The stainless steel wood fired hot tub heater and chimney circulate the water in the tub and require no electrical pumps!

Wood Fired Pool Heaters

WOOD FIRED POOL HEATERS

Wood Fired hot tub & pool heaters are an ideal way to extend the swimming season and save $$$ on operating costs. These heaters are specifically designed for hot tubs and smaller pools or lap pools. These heaters use a unique physical principle called Thermosiphon. Thermosiphon is the principle that hot water rises. It is used in many heating applications and is ideal in low flow requirements such as pool or hot tub heating.

External Wood Fired Heaters

EXTERNAL WOOD FIRED HEATERS

A stainless steel fire chamber contains a double wall. The inside of this wall is filled with water. As the fire heats the water jacket, the hot water rises to the top, at the top back of the fire box is an exit port where the hot water rises to and is pushed through to the top surface of the pool or hot tub. As this water moves out of the water jacket colder water is deriving out of the bottom of the pool into the water jacket where it is heated and forms a natural circulation. The hotter the water is the faster this circulation occurs. Our Products: CampFire, Blaze, Inferno and BonFire.

Internal Wood Fired Heaters

INTERNAL WOOD FIRED HEATERS

An Internal Wood Fired Heater sits inside the hot tub or pool and is mounted to the side wall. It is a stainless steel fire chamber that uses a very effective “rocket stove” principle to create a powerful fire. The fire actually sits in the bottom of the vessel and air is deriving out of the top though a chamber to the bottom where the wood fuel is located. The exhausting smoke is then expelled out the chimney. The Internal wood fired stoves can provide as much as 100,000 BTU of energy per hour! Our Products: Volcano.
