Some of our heaters can be wired to deliver different amounts of heat output or wattage. A multi-watt heater isn’t designed to provide more heat when you need it, it’s more about having a heater that is flexible and can work in different size rooms.

The big advantage is you can pick up a multi-watt heater at your local hardware store and it will work well in a bedroom, living room or even a bathroom. After all, picking the right wattage to heat your room is important.

We offer multi-watt baseboard heaters, ComPak Max, ComPak Bath and Register wall heaters. The heaters have multiple heating elements. By modifying the wiring, you can disable some elements which leads to the change in wattage.The changes need to be made before the multi-watt heater is installed in the wall.

It’s not as convenient as flipping a switch or pressing a button but it’s not too complicated if you have some help. That’s where we come in. We made a short video that will show you how to change the wattage on our multi-watt Register wall heater.

The process is actually pretty similar to what you would do on a multi-watt ComPak Bath heater. You have two wire leads that attach to two individual elements, disconnecting one means it wont power on. The rest is math. For instance, the RM162 heater has a 900 and 700 watt element. With both powered, it delivers 1600 watts of heat. If you disable the 700 watt element, you get 900 watts. If you disable the 900 watt element, you’ll get 700 watts.

If you have a multi-watt ComPak Max or baseboard heater, the process is a little different.

ComPak Max

ComPak Max multi-watt heater leads
The multi-watt ComPak Max heater has four leads that can be modified to change the wattage output of the heater.

The ComPak Max heaters are a bit more complicated with four leads to deal with. Each unit has the wiring diagram both on the heater and in the owner’s manual.

Baseboard Heaters

With the case of the multi-watt baseboard heater, which has a 2000- and 500-watt element, you need to cut a wire and attach a wire nut to disable one of the elements.

As always, you can check your owners manual for further details or contact us if you need more help.
