Therm Products has been a leader in the hot tub industry for more than 40 years. They are known by the trade names of Caldesso, TruHeat, Aquatemp Products, Related Metal Products (RMF), Thermcore or Therm Products. Their primary products include low flow and flo thru spa heaters, electric heater assemblies, heating elements, blowers, heat exchangers, residential & commercial rails, and UV generators. Therm Products are reliable and are some of the best built replacement products in the spa industry today.
IMPORTANT NOTE for Sundance Spas: This Smart Heater has a slightly smaller dry well. When installing these heaters into spas manufactured prior to April 2007, you can no longer use the OEM Hi-Limit Sensor since it is too large to fit into the new heater's sensor well. You will need to replace both the Smart Heater and Hi-Limit Sensor (6600-168) as a set.
