Thermal Guardian low-watt heater
Shallow fill waterbeds and normal fill single softside waterbeds require a smaller heater output than other types. With a lower output heater we can not only save on energy consumption, but increase the mattress's lifespan since it is exposed to a lower temperature. With time excessive heat will decrease the mattress's lifespan. The 125 watt output of the Thermal Guardian low-watt heater satisfies the heating requirements of these waterbeds without subjecting them to unwarranted heat. Similar to its high-watt cousin its controller has a separate receptacle for the heating pad, thereby making heater replacement easier in many instances.
