Types of Heaters

Submersible Heater

  • Submersible heater is perfectly adapted to be used inside a hot tub ensuring efficient water heating.
  • Snorkel stove size determines it‘s power and hot tub size application.
  • This heater is mounted inside the hot tub, therefore saving space around it and it is easier to transport.

External Heater

  • An external wood burning heater is safer compared to internal hot tub heater because they have no risk of touching the hot metal while being in the tub.
  • External heater saves space in the hot tub, allowing to get a smaller hot tub for the same number of people.
  • It is easier to maintain and clean.

Integrated Heater

  • The integrated heater’s operating principle is as exterior, but it is installed under the tub, saving space in the yard.
  • This heater has a glass door as standard and also plays the role of a garden fireplace until the hot tub is heated.
  • Integrated heater is hidden under the seating so there is no risk of skin burn.

Heater Accessories

Stainless Steel Heaters

We manufacture heaters from stainless steel of two grades:
316 – highest quality, 304 – optimal quality/price ratio.

AISI 316 - Excellent Chloride Resistance

When it comes to 316 stainless steel, you can expect better resistance to corrosion and pitting from chlorides than you would with 304 stainless steel, as well as higher levels of strength at elevated temperatures.

AISI 304 - Good Overall Resistance to Corrosives

It is a highly heat-resistant grade and offers good corrosion resistance to many chemical corrodents, as well as industrial atmospheres.
