A recent heater disaster thread in the polypterid section prompts me to ask this question:
Are there backup thermostats available? I'm talking about a plug-in thermostat with a temperature probe that I can plug my heater into and set a couple degrees higher than the heater, so that if the heater's thermostat fails, the backup thermostat keeps it from cooking the tank.
I would spend up to $25 on one, before building it myself.

Unfortunately, quality temperature control is not cheap. I'm not real good w/ DIY so I can't comment. I can tell you that this setup has worked well for me for a little over 4 years & counting.
