Solar Water Heating

We specialise in thermal collection for domestic hot water use

Thermal Collection – Collectors are 85 to 95% efficient

Transfer radiant heat from the sun into water ready for domestic hot water heating. The hot water cylinder stores the heated water until you need it. You can save up to 70% of your water heating bills, about 40% in winter and maybe 100% in summer.

Photovoltaic Collection - Collectors are 23 to 24% efficient

Radiant heat from the sun is converted to electricity. This can be used to power any electrical appliance, but currently must be used when generated. If there is no requirement from the house for electricity, it may be "sold" to a power company.

Solar Collectors / Solar Collection Panels

There are different grades of solar collector to choose from: standard, marine grade and then the premium grade. We can help you select the grade to suit your location. (Note – There is little difference between the efficiency of flat plate and evacuated tube collectors in a domestic situation.)

Hot Water Cylinders / Storage Tanks

We suggest a 300 litre cylinder, closed circuit system with the cylinder located inside your home. The cylinder has an electric element to boost heating when there is not enough solar collection. It is also possible to use gas as the boost.

Coopers Cylinder by Rinnai

The Coopers Hot Water Cylinder is manufactured in the U.K. using top grade 2304 stainless steel and exceptionally good insulation. The cylinder has a heat exchange coil, 3kW back up element for hot water production in case of an interruption to the gas supply and a 20 year limited warranty. With the addition of a second coil, the cylinder can be configured to use multiple energy sources. Say gas and solar, electricity and wood....
