How much does it cost to run a electric heated towel rail?
A typical electric heated towel rail draws about 400 watts. Used 2 hours a day, that works out to roughly $0.14 per day, $4.14 per month, and $49.64 per year on an average electricity rate of 17¢ per kWh. Heated towel rails typically draw 300-500 watts and are often left running for extended periods.

Based on 292 kWh per year. Adjust the price per kWh to match your latest electricity bill for an exact figure.
The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same electric heated towel rail can cost two or three times as much depending on where you live. Enter your exact rate in the calculator above to get a figure tailored to your bill.
As a bathroom device, the electric heated towel rail sits in the middle of most household energy budgets. The number that moves your bill is total run time, so the usage hours in the calculator above matter as much as the wattage.
At 400 watts, the electric heated towel rail is a low-power device, so its cost per hour is small. The annual total only becomes meaningful if it runs for many hours a day — which is exactly why long-running low-wattage devices are easy to overlook on a bill.
Over a full year this electric heated towel rail uses about 292 kWh of electricity and is responsible for roughly 116.8 kg of CO₂ emissions on an average grid. Because it runs more or less year-round, even a small reduction in daily use carries straight through to a lower annual total.
To put the draw in everyday terms, one hour of running this electric heated towel rail uses about as much electricity as charging a smartphone 33 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this electric heated towel rail is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $9.93 every year — money that an efficient replacement can recover over its lifetime.
