Solar Water Heaters

Domestic hot water (DHW) generation for a residence is the ideal application for a solar thermal system, as DHW consumption is typically constant throughout the year. Solar collectors use the energy from the sun to heat water for domestic, space and pool heating applications and are combined with a storage tank, pump, controller and auxiliary back-up to provide comfort and reliability. At Solar Panels Online, we also carry all of the accessories needed to get a solar thermal system running. In addition to solar collectors and absorbers, we also carry temperature controllers, pumps, heat exchangers and storage tanks.

SolarPanelsOnline has a wide selection of solar water heaters for every application, whatever your hot water needs. Solar water heaters can be used in virtually any climate, but the system you choose will largely be determined by your local climate.

SolarPanelsOnline has a wide selection of solar water heaters for every application, whatever your hot water needs. Solar water heaters can be used in virtually any climate, but the system you choose will largely be determined by your local climate.

We carry dependable solar thermal systems for heating household water for both moderate and cold climates. Active open loop and passive solar water heaters work well in environments where there is no chance of freezing. For cold climates, consider an active closed loop, passive drainback, or passive thermo-siphon system, all of which will protect against occasional or prolonged freezing temperatures.
