How much does it cost to boil a kettle?

[Hazell B]

Is there a website that gives rough costs at today's prices for electrical use?

I just wondered how much it costs to boil a litre of water in the average kettle, etc.

If there is such a website, I hope it's more accurate that the idiot who worked out (presumably on the back of a fag packet) that a Google search is equivalent to boiling a kettle

You can buy a little plug-in meter which shows your energy usage on any given appliance.

On average a kettle uses the same amount of energy to boil a litre of water as it takes to run a fridge for about seven hours, so it’s a good idea to boil only as much water as you need.

Ah, but that would tell me how much I'm using - when I want to know how much I'm saving. Just to be awkward, like

I bought a stove top 'any surface' kettle the other day, which was £31. It boils on our wood burning stove for free reasonably fast. Looks pretty, too.
We were wondering how many times we have to use it to pay for itself .... and I guess it's about 2000 times.

That's about 18 months, give or take.
It's guaranteed for twenty years, luckily

What? No electricity there?



P.S Incidently my parents have had a big cast iron kettle which they use in winter on their wood burning stove for longer than they've had me.

Yes, my computer's pushbike and hamster wheel powered

My understanding is this. A 3kw kettle running for an hour with 'leccy at say 13p / unit will cost 39p/hr to run. Say the kettle takes 3 mins to boil, then it will cost 3/60 x 39p or about 2p, and 2000 boils would cost £40, so it should take less than that to payback.

Good one Jim

However, I usually only make me a brew as my partner's working some evenings and I didn't mention taking that into account.

did you check out the website i posted?

[Hazell B]

Yes thanks, and Dave's too.
Our electric kettle is fairly new, but I can't remember where it's box is so don't know it's kWh thingy, so just went for averages on the two sites.

You get the added bonus of having a small humidifier when using your kettle on the wood stove. So now you will have investigate the kWh savings otherwise spent on humidification in addition to the savings enjoyed in preparing your tea.

I don't think we need humidifiers here It's almost always raining here so it's almost always humid

[Hazell B]

No humidifier here. Rain, wet dogs breathing everywhere and damp wood being burned

Of course you know you're adding to Global Climate Change using a woodburning stove don't you? I suggest you drag the whole mess down to the beach and use it there. Water boils faster at sea level.

Water actually boils "faster" (at a lower temperature) at a lower pressure. So drag all your stuff up Mt. Everest.

No beaches, no ruddy mountains

Hazell Towers only
