Hot Tub Heaters

Our hot tub heater range is extensive, we stock Balboa hot tub heaters, Gecko spa heaters, Hydroquip, Thermcore, RMF, Spaquip heaters and all the Chinese models in the marketplace.

The Flow-Thru type has a larger diameter manifold and uses either a pressure switch or flow sensor (typically M7 sensors).
These spa heaters function above 15gpm but more commonly over 20gpm.

It is rare that the tube will leak but the terminal bolts can get rusty so always check for this and restore as necessary.

"Low-Flow" on the other hand has smaller 3/4" or 1" tubing. These work with a smaller circulation pump and operate at around 6gpm to 10gpm.

A reed flow switch is commonly used but some may use a pressure switch instead.
