Chofu Wood Fired- Hot tub heater (No electricity required)

Chofu Wood Fired Water Heaters are an alternate way to heat a hot tub or spa? This is it! This Japanese made "Chofu" stainless steel water boiler produces about 35,000 BTU of heating capacity by only using wood. You can heat a small hot tub in approx 1 hour.

The Japanese have long been famous for their soaking Ofuro style hot tubs and this Chofu heaters is what they use to heat their bath water.

The Chofu water heaters 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.

Both the stove body of the Chofu and the firebox are made with high quality 316 grade stainless steel. The Chofu 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 4" stove pipe adapter. We recommend a minimum of 6 ft of chimney.

The Chofu 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-inch space between, making the entire firebox (except the front) a heat-transferring surface. Additional heat transfer takes place in a water-filled baffle plate 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 with both a high speed and low speed draft control for heating the water and maintaining the water temperature.

The dimensions of the unit are 16" wide x 23" long x 18" high with at total weight of 60 lbs. The fire box dimensions are 18" L x 14" W x 10" H, and accommodates 17" logs. The Chofu heater comes with a 3/4" drain plug to completely drain the internal water jacket preventing any damage that could be caused by freezing

The heating time varies by the amount of water capacity of the tub and the starting temperature of the tub. Generally the Chofu hot tub wood fired will raise 100 gallons by about 40 degrees F per hour. The unit comes complete with everything you will need including the through ports. Included is a 1 year warranty against Manufacture defects. The Chofu water heater is perfect for cabins or anyone who wants to enjoy a hot tub with out any pump noises. Great for the do-it-yourself who wants to build their own hot tub.
