Tail length is measured from the outermost edge of the coil to the end of the tail. Made from 0.9mm stainless steel sheet, 250mm tall. Fitted and welded around the coil. Enhances the thermo-syphon effect of the coil, containing the heat of the fire and channeling airflow more effectively.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 central Scotland. We can make custom heater coils for wood-fired hot tubs and similar in a variety of sizes with regard to overall diameter, coil pitch, height, tail length and welded-on fittings.
