Hot Tub Heaters

When the pumps run fine but the temperature won't hold, you're in this collection. The 5.5kW heater family covers every Arctic Spas equipment-bay layout — straight Flo-Through, 90-degree elbow, and 90-plus-45 compound — all with the cord pigtail ready for the motherboard. Around the heater itself: the Global/Gecko hi-limit probe that fixes overheat lockouts, the pressure switches that clear FLC flow errors, split-nut unions, and the flat gaskets and L-rings that seal the most thermally stressed joints in the spa.

Heaters last 5-10 years; scale is what kills them early. A Scale Free routine from our water care range is the cheapest heater insurance there is. Heater work is 240V — most owners book our service team. Bring a photo of your equipment bay to any showroom to match the configuration.
