Solar Water Heating

Green Stamp Ltd are proud to be chosen as distributors of the latest in solar hot water heating. Solar storage is a revolution in home solar powered hot water systems.

Price only £1495 inc. VAT (Inclusive of fitting)

The low cost Solar Array is a new invention that heats and stores a small volume of water to pre-heat the water entering either a combi boiler or storage cylinder.
As the water is preheated the boiler reduces its gas consumption thereby reducing green house gases and saving on gas usage. Summer and Winter this Solar System simply and effectively works by raising the temperature of the water that sits in a small holding tank so that your boiler uses less energy to heat the water before it reaches your tap.

The zero carbon solar panel water heating system which is reliable, quickly fitted and surprisingly affordable, giving you the satisfaction of knowing that your solar hot water is produced environmentally.

How does it work?

  • Cold water normally enters the boiler at 20 degrees or lower in the winter and the boiler has to heat it up to 55 degrees approx.
  • With the water being preheated the boiler does not have to burn as much gas to reach the 55 degrees.
  • Initial tests have shown that the gas is reduced by 25% when the water is being drawn from the solar storage tank and has been preheated.
  • Tests have also shown that it is feasible to shut the boiler off during the day in good weather.

LOCATION

For the maximum heat absorption a South facing aspect with an angle of
10 degrees is ideal.

However, the design of the unit is not to generate a vast amount of hot water
within the array but small quantities (2 litres) to help lift the
cold water temperature going into the boiler or water system.

In this respect the collector can be mounted in any aspect or wall-
mounted as it will collect solar and ambient heat and then distribute
it to the tank if there is a difference between the tank temperature
and the collector temperature.
