  • Solarfocus Vacuum Tube Collectors

A well designed system will provide approx. 60% of your annual hot water needs with the main benefit being in the months March to September. In this period there will be minimal need to use back up heating (oil, gas, electricity etc.) and on sunny days water temperatures of 50°C – 60° C would not be unusual. (35° – 42° is a comfortable showering range for most people). In periods of extended cloudy weather systems obviously won’t perform as well and that’s the reason solar storage cylinders are larger than the ones used for oil / gas systems, i.e hot water generated during the previous sunny day is available for use.

However, even in cloudy weather the system is still delivering energy as the solar heating coil is located at the very bottom of the cylinder. This means that water entering the cylinder at say 10° can still be heated to within 4 - 6° of the panel temperature.

A well designed and properly installed system will provide energy all year round, will be virtually maintenance free and have a design life of 30 years plus. The quantity of energy delivered by 1 square metre of solar collector in one year is approx. 530KwHrs so a typical 5m system would provide 2,650KwHrs of energy or the equivalent of 265L oil. This energy is free, non polluting, independent of political or economic events and is yours to harness.

Customer-References

While we considered several providers we were very impressed with the knowledge and enthusiasm of Matthew Collison of FPI Solar and we accepted his competitive bid for the project. We were very impressed by how neat the work was with Matthew going to great trouble to maximise the space in our hot press once the equipment was installed.

Attic & Wall Insulation

Thankfully there’s a simple and inexpensive solution (in the shape of glass fibre, rock wool, cellulose etc.) but it’s surprising the number of poorly insulated attic spaces we still have. Provide service walkway from access hatch to tanks. Lay 150mm glass fibre quilt between joists. Insulate water tanks and exposed pipework.

FPI Solar - Energy Conservation

In new builds it’s relatively easy to plan for renewable energy heat sources such as geothermal or solar but in existing dwellings it’s a more expensive proposition as more work is involved. It makes sound sense in these circumstances to improve the efficiency of the existing heating system rather than replace it and installing a new boiler is often a good starting point.

Geothermal Heat Pumps for Space Heating

However it’s important to remember that for all heat pump systems one fundamental does not change: The greater the difference between the temperature of the source and the output hot water temperature, the less efficient the unit becomes. The clever thing about them is the way they use electricity to operate a compressor and refrigeration circuit to move heat from a low temperature source to a high temperature source.
