DIY Solar Hot Tub

I decided to make a hot tub powered by a solar pump and 200ft of black hose. I used a 150 gallon stock tank. It works nice!
Things I used:
* Hot water heater 12V circulation pump ( amzn.to/3wBJNap )
* Rich Solar 100W Flexible Solar Panel ( amzn.to/3Osq7gc )
* Renogy 100W Flexible Solar Panel ( amzn.to/3nokl3d )
* Flat black paint ( amzn.to/3cwDX38 )
* 100ft Black 5/8inch hose ( amzn.to/3R4RhdU )
* 1500W Immersion back-up heater ( amzn.to/3CylnCz )
* 1inch ENT pipe ( www.homedepot.com/p/1-in-x-10... )
* Makerpipe connectors ( makerpipe.com/ )
* Owens Corning closed cell NGX ( www.homedepot.com/p/Owens-Cor... )
* 150 Gallon Rubbermaid stock tank ( amzn.to/3wCXeXB )

Thank you for sharing this! I have a stock tank pool with this exact stock tank and even in the height of summer, the water is uncomfortably cold until the late afternoon. I decided this year to try something similar with a black hose and am very happy to have come across your video.

Tru dat!

I always enjoy your videos. Thanks for working on this one. I was looking at solar water heater and saw a few experiments where a PV system could be more efficient. That could be nice to replace the electrode in the existing water heater and not have to worry about the expansion or contraction of the water. In you hot tub that wouldn’t be a problem since you don’t have a closed system. Wel … enough rambling. Good video and hope you guys are doing well.

You are so creative! Love it.

this is awesome !

Love it!

Would it be more effective, if not efficient, to employ a couple more solar panels to power the submersible heater, allowing you to not use the coils of black hose?

[@SerendipitySue]

You can do Solar Electric or Solar Therma hot waterl. I think solar thermal is a bit more efficient for low-end water heating applications (ie. pool), You would need 6-8 large solar panels to get 1000W for the immersion coil. Newer water heat pumps would be much better (www.renewableenergyworld.com/solar/solar-hot-water-which-is-better-pv-or-thermal/#gref )

@@SerendipitySue - My wife and I recently replaced our old hot water heater with a new model than includes a heat pump on top. Holy cow, are they efficient! Our electric bill dropped almost $40/mo. I can't wait to put enough solar on the roof that 90% of my hot water comes from powering that high-COP heat pump! :)

@@jasonbroom7147 I’m curious what brand/model you went with? I’ve also wondered if your heating bill goes up (since you are transferring heat from the area where your hot water system is to the hot water). Does the system have a condensation pump? I’m also curious if I could eliminate or reduce running dehumidifier in my basement?

@@SerendipitySue - Chris, we went with the Rheem Proterra. Our utility room is right off the garage, so not part of our conditioned space. When our furnace or air-source heat pump (HVAC) is running, that utility room is usually around 55 to 60 degrees, even on the coldest days. Also, our woodstove has a plenum tied into the HVAC hot air return, so we can "heat" our home and our hot water with propane, wood fire or the heat pump outside. No matter how that room is warmed up, it allows the smaller heat pump on the hot water heater to do its magic. The exhaust from the heat pump is ducted into our garage where it provides AC during the summer, although it does make the garage colder in the winter. The system requires a condensate drain, but if you install that then it dries the air somewhat. The Lithium Solar channel reviews all of this and he said the heat pump is too efficient at heating the hot water, so it doesn't run long enough or frequently enough, in most situations, to really be a dehumidifier.
