I stand corrected and thanks for the info, Mike! I keep killies so don't use heaters, but if I ever go back to tropicals, your method would be the safest. I was thinking the electricity bill would increase with my method, too.

The ideal heater would be on continually at a very low wattage replacing exactly as many BTUs as was being lost and never turning off. So a very small heater set to the target temperature you want and then a larger back up heater set a few degrees below the target temperature would be ideal.
