my home made hot tub for less than $100

This is the hot tub I built for less than $100NZ. This little burner heats the water in about 4 hours - enough time to cook a decent feed on the top.

See what it's like 4 hrs later: http://www.youtube.com/watch?v=JeCMIcnvAlI

and here's how to make one yourself: http://www.instructables.com/id/How-to-build-a-wood-fired-hot-tub/

how well does the thermosiphon work? I'm making one just now, but was thinking I would need a punp to circulate the water through the stove. Also what is the waterpipe like inside the stove? I was thinking on making a copper coil

As far as moving water thu the heater the thermosiphon works pretty well. You do have to stir the water in the tub to mix the hot and cold layers. The stainless coil makes 2.5 turns inside the heater before it comes out. Next time I'd put the coil higher in the heater so it absorbs more of the heat from the flames and exhaust gases and I'd put the fire at ground level. Right now the cold coil quenches the fire a bit and causes creosote to form. Wouldn't be as good to look at tho... Good luck!

It circulates through the natural effect of rising heat (thermosiphon). As the water gets hot it gets lighter and rises through the spiral. This drags more cold water in through the bottom pipe.

where do you get plastic container

[velob0y]

I bought it on Trademe (the kiwi equivalent of ebay). I hear you can pick them up for nothing at some places.

@xOriginalMT Yeah man, I hear what you're saying.

Its impossible to add water chemicals to a hot tub.

Fuck you.

WOW, that is so cool, I love how you built the boiler with a sense of humor. Great Job. You have to see this new version we have in the US now, called the FireHotTub

AWW COOL! I want 1 but my dad says we will build it in 3 - 4 - 5 years :'( 

[ghoster69]

The Argau Camping Toasters would be a great accessory
