The Green Source Store offers a range of solar products including the active solar thermal heating system. This solar thermal system includes Velux system collectors, electronics and pumps. With the active solar thermal heating system, homeowners can save about 50 to 80 per cent of their hot water heating bills each year. The installation cost of this solar thermal system can be recovered in a span of three to seven years.
Active Solar Thermal Heating System
The Velux solar collector panel, included with the active solar thermal heating system, can be mounted on the roof at an angle of 45 degrees off south. At this angle, this high-efficiency solar collector panel has the ability to provide 95 per cent efficiency. The active solar thermal heating system, provided by The Green Source Store, circulates the glycol solution through the solar collectors that are mounted on the roof. The glycol solution is heated up using solar energy. Later, the heated glycol is pumped into the hot water storage tank through the heat exchanger.
The water stored in the tank is heated by the heat exchanger. After heating the water, the glycol solution flows back to solar collectors to repeat the process. The storage tank of the active solar thermal heating system now contains hot water that is ready for household use. In addition, the heated glycol solution from the solar collector panel can also be used to heat the floor when tubing is installed under the floor.
