Propylene Glycol Antifreeze/Non-Toxic Antifreeze to keep the hot tub’s pipes from freezing during the winter. This is a very specific type of antifreeze that is sold for hot tubs. Do not use the type that you would use for your vehicle as it is toxic.
I love the irony in the naming here!The best propylene glycol antifreeze on Amazon is from Engine Ice.
I have a hot tub and have been thinking about how I could use it as "storage" to dump my excess solar energy during the day, instead of net metering or storing it in a battery.
All you need is a line blower and some antifreeze, both of which should cost about the same amount as a single opening or closing. It's really easy to close a spa yourself. You could probably get by with something smaller and cheaper if it's only for a spa as well. They also come up on eBay periodically, especially mid-season (middle of winter, or middle of summer).We paid "pro's" last year to winterize it. I could have done a better job. They didn't drain the ozonator/UV box so it froze and broke. Then they couldn't come up with replacement part, even though they're the ones who installed it (it was a replacement/upgrade when the original ozonator failed), and I wasn't even trying to make them pay for it.
That'll help a lot. I've been adding 2 inch pink panther FOAMULAR board foam.I have a thick cover, but not a floating one. I added a lot of insulation between the fiberglass and the wall of the hot tub. Just went to Home Depot and picked up some rolled up home insulation.
I came to the same conclusion in my testing. mine is ~1200 watts but I consider it more "supplemental power" kinda keeping it the same temp it already is atThis made the heater more manageable at 1.5kw.
So here is my plan:

I'm going to add a section of plumbing that inserts the NG heater into the hot tub existing plumbing.
yes please do! I would be very interested to see how that goes for you and what your final setup looks likeIf I get around to this project I'll try and remember to post up a thread here.
My favorite is when my hair is frozen and I'm in the hot tub.And this idea of draining it for the winter I don't get. I think winter is the best time to use a hot tub.
yep I love that, also jumping in the snow and then running back in the hot tubs.I think the coldest I used the hot tub was 17 Fahrenheit, your hair would freeze if you were not wearing a hat. Putting dish soap in there was fun, 2 to 3 feet of frozen suds. Getting too old for that adventure.
crack just from being empty? that's a new one, what commission percentage do the sales guys get there?I have had a hot tub for 10 years now bought it used from a friend who lost their house to foreclosure and divorce. Didn't pay much for it since then I have gone through 3 control modules and a new pump from Acura Spa in Riverside, CA. It's a power hog put a amp meter on the wire watch it pull 50 amps at 240V. Even my hot water heater doesn't pull more then 20 amps. I turn it down to 80F we heat it up on the days we want to use it. Sometimes the clock gets flipped so it's heating during peak hours I'm getting a demand charge now in the winter.
We haven't even filed it yet this year been so warm here in AZ we still hitting 80's. I might fill it we do like using it when it gets down into the 40F degrees. Most of the year it stays drained spa store told me it might cause it to crack not keeping it filled if that happens ill just trash it. We been draining it for at least 5 years now I open the connection to the pump drain the water out of the lines.
That is what he was saying because summer gets to 119F here it being drained might cause it to leak because dries out. I haven't had that issue with it we had a pump go out and the control board died 3 times. I'm not sinking any more money into it if it dies give it away first who hauls it away. Lots of them in FB marketplace, or CL for free all the time here. People buy them don't realize how much work it is keeping the chemicals perfect and draining refilling. They leave them full of nasty water all summer turn green eventually just want it gone. The cost to have it wired into the house is also not cheap I did it myself I know a co-worker who spent $2500 for a contractor to run wire underground. He put in a 16-person hot tub cost him almost $20k I told him he was nuts in AZ just sit in the pool 92F water in the summer.crack just from being empty? that's a new one, what commission percentage do the sales guys get there?
It'd crack from your extreme temps etc way before just magically sitting empty
