Does this work in a covered hot tub that is always fairly warm?

I have had one of these floating in my swimming pool throughout both hot and cold seasons, including the hot summers of Georgia. It has worked perfectly, sending its signal up to our kitchen on a windowsill inside the house. ...Steve on Jekyll Island

The cover is meant to hold heat in. You can't expect it to effectively heat your pool although with it in place on a sunny day it will add some heat if the circulating pump is activated.

I am wondering if one of these is enough to work in a small hot tub? I am looking for a hot tub that is around 250 gallons. 1. Would I need to use 2 of these or is one sufficient? and 2. would I use it all the time or periodically?

No. It does not get as warm as a regular (human) heating pad, however, so this is not a problem. My frail old dog loves it. I put it under a blanket on top of her dog bed. A great product!

It will work, just not as well. The biggest robber of heat from your pool is actually the wind, not the outside temperature. So 4 feet of exposed area is not going to completely negate having the cover, but also not as good as it could be. Hope that helps.

I'm not sure. Maybe it will work better than in an actual hot tub. I have had mine for less than a year and it has been getting stuck on the same temperature for quite some time now and the other day I was going to reset the floating part and when I unscrewed it the gasket stretched out of shape which means it is no good now without it.

I am not sure, but it worked in a 500 gallon 20 year old hot tub, very quickly.

Yes it does. I love my new Comfort Zone heater. Although not an outdoor product, I use it on my back covered patio and it keeps me toasty warm. As a matter of fact, there have been when I've had to turn the temp down to low since it is so effective.

It was designed to fit a wide range of Spa's. It has a low power consumption and will not be good enough for large spas though. Another point is that it only maintains the temp where it is turned on at. It will not heat the water hotter. Put it in our jacuzzi bathtub and its great. Keeps the water temp just where we want it for an hour or more. For this it is perfect.

I've used this in a small bathroom and it works well. It may make the bathroom feel quite warm. I had a leak in my bathroom that I was trying to keep dry until I could get it repaired.

Maybe a little, but if you leave it in the sun the water will definitely get warm. It's thin and meant to be very lightweight, so I wouldn't say insulation is it's primary purpose.

I use it in a pool, but the same applies to the hot tub as a pool. I would say it works.

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.

My pool is cleaner than without the cover; I use the same amount of chemicals as before. It is sparkling. However, I live at the beach and the pool doesn't get terribly warm - 6-7 degrees more than without it. Been using a cover for over 15 years. Wouldn't be without it.

This item was for my mom and she doesn't have jets in her tub. If you have jets on the back of your tub, no, you wouldn't feel them. Next to the seat on the sides of the tub would be covered too from the side panels, but from mid tub to the feet you would. It does recline to about 45°. It truly has been a blessing for my dad because he doesn't have to lift her in and out of the tub any more. Would most definitely recommend.

No it gets pretty warm when you plug it in and that's how it's designed to evaluate the moisture. It is not meant to be plugged in all the time.
