A relatively simple equation can be used to work out electric heated towel rail running costs, with the same formula able to be used for practically any electrical appliance.
The equation to use is as follows…
Watts / 1000 = Kw X Hours in Operation = kW x kWh rate = Cost
An electric towel rail’s wattage will typically be displayed on the device, and is noted in the product descriptions on BestHeating.com.
As of April 2023, the kWh rate can be worked out off a standard UK electricity tariff value of 33.2p/ kWh according to the UK government’s Energy Price Guarantee.
