External Hot Tub Heaters

Our hot tub heaters are made of ✓ high quality marine aluminium or ✓ stainless steel. Aluminium stoves are ✓ up to 30% more effective than the stoves made of stainless steel.

Stainless steel heaters on the other hand ✓ can resist corrosion in most acids, alkaline solutions, and chloride bearing environments, even at elevated temperatures and pressures.

High-quality MIG welding ensures the perfect end result. We check and test impermeability of all welded seams.

How the external heater works: the water circulates between the stove and the tub using the principal of thermosiphon (the movement created by rising hot water) and eliminates the need for a circulating pump or electricity.
