To use, first attach to your hot tub by using any suitable method (compression fittings, radiator hose, welded threaded connections or flanges - please note these are not available with this item). Then build a fire within the coil and allow the hot tub water to heat. Heating time will vary depending on water temperature, ambient temperature and hot tub size - be sure to have a means of checking your water temperature before use and of reducing/extinguishing your fire once that temperature is reached.
We are a small, family-run business in Ayrshire, Scotland. We also make custom heater coils for wood-fired hot tubs and other types of heat exchanger coil. Please contact us for any custom requests.
