Heaters Print

compact-heaters

Duraflo Compact Series heaters are a popular addition to any Hydro system by maintaining the water temperature of your whirlpool bath.

Important Note: Please note that these heaters do NOT initially heat the water, and are used ONLY to help maintain the existing water temperature of your whirlpool after the initial hot water is added.

Description:The T-Heater is even more compact than our previous model.  The unit installs directly on top of the Duraflo pump and connects to the power source via a convenient 3’ power cord.  The T-Heater can be used with both 3/4” and 1” systems.  A second heating unit, the size of which is amazing, is our new In-Line Heater. The unit resembles a small tube and installs directly into the systems hose line near the point where the water enters the pump.  A sensor activates both the T-Heater and the In-line heaters, that senses when water is present in the system and when the pump is running. They are also UL recognized for worry free operation.
