Wood fired hot tubs where used in days when there was no electricity or access to natural gas. But even today wood fired hot tubs are available in market for those who want to experience the natural experience of soaking in the spa heated by burning wood. The basic principles of the wood-fired tub are similar to that of electric tubs. That is the water from the heating element passes through the heating element, then through the filtration system and back in to the tub. The work associated with the wood fired hot tub is bit more than the electric or gas hot tub.

Difference between wood fired tub and other heating options

Wood fired tubs cannot keep you water at an exact temperature as the other options do.  That is the water is really hot on the top and cold at the bottom, to combat this you need to use a paddle to stir the water occasionally. The wood fired tub has a heating stove focusing on maintaining the proper water level to cool the heater and the flow of air. The popular wood-burning water heater is the Chofu model- a Japanese product. This model eliminates the need for a circulating pump or electricity. Now you can have a hot tub without pumps, chemicals or high maintenance. This heater can be fitted on an existing tub wood tub. The stove body of the Chofu is made of stainless steel and will last for years if well maintained. For reducing smoke emission and chimney sparks it has a unique feature of vented collar that provides secondary combustion of unburned gases.

Tips to light the stove.

When lighting a fire in the stove use paper for the initial ignition, followed by wood chips and finally put in the logs. More wood you add faster the water gets heated and longer will the water remain at the proper temperatures.

If the water becomes very hot damp the fire and reduce the airflow into the stove. This will quickly cool the water. Take special care to maintain the wood heater exterior. This controls the cooling system.

Use high-heat low -smoke fuel to reduce the amount of smoke and also make sure that the wood is dry and not green. Keep the stoves chimney clean and obstruction free.
