TimberLine Wood Water Stoves are an alternate way to heat a hot tub or spa! This 100% Stainless Steel water boilers produce about 35,000 BTU of heating capacity by only using wood. You can now heat a medium-large hot tub in hours!  These are ideal for off grid applications or to supplement pool and spa heating costs. 

The TimberLine Wood Water Stove naturally circulates the water using no electricity. Its design is based on Thermosiphon; the hot water rises and exits via the top port. At the same time cold water is drawn in to the heat exchanger via the bottom port.

Thermosiphon System -Standard

Both the stove body of the Water Heater and the firebox are made with high quality AISI 430 grade stainless steel. The heater can be left outside without the danger of rusting or burning-out. A specially designed vented smoke outlet provides secondary combustion of unburned gases, thereby reducing smoke emissions and chimney sparks. The heater comes with a 8' of stainless steel stove pipe.

The Wood Water Heater utilizes a sophisticated heat exchange design for efficient water heating. The stainless steel stove body surrounding the firebox is a double-walled water-jacket with a 1.5-inch space between, making the entire firebox (except the front) a heat-transferring surface. Additional heat transfer takes place in a water-filled baffle tubes that runs horizontally through the firebox. The baffle deflects the path of the fire, so it gives up more heat into the water jacket before going up the chimney.

Heat is easily controlled by adjusting the air draft control for heating the water and maintaining the water temperature.

The dimensions of the TimberLine CampFire Stoves are 17" wide x 26 1/2" long x 20" high with at total weight of 40 lbs. The fire box can accommodates 24" logs. The Campfire water stove comes with a 3/4" drain plug to completely drain the internal water jacket preventing any damage that could be caused by freezing.  Also include are a temperature gauge to regulate the hot water and a safety pressure valve.

The heating time varies by the amount of water capacity of the tub and the starting temperature of the tub. Generally the TimberLine Camp Fire Hot Tub Heater will raise 100 gallons by about 42 degrees F per hour. The unit comes complete with everything you will need including the through ports. Included is a 2 year warranty against Manufacture defects. The TiberLine Wood Water Stove is perfect for cabins or anyone who wants to enjoy a hot tub without any pump noises. Great for the do-it-yourself who wants to build their own hot tub.
