Safe and Reliable

Calesco Norells has been in the heater making business for 30 years, 20 of them as a leading supplier of waterbed heaters to the European market, as well as having become a world leader by supplying over 20 million heaters per year to the Automotive Industry across the globe.

Easy Installation

Install the heater pad right side up, under the safety liner. Remove wrinkles in the mattress and liner over the heater pad. Locate the heater pad so that blankets or sheets will not be tucked in over the heater pad. Place the heater pad on a firm flat surface, not over cracks or across the gap between deck boards or split foundation bases. *See Installation and Use Instructions.

Easy to use

You can check or change the temperature setting on your control box even in the middle of the night. When your Calesco heater is creating warmth, a small diode is lit., telling you the unit is in heating mode. By turning the knob, you can adjust the temperature setting. The small control unit is integrated with the heater making it more watertight, and there are no extra cords to worry about or try to reach in the dark. ONE PLUG AND YOU’RE SNUG!

Temperature Selection

Once you select and set the Calesco electronic thermostat, the Control Unit maintains the water temperature within ±1˚ F, in normal room temp, to keep you cozy and comfortable until you decide to change it. The Control Unit monitors your comfort level and maintains the life of your mattress. Our solid state construction prevents those “clicking” noises so irritating in old mechanical style heaters. And with no moving parts in the temperature control unit, the expected lifetime and accuracy is greater than most competition models.

Patented Circuit Design

The Calesco waterbed heater, with its patented circuit design and generous polyester insulation operates with one of the lowest electromagnetic fi elds available on the market today.

Highest International Standards

Both the heater and control unit have been designed to UL 1445 standards and certifi ed by ETL for USA and Canada. Calesco Foil adheres to ISO 9000: 2000 standards to ensure quality is maintained in production and testing of our products.

Control Unit

The smaller design of the solid state Calesco control unit allows for passage through most waterbed frame openings with ease. Our unique control system is designed for greater comfort and lower energy consumption. The control unit is designed to resist electrical spikes up to 1500V. Note: The control unit does generate some heat and should NOT BE LEFT in contact with the mattress. *See Installation and Use Instructions.

Longer Life

The patented design of the Calesco Waterbed Heater maintains low, even surface temperature and low thermal expansion -prolonging the life of the heater and the mattress. Calesco heating elements have been tested according to UL 1445 standards and CSA C22.2 No. 200 standards.

Overheat Protection

Calesco elements are protected against overheating by an automatic cut-off which is actuated by abnormal circumstances. PLEASE NOTE THAT DURING EMPTYING OR FILLING THE WATERBED, THE ELEMENT MUST BE UN-PLUGGED.
