Warning: If you angle the pipes downward, circulation will stop. The heater won’t function properly, air bubbles may form, and this can damage the unit.

Types of Heaters

• Interior Heaters
• Exterior Heaters
• Integrated Heaters

Choosing the Right Metal for Your Stove

• Stainless Steel 304: Resists chemicals like chlorine used for water disinfection but is not resistant to salts.
• Stainless Steel 316: Resists both chemicals and salts effectively.

Note: If you choose a heater made from stainless steel 316, the chimney set will be made from stainless steel 304.

Heater Size and Power

Heater sizes are measured in kilowatts (KW). A higher KW means a more powerful heater that will heat the water faster.

Important Note: Avoid using a heater designed for hot tubs with a capacity of 1000-3000 liters in a water tank or swimming pool that holds more than 3000 liters.
