Was thinking the same but using BTU's 50 gallons = 400 lbs of water, if 200 degress when you get home, and cool it to 80 before you quit you have (400 lbs x 120) 48,000 btu's of heat, convert that to KWH 14 kwh at $0.15/kwh = $2.10 worth of electric heat. All assuming you get 100% of the heat stored transferred.

Our numbers don't match up but the answers the same.

1500 watt heaters cost $0.22 per hour to run
