[@flojotube9323]

@HomeMadeModern - It’s BIZARRE to see the size of your channel & then seeing ONLY 247 COMMENTS!!! I mean, this video is WELL MADE, doesn’t drag on, & interesting to ANYONE... There’s even a CLICKBAIT HOTTIE!! Every box checked, but still nowhere near the deserved engagement - YT is a strange beast... ANYHOW - IF U SEE THIS - I’m currently fiddling with some water PUMPING/HEATING ideas myself (hence my finding your great video!) and ONE IDEA instantly popped into my head FOR YOU TO CONSIDER: I know you stated you want to explore other “On-Demand” “PROPANE” heating ideas, but IF you’re open to the idea of ELECTRIC HEATING (since SOLAR & mobile power banks have come a VERY LONG WAY), I do know of 1 method that’s SUPER DIY // SUPER LOW BUDGET // SUPER EFFECTIVE which I’m hoping to share with you... It’s difficult to get specific in the comment section especially when the chances of BEING SEEN by the creator average at around 9%... So, if you DO see this & would like further details, please don’t hesitate to email me - at - protonmail - d0t - C0m - by simply adding my YT name to the @ front!! (Code words to avoid algobots & trollonaughts) Having said that, the basic concept of this method is quite simple... Using ANY garbage can sized container, drum, whatever, you can ibstall however many SUBMERGIBLE HEATING COILS you need near the bottom of your container (by inserting them thru the outer wall, and sealing the hole around the coil(s)) I’ve seen this method utilized for a DIY homemade solar power harvesting project (I believe, but can look back to verify if needed) and the water inside the container became VERY HOT within a short period of time using 2 large coils... Then you’d obviously insert your intake/outlet scenario of choice and BINGO, hot water... Now ANOTHER METHOD (which I’ve personally done) is creating a COMPLETELY SOLAR POWERED WATER HEATING SETUP that is BUDGET FRIENDLY, quite an EASY concept to grasp, and honestly?? PRETTY FUN!!! You may have seen this or even have done this yourself in previous videos, BUT this method requires the use of a thin walled black tubing (PLENTY of it; 250FT+ for best results) which your water would be pumped (using a surprisingly LOW POWER pump) FROM your pool/tub into a MASSIVE TUBING COIL that you’d design using that same continuous length of tube... This “coil” or “spiral” of tubing is where your MAGIC happens because you’ll be placing it in a location that receives the most sunlight thruout your day (JUST LIKE A SOLAR PANEL)... the water that flows from your pool/tub travels all thruout your massive coil (or several coils, or an oval, or however you’d like to design it) where it gets baked by the sun... Once it completes the maze, it finds its way back into the tub!! If you’re skeptical, I’ll blow your mind... I tried this for a 15’ above ground pool that my ex-wife setup for the kids at her place... The water was always BONE CRACKING COLD and the money & effort she put into it was being wasted by the day.... Despite her DEMANDING I DO NOT DO THIS, I of course DID IT and the FAHRENHEIT TEMPERATURE of this water AS IT LEFT THE TUBING SYSTEM was 156°....... Yes... you heard me..... that was 156 D E G R E E S..... FAHRENHEIT..... 😳 OBVIOUSLY I had very little to do with it after the installation (just like literally everything else she uses me or takes my cash for) so I can’t testify to it’s lasting effects... The only tests I conducted THAT DAY were temperatures WITHIN the coil BOX I made (forgot to mention that placing your coil in a shallow, sturdy, DIY “picture frame” style box is a must) which I quite cleverly rigged to the roof of a large shed nearby... I struggled with whether or not to put a CLEAR glass over it, a FRESNEL (enhancing) glass, NO glass, etc... But further research after the fact SEEMED to suggest that a SEALED, internally BLACKED OUT, box w/ a standard clear plexiglass top was best because there was some issue with other methods that I’m not remembering... While the 156° RAPIDLY decreases as it mixes in with 6,000 GALLONS of glorious NJ TAP WATER, I’m quite confident that this MUCH SMALLER, better maintained, and COVERED hot tub application would actually benefit tremendously from my solar idea... Again, there are obviously details im forced to scurry past (such as the pump comment above - or HOW you’d use THE SUN to even POWER THAT PUMP - and so on), BUT seeing as how you have nearly 2 MILLION subs and I don’t even have a channel... I’m beginning to feel like perhaps I’ve explained this TOO much and that it was silly to think you’d need to reach out for additional info... lol 😬 my bad, oops! LASTLY - I have several motors, pumps, heating elements that I’ve SALVAGED at ZERO COST that I’ve been fiddling with - Just before watching your video, I was scraping bubbled up paint & mildly rusted metal from within a HEATING ELEMENT I took out of a perfectly good INTEX Hot Tub control unit that I can’t imagine NOT WORKING for you... I’m not sure why, but in my local area alone, on 2 separate evening, I was able to collect FOUR of these units - WEIRD since they’re NOT CHEAP TO BUY - But yes, 4 fully intact (i believe) units with LIKE NEW CONDITION internals that I recently began stripping down to learn how they work and see what fun toys hide inside!!! This heating element is quite interesting. It’s basically a “sandwich” holding an electric heating plate inside it w/ 4 leads on one end (appears to be for TEMP CHANGES)... The entire unit is 8” x 3.5” x 2.5” and there are spaces on either side of the heat plate for water to pass over it... Then there are molded plastic “end caps” that are VERY SECURELY screwed on each end which have the IN/OUT pipe leads and I believe 1 has a heat sensor inside plus there’s another heat sensor on the metal body outside (measurements DID NOT include these end caps, but they’re maybe 2” each added to the length of 8”) If this can heat an intex tub, it can heat your tubs... I’d be MORE THAN HAPPY to send you one of these bad boys so I can see how you implement it & as a thank you for what you do to inspire wannabe makers like me!! Just let me know using the email info above. Take care and keep going with this hard work you do!

[@allaboutrap1]

[@humblehombre9904]

I would not recommend a cloth, absorbent material underneath, as this will soak up water and rot your deck. Also massive mold will grow under hot water. You should use a closed cell foam which is used for underlay for flooring, built up to desired thickness.

[@LordOfThePancakes]

Maybe I want my deck to soak up water… Not a bad idea seeing as it sits out in the sun 24/7. Since when is a little moisture so terrible?

[@humblehombre9904]

@@LordOfThePancakes it’s not temporary moisture, it’s the water that gets in, and stays. It WILL go black mold on you. Eventually the boards will give way on you. If there is an air way, that allows the thorough drying of the wood, then rot can be held at bay for years. However, the moisture stays causing the deadly black mould, and mushroom type fungus that literally eats the wood. The heat from the hot tub will condense moist air and cause damp. Closed cell foam will insulate between the differing heat, thus no condensate.

[@anonymousindividual7626]

Hopefully you reinforced for deck and foundation to support the weight of the tub, and you want the underlayment to breathe, not hold moisture/water, which is only going to rot the decking below the tub very quickly. Also, try having the hot end (positive flow) feed directly into the tub to prevent heat loss. Insulating the walls would also help drastically hold the heat. Great build!

I built one using a metal tank like yours. Painted the inside blue and used a summer-fun pool filer cut in the side. it lasted about 5 yrs ,but the chlorine finally ate up the tank. It looked great and worked well. I also used an external pump from Harbor Freight to heat by running hosepipe through a solar greenhouse type deal . It worked OK, but never got really hot.I should of developed it some more I'm going to try again using a black 300 gallon Rubbermaid tub from tractor supply.Oh yeah I had a waterfall on my first one by using a small pond from Lowe's

[@landomilknhoney]

You might think twice about that poly tub, hot water destroys the polymer. You'll end up with black skin, black water and won't want to dump it on the ground.

[@siennastone5009]

I have a fabulous LP heater made Chofu. Been using it for about 10 yrs. Same idea w/ stock tank except I drilled 2 holes in the tank. The heater thermo syphons (circulates) the water. You just need a paddle to stir it up. Water is filtered through 2 sediment filters. Set it on a round hot tub cover for ground insulation then got 1” rigid insulation and scored it so it could be fitted around the tank. Got some dark green marine upolstery and covered it. Found a used round rigid hot tub lid. Has a timer. Runs about 7 gallons a month in winter (northern Ca). I don’t know if they make it anymore.

[@sixthangel9716]

I love it. Such a great and simple idea.

[@adam.g]

Cool idea, but with the shower head so high up, you will be losing a lot of heat as it heats the air and evaporates. Have the hose feed directly into the tub.

Looks epic!. just a suggestion - if you have the hot water go directly into the tub rather than using the shower head the water will be hotter, as you are losing heat from the water when using the shower head as it hits the air and cools a little before hitting the rest of the water in the tub 😊

[@tmbrye2]

I was thinking the same thing. I'd also add to this and say make sure the water you are adding is being added at the bottom of the tank since hot water rises if you add it to the top the hottest water is cooling down the fastest.

I use a similar set up as yours on some off grid property in SW Missouri . I have the Joolca set up as well and use that for my shower and dish washing - it is a great set up. I made a berm around and underneath the tub using rocks (we have tons of them around here) and a simple mortar mix. This gives it some insulation and on sunny days the rocks heat up

[@DustyKorpse]

Interesting build, very plug and play. Looking forward to the Cedar build.

[@tkskagen]

Chris Nicolson, I ment!

[@kbc1883]

I own the whole Joolca system and run it off a Goal Zero Yeti as my main shower and hot water sink in an off grid scenario, using a 150 gal stock tank as a bath tub for occasional soaks. I would not buy it just for use in this type of temporary hot tub set up because of cost. As you say, this is not a long term hot tub solution as letting the unfiltered, untreated water sit in the stock tank would get gross. But if you’ll get use out of the Joolca system while camping, at festivals, for everyday use like my situation, then this is a nice additional way to use it.

[@wtfu812omg]

That’s pretty genius . I would just adhere treated cedar planks with stain around outside of tub for aesthetics secured by glue and rope strapping or something. Maybe line the top of tub with thickest cut pool noodles you can find. Still trying to figure out how to filtrate it without having to drill into it and set up yet another contraption. Maybe line the inside with some big rubber sheet just to avoid the uncomfortable aluminum interior

[@FatalitY57xD]

AMAZING!

[@dinobuddy]

It will heat MUCH more efficiently if you drop the head directly into the water. If you spray it, the water that reaches the tub will be significantly cooler from it what it is at the nozzle because of evaporative cooling. Which reminds me, you might find some really neat applications for evaporative cooling in your Joshua Tree projects. (Evaporative coolers get pretty manky and gross, but the principle of their operation is fascinating).

[@Tpearson2002]

Im not sure of the pressure needed but adding a sealed through wall interconnect at the bottom of the tub to connect a hose to the propane heater then another hose that connects to a similar through wall connection at the top could be done without a pump. The pressure from gravity pushing on the water may be enough pressure to push it through the heater. If not adding a pump would be just as easy with a cleaner look. Possibly an electric water pump/heater would be better too depending on cost.

[@grahamulax]

OK I love this transfer pump idea! How much propane does it take to say heat that whole tub? Probably way cheaper than electric which my friends have and their bill was.....scary haha.

Hello, the recirculation idea does not work - we tried it. The Joolca has a safety feature that cuts off the heater when the output water goes above 124 F. The heater is designed to heat cold water, so once your input is over 80F the heater will get too hot even on the very lowest setting. You're limited to heating the water as you fill the tub, and then soaking until it gets cool.

[@civic2004racer]

Thanks for this, Ben! This was my concern with buying this system, as many pumps cannot handle too hot of an input and will shut down to cool off. Appreciate you sharing! Any other ideas to combat this problem?

@@civic2004racer no, you just run the water hot and then soak until it cools. In our 110 gallon tub we can run 110 degree water and soak for well over an hour before it cools too much. If you want to recirculate you’ll probably need a heater designed for hot tubs.

If it were me, I'd hook up my own 12v circulation pump that's sized right for the job and pumps enough water to make the water heater happy- hook up the hoses, adapt them as needed. I would replace the DC battery supply in the water heater with a dc-dc buck converter board (cheap on ebay) and set the output voltage to 3v, that way D batteries are no longer in the equation and the water heater runs now on 12v dc. I'd add an in-line 12vdc digital thermostat (they're cheap on ebay) and run the temp probe sensor into the tub. When desired set temperature is reached, power can be cut from the 12v going to the pump. This stop the heater. When water temp drops, the pump turns back on, heater fires back up, it's self maintained.

Why use a propane water heater? Coil 25 ft of 5/8"black drip line tubing onto a 4x5 sheet of plywood. Attach one end to a 12 volt submersible sump pump available on Amazon. The other end dangels in the tub. The pump is powered by a solar panel from, also from Amazon. Both the recirculation panel and the solar panel could hang from the wooden fence behind the tub. There are 12 volt pumps that can circulate 500 gals per hour depending on the size of the solar panel. 100% eco friendly and no burning of hydrocarbons. Probably cost $250. Never needs service. As soon as the panel catches the sun's rays, the pump starts circulating the water through the black heating coil.
