I wanted to test out my hot tub set up before I took it out camping. I headed out to make a fire and see how it worked. Just made a quickey small scale base to lay the tarp in because i was lazy. Only took 1.5 hours to get the water up to 34C. And the fire wasn't that hot yet because all the driftwood is still wet. I imagine it will just take longer to heat up in the full scale final tub.

plenty of hose to place the tub where needed

Pulled the coil out and built up the fire

how long will an average fully charged batt run the pump?

this pump only draws 1.5-2 amps, so you could run it all weekend if needed off a good deep cycle. But its just a pos power fist pump and it says intermittent use only, so I will see how long it lasts. The better pumps run more like 7 amps.

You need more copper. With that little copper it will take you most of the day to heat a tub...more copper the better. you are also better off to get a shurflow 2088 pump. Princess Auto has them on sale from time to time

Nice job, looks like a quick set-up too, no digging holes or nothing...

Agreed! You are going to be very dissapointed when you go full size if you don't add at least 3x as much coil. Remember, it's not just about heating the water, you also need to keep it hot. A tub 4x the size will take more than 4x longer to reach the same temp.

should prolly put teh coil right in the coals of the fire keeps it warm, and the more hose you got the more you loose the heat from the water before it reaches the tub. i used vise grips on the end of the hose to slow the water , the longer the water stays in the heat of the fire the hotter it gets, your tub will heat up faster that way too.

Not as fast to set up.
and it take over five hrs to fill and heat.
Bigger is not always better.

What do you call a hot tub with all women in it?

Clam stew.

Couldnt help myself

Like Honky said....more coil and suprisingly you get more heat if you put the coils "on top" of the fire rather than into the coals( you want flowing heat, not stagnant heat) Also I bring a couple of buckets to hand fill the tub a lot faster than relying on just the pump to fill.

sweet tubs. try one of those inflatable kid tubs instead of the logs and tarp.

Rubiconmike, how does your tub stay together and how small does it get for packing it around?

Some good ideas here. I guess more copper is in order, that's all I had laying around. I was thinking about using an inflatable pool but drift wood was free. I just layed the coil on top and let it settle into the coals. I imagine I will have to upgrade the pump soon. Keep the ideas flowing, could help a lot of people.

hahaha omg thats awsome!!!!

looks awsome i have never done anything like this but doesent the water curculate by itself by having the cold enter from the bottom and hot out the top ?

you could do it that way if you had lots of time.

just remember the more copper the quicker your hot tub will heat.

Most of the kid pools will not work because when the water heats up the sides fall.

Don't over think it. Just drag over some logs and put *2* tarps down. You want the water to be TITS deep when you are sitting down.

Make sure the ground is flat and if you really want to get fancy put down a sheet of plywood.

one more thing. Keep over filling the water if you plan on using it for a couple of days....OR use bromine and shock to keep the water sanitized. If you don't it will be like sitting in a warm toilet.

decent thanks for all the ideas, will have to definatly build a tub one of these days

In the picture above we made the palm trees out of ferns. cut slots at the top of the stick and place the ferns in. I guess we were board we even made a rock water fall in the corner of the tub for the water intake.

oh and those are wings cooking over the fire.


that was a fun camp!

What he said [iagree] ... If you put it in the coals they just seem to cool around the pipe and actually insulate it from the heat, on top is way better. Also I pretty much recommend using an entire 50ft copper coil although your pump may struggle with that distance it does make a huge difference in time. last thing, I found my pump went to fast so the water wasn't in the fire long enough to get real hot. I ended up buying this large ceramic dial from an electrical store that I put inline between the battery and pump. Then I can turn down the voltage to slow the pump, then the water comes out super hot and steamy. The tub heats up very fast ..also makes the battery last longer and pump stays cooler. Just a few tips I've learned over the past couple years ;)

i run my tub off a generator and i pump straight outta the lake through the fire and into the tub. that way the tub is up to temp as soon as it fills up. then i runn it off a small 12v pump to keep the tub up to temp. if i forget chlorine i let the tub keep on filling and overflowing. the more coils the better

and put a valve on the output to regulate the flow and keep the water in the fire longer

what about using an old radiator? for the coil in the fire?

would that work?

it would probably melt the solder on the rad, they are not meant to be put into the flamage.

Great idea. However, I think the radiator would fail. Even with the copper, you must make sure water is circulating at all times. Otherwise you wreck the copper and put yourself in a dangerous situation (steam explosion).

I think your radiator fins would burn/melt off. Also, radiators are soldered... I would think the solder would melt if you wern't cafeful with it.

**Safety note**
Water must be circulating through your copper coils at all times. If water stops circulating (pump pickup gets clogged is the most common reason) be VERY cafeful when getting the water flowing again. The coils can get so hot that they cause the water to instantly turn into steam which can cause an explosion and/or nasty burns. Best bet is to take the coil out of the fire, let it cool for a few minutes, then get the water flowing again.

An old rad would work best if you kept it in the vehicle and used the vehicle to heat the tub
