Working Principle

The kit operates on the natural thermosiphon principle: cold water from the tub flows into the bottom of the stainless steel coil, absorbs heat from the burning wood as it circulates through the spiral tubing, and rises back into the tub as warm water due to density differences—creating a continuous, pump-free heating cycle that gradually warms the entire tub to a comfortable soaking temperature (100-104°F)

Quick Assembly Guide (10-Minute To Setup A Wood Fired Hot Tub!)

1. Prepare Your Tub & Install Fittings. Gather a clean, sturdy tub/barrel (metal, ceramic, plastic, or drillable material). Use a drill to create two 25mm-diameter holes on the side: one near the bottom (water inlet) and another 35cm higher (water outlet). Ensure the upper hole sits below the tub’s waterline when filled. Install the matching tub fittings (based on your tub’s thickness) and seal tightly to prevent leaks.
2. Connect Tub to Heater Coil. Use two hoses (insulated hoses recommended for faster heating) to link the tub fittings to the heater coil. Match the bottom tub hole to the coil’s inlet and the upper hole to the coil’s outlet for proper circulation.
3. Secure Connections. Tighten all hose-coil and hose-fitting joints with included clamps. Double-check seals to ensure no water leakage—this ensures efficient heat transfer and safety.

Q: What diameter hole should I drill in my tub?

A: You will need to drill two 25mm diameter holes in the tub wall. If your tub is steel or ceramic, please leave a note when ordering, and we will send a special drill bit.

Q: What is the maximum tub wall thickness your fittings can clamp?

A: Our standard tub fittings work with tub walls up to 50mm or 70mm thick.

Q: How long are the hoses you recommend?

A: You can choose 50cm / 100cm / 150cm / 200cm to connect your tub. You may also use your own hose with an internal diameter of 25mm,we suggest the hose need to be standing high-temperature and has good insulation performance, length does not exceed 200cm.

Q: Is it easy to remove the coil kit from my tub?

A: Yes, the coil kit is designed to be portable. You can attach or remove the coil and hoses from the tub fittings quickly, usually in 30s.

Q: Should I drain the coil in freezing weather when not in use?

A: Draining is optional but recommended. The coil is made of thick stainless steel that will not burst from ice expansion. However, draining the coil will help speed up heating for your next use and prolong its service life.

Q: How long does the coil take to heat the tub water?

A: Heating time depends on water volume, tub`s insulation method, starting temperature, and outdoor temperature. In our tests, a standard 200-gallon (0.80 m³) tub heats from 18°C (64°F) to 40°C (104°F) in about 90 minutes, or from 13°C (55°F) to 40°C in about 2 hours.

Q: What is the warranty period for this coil kit?

A: We offer a 1-year warranty on all components of the wood fired hot tub coil kit, covering manufacturing defects and material failures. The warranty excludes damage from improper use, neglect, accidental impact, improper installation, or normal wear and tear (e.g., surface scratches from regular use).
