Oventrop Solar Systems are a complete line of solar collectors, solar controls, radiant floor systems and solar hot water storage tanks.

Oventrop’s evacuated tube collectors are best suited for the climate in the Pacific Northwest.

The principles of solar hot water heating are very simple.
Collectors absorb the heat from the sun and transfer it to the water or
other liquid flowing through the risers, in the same way that water in a
garden hose will heat up if left lying in the sun.
