Heater Dimensions

Chofu Heater

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 10' 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.

Sizing of a Wood Fired Pool or Hot Tub Heater

To size your heater you will need to know the approx. volume of water in your pool or hot tub. Then use the chart to determine approx. heat up times by the BTU output of each heater. Remember the output ratings are MAX BTU and will vary depending on type of wood and flame level.
