Internal Wood Fired Hot Tub Heaters have been used predominately with wood hot tubs to rapidly heat the water. However the same heater can be used to heat pools, swim spas and other acrylic and concrete style of hot tubs.
An internal hot tub heater sits directly inside the pool or tub and as such 100% of the heat energy in the heater is transferred to the water. Similar to the external heater, the water around the heater develops a natural convection as the hot water is heated. Hot water is less dense and as such it will rise to the top of the tub and the cold water from the bottom will replace it and it too will then get heated. An internal pool or hot tub heater needs to mount to the side of the tub or fastened to the bottom of the tub as the internal air volume will cause the heater to rise (float).

What Do Others Say About It?
"I purchased my first hot tub stove in February of 2022, it made outdoors in Chicago bearable during the late winter and early summer. I’ve had such a great experience with the heater that I bought a second one for my brothers birthday, best gift I ever gave him!"
