When choosing a wood fired hot tub, they have couple of choices on where the wood fire heater can go.


With internal varieties, the stove is submerged in the water and you’ll add wood through a port in the top. For the sake of safety, it’s usually partially walled off from the rest of the unit, so you’ll lose a small portion of the seating space (usually one or two seats). However, because the heater is submerged, it’s a bit more efficient. It will heat the water quicker and can be managed from inside the tub.


With external heaters, the stove sits outside the unit, but it’s placed low enough that the heat transfers to the water and heats it via thermal siphoning. There is no seating space lost due to the heater, but it might take up to twice as long for your tub to heat.

Pricing between the two versions is comparable, so this is purely a personal decision: are you ok with slower heating or do you want faster heating at the expense of a seat?
