Water Bed (with heater, no cover)

Water bed heaters, although plugged in all the time, actually cycle on and off at a rate that depends on a number of factors. Energy use varies based on air temperature, consumer behavior (temperature settings and use of bedding), and bed characteristics, such as framing, depth, and insulation.

This calculator estimates that your water bed heater is only actually running 50% of the time.
