There is a concern that we have seen with some surge suppressors lately. Many surge suppressors use a capacitor type device to soak up the surges in the AC lines. The problem is that some of these alter the natural AC sine wave that is necessary for any proportional thermostat to function properly. The result is the triac component found in all proportional thermostats is able to turn on but not always able to turn off causing the heating devices to stay on uncontrolled. This can be an immediate result or show up later in the suppressors life. Of course the flipside is without surge suppression the life of the thermostat is at risk with voltage spikes. Should you use a surge suppressor you may want to look for a higher quality one and monitor it during its first usage and confirm that things are working properly. Also surge suppressors are only good for a certain amount of time and you many want to change them out yearly.

It gets quite expensive. I use Tripp Lite Isobars on mine.
