How much does it cost to run a heated towel rail?
A typical heated towel rail draws about 350 watts. Used 4 hours a day, that works out to roughly $0.24 per day, $5.95 per month, and $71.40 per year on an average electricity rate of 17¢ per kWh. Heated towel rails consume 300-400 watts continuously when in use and typically run several hours daily.

Based on 420 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 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 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 350 watts, the 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 heated towel rail uses about 420 kWh of electricity and is responsible for roughly 168 kg of CO₂ emissions on an average grid. Since it is used only part of the year, your real footprint scales with the season — the annual figure assumes a typical usage pattern.
To put the draw in everyday terms, one hour of running this heated towel rail uses about as much electricity as charging a smartphone 29 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this heated towel rail is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $14.28 every year — money that an efficient replacement can recover over its lifetime.
