,(IEC, EN12975 is available)

Solar Water Heating Systems

Solar thermal systems take energy from the sun and convert it to useful heat to provide hot water. Solar thermal systems basically consist of three main components:

• Solar Collector Modules: evacuated tubes collect heat through infra red radiation and transfer it to the fluid in the solar circuit pipes that flow through them.
• Solar Circuit: the solar circuit is controlled by a computer which drives a pump, the solar circuit transports the hot fluid from the collectors to the hot water cylinder.
• Unvented Cylinder: A twin coil cylinder is generally required. The hot fluid from the solar circuit enters the hot water cylinder through a heat exchange coil just as any domestic system, where necessary the second coil – that of gas or oil or electricity – will top up the hot water requirements.

Can I use a solar system with a combi boiler?
 
The simple answer is yes, however you will need a qualified plumber. You can incorporate a standard solar system, which means you will need to install a single coiled UNVENTED cylinder (or tank) to store your hot water in. The hot water, when called upon, comes directly from your hot water tank to your tap. However, if the hot water is not at a sufficient temperature, it is diverted by a thermostatic valve up to your combi boiler to be taken up to full temperature. You will need to check that your combi boiler will take PRE HEATED water. If not it may be possible to install a mixer valve to still allow you to install a solar system without changing your boiler.
