has anyone done this? is there a way to make your own wooden, wood-or propane heated tub for the back yard? it seems the chofu heaters are common but pricy- i checked out- www.islandhottub.com or www.cedartubs.com, both sell the stoves for 700-800$ which seems so expensive, this isnt even including any piping.
i looked at some diy examples where folks just used a galvanized stock tank, which im assuming is more economical then buying a pre-fab cedar tank.

No ideas, but I have often seen ads for wood heated hot tubs and wondered how well they work? With all of our wood, it seems like it might be a nice idea.

We got a free used hottub, and turned an old upright barrel woodstove into a water heater for it. We used copper tubing to build a thermosiphon system. It heats 250 gallons of water in 2.5 hours.

We have one on the property where we rent (a semi forming ecovillage). The heater is broke and like you say it is around $900 for a new one. The PP's idea sounds like a good one!

Blissful Mama to DD-(5), DS-(6) and someone new due in November!

You can post on craigslist for a used hot tub.

You can go with a small solar hot water unit for about $1000. (EFI.org - need commercial account login) You would need to add a small pump to circulate the water and have a plan for draining the unit in freezing weather.

We LOVE our Chofu from island hot tubs!!!! We bought a 6' galvanized stock tank and use rigid insulation for the top - nothing on the sides. Easy to take care of and great fun.

still learning
