also wondering what interference is since you mentioned it....
Have you ever been a room with a PA system and a bad ground? The wiring will pickup all sorts of EM signals that are floating around. While this isn't going to be an issue for the flexwatt it could mess with a sensitive thermostat.

All I meant with "especially" is that it is more likely to happen if you don't know what you are doing. But it can happen to anyone. I've been through training and have certification to solder circuit board for military/medical use (class 3 boards) and solder sensitive components almost everyday at work... and even still from time to time I get a bad joint.
