Many people in the UK believe that solar energy will only work when the sun shines and therefore solar power is unsuitable in the British climate - but this is not the case.

A result of years of continuous development the Pure Energy Solutions system now performs even on cloudy days. The Pure Energy Solutions system makes solar energy affordable for the home and is attracting much interest from private homeowners, local authorities and housing associations.

In hundreds of installations the Pure Energy Solutions system provides 90% to 100% of hot water in the summer and around 75% throughout the year.

Solar energy availability in the UK is much greater than most people imagine. The UK receives on average approximately 65% of the annual radiation experienced by the South of Spain. The solar energy that we experience is accounted for by approximately 40% direct radiation (received when it is sunny) and some 60% diffused, or scattered, radiation (received on cloudy days). The Pure Energy Solutions system is an economical and virtually maintenance free way to harness this valuable and free supply of renewable energy. Through the advances in the design and performance of the Pure Energy Solutions water heaters we can now capture more of that energy.

Finally by choosing Pure Energy Solutions system as part of your energy efficient heating system you are guaranteed to save fuel, you will achieve valuable reductions in C02 emissions, and as more and more of make use of this free source of natural energy, our exposure and that of future generations to climate change and dangerous technologies such as nuclear power will be reduced.

How it works

The absorber plate, when it collects light, causes an electro-magnetic stimulation of particles in the absorber plate. This causes light energy to be transferred to the copper tubes behind the absorber plate by conduction and then, by the same process, into the heat transfer fluid comprising a closed circuit inside the copper tubes. From there, the heat will be pumped as required into a hot water cylinder and/or a heat sink for a central heating system.

The system is controlled by a digital electronic controller, which can be programmed by the installer for maximum efficiency for each particular installation.

We recommend the use of a Pure Energy Solutions ZPS Pump and Control Set, or a standard circulating pump fitted with isolating valves, should be incorporated within the pipework.

CylindersChoice of cylinder is one of the most important judgements that a solar engineer must make. For households with 4 or more occupants, Pure Energy Solutions recommend a 200-400 litre cylinder containing a heat transfer coil for solar and other heat transfer coils (for use with a gas boiler and/or an electric element). Where there are two coils, the bottom or lower coil should be used for solar heat transfer. Where a pre-heat cylinder is used it should be of sufficient size to exceed about 80% of the average daily hot water usage.

The indirect coils are designed to heat the whole of the cylinders contents and sit very low in the base of the unit (unlike conventional coils). Add to the this the coils large surface area, a very fast recovery is achieved on 100% of its volume. High heat retention is then achieved by use of 50mm thick CFC/HCFC Free (ODP Zero) lagging.

A pocket to accommodate the solar sensor is also provided.

The cylinder carries a 25 year manufacturer's warranty.
