Solar Thermal is an effective way of heating some of the water for a property - up to 65% in winter and up to 100% in summer.
What is required is a south facing orientation on which to place solar collectors. There are two types of solar collectors. Flat panels tend to be the most robust and have a solid flat front that many find more aesthetically pleasing. Evacuated tubes though are thought to be more efficient and weigh less. A solar thermal package is completed with solar storage cylinders, high temperature pipe insulation, mixing valves and roof lashings.
The heat produced might also be eligible under the Renewable Heat Incentive.
