Solar system to warm water in outdoor bath tub away from the water source

[PNPmacnab]

If you can afford that much battery you'd probably have something better than a rubber tub. I use my hot tub sporadically and let it drop to 80F when not being used. Mornings when I am going to use ,it will be turned on when I wake up in the night. I have this down to a science. With a 4,000W heating element, it is 4 degrees an hour to warm up. That is a lot of storage for a couple of days.

The problem is the sun doesn't shine every day so there will be no warm water on cloudy days using only solar.

Get a small 12V panel, a little 12V pump, and a roll of black plastic pipe.

If he's got a circulation pump with it he could probably tap into one of the returns and only need a coil of black tubing.

It must be a tiny Jacuzzi if you expect that heater to be effective. Maybe your water is already warm and you just need a small boost? It will probably only add 2-3 degrees an hour at best but I am purely guessing because I have no idea how many gallons you are heating and what the temperature rise needs to be. Might be easier to carry 5-gallon pails of hot water from the house.

So why do you need 1,000W ? Is this a bird bath or tub for cattle water. I heat water with solar and happy with fairly low power, it is most of day. Electronically this is neither complicated or expensive and doesn't need batteries. Unfortunately there are no cheap products to do this.

It is a blowup Jacuzzi so I bought a portable heater. What solar device you use to heat water?

So as Mike stated you will need an inverter and they require a battery. So you system will include solar panels, charge controller, battery system and inverter.

That may cost you a pretty penny for a hot bath. You might be better off getting an inverter type generator and just run it long enough to heat the water. Then shut it down and soak.

That plug in immersion heater is only rated to run on AC. Put it on DC and the thermostat contacts will weld shut and the thing will boil dry.

I am looking to run this https://amzn.to/3h9Unv5 1000 watt immersion heater to warm the water for an hour or so. What would you experts suggest if I am looking for an off grid solution? Since power source is far from my house and I don't wanna deal with permits and such so I was looking for a portable solar panel system that can run without batteries and provide power to this device for an hour during the day time.

Appreciate the help.
