Description

Ideal for using as part of a set-up to heat water using responsibly-sourced firewood – no electricity required.

Available in 25.4mm and 32mm – Our 32mm tube coils have a 50% greater internal volume than  coils made with 25.4mm tube.

Inner diameter – 300mm
Outer diameter (including fireguard) – approx. 362mm

Approx. 170-230mm (6 coils) high – works well with both wood and charcoal. Comes with 300mm tails (tail length is measured from the outermost edge of the coil to the end of the tail).

Our fireguard is made from a 0.9mm stainless steel sheet, fitted and welded around the coil. It enhances the thermo-syphon effect of your heater coil, containing the heat of the fire and channeling airflow more effectively.

Safety Information

Ensure that the coil is placed a safe distance from your hot tub and is both stable and secure. Please take particular care of how and where you use your heater coil in any settings where children or animals may be present – safety should be paramount at all times. Any attachments/ connectors/high temperature hose you choose to use should be well clear of the flames.

It is advisable to conduct a brief common sense safety check of the setup before firing the coil. The coil should be set away from any thoroughfare and flammable materials etc.

Please note that your cold water inlet and hot water outlet feeds must be below the water level in your hot tub at all times when your coil is in use. If the water line in your tub is below the level of your warm water outlet feed from your coil (or drops below it while you are using your tub) water will stop flowing through your coil and just sit in it, becoming extremely hot. This is called ‘dry firing’ the coil, which is extremely dangerous and will result in scalding hot water or steam coming out of the hot water outlet.

​If you have a stocktank style hot tub, we would advise attaching it to your coil with the hot water outlet below the upper ripples in the tank.
