Question: how much does it cost to run heat tape?
Answer: If the tape is 6 feet long, it will use 30 watts when heating the pipe. To run this tape for one day, a homeowner would use 0.72 kilowatt-hours (kWh), which would cost 14 cents at $0.20/kWh (approximately the current rate in Fairbanks), or approximately $20 for four months.
