The energy value of gas used in a home is measured in KWH. The home owner has a prepayment meter and pays £30 into his account. With a prepayment meter, gas cost 15p per KWH. Use the below equation to calculate the total number of hours that the gas boiler would operate for £30.
Energy Transferred = power x time
Total costs = number of kilowatt hours x cost per kilowat-hour
Energy Transferred = power x time
Total costs = number of kilowatt hours x cost per kilowat-hour

=30/0.15=200 KWH
Number of hours for boiler
= 200 KWH / power of boiler
The number of hours will not be know until the power of the boiler is known.
