No electricity! No cables! Just lots of hot water for your larger wood-fired hot tub :-)


Extra long, stainless steel,hot tub heater coil made from extra wide (32mm) tubing. For heating larger hot tubs using sustainably-sourced firewood - no electricity or cables required!

This design has been created specifically for the international market, as the detachable tails make allow for a smaller parcel for overseas shipping purposes.

The heater coil:
  • 12 metres of 1&1/4”(32mm) stainless 304 steel tube (with a 1.5mm wall)
  • inner diameter - 300mm
  • outer diameter - 360mm
  • coil height - approx 400mm
  • comes with 400mm detachable tails with 1" BSP threaded ends welded on (tail length is measured from the outermost edge of the coil to the end of the tail). The tails are attached and detached via additional 1" BSP threaded ends and 1" brass sockets.
Please note that we can also make this coil with the detachable tails, but without the final 1" BSP threaded ends at the end of the tails - please contact us for further details.
