FAQ

Can I get a longer hose?

The standard hose length is 100cm which is sufficient for most setups. If you need a longer hose, please contact us before ordering with your desired length, and we will provide a custom quote.

Will the system melt from high-temperature water?

No. All piping parts are made of stainless steel, and the hose uses heat-resistant silicone that can withstand temperatures from -200°C to 200°C. The system is designed for high-temperature use and will not melt under normal operation.

Dois-je vidanger le serpentin en cas de gel ?

In very cold conditions, you can drain water from the coil to protect the system and improve heating speed for next use. Even if you forget, the thick stainless steel construction will not crack or burst from ice expansion. To drain, simply loosen the clamps and remove the hoses from the coil ends.

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

Yes. You can disconnect the coil in about 30 seconds by loosening the clamps and removing the hoses from the tub fittings. If you want to keep water in the tub after removal, let us know when ordering, and we will include sealing caps to restore your tub to its original state.

Is this coil compatible with any hot tub or stock tank?

Yes. It fits most stock tanks, plastic tubs, wooden hot tubs, and barrel tubs. You only need to drill two 25mm holes for the fittings. Our tub fittings work with wall thicknesses from 1mm to 50mm. If the wall thickness of your tub is more than 50mm, note its actual length when ordering, and we will include a longer fitting.

Is this coil kit safe for bathing?

Yes. The coil is made of food-grade 304 stainless steel and the hose is sanitary grade heat-safe silicone hose, non-toxic, rust-resistant, and completely safe for human bathing.

What’s more function for BBQ grill?

Beside do BBQ food, you also can heat water by putting boiler on the coil, and use it as a stove.

Ce kit permet-il de maintenir la propreté et la sécurité des lieux ?

Yes. The included ash collector catches embers and ash, reducing fire risk and mess on grass, patios, or decks. For more safety guidance, see our article on how to use a wood-fired hot tub safely.

Can I use this heater indoors?

No. This unit is designed for outdoor use only, as it uses an open fire and requires proper ventilation. Always use it in a safe, open area.

Comment nettoyer la résistance après utilisation ?

Le nettoyage est simple : il suffit de rincer le serpentin à l'eau claire. Aucun produit chimique particulier ni entretien compliqué n'est nécessaire.

Can I leave the heater outside year-round?

Yes. The stainless steel and accessories are weather-resistant. For longer lifespan, we recommend storing it in a dry place during long periods of non-use.
