Nice work, I do want to point out that I'm still not sure about the heaters running all the time. I would expect them to be temperature controlled to some extendt They should only turn on when needed (temp. dips below a certain point) they would not be running at full power the entire time they are plugged in. If you are trying to keep your tank at 80 degrees and the ambient is 70, the heater will only need to turn on in short increments to keep the temperature stable, say when it begins to dip below 78 and it heats the tank back up to 81. It'd be a total long shot but I would figure it necessary to introduce a diversity factor in that equation. Assuming the the heater is only on say... 50% of the time?
Here's a spreadsheet I created to calculate electricty cost.
Anyone can change it and I can't lock the cells... So please only change numbers in blue. The rest of the cells are formulas... so any changes to black numbers will screw up the spreadsheet.
Good luck! My cost for one tank is $19.09 a month.
