Calesco Full Watt Hard Side Waterbed Heater

I've had this particular heater for 4 years now and it holds its heat well. When filling my mattress in the winter it was icy cold water from our outdoor faucet. Took 3 nights (on medium setting) to feel the warmth. That's typical. I'm 63 and have used a waterbed for almost 50 yrs. This heater is the only choice for me. It's the only kind I've used all along. I usually set it one notch beyond medium in the winter and one notch below medium for summer. I have no complaints. If you want the best heater this is it. Don't waste time, or money, on anything else.

I had to replace the heater on my waterbed and was interested in a quality replacement. This heater is wired, rather than aluminum strips, which should provide durability. So I won't have to be worried about a replacement for a good long while. Also, it was able to heat up a queen sized bed in about 24 hours. The only downside is that the temperature control is a simple resistance based unit rather than a digital one. But at the end of the day, with some slight adjustments, I have the temperature where I want it. All-in-all a great value for the money.

I had a unit that functioned well for 30 years and replaced it only because I was replacing everything and assumed I should replace it, as well -- yet it was working perfectly. Unfortunately, the unit I replaced it with (recommended here but not solid-state) failed periodically, leaving me severely chilled a number of times, in spite of all being properly plugged in, etc.So I then purchased this one, as all of the connections are solid -- no plugging and unplugging -- in hopes that would solve the problem I had with the just-purchased unit -- and indeed it has. As some reviewers have noted, the temperature setting is based on a scale of L-M-H with points between and not degree notations. Nonetheless, as with degree settings, once you know where you like it, that's not a problem, and it has held my settings (different for warm weather, obviously) beautifully and without fail so far.So I have come to trust it .... at least as much as a person can who spent time with a prior new heater that failed miserably (though lighting up as if to heat) periodically. So after 3 years, I feel I can honestly recommend this heater. :-)

Okay when I open package up, I thought the heating element looked small for my queen size waterbed. I was surprised to see it didn't have a separate temperature sensor probe. I think because it didn't have the temp probe away from the pad, is the main reason for the uneven heating and the bad reviews. Also not having a numerical numbers to set the temperature doesn't help the reviews either. Does it work, yes It does. To compensate for the uneven heating, I will push down on the mattress several times to get the water inside the mattress to circulate around. Not having numbers on the temperature control dial is no biggie for me..

I did considerable research about waterbed heaters before selecting this product, after my old one lasted for years, and am really pleased with the Calesco Heater. While it's true its dial does not have all the bells & whistles of other products, the heater works like a dream and has much better reports of longer product life.

This is my ninth heater in 30 years. Shipped flat! Most heaters I've gotten have been rolled up, and I have to flatten them.All the instructions are printed right on the device. But it also comes with a booklet. Looking at it, you can see the wiring of the heating element. Unlike most heaters, the thermostat is integrated into the device.The control gives a temperature range of High, Medium, Low -- I'll need to look into their documentation to see what that means. The LED on the control is very tiny -- if you are looking at it, you can see if it's on or off. It doesn't illuminate the room.There is so much elegance in this design that I felt slightly guilty about hiding it under my mattress.Highly recommended.

WOW! Super fast delivery, we've had waterbeds well over 30 years and always used the heater with the metal probe. So when I came across this type I said, let's try it. Were glad we did. The unit is well made and not flimsy like some others, heats our Qu. Size quicker than most after cold refill. And does its job. Like they say just set it & forget it! They even put in a free bottle of cond. Extra with it. Just can't beat it on price, super fast deliver, and performance. Great co. To deal with. Thanks. Bill in W.V. Update 3/18 still working great, just wanted to tell ya if your on the fence. Thanks, Update 7/19 still working Great, Thanks

Just put it in, it heats. No test of time yet.
