Therm Products heaters

We offer a large choice of Therm Products heaters, used by many spa brands: Sundance Spas / Jacuzzi, Dimension One, Vita Spa, Arctic Spas, CalSpas, etc. Therm Products heaters and parts, also known by the trade names of TruHeat, Aquatemp Products, Related Metal Products (RMF), are now a division of the California-based brand HydroQuip, so it is possible that a heater is listed under two different names, but it is still the same heater! If you're in need of assistance to find the right heater or part, feel free to contact us.

If you notice a problem with your heater (isn't heating correctly, or at all), here are the different possible causes, and what you can do to fix it.
