I guess we seem to agree to disagree. Actually I believe quite the opposite is true. With a heater that is too small the heater will be on for longer periods of time. This causes the high current to run for longer periods of time eventually causing distortion, and corrosion at the contacts, and burning out the heating element faster. With the 5 watts/gallon rule of thumb, or just plain using a larger heater than required, the unit will cycle a what is considered a normal interval and function for longer before any maintenance, or disposal, is required.
