Oil Drum Pool Heater That Works Amazingly! 

Props to you big dog, that's some super dad ingenuity. Seeing the kids happy make it all worth the R&D.

I would love to see a 55 gallon drum rocket stove version of this. The manifold you made is definitely the missing link for DYI pool heaters.

I have been watching so many of these videos. I just got a pool and hate when the water is super cold. Great Idea with the heater by far the best in barrel one i have seen to get the correct flow great work

awesome! 4 of the 1/2" lines is the cross section area of a 1" line. you'd need 16 1/2" lines to get the cross section area of a 2" line. i want to build something like this.

Great job. I just bought a stainless steel barrel and ordered a barrel stove kit. I am looking to address the problem of the manifold/piping sweating inside, eventually creating a thick coating of carbon on the pipes. This dramatically reduces the efficiency. Piping the outside of the barrel would be less efficient but still work however I don’t want it to look like crap in the yard, hence the stainless steel drum. It will he interesting and I will incorporate your tip on the manifold / multi pipe and manifold design.

You've got a bottle neck in your system my guy. Area of a circle using diameter: A=.25πd^2 So the area of a 2" line is 3.14 Area of a .5" line is .2 So 3.14/.2 = 15.7. Round up to 16. You'll need 16 half inch lines to equal the same cross sectional area as a 2" line.

This is exactly what I was looking for! Really curious on how you constructed that manifold. Awesome job man.

Just letting you know; I am going to "steal" your idea ;)

The big point missed here is not flow rate, but "delta T". With headers and multiple lines in parallel against the hot surface, all the water entering the header is at the pool temp. The amount of heat transferred will be greater than having only one entrance and one path around the heat source having a diminishing temp difference.

Great video. I am trying to build something similar, but not sure I have the skills to tackle that manifold idea you constructed. I did have a question though, how did you connect the blue pool hose to the manifold. I am probably going to use 1-1/4" pool hose or a garden hose but I cant figure out how to get it all connected to my pump. Thanks

Can you put a list of the items used in the description please?

Very cool 💯💯💯👏👍

What is your gallon per minute output? If could I achieve the same GPM with a 3/4 heating pipe would I still need to run in parallel (like yours)or can I do just one pipe? I have a big pool and would prefer high flow rate with lower output temp. in order to change the pool water more quickly.

How long before the stainless pipe disintegrated?

This is pretty cool! Could you build one for sale?

Great video! Can you use copper pipe instead? And the "manifold"...how did you make that? (Thanks!)

What did you use to seal the fittings in the pipe for the manifold? Or did you have issues with leaks there?

how did you make the adapters?

Hi will it work for 45000l

NIce vid! but did you notice it was leaking a bit?

Working but as you can see all the heat is lost in the sky. If you can add some metalic parts on the top to grab this lost heat that would be nice. Look at this one : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Iz2es9EAVFM.html

why don't you use electricity ? it creates much less mess and easy .
