I have been building camping hot tubs for years using copper in the fire
here is a link to some old ones I've built
Maybe because I've built so many I'm less motivated in spending the day setting it up, gathering wood, chopping wood, and keeping the fire stoked all day to be ready at night.
There has to be a better way
something that is easy to set up, fast to fill, and quick to heat.
This is where I'm at with my search
I'm looking for a used one of these with a broken pump/heater because all I need is the tub
Person capacity: 4-6
•Water Capacity: 254 gal.
•Filled weight: 2,701 lbs.
•Inflated size: 77” x 28”
for a quick fill and I also have other uses for this other then just a hot tub.
This does 140 litres per minute (31 Imp. Gal per minute)
To heat it quick I'm thinking this. it will heat the back of a shortbox truck in about 3 hours and will run the tub for two nights on 20lb propane
