Solar Thermal

Solar thermal technology uses the sun’s energy, rather than fossil fuels, to generate low-cost, environmentally friendly thermal energy. This energy is used to heat water or other fluids, and can also power solar cooling systems. Solar thermal systems differ from solar photovoltaic (PV) systems, which generate electricity rather than heat.

Solar Thermal System Types

Solar thermal technology comes in many shapes and sizes, and is used in a wide variety of commercial applications. Commonly seen types of solar thermal systems include:

Domestic Hot Water (DHW) systems
These include active and passive glycol systems (both closed and open loop), as well as drainback systems

Swimming Pool/Hot Tub-Heating Systems
There are closed loop glycol and drainback varieties

Space Heating Systems (radiant)
Usually attached to a DHW system

Combi Systems
Combination of any of the above
