Solar Thermal - introducing ThermoMax vacuum tube technology
With a typical active solar heating system layout, an electronic controller constantly compares the temperature of the solar collectors with the temperature of the water in the cylinder.
Whenever the collectors are hotter than the cylinder, the controller activates the systems' circulating pump. A mixture of antifreeze and water is then circulated through the collectors and the cylinders' heat exchanger - thus heating the cylinder in just the same way as a central heating boiler.
Installation is straightforward and usually involves changing the existing cylinder to a new twin coil version, and connecting the solar tubes fitted on the roof tiles.
There is little disturbance to the household as most of the work is on the roof and in the airing cupboard and is usually completed in 2 days.
A solar system can work in conjunction with virtually all other types of heating systems and requires very little maintenance - just a check-over every 3-4 years (many of the first systems are now 20 years old an still going strong.)
For most homes we recommend the Thermomax tube system. This world leading UK-made system uses vacuum tube technology to give total insulation against cold winds and temperatures. It works solely on daylight (rather than clear sunlight) - allowing it to work in cloudy conditions, and providing good year-round performance. A 20-tube system, covering an area of 2m squared, is suitable for a 3-bedroom house. This should supply 90% of hot water from April to November and pre-heat water throughout the winter months.
Grants
Solar Thermal grants ended on 24th May 2010. The Renewable Heat Incentive has now been confirmed in place of the grants system. The initial tariff rate for solar thermal is stated at 8.5p/kWhr, which applies to commercial systems only. For further details please click here
