Ofgem prices
Washing machine 16 – 24 p per use.
Tumble dryer 67p – £1.69 per use.
Dishwasher 21p per use.
Fridge 8 – 22p per day.
Hairdryer 8 – 64p per 8 minutes.
Microwave 8p per use.
TV 2p per hour.
Oven 29p per use.
Kettle 8p per 5 mins.
Air fryer 9 – 16p per use.
Dehumidifier 6 – 9p per hour.
I have in the past, tried to measure power use.
Washing machine, never the same results twice.
Tumble drier, vented was 1 kW and ran for around 90 minutes, heat pump 650 watt for around 2.5 hours, so I would expect 40p in both cases.
Dishwasher so many programs again hard to measure.
Fridge we have an annual use published. Random selection shows 91 kWh/annum so less than 6.2p per day, but looking at a small one, and to be frank I use fridge/freezers it seems odd to select just a fridge.
Hair dryer not used on in years, so not a clue.
TV not measured.
Oven now this is where the figures become interesting, as same food can often be cooked with a microwave, or air fryer, or deep fat fryer, but to measure an oven with three elements, and a 12 way selector switch, and no way to plug into an energy meter, hard to tell what it uses, air fryer is basically a small fan oven, and with both it is really the heat uptime, so used for ½ hour or 1 hour, not a massive change, but the microwave, runs all the time, so reheat coffee, 2.5 mins or cook potato ½ hour the cost will be very different, so microwave or air fryer the selection can cost or save money.
Kettle, well I use a cup boiler for single cup, and if two or more cups, a kettle with element at bottom, so only fill just enough.
Dehumidifier so many different types.
But what I would want to see, is how much to bake a potato in Air fryer, Microwave, or oven. Normally we start in microwave and finish in oven with a Pizza, but if you want to eat, you need to cook, so cooking or not cooking is not really an option, what can save energy is how it is cooked.
Even to wash dishes, in a bowl likely using nearly a gallon of hot water, and much of the energy lost heating pipework, and likely need to do it twice as often as when using a dishwasher. Plus dishwasher can be programmed to use off-peak power.
The washing machine likely uses a lot less water to hand washing, and as with the dish washer, likely the detergent used it not too nice on the skin.
Even tumble dryer, to have to rewash due to bird lime, means often the cost to tumble dry can be off-set.
I am sure no one wants to waste energy, but there is a trade-off. Again tumble dryer, the longer it takes to dry the clothes the less energy it uses, so to compare one which will dry in 55 minutes to one which takes 90 minutes to one which takes 150 minutes is not really any help.
At 12 kWh per day, at 25p/kWh only £3 a day at full rate, with off-peak more like £1 a day, is it really worth the effort?
I would think the largest saving I could make, would be not to use the AC on hot days, but sorry, I no longer like the heat.
Biggest save on energy is likely using programmable TRV heads, so rooms only heated as and when required.
But I will pay £15 a head or more for a meal out, so why worry about £3 for electric. But it seems Ofgem is worried, so what is going on?
