Question: How high of a temperature will it heat the water?
Document: I originally bought this heater to replace an old style on and off heater which failed after about 15 years.This heater was much better at regulating the temperature than the old one. It keeps the bed the same temperature.That is, until it failed. I bought it less than 8 months ago, and it can no longer heat the bed over 80 degrees.Having the heater for your waterbed fail is a huge inconvenience.
This water bed heater worked as it should, we never had a problem with it. The heat range was excellent.
That's fine if your house isn't chilly, but when it is the heater warms to the set temperature and then turns off. The chilliness of the room cools the water enough for the heater to come back on and thus the heater continues to turn off and on several times per second indefinitely. The only way to stop it is to turn the heater off or change the desired temperature a couple degrees and once it reaches the new setting you have to change it again.
Good delivery time. It appears this unit takes longer to heat the initial fill on a water bed than an older prior water bed heater we had.
Winter-cold water, not a good combination. When the heat goes out on your bed, you want fast delivery service. This was it. Pretty easy to replace, minus the water. It did take some time to get toasty- but that's life. Good delivery rate. I am very satasifed with this product. thank you
This unit works great. Keeps the bed a steady temperature. Definitely a good buy for the price. It installs just like any other heater.
I have the Thermal Guardian Touch Temp Digital Waterbed Heater. The Product Details for this product don't tell you which model this is and there isn't a close-up for the heater control so you can see what the model is or how you will control the temperature. My heater works well, except for one thing. My house is old and has very little insulation, so it tends to be chilly in the winter.
Heat Is Great Constructed So much better then my original heater i got with my bed. Ive very well pleased with it
We replaced our old waterbed heater with this one and realized that it was exactly the same model. I think nine years is a pretty reasonable longevity for a heater. We ordered it on 12/24. Even with Christmas on a weekday and a Sunday before that, it still arrived on 12/29! We installed it yesterday (I had to thaw out the hose) and it is almost up to heat already. Well done!
This water bed heater works well with a queen size bed. It is very reasonable in the pricing as well.
Answer: Most waterbed thermostats I've seen will go as high as a hundred degrees.
