Still finalizing the wood fired heater so this thread will only be about the hot tub part.

I have a decent sized pond and would like a 12 person hot tub next to it. I'm unsure how to affordably filter it because it will mostly be a weekend thing and then drained. Unless i can develop some sort of giant solar sponge filter or something.

The giant round wooden tubs seen nice but by the time i buy the straps and wood AND THEN do all of the work it looks like it would be a pain in the ass and expensive.

I've been as far as to consider renting a mini excavator and just digging a big hole. Place the dirt around the top to help with height and then carve out seating by hand. Maybe throw heavy construction plastic in it and slowly fill to cram the makeshift liner into place?

I may have acess to a giant metal tank without a lid for like $100. The problem is that it's an old tank that had saltwater in it and it has a few holes. I have a stick welder and thought maybe i could weld patch plates in but it's kind of a long shot. It would be badass though. It's about 20 feet wide and 5 feet tall. A buddy said he would help modify an old propane tank for a massive wood heater that will basically just take any chunck of wood 2 people can throw in it. We have a bunch of old pipe and could idle a 3" water pump to circulate water through the goofy hillbilly heater.

Also considering just a smaller 4 person tub to set next to the house and heat with natural gas. Maybe from wood or old logs and cement?

Just fishing for advice and ideas if anyone has any. Especially those with experience doing something like this.

problem I see here is the heat will concentrate on the bottom of that and even tho its filled with water, touching the bottom could cause severe burns. cause well, fire heats metal

Can confirm. I used to be a long haired hippy living in natural hot springs. The cold water sinks and freezes your butt. Warm water will rise up and burn your chest. If you do something like this you'll really really want an electric pump to keep the water moving.

Anon, metal is thermally conductive, and so is water; the heat will evenly disperse throughout the tub. As long as you have the tub far enough off of the ground, and the fire low enough, a metal tub, especially one as big as the one in the OP, will be perfectly safe.

Good call anon! I thank you but i also have a "buffer." It's basically a glorified series of redundant pumps for free or cheap regulated by a drunk certified electrician/plumber.

So far all we know for certain is keep that old fucker away from the whiskey and just keep the water moving if it's got fire under it?

Sweet. I got beer and a backhoe and a pipeline welder for 2 days though.

My idea is an easy feed wood fire from a half moon party deck. The welders get the stove done. We rig up rando pumps, and we dig what we need before setting shit down and i start confiscating CAT keys...

>> No.1770885

Slightly different idea, but would it be possible to plumb copper pipes to snake through an outdoor fire, maybe through masonary that heats up, and then feed into a bath? So you just turn on a cold hose tap and it then feeds hot water into your bath?
Then have a drain?
You could have the pipe that feeds it look really cool and plumb a valve on the drain so it's constantly filling and draining.

I'd also be more keen on trying to find a shit condition nice old cast iron claw foot bathtub and restoring it. Maybe get a few. And so you've got your nice outdoor fireplace with seating and shit around it and then a couple people can sit in the bath and you can fill/drain it each time so it's not gross and it's not enormous so it doesn't take forever to fill.

Just make sure you build it in a way so that you can easily clean the exhaust path, and have tight control over the temperature.

>> No.1770940

>>1770885
That's actually pretty common.
Tub flows from low point to coil in the fire before back to the tub. Heating the coil causes the water to circulate. Can regulate heat by playing with the fire or adding more cold water.

the most important part of the hot tub is the jets and air bubbles. You're just making a giant warm bath.

Pretty sure those buckets are heat treat hardened and it's fucked now as well. They can take some abuse though. I ran a hitachi ex1100 with more welding rods in it than 90% of most welding supply shops.

never heard of evaporation, as long as there is water in there it wont get hotter than 100°C, aint going to do anything to the steel.

As long as there's a backhoe operator in there, it will stay well below 100°C.

Not how this works, you need temperature gradient to heat the water, so the inside wall of the bucket has to be more than 100C (at least a few degrees to heat the water sensibly fast). You also need temperature gradient for the heat to propagate through the bucket, so the outside needs to be hotter than inside.

The water will not get hotter than 100°C, but the steel absolutely will, especially around the heat source.
