Get in some hot water
Without a waterbed heater, the temperature of the water in a waterbed would be room temperature, which is around 76 degrees Fahrenheit. Such a temperature might not seem that chilly, but when you're sleeping on water, it is. A waterbed actually pulls the heat from out of your body, dispersing it in the water.
Even in the summertime, you can get quite cold sleeping in an unheated waterbed. Additionally, the heat provided by a waterbed heater prolongs the life of your waterbed, by keeping the vinyl a constant temperature.
Most high-end waterbed heaters will feature automatic temperature regulation, which keeps the water at a constant, comfortable temperature. These modern waterbed heaters are known to keep a constant temperature with one-tenth of a degree or better!
Of course, waterbed heaters let you dial in your preferred temperature within a certain range, so you can enjoy a dynamic comfort level throughout the summer and winter. Even better, it only takes a matter of seconds for waterbed heaters to reach a certain temperature, so you won't have to wait long for your bed to be toasty. Most people prefer a heater to be set at 86 degrees.
Those concerned about energy costs can rest easy. Waterbed heaters are specifically designed with low energy consumption in mind. Most models use 150 to 400 watts of power, which translates to an annual energy cost of $100 to $200, a number significantly lower than the heaters of the past. Today's heaters are also manufactured to give off the absolute lowest magnetic field rating possible.
Although some waterbed heaters are sold with waterbeds by certain manufacturers, many people prefer to buy their waterbed heaters separately. The reason for this is that the majority of aftermarket waterbed heaters are of higher quality than regular ones. Most consumer waterbed heaters offer a variety of heating options, which many people find useful.
It's also important to check the safety features of a waterbed heater. The unit should be resistant to power spikes and surges and offer protection from overheating. By just keeping the aforementioned features in mind, you should have no problem finding a well-performing, inexpensive waterbed heater.
