Easy to use You can check or change your control unit 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 heater making it more watertight, and there are no extra cords to worry about to try and reach in the dark. ONE PLUG, AND YOU’RE SNUG!

Our unique control unit is designed for greater comfort and lower energy consumption and is able to resist electrical spikes up to 1500V. Temperature Selection Once you set the thermostat the control unit maintains the water temperature within +/- 1ºF, in normal room temperature to keep you cozy and comfortable until you decide to change it.
