It is very important to choose the correct heater for your hot tub. A lot of heaters are very small and takes a lot of your time to heat up your hot tub, so choosing the correct heater save your time. We produce both internal and external hot tub heaters. Heater inside the hot tub will be protected with the guard fence and heater that is outside of the hot tub is connected with the heat resistant hoses to the hot tub.
Outside heater materials:
- marine aluminium

Water is circulating around the heater firebox and also in the coil tubes.
