Awesome video man! as an oilfield pump mechanic in west Texas I want to give you a couple tips to make your system better! Please move your water pump as close as you can to your filter coming straight out of the tank! That’s a centrifugal pump which means it doesn’t suck, it only boost water pressure. That loud noises you’re hearing from both pumps is cavitation, pumps will be silent if your pump is right after your filter. Also, all that excess suction line is unnecessary, cut the excess off and move your pump on to the ground level to it’s not trying to pull water up! Other than that your golden!

[@teamClermont]

I appreciate detailed pointers like this from a pro. thanks for sharing.

[@wesley4713]

You ROCK! I've been wondering what a pump engineer/mechanic would say about this setup. I have a further question for you - that pump is rated for 5min use 10 minutes rest (or so). Do you know of a better pump solution that can work for hours and provide good psi? I just bought a continuous duty pump but its not a high out put pressure.

[@fillups9]

@@wesley4713 someone said they used the Camplux JK-4000. What pump did you end up going with? Another poster said that there was a little filter on the valve to the Camplux heater inlet that they removed and it worked better.

[@fillups9]

Can you help me and my set up!? What are your thoughts on the Camplux JK-4000?

Hi, all you stock tank hot tubbers…help, PLEASE! I practically begged my hubby for a stock tank and all the stuff that it takes to make it into a hot tub. I told him it would be super Duper easy etc. we managed to save our money, use Amazon prime days and get all the materials that are suggested in this video we studied the video, watched it over and over again. BTW, good straightforward video. we finally put it all together. We got two full tanks of propane because we did read somewhere that sometimes they freeze up, turned it all on and after about an hour the hot water pump started surging, and then our camplux heater turned off. We unplugged it try it again the camplux heater turned on, but the pump still was surging and then the heater turned off. I change the filter on the pool. We checked the filter on the pump and that looks totally clear. We called the the number on the hot water pump manufacture and they said that it’s not intended to use for this and that it’s too small. We have an 8 foot stock tank and we followed the buying instructions from the video. I see through the comments that a lot of people are having this issue and they talk about the strainer which is a little confusing for me, but is anybody using a different hot water pump that is powerful enough, so it does not surge and turn off the heater? Does anyone else have any issues with their propane gas freezing from condensation? Please help… our 40th anniversary is coming up and it would be so wonderful and healing to get in this hot tub with our kids.

You can actually put pipe dope on the barb fittings for the hose connections. It makes your hose clamp tightening less demanding. Anytime I repair garden hoses with new end fittings, I use pipe dope, Hercules Real-Tuff. It can be used on plastic and be put in to service immediately.

[@kinss1]

Thanks Ryan- your directions are organized , thorough, concise. The great camera work allows us to see exactly what you’re doing.

[@RandallDHoffman]

Ok this is a nice tutorial. I followed it created this with a poly tank. I have a couple of suggestions and changes I made. First since mine is poly you need to drill your holes slow not fast. Start slow until the arbor penetrates the plastic. If you start fast the bit jumps and you risk damaging your pool by gouging out more plastic. Second, do not buy the black poly hoses. They expand like a balloon after the pump and I had mine leak while going into the heater. I bought premade washing machine hoses that are female on both ends. They work great. The incoming line is blue and the outgoing heated water line going into the pool is red. The incoming blue line I had to cut into two pieces to connect to the pump. I needed so more length so I bought another set of washing machine hoses and joined them with a brass coupler. I also placed everything in a wooden box that has wheels. The pool filter, pressure pump, propane gas cylinder are all inside the box. The camplux heater is mounted the heater on the outside of the box. It is totally portable so if we move the pool it can be moved as well easily and is protected from the weather. In the winter I can wheel everything into the garage to protect it. kzbin.info/www/bejne/mKTKZKWvjZqKa68si=oJ8VybnNu7m9lgHe

[@jaysongehri6731]

I was so sad that the season was over and the water was too cold to use. I was nervous to do this. But like with your other videos, it was easy and straightforward! I bought all of the parts you recommended, even went with the largest heater. It took me an afternoon to do everything! I even use a smart plug for both my filter and the heater pump and makes it easy to turn on and schedule through an app. I will say - it does go through propane pretty quickly! But works great! Went from 70f - 100f in a few hours.

[@TheLodgeKY]

How quickly does it go through propane tanks?

[@ashleychatman744]

Thank you so much for your easy and clear directions! I am super new to power tools and DIY home projects but your video and website gave me the confidence to take this on and build my own stock tank hot tub (6' x 2') a year ago and am still enjoying it often. I even upgraded it recently by surrounding it with 4" thick insulation and a beautiful wooden exterior and lid.

[@Rick_Sanchez_C137_]

How much quicker does the tank warm up and how much longer does it stay warm with the insulation? Did you make a cover for the tub with wood around foam insulation to hold in the heat as you are still heating it and to keep animals/leaves/bugs out?

[@ashleychatman744]

@@Rick_Sanchez_C137_ I live in central coastal CA and use the tub about twice a week. Over night the water temp only drops to about 90 but since I only use it 1-2 times a week, the temp usually drops to about 70 then and takes 30-40 min to heat up to 103 (my just right temp). So averaging 1 degree per minute. I think I have the smallest of the propane heaters though. Before the insulation it took about 90 minutes. I put 2" thick insulation underneath it and then did build a lid out of wood and just glued a 2" layer of insulation to that. For the sides I used two sheets of 1" thick insulation as it is much more bendable. I then surrounded the tub with wood planks standing on end like a fence so it looks nice. I hold the wood in place by wrapping two strips of metal strapping around (wine barrel style).

This was an exact replacement for the old one that lasted about 10 years. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

[@Radiofnub]

I was going to make an in-ground tub. Make the floor/shell out of concrete and use your setup to heat it up. Thanks for putting this video together. Nice setup.

[@nickcarter845]

I would probably install the spigots 180° (directly opposite of each other) to maximize cross flow and help heat the entire pool. Thanks for the video!

[@stocktankpools4980]

Not a bad idea. I just didn't want to run a hose all the way to the other side. That said, the warm water stratifies quite a bit so I end up running the filter pump to mix the water.

[@barbaramarowitz]

@@stocktankpools4980 hey, I know you made these videos like three years ago but my husband and I finally got ours all together this past month and then we ran into some problems. I’ve read through all the comments and saw that other people had the same issue, but their issue wasn’t really covered in any replies, we are 63 and 67 years old and saved up to get this together and I really need some troubleshooting help. The hot water pump seems to make a pulsating noise after an hour or so or less and then the camplux heater turns off. We also do not have the orange, hot water pump covered from the weather. But I didn’t think that that would make any difference. We were thinking that that pump is not the right pump or strength to run the 10L camplux propane heater for an 8’ pool. We are not the most handy people in the world so some of the more complex workaround’s are hard for us to understand. I know the people were talking about this enabling some timer on the camplux propane heater, so maybe that is something we need to do which I don’t know how to do. We have invested some significant amount of money and time and our 40th anniversary is coming up and I’d love to be able to actually use this hot tub. Could you give me some update information if you have any .thank you.

Hey! I just did this today with help from you video. I skipped the valve and siding parts just to see if I could recirculate with that pump efficiently. My water pressure in my area is pretty low (asked a few neighbors haha) and once I plugged this in? I could finally go MAX water flow and the heater was SO MUCH MORE EFFICIENT this way. I'm practicing my plumbing while I dig my in ground hot tub :3! Thanks for the inspiration and help! Its soooooooooooooooooooo NICE I cant understate that. AND QUIET!

[@SpynCycle57]

Since the water is being recirculated from the tank, the house water pressure doesn't matter.

It would heat up faster if the hot water return line was on the opposite side of the tank from the cold water line. That way it would draw the hot water across the tank rather than just heating one side of the tank first.

[@joshualozano9895]

@@ADIYHD this makes sense, wouldn’t it also be smarter to have the hot water come in the lower valve? Since heat rises, hot water will flow up and heat the pool faster?

[@jamiheinricher4477]

A few observations about our build. Firstly, we bought the 6’ oval tank 6’ x 2’ x 2’, 169 gallons. It’s perfect for two people. I accidentally bought the 2.11 gal/minute heater, but it works fine for the smaller tank. We alto ran a hose from the tank drain and put the same shutoff valve fitting on it so that it’s easy to drain the tank which we do after a few tubs. We were having declining performance and first thought was the collapsing hose that flattened and shut down flow when it got hot. We replaced all with braided and also brought the filter up near the pump so that it’s easy to get to. Still, we were having problems with ultra-low flow until finally in desperation we took the heater off the cart it’s connected to and actually removed the hose inlet fitting that came with the unit and discovered a tiny cup mesh filter that was totally clogged and once we removed that, all our problems were solved. We had tried so many things to diagnose the problem. So glad we discovered that little filter. If anyone makes this I’d recommend braided hose especially on the suction side of the pump and removing that filter.

[@fillups9]

Jami- do you mean the little blue nozzle?

[@jamiheinricher4477]

@@fillups9 I'm not sure what you mean by the little blue nozzle. I'm talking about the water inlet for the heater. It had a little screen filter in it. It isn't needed (there's a much bigger filter) and it was terribly clogged, reducing performance.

You should have a shield between your building the heater it could burn or blacken the outside paneling. Also if you used shark-bite fittings your pump won't struggle so much. Plus the heat coming off the heater may make black return hose your using limp over by getting hot. Just my opinion.

[@druidworks]

I had the same issues with the pump. I do like the SeaFlow as well. my SeaFlow had the filter right on the side in-line. Have you had any issues with the gas? I found a 2 stage regulator worked best. But now I’m having issues with the flame going out after about 5 minutes. So I think it needs some sort of adjustment. Which I’m not sure what that is yet…

[@SaabAholic]

I have that same Camplux water heater that I use for an outdoor shower. I have a stock tank and will be using it as a hot tub!

[@fletcherchad9434]

I'd put the inlet closer to the bottom and the outlet closer to the middle. Since hot water is lighter than cold water it will heat up faster. The way you have it you are hearing warm water instead of cold so it's not as efficient. Other than that not bad. Maybe plumb in some jets.

[@Treepole]

You would get less noise from the pump if you mounted on a board and set in the ground The house is a big speaker resonator Good stuff Came up with this 7 years with a Claw Foot tub You hit it right!!

[@NIGHTLAMP12345678]

FYI I have a similar style gas boiler it is a different make and without a exhaust flue the flame will fail due to a sensor in the exhaust outlet....this might be why at half a tank the flame reduces as you say the pressure drops which might be why the boiler will not to heat properly it can't get rid of the burnt gasses fast enough without the flue ....it should be able to turn right down to keep warm....hope helps and fixes the problem...also I'm sure you have seen home made wood heaters for the pool which you could plumb into the pool filter to also maintain temp after heater has done its work......good luck, I'm doing something similar myself so watching others all info helps...love the remote idea..nice video.... also FYI the second type of pump you have is a diaphragm pump which is why its quieter than the other one which from the sound is a gear or impeller style..... if you attach the new pump to solid piece of wood and then to your shed it will reduce the sound greatly too.

[@Northsidepost]

NIGHTLAMP12345678 I appreciate the comment because it turned me onto diaphragm pumps. His Seaflo is a 3-chamber 33 series. I saw they make up to a 5 chamber series with their 4-chamber model including a variable flow rate option. Supposedly the more diaphragm chambers the quieter the operation, assuming proper mounting.

When drilling a hole through metal and attaching any fitting using a rubber grommet(seal) it is beat to file down any sharp edges left from drilling. Naturally occurring expansion and contraction of the metals will, over time, wear to the point the seal needs to be replaced. Simply adding silicone may help short term but ultimately, filing each side of the hole smooth is all that is needed.

[@wesley4713]

I think its safe to assume this is hard on the heater. Hard water is also hard on these and will impact heating output/efficiency over time. MFG recommends to increase water flow and decrease temp. Eg - its better for the heater if you don't max the heating output. So if you want to raise from 70degreese to 104 - setting the water output temp to 104 would give increased life span.

Those pumps get very hot with continuous use. Keep in mind they are designed for use in Boats and camper trailors. Install a 120mm computer cooling fan over the pump to keep it cool.

Interesting. Do you think you should have have the inlet come from the bottom because heat rises? Also the service look off of the pump had a gravity restriction. That tube probably should be mounted. What about water freezing in the lines when the system is not in operation?

So what is gonna keep the water left in the heater and the pump from freezing and busting pipes in the winter when you are not running it? I would say where I live at in the Midwest in the winter and you are not running the pump and heater at least every 4-6 hours. The access water in the heater, the circulating pump and the connection hoses will freeze and ruin all that equipment very quickly. Maybe if you left the circulation pump run all the time like in a real hot tub it might not freeze

It was cozy and warm but not hot.The second time I used the rest of the propane tank it wasn’t enough, it heat for 1:30 minutes and then I ran out of propane.

[@sharoncourt75]

😬 that gets a little pricy

[@SFXD24]

Need to insulate the tub. and put a temp controler on it.. Mainting heat is better than heating up every time.

[@AMBaggs]

Question: Wouldn't it be better to have the hot water to enter at the bottom of the tank and take the cold water from the top?

[@JtotheRizzo]

Did anyone else notice that kink in the looped hose of the pump (top right)? That should be cut and connect it in an "S" shape it into the pump.

[@TheLilScarface]

Just bout an 8 ft stock tank to use as a pool / jacuzzi will this setup support this I’d want to use it as a pool in the summer and a hot tub in the winter ?

[@justin7871]

Any issues with the pump? It is rated for a 5 minute on, 10 minute off duty cycle. So running it for an hour or three to heat a stock tank pool may kill it prematurely?

[@wesley4713]

I'm getting the supplies right now to do this project and saw this same problem. This is a fire hazard unless you follow those directions ^. I found a continuous duty pump to try. I wonder if anyone else has found a better solution for the pump. High pressure and continuous duty seems to be very difficult to find. The one I got isn't high pressure but, the heater i got only needs a min of 5psi. Efficient operation requires closer to 60 psi - If I understood the poorly Chinese to English translation properly. lol.

[@fillups9]

@@wesley4713 how did that work? If it went well, can you send me the name of the pump? I’m having the same issue

[@headdown1]

@@wesley4713 I just installed the same Camplux heater and bought their pump as well. JK-4000. It works great..quiet and shuts off as soon as you shut off the switch at the shower head. It has a 90 minute on 20 minute off duty cycle if I recall. 45 psi, 3.3 gpm. Lots of pressure for showers, even at the low flow setting on the heater.

[@Josh-no5qh]

So you didn’t mention how to avoid the pump and lines from freezing? Thoughts

[@Brokenneckj]

Water should be pretty warm if using the heater often. If real concern use insulating the hoses or pipes, yeah you could use cpvc.

[@goldenbanjo197]

The two fittings that come with the heater where you screw on the barb fittings are the wrong h thread. Those barb fittings are course hose thread and the water heaters are water fitting tapered thread.

Hi, I enjoy watching your videos on stock tank pools! Recently, I bought a 150 gallon stock tank. What size Intex pool filter and Camplux hot water heater do you recommend? Thanks.

[@akkellenberger]

So we did this set up last year and purchased off your shopping list. The pump keeps over heating any suggestions??

[@FoodForestBrad]

How would you insulate the stock tank so the metal walls aren't aggressively dumping heat?

[@badoso11]

looks great. only question i have that i can't find an answer too. i do know it depends on how cold the water is to start. how many tanks of propane are used to heat up the pool ? i see that it takes a couple hours. but not the amount of propane. thanks.

[@jessicawebster7890]

I have a 10’ tank and it takes one 20lb propane tank to heat the water about 40 degrees. But beware, the propane tank will get really cold and icy on the outside as you use it (normal chemical process, nothing to do with the weather) so it will get less efficient as it runs out of propane. Solved by putting the propane tank into a tub of water so the outside can’t freeze.

[@barbaramarowitz]

Thanks. My husband is insisting we do not have the correct Cflow pump.

[@718PLENA507]

Love this setup, just have 1 question, anyway to get jets in the tube, to get that jacuzzi effect?

[@mikerisano3912]

If i only wanted the hot tub setup do i need all the stuff you setup in the initial stock tank pool video??

[@KelsiAmouak]

First comment ever on KZbin for me: I am so curious, do you have a list of all of these supplies?

[@Oxy_Cotton]

Those hose clamps have hex bolts as well, much easier than a flat head screwdriver.

[@lnp6]

Why not use garden hoses for the water? Just wondering

[@RoscroweStearc9]

I have a question, I'm really curious the lowest heat setting there is on it?

[@karentemple7200]

Hi, Ryan. The pump you linked is no longer available. There are other options on amazon. What size should I be aiming for? 8 ft. stock pool. Thanks for your time! BTW Your videos are super helpful. Making me feel brave enough to do this on my own. Everyone thinks I'm nuts but I've got this!

[@djbaskin5814]

Easy to operate! Love it!

[@bobbieluvculpepper]

I love this ty do you have any help or feedback for adding Jets and a spa pump? Or anyone on here have any thoughts on how to do that? Would love to see a video of it being done

[@stocktankpools4980]

Good question! I haven't tried that yet!

[@davidkellers8152]

Jets are just return lines from the pump that do not have a diffuser. Some have air added for more turbulence.

[@Brokenneckj]

hose with holes at bottom edges, with air mattress pump. Just like coleman.

[@wesley4713]

You can get a spa-pump and plumb it for jets.

[@garysteffan4624]

did you change your line in and line out for your water lines to braided hose.

[@wildwithoutasaddle1393]

Great video! Excited to get my own 6x2 stock tank pool/hot tub up and running! i was wondering if you might know how much electricity the pool filter and the hot tub pump draw? Or how often you should keep them running? Thanks for the great content here and on your site!!

[@rickmallinson]

What do you do to prevent the lines/filter/pump from freezing in the winter time? Did you put unions on everything and take pump and filter inside when not in use? Tank is obviously fine.

[@natebanchiere3843]

I have the same question

[@delightseeker]

I've been wondering the same thing.

[@chrisshelton3419]

Id either put a cattle water tank warmer or put a thermostatic controller to turn on when the water temperature goes below 40 and bring it up to 50.

[@ZacharySines]

I'd either drain the pool and line or just the lines. Those cut-offs are nice for that.

[@pageljp]

Have you ever tried using your intex water pump to push the water into and through the propane water heater?

[@stocktankpools4980]

Great question! I really thought a lot about that, but in the end the biggest problem is the reduced pipe size of the heater will strain the filter pump and potentially cause it to fail. The filter pump has 1.5" diameter hoses and the heater has 1/2" diameter fittings (that equates to a huge difference in flow area). The filter pump is also designed to be a "low pressure" pump, meaning it would have trouble pushing the water through the bends and kinks of the heat exchanger.

[@xoloitsquintli]

Now that summer is coming up it's time for a follow up video! Let us know how this worked through the winter.

[@stocktankpools4980]

Yes! I'm planning to provide an update at some point! It's been working great though! The biggest thing I've noticed is that I really only use it to heat it to pool temps (80F-85F), as opposed to hot tub temps (95F-100F) because there's a temperature big loss between the two.

[@xoloitsquintli]

@@stocktankpools4980 Awesome! I look forward to seeing it.

[@malk3800]

Could you maybe use a little plumbers tape on the fittings? Just as a back up measure?

[@stocktankpools4980]

Mal K I used some Teflon tape on a few of the fittings the first time around (before filming) and it didn’t really make a difference. The biggest thing is to make sure all the gaskets and O-rings are in place (they can fall out easily during installation) then you tighten the fittings with your rusty pliers :)

[@ke0kie]

Propane usage? Would you recommend this over a electrical-powered heating solution for a permanently installed stock tank/hot-tub? Trying to decide whether to use propane or electricity to heat my permanently installed 10' stock tank pool, and if going propane seems logical I should choose the Complex 16L unit (The biggest one), but I'd really hate to be swapping propane tanks constantly or too periodically, making electric seem much more appealing long term..

[@TheLodgeKY]

What did you end up doing?

[@SpynCycle57]

The pump should be mounted lower than the water level in the tank. That way, the water will gravity flow to the pump, reducing the work load on the pump.

[@quantumofconscience6538]

Not for that sort of pump. A $100 marine pump siphons up to 30 feet (level) with the water. Always best to put water in the tube but for 15 feet you don't have to.

[@pbstrickland]

Question, do you keep your pump going during the times the temp goes below freezing and keep the propane off, to avoid freezing lines.

[@BrooksDuesterhoeft]

Any thought about just using your filter pump in line with the heater? Possible or not possible?

[@heygraberyo]

I’ve been wanting to do that for a while, use a T connector with intex plunge valve and convert down to 3/4” hose into the heater

[@cartoonkirk]

Does your camplux over heat and shut down after working perfectly for weeks ? I have to adjust the water and gas output to get to 146 degrees Less water thru Less gas use Or the unit will shut down Last week it was going to town at 151 degrees

[@SFXD24]

It's states 125 deg in the book or it will shut off

[@brendanaiello]

How long does the propane tank last? Are you thinking about adding jets?
