I posted this question before I registered. Here's an amplified version of the question: I have an electric floor mat heater that gets too hot. I've found a good dimming device made primarily for incandescent lights, one that uses a triac unit for reducing the electric output. Would this work well for my heater?
No a switch just opens and closes a circuit. A switch can be replaced by a dimmer switch. The dimmer switch will fit in the same enclosure that the switch is removed from.
It was not designed to be used with a dimmer switch. You must have a halogen designed for use with a dimmer or it will not work.
Yes
No
Look on the carton that the dimmer comes in. On the label there will be a list of lamp types that the dimmer can be used on along with the maximum wattage that the dimmer can control.
Compact florescent do not dim. They are all or nothing. You can use them where you have a dimmer switch. They will come on from about half way to full on. Dimmer switches don't like them and the switch will burn out faster.
You cannot use most fluorescent lights with a dimmer. Just about any incandescent bulb WILL work with a dimmer. Occasionally, when a halogen bulb burns out, it will destroy a dimmer switch but halogen bulbs are considered incandescent and other than that little problem they work well with a dimmer.
No, the voltage rating of the switch is too low.
Probably not, since a volume control switch is designed for extremely low current measured in fractions of a watt, while a dimmer switch is typically capable of handling several hundred watts.
Domestic coil in boiler better than electric water heater.
The dash light dimmer switch is worn out. You need to replace it.
There is no need to bypass it. Just do not use it.
