I hope this practical question is not OT and not too trivial for this forum. I am renting an apartment in a duplex with a shared water heater and dryer. Turns out, both water heater and the dryer are connected to my meter. The neighbors seem willing to pay their share for the past 6 months, only how to estimate their fair share?
I tried to leave the apartment for a couple of days and take a reading from the electric meter before and after. It appears that in these 48 hours, my meter changed by 10KWH, i.e. $5/day, with everything but the fridge off. Realistic? There are 3 to 4 of them, and they seem to shower a lot! I know, because I don't get much hot water.
The neighbors are moving out in a month, so I don't have much time to experiment. There is no way to interrupt the electric circuit to insert a meter; so I am thinking, maybe an induction meter would be feasible? How reliable would it be?
EDIT: actually, turns out the dryer plugs into a standard 220V outlet. But heater probably takes much more electricity anyway, right?
