Solar Thermal Energy is the technology for harnessing the sun to produce heat and therefore utilize it for Space Heating, Space Cooling, Domestic Hot Water, Swimming Pool heating and even Electricity Production.
Solar Thermal Systems are divided in Low Temperature and High Temperature.
Low Temperature systems are used for Space Heating, Space Cooling, Domestic Hot Water and Swimming Pool heating.
High Temperature systems are used for Electricity Production.
By utilizing Solar Energy cuts heating/cooling costs more than half.
