Chop your own wood it will warm you twice. Build a wood fired hot tub and it will warm ya thrice! A galvanized stock tank, recycled bricks, copper tubing, a secluded wooded corner and an evenings work = a long running dream of a wood fired hot tub.
It takes about 4 hours to get the tub to temps of 100+ degrees. The tub can easily fit four people and provides a warm front seat to the sunset, stars and passing wildlife. Baths have always been therapeutic but this tub makes bathing a true ritual and reward.
The copper tubing is coiled inside of the bricks encasing the fire. Either end of the tube is fastened to the side of the tub one on top of the other. As the copper tube heats it pulls water from the bottom tube into itself, warms the water and it’s then cycled back into the tub via the top tube. There is a steady flow of warm water immediately but once the coals are hot and the water is warm, boiling water will jet out of the top tube every five or so minutes. We are very pleased.
