can it be used to heat a hot tub when you are not in it?

I use IT to warm up an outdoor jacuzzi and it works fine. Depending on the size of your hot tub it may take a while to heat it. Since this heater has no temperature control you have to watch it from time to time.

Besides the fact that the thing would have to be suspended so the top of the handle doesn't get wet it would take a very long time to heat a body of water that large. Heating a dishpan's worth to comfort level takes about 20 min. Not something I would want to leave alone for hours and hours.

I don't see why not. Our spa is attached although we don't heat it, so not absolutely sure.

Yes you can, it doesn't get hot enough, the heat radiates from the bottom and it is just a nice warm heat, not hot.

The manufacturer states it ca be used as a booster to the existing hot water supply. Hope this helps.

Yes, I guess it would heat up soup. Not sure how it would work and if you would need to put at least a small amount of water in the reservoir without damaging the unit.

If you have never used it with chemicals int he water, I would think so but it will get so hot you can't stand it. It would have to be unplugged by someone else. Something else would work better.

I bought this for the exact same purpose. and the answer is 'no'. You can't get it to stay close enough to the tub and the heat it produces is not suitable for under tank warmth ie the cable is thin and the heat localized .also the cable is only heated for a relatively short portion of its entire length. I ended up using heat tape with good results.

Sure. I don't see why not. It appears to be water tight. You will have to reheat it every 8 hours or so.

We've used ours to heat a tub from 70 degrees to about 110 in an afternoon, so it should definitely help keep an existing tub hot. Not sure I'd leave it plugged in while I was in the water, but that's just me worrying about electricity.

Probably. I never tried to just heat water and I have since given it away. Sorry

Yes. Think of the water in the tub as hot soup. You blow on the hot soup to cool it down. Air being blown through the water in the tub will cool it down. The heater will help maintain a comfortably warm bath.

I don't think so. A hot tub has too much water turbulence which would keep it in the on position.

It never seems to stop heating so should be no problem for your tub. And yes you can use a garden hose with an adaptor

NO. It takes a long time to heat it up and it cools off too quickly. You have to use it when it is warm weather.

Unfortunately no, but you can just as easily put cold water in it and run it without worrying that its gonna heat up. The heating thing only keeps hot water warm for a short period because its not meant to actually heat up the water.

You could, but the heating element does not heat up the water very hot (in my experience).

This product was designed to heat while submerged in water. It is always risky to use a product in a manner other than how the manufacturer intended. I recommend looking up and contacting the manufacturer directly to get an answer to that question.
