Boiling water

Helenmaxc

I drink GALLONS of coffee 
In excess of 20-30 cups per day.
I swear I’m caffeine immune, I just enjoy the taste.
I’m curious, is it cheaper to boil just what I need per cup or fill the kettle & decant into a flask; from which I make each cup?
I have a few flasks & could easily reduce the frequency of kettle boiling by ensuring it’s full on every boil.
my ‘one cup’ kettle has died after 5 years of battering so I’m back to a standard kettle, these price hikes are terrifying me but no coffee is a far greater fear! 😬😬😬

thanks in advance 🙏

The energy needed to boil 1 litre of water is around 0.1KWH which would cost less than 3p at the price cap. I don't think you are going to break the bank no matter how you do it.

It will be slightly cheaper to fill the flask, but not by much and not really worth the effort. Just use a small kettle, fill it with a cup full and use that. One improvement you can make is switch off the kettle as soon as you see it's close to boiling rather than waiting for it to notice it's boiling as you don't need boiling water anyway.

( By small kettle, I mean one that is happy with a cup full of water )

I'd be more worried about caffeine intake at 30 cups per day than electricity cost

Maybe make one big batch of coffee and keep it in a big flask or airpot.  A good airpot will keep drinks warm all day

I only boil enough water for a little over 1 cup at a time. Any excess water left in the kettle is used to wash any dishes if I have any left from a meal previous to that cuppa. I never wash the dishes "normally" as a rule unless I used a lot of items as I know I'll have a little boiled water from my next cuppa with usually always covers the small amount of dishes I used on my last meal

To be honest, when I have a lot of dishes I generally half boil the kettle anyway instead of wasting water waiting for the warm water to come through the system lol.

Just like me then lol, but as I have a hot water tank I can't be bothered waiting for the boiler to heat the hot water tank, and then for that hot water to come all the way back down the pipes to just fill up the washing bowl. Far easier to just fill the kettle half full and pour it in, and I wouldn't be surprised if it's cheaper!

As James said caffeine intake should be your first port of call.
Cutting down on the cups of coffee? which will save you money as it's expensive. Thus saving you the boils per day...
Using edale's calculation 20 cups a day us £18 a month saving.
Can't do that? Boil only a bit more than you need.

I thought I drank a lot at 4 cups a day. Surely the OP must be exaggerating somewhat.

I fill the kettle and boil the water to wash up then add a few litres of cold water to cool the hot water a bit. With all my savings it's working out cheaper as I have the boiler temperatures at 49 for hot water and 53 for heating.
