compact-heaters

Duraflo Compact Series heaters are a popular addition to any Hydro system, heating the water and keeping it warm. they allow you to enjoy your whirlpool experience longer, maintaining the water temperature for hours, helping to maximize the benifits of your jetted tub system with minimal investment of time or money.

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.
