How we achieve 70% Hot Water Heating

Solargreenpower Mains pressure Hot Water Cylinders are manufactured in the UK to the highest quality standards in stainless steel, Factory insulated, and available in a range of sizes.

Because of their unique design the CH & Solar coils are positioned to achieve maximum solar collection performance with minimum energy consumption in CH or Immersion top up heating mode.

The most common cylinder size in the average household is 122L (25Gallon).

We recommend the largest Cylinder you can accommodate, 200 litres is good, 300 is much better. Mains Pressure cylinders mean no tanks in the roof and "Powerful Hot Water Showers"

New Solar Cylinder pre-heats all hot water even on cloudy days via the bottom solar coil.

CH Boiler or Immersion heater only heats the same amount of water, but not by as much – On sunny days not at all!

"Because Solar Heat is Free!"

Heat Pumps Ground & Air Source - Up to 400% efficient

A heat pump extracts the heat from solar energy stored in the ground or in the air and concentrates it for use in a domestic heating system.It acts like a fridge in reverse. Conventional refrigeration tecnology absorbs the heat from the ground or air into a refrigerant, which is then compressed to raise its temperature. A heat exchanger then takes out the heat and uses it in the heating system to provide warmth and hot water. Domestiv heat pumps have been used in Europe for many years where they are a tried and tested form of high efficiency low cost heating.

Both ground source and air source heat pumps offer energy and efficiency, reduced carbon emissions and lower running costs. Your choice of system will depend on your budget and on the type of application best suited to your needs and your home.

Heat pump cycle

Benefits of ground source:

  • Higher efficiency because it has a constant temperature energy source – the ground
  • Smaller sized units for internal or external installation
  • Ideal for multiple installtions with vertical boreholes (reduced drilling costs)

Benefits of air source:

  • Lower capital cost and operational to -15°C
  • Reverse curcle defrost only 4 minutes per hour
  • Ideal for multi-storey apartment buildings
  • For stand-alone use (monovalent) or integration with existing heating systems (bivalent)

Evacuated Tube Collectors

Evacuated Tube CollectorsThese consist of metal (copper) heat pipes, to which is attached a black copper absorber plate, inside a vacuum-sealed solar tube. The heat pipe is hollow and the space inside, like that of the solar tube, is evacuated. The reason for evacuating the heat pipe, however, is not insulation but to promote a change of state of the liquid it contains. Inside the heat pipe is a small quantity of liquid, such as alcohol or purified water plus special additives. The vacuum enables the liquid to boil (i.e. turn from liquid to vapour) at a much lower temperature than it would at normal atmospheric pressure. When solar radiation falls the surface of the absorber, the liquid within the heat tube quickly turns to hot vapour rises to the top of the pipe. Water, or glycol, flows through a manifold and picks up the heat, while the fluid in the heat pipe condenses and flows back down the tube for the process to be repeated.

An advantage of heat pipes over direct-flow evacuated-tubes is the "dry" connection between the absorber and the header, which makes installation easier and also means that individual tubes can be exchanged without emptying the entire system of its fluid.
