quick question on kWh

Ant555

Please can I ask a question and I apologise in advance if its a daft one!

My current electicity tarriff shows 12.16p per kWh

If I run a 2000W electric heater for 1 hour then has it cost me 24.32p?

Many thanks.

PS I know there is a standing charge but I will be paying that anyway whether the heater is on or off so have excluded it from calculations.

Pretty much. To be a bit more scientific about it though, the heater may not be 'running' for the whole hour. So when it reaches the set temperature it will stop producing heat until it needs to kick in again. So of the 60 minutes - it might only be running for 45 mins and thus may have only used 1500W of leccy.

Kwh = Kilowatt Hour
1000 watts = 1 Kwh.

A 100 Watt light bulb will take 10 hours to use 1Kwh - however, unlike the heater, it will be running constant for that time.

If it has a thermostat.

Yeah ... that's true ... but these days, what with all the modern technology an all ... I'm guessing it will.

If not though, and OP is sweating profusely, then the manual thermostat will kick in ....

Good point on the thermostat and all points noted however the rough value of 25p/hr is good enough for now to do some calculations.
