Wood fired hot tub stove,how to build a mailbox post out of 4x4,pvc jungle gym plans - For Begninners
Well this year I wanted to try something different instead of using the pump to circulate water through the copper tubing method.
It doesn't take but 3-4 splits of wood to keep this tube cooking every day to about 105-110 deg.
I finally welded 8 brackets around the top edge for hold downs and the leaking seems to have stopped.
No way to drop temp very quickly, just takes some getting used to how much wood to burn to gain the temp needed. Yea Dianne All one needs is a sealed stainless steel container to build a fire around, or under in my case, and heat up the water without electricity.
The heating time varies by the amount of water capacity of the tub and the starting temperature of the tub.
When the fire is going I can really feel the suction on the bottom hose in the tub, the theromosyphone works great. 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. A week later, UPS dropped off two boxes in our driveway — the surprisingly light Chofu and a separate box containing four 2-foot sections of stainless steel stovepipe. This one won't be sealed so it will be critical as to the positioning of the barrel next to the tub. Additional heat transfer takes place in a water-filled baffle tubes that runs horizontally through the firebox.
Because the Chofu is free-standing, it can be hooked up to just about anything that can hold water, so we thought an old stock tank would work.
Water circulates by the thermo-siphon effect: Cold water comes in the lower inlet, is heated in a jacket surrounding the firebox and flows through the top outlet into the tank. The baffle deflects the path of the fire, so it gives up more heat into the water jacket before going up the chimney. The TiberLine Wood Water Stove is perfect for cabins or anyone who wants to enjoy a hot tub without any pump noises. In the winter, our little tank goes from nearly freezing water to a comfortable soaking temperature in less than one hour with just an armful of wood.
