Hi just wondering how much an electric blanket for a single bed costs to run in Dublin Ireland
Hi Stephen,
This will depend on a few factors like what heat seating it is on for and how long it is on per night. Geneally on full setting a single bed electric blaket uses about 70W per hour. Therefore if you used it 2 hours per night 7 days a week it would add in the region of 30 cent per week to your bill.
A electric fan oven at 180 degrees for three hours. How much does this cost

No queries here as I am easily able to calculate it based on the table above. Just wanted to say based on the questions you’ve consistently and repeatedly answered, you have the patience of a Saint!!

Hi why have you not put in a cooker?
For no reason in particular. Ovens can greatly use between 2000w to 5000W per hour in use. 3000W would be a good general rule of thumb so about 60 cent per hour used.

Hi,
I am worried about the annual cost of running a B- rated condenser tumble dryer. The annual KWH is 561.
By my reckoning it’s an additional €35.00 a month but not entirely confident in my calculations.

More like 10 euro a month really.
561 divided by 12 (months) = 46.75kw per month

Would the fan heater and the oil heater not be different prices per hour, even though they’re both 2500w. The fan heater element would be constantly on to heat the air. While the oil heater element turns off and on over the period of the hour?
