InnoMaxThermal Guardian Quantum Solid State Waterbed Heater, Low Watt

Worked well for what I needed. I have a flotation waterbed and the guys who installed it said I didn't need a heater because of the pillow top. I've had that bed for about 17 years. One day I went to change the sheets and I noticed it was wet under the mattress. It covered every square inch of the liner. So I drained the bed as best as I could and dragged that mattress off the bed, thru the bedroom, down the hallway, thru the garage and out onto the driveway to drain the remaining water so I could throw it away. Must have weighed almost 200 lbs because I had no way to get all the water out. And thru all that dragging, there wasn't a single drop of water on the floor or anywhere on the mattress. There was nothing wrong with that mattress, but I couldn't reuse it because by then with all that tugging and pulling and dragging, I had completely ripped all the polyester inside the mattress to shreds. So I did some research and I think that wetness was due to condensation. We have really hot summers in Sacramento (over 100) and maybe it was the combo of the hot air and cold water that caused it. So, I bought this heater to regulate the temperature. I can't stand a hot waterbed so I have it set to 72. Now that it's cold at night (by Sac standards, low 40's ), I do notice the bed is warmer and not ice cold like it used to be. So I'm hoping I'm not going to have any more moisture issues some summertime. However, I had to MacGyver a board to put the heater on. My foundation has wooden slats and a lame cardboard top. Perhaps that's why the hot Sac air got to the mattress. No insulation. So with those wooden slats, there was sagging between each slat and you can't place the heater on that kind of surface. It needs to be completely flat. So I went to Home Depot and bought one of those Rubbermaid particleboard bookshelves because my only piece of scrap plywood wasn't long enough. I cut a section of the old waterbed mattress and wrapped that shelf with it so there wouldn't be any rough edges. Then I Gorilla taped it on. (Man, that is some AWESOME tape!) Then I put the heater on it and taped the corners of the heater where there are no wires in the carbon fiber, to the board so it wouldn't slip. I put the heater on top of the liner and then the mattress on top of the heater. Bob's my uncle. By the way, as long as you're reading this, let me give you a very helpful hint because I didn't discover this until after I filled up the new mattress with water. On those foundation mattresses, only fill up the mattress so it's even with the tops of the soft-side frame. I overfilled mine and ended up doing 3 separate draining sessions in an attempt to lower the level. I have it close, but it needs another one. Good luck.

I have been satisfied with all my purchases

Installation went well. We fill with cold water and the mattress temperature was up to 92 in two days.

I could have heated up a lot better.
