Standard heater coil (25.4mm tube) with fireguard
A fireguard will enhance the thermo-syphon effect of your heater coil, containing the heat of the fire and channeling airflow more effectively.The heater coil:
- 6 metres of 1 inch (25.4mm) stainless 304 steel tube (with a 1.5mm wall)
- inner diameter - 300mm
- outer diameter (including the smoke guard) - approx. 362mm
- approx. 180mm (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).The fireguard:
- made from 0.9mm stainless steel sheet
- fitted and welded around the coil.
You can add heat-resistant hose, brass bulkhead connectors and more to this coil. Check out the other items in our shop and just click 'add to cart'.
We can also weld British Standard Pipe threaded ends onto our heater coils. However, this require your measurements for connecting your heater coil to your hot tub to be very precise. If you are interested in having threaded ends welded to the tails of your heater coil, please contact us via email or telephone first.
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.
