Like all thermostatically controled devises, if you have it set at 79 deg or lower and your tank is 80, it should not turn on. Of course you may have a calibration issue by a couple of degrees (set at 78 may actually be 80). Unplugging it would not help unless it is malfunctioning and still turning on above its setpoint. In that case, replace it. Actually, I think it could be more harmfull if your house cools off one night and the heater is unplugged....TailorO said:... should i unplug all my heaters? ....
Thats fine, do they have LEDs that tell you they are turning "ON", if so are they?TailorO said:right now it is 10am and about 85 degrees in my house....as for the thermostat in the heaters, only one of my heaters has one that you can set at a specific degree. the other two just have a dial that reads high and low
