A little understanding
goes a long way.
How is the cost worked out?
Multiply the heater’s power in kilowatts by the hours it runs and your unit rate. A 2 kW heater for 1 hour uses 2 kWh.
Cost = kW × hours × pence per kWh
What about the thermostat?
Once a room is warm, the thermostat switches the heater on and off. In practice many heaters run at full power for only 50–70% of the time.
How accurate is this?
It gives a good estimate for planning and ordering. Check the coverage and sizes on the products you buy, measure carefully, and keep receipts so you can return unopened extras.
