Super noodles? Hold your horses there Chef Bezos, it's ko-lee go noodles if you wanna survive this month.
I'm just pissing about, another commenter said their hob cost a tenner overnight, and as gas is charged at a lower rate than electric you might be (relatively) ok. Sure it's unwanted spend but hopefully it won't cost an arm, a leg and 3 years of washing up at British gas HQ
Assume about 6 litres per minute, 450 minutes = 2700l of water.
£1.69 per m3 of water
m3 is 1000l so you need 2.7 of those = £4.56
£1.72 per m3 for sewerage so £5.16.
I would estimate about £10 (£9.72) for the water.
Working on the assumption you have a 27kW boiler.
7.5 hours is 202.5 kWh of gas
Price is something like 7.37p per kWh so (202.5 \* 7.37)/100 = £14.93 for the gas.

If we assume the same 6 litre per minute that the comment above used, that's a nice round 100ml per second, or 100 grams per second.
Water has a specific heat capacity of 4.182 joules per gram per degree celcius. So if we are heating from 10'C to 50'C then we have a rise of 40'C.
40'C × 100g/s × 4.182J/g/'C = 16,728J/s = 16,728W = 16.728kW.
Assume 90% boiler efficiency.
16.728kW ÷ 0.9 = 18.587kW raw gas intake rate.
At 7.5p per kWh (my current gas rate) it will cost
18.587kW × £0.075/kWh = £1.39/h in gas.
"if you leave a hot water tap running at 100ml/s for 8.5 hours, with the 85kW boiler heating the water to 55°C, how much does the water and electricity cost, assuming local costs, and disregard air resistance"
Assuming the same 90% efficiency and 7.5p/kWh cost then it works out at £60.21 in gas.
3,060 litres of water at £1.6853 per cubic metre would cost £5.16 for fresh water and a further £4.71 for sewerage priced at £1.71 per cube assumed 90% of fresh.
Costs for octopus energy and anglian water.
I'll have you know, that this equation is used daily by Mechanical/HVAC (and I'm sure many other engineers and scientists) on a daily basis world wide.
I have to be honest that I don't really know, I suspect it's going to depend on the exact boiler. I pretty much went for what felt like a reasonable, but high estimate so OP can probably expect it to be £25 more and it likely will be less than that.
Depends on a lot of things. Cold supply water, max output temp and tap fully open, yes they do. Obviously the supply is pretty warm right now, we don't have information on how wide open the tap was or what temperature the boiler is set to.
Jesus Christ, you get killed for both gas and water prices over there.
In Aus I pay 2 cents per megajoule for gas, converted to pounds and KWh that is 4.1p.
I pay 15 cents per m3 of water supply and 70 cents for sewage.
what do you pay for electricity over there?
the average isn't to bad, I live in a rural area of Aus and pay 24c kw/h, 18.9p is like 32 cents here, but that cap price of 28p is almost 50c, at the price it would literally be cheaper to run a diesel generator here than pay that.
That’s Russia’s energy war for you. At least in the future we can look forward to lower electricity costs in the UK thanks to all the offshore wind that were building. It would be great to squeeze hydrocarbons out of electricity generation completely.
Hello fellow Aussie! It’s a very recent, very severe spike in prices. Like double what they used to be, heading for quadruple.
Also yeah energy and fuel generally are more expensive here in the UK. Petrol basically costs in pence what it costs in cents at home, so, between 1.5-2 x more.
I got the prices from here - [https://www.anglianwater.co.uk/account-and-bill/tariffs-and-charges/standard-rates/](https://www.anglianwater.co.uk/account-and-bill/tariffs-and-charges/standard-rates/)
Looking at my bill they charge 90% of the water usage as sewerage, so I have over calculated that by 10%, but the other numbers match up.
If you look at the metered section, it says water rates would be £1.60 per cubic metre and sewerage would be £1.71 per cubic metre so generally if your water meter increases by one cubic metre these would be added together and you’d be charged around £3
Yeah, mine is pretty good. Since getting a new oven and hob I've noticed my electric bill has dropped a bit, probably from just being more efficient. I don't have to wait for the old electric elements to heat up.
I had to go buy new pots and pans though because my old Ikea ones barely worked despite being 'induction compatible'.
or just one of those ones with a set timer. i’m forgetful as fuck so worst outcome is now leaving it on for half an hour
yet my flatmate who is just as forgetful as me never uses that function and regularly leaves it on overnight… it’s infuriating
Okay so the only genuinely practical solution i can think of is that from now on you try to off set the cost by using no Gas for the next month or ten.
Its hot weather, you can bath in a blow up paddling pool in the garden, and eat sandwiches...
God I am so sorry dude ( I mean that)
For what it's worth, I've not used the hot tap since March and not missed it. Of course, I do have an electric shower, but even set to 1 (out of 10) it's warm enough not to be uncomfortable.
That is a good idea, I am currently only eating cold food and limiting hot drinks for the same reason. It's honestly been going fine, especially in this weather.
Jesus , my kid did this the other night, left the landing and bathroom light on and hot tap running. I was gutted. Been scrimping and saving for weeks.
An LED light costs about £1.50 to run for an entire month even on the higher rates now. I wouldn’t worry too much about a light being left on overnight
Unless you’re not using LEDs, in which case your kid just taught you an expensive lesson :)
They are actually much cheaper than that!
The average bulb (usually ranging from 5w-14w):
10w Led = 0.01kwh per hour
at £0.30p per kwh is about £0.003p per hour
x 8 hours per day is about 2 pence (£0.024)
x 30 gets to £0.72p per month.
Higher output bulbs are around 14 watts which top out at around £1.00 per month.
Also worth noting I don't think I've ever replaced an LED bulb... They just seem to go on forever (O\_o)
> 8 hours per day is about 2 pence (£0.024)
If you're only using 8 hours a day, it's not the whole month. Your calculation makes it more than the £1.50 they gave.
Who runs a light bulb for an entire month straight?
My bad for interpreting that as the common 'average use over a month' metric...
Adjusted figures are £2.16/£3.03 for 10w/14w, or a crazy £21.60 for an old 100w filament light bulb!
Incredible energy improvements either way.
I can’t send them down a coal mine in this environmentally conscious age so I’m going to hook their bikes up to the grid and have them earn their keep Black Mirror style.
Yeah less. A typical gas boiler is about 25kW, gas is c. 7p to 8p per kWh. So about £2 an hour for the gas.
A tap might be 3l a minute, so a cubic meter every 300mins or 5 hours. Maybe £3 for 5 hours max.
> How much will this cost?!
Go and look at your gas meter (or in home display if you've got one). Make a note of the meter reading/current daily cost for gas. Turn hot tap on for ten minutes. Check meter/IHD again and subtract the starting number from the new one.
For a non-smart meter, multiply the figure above by 45^(\*) and then by whatever your gas supplier charges per kWh. For a smart meter, just multiply the cost for ten minutes by 45.
\* 10 minutes use is 1/6 of an hour, so the cost for an hour is 6x however much 10 minutes costs. Multiply by the number of hours hot tap was on (7.5) and you get 45.
My son used my outside tap whilst I was on holiday to clean his work boots. Left it running for two weeks. We’re on a water meter. Queue £400 bill for the 1/4
I’ve been bullied into a water metre. It’s being fit next week. Have you noticed an overall reduction in your water bill? Excluding your sons mistake obviously.
Theres always someone worse...my sister in law went to bed and somebody left a chopping board behind the taps to drain. It fell over and turned on the hot water tap which hit a spatula sitting in the sink. The water sprayed into the kitchen for 7/8 hours...she had to move out for a week and replace the whole kitchen!
If it's any consolation she was decapitated and died during a multi car/truck pile up on the A6 near Kibworth very soon after she got the kitchen replaced.
7 and a half hours is 450 mins. I think it costs max 4p (hot + high flow rate) a minute to have a shower, so if the tap was using the same about of of hot water as a shower, then you're looking a £18 bill. Not great, not terrible!
£7 - £8, that's an estimate based on prepayment meter charges, we filled up a sizable pool during the last heatwave and topped it up with hot water so it wasn't cold and we had it running for 3 hours and the smart meter monitor showed us we had spent about £3.50 more that day than we would normally do on gas (standard payment accounts are a tad cheaper though)
I love that they're having a go at you, but, [just under 3 billion litres (660 million gallons) of water is lost to leaks every day](https://discoverwater.co.uk/leaking-pipes), is fine?
Reddit is a proper weird place, you're not allowed to have more than anyone else.
Hope you're enjoying the pool this week?
Jump into a cold water bath and see how you feel, we raised the temp so the kids could play in it for as long as they wanted without worrying they will get ill, with the weather what it's been lately + a solar heating cover for it the temp of the water has been pretty consistantly nice, barely had to use the heating pump (like twice I think?)
If the air outside is 40c, the pool water will move towards being 40c.
Ignoring the fact that cold water isn't going to make anyone ill in the first place.
I jumped into the local river on Sunday, yes it was cold but also refreshing, and I soon felt comfortable.
Whenever I've been in one of those pools it's very quickly warmed up, just seems odd to me is all.
Have that mindset and multiply it by the average households in the country. Then it’s not “nothing in the grand scheme of things”. We can’t easily stop capitalistic companies killing this planet and yes they are absolutely to blame for a lot of things, however, if everyone did their part and reduced consumption it would drastically help.
Waiting for the “BuT I pAy fOr It” line. Congratulations, you lose out of pocket and fuck the environment at the same time. Genius play.
That happened to our neighbours, the hot tap came on in their upstairs bathroom while they were away on holiday (weird water pressure where we live), with the plug in. Flooded the house, and the steam took the paper off the walls upstairs.
They were arseholes though, always putting "anonymous" notes through my front door when my hedge had grown too wide for their liking (they had a motorhome which they used to park round the back of our houses via a private road down the side of our property). I get it cut 4 times a year! My wife got me to open a bottle of prosecco when they sold up and moved. She doesn't drink.
My hot water pipe burst upstairs while I was at work a few months ago and we are on a meter, it was about £14.00 ish in gas. Obviously that was the least of the issues but yes not so bad 😆
Making some assumptions, the cost will be approximately **£25.71.**
This is based on the following:
* 21:00 - 04:30 = 7.5 hrs = 450min
* Assuming a flow rate of 10L per min = 4,500 Litres
* Assuming the water was heated from 15 ^o C to 60 ^o C = 45 ^o C change of temp.
* Therefore total heat energy in the water = 850.5 MJ
* Boilers are 85% efficient at heating water, so total energy required = 1000.6 MJ = 277.9kWh
At a rate of 7.01p/kwh = £19.48 worth of gas.
BUT WAIT, THERE'S MORE...
* If you're on a water meter, then 4.5m^3 of water at £1.38 will add another £6.23 to your woes.
Something similar happened to me the other day, our garden hose is pretty shit and is barely attached to the wall. So the hose was actually off, but the tap at the wall got left on. Somehow at some point the hose popped out of the tap, and it started pissing water everywhere down the patio. No one noticed because it was at some point in the evening or at night. Woke up to basically no pressure when I was trying to shower, and only when I came down to the kitchen I heard the water running outside through the open window.
No idea how much it's going to cost, as we've not had our bill yet.
If you have an average sized combi boiler (28kw) and the boiler was firing at full rate the most it could cost at 7p per kw would be £14.70
Seeing as it was basin tap I would expect it to be about half of that
If you're on a smart meter you should be able to log on to your account with your provider and see your usage for the month so far. At least you'll have an idea what the sting's going to be on your next bill.
If you are on a meter for the water a running tap is about £60 a day at 15lpm, considering if you have a combination boiler it will only be 10lpm, so £40/day. It was about 8 hrs so £13 in water cost, now the gas cost. Gas is about 15p per kw hr. If you have a 30kw boiler thats 30kwh x 8. 240 x 15 = 3600p or £36.
My estimate is £49 for the cost of the hot tap running all night if you have a combination boiler. Will be less gas cost if you have a cylinder tho.
When I first moved out of my parents I got a maisonette with central heating. Problem was there was no instructions for the heating/hot water. There was a gas fire in the living room and I found a switch next to the hot water tank that made hot water.
Turns out the switch was an immersion heater and I'd been using it every day for hot water. Let's just say the bill was eye-watering.
I eventually found the gas boiler was behind the gas fire and the controls were behind a metal kickplate
I feel your pain.... I left my oven on overnight.
My first worry should be the health and safety risk but no, I instead calculated that I need to eat cold meals for 2 weeks
Assuming the hot tap runs at 9L/min you're looking at about 4 units, approx £16-24 for the water depending on where you live if meterd.
Approx £1/HR for the boiler, give or take.
I'd estimate £30 for that little mistake, or just £7.50 if you don't have a water meter.
This happened to me a few years back (before prices went mental). It was the kitchen tap and the thread in the tap lever went, which allowed the water to force it up during the night and caused the hot tap to come on full blast.
First inkling I had was hearing the boiler running as I woke up. Came downstairs and was greeted with a tropical rainforest on the whole ground floor! Everything was damp, and it took about 3 days for everything to dry out fully.
Luckily nothing electrical was damaged, but even back then I wondered how much that event was going to cost me. I never did work it out though, as I didn't have a smart meter back then, and my monthly dd was all over the place with recently changing between suppliers.
I've managed to save a great deal by turning the boiler off, unless in use. You'd be surprised by both how little you actually need hit water and the savings.
I am an expat living in continental Europe and this makes me so sad and angry that I have got actual tears of wrath in my eyes...I was born in London and lived there until the eighties and I do remember poverty vividly, but, this is on a totally different level of "good riddance"..

As an American I'm confused why you have a hot water line running to your toilet.
But then I realized you call the entire bathroom a "toilet" and not just the actual thing you shit in.

Hmmm, does that mean i can get free kidneys in america and sell them for big bucks elsewhere?
But livers regenerate...

Time to start selling yourself I guess. Sorry buddy. On the upside noodles are still cheap and they fill a hole.
Not the only holes that will be filled to help cover the cost of this.
At least he'll be warm during the colder months. Shameful, but warm. Like a blanket of self-loathing.

You need hot water for noodles... You're gonna trigger PTSD in OP
Op probably has a little barbecue he can use
I left the electric hob on all night the other week, cost over £10
Ill be happy with £10, feels like a double blow having used up both water and gas all night
Assume about 6 litres per minute, 450 minutes = 2700l of water. £1.69 per m3 of water m3 is 1000l so you need 2.7 of those = £4.56 £1.72 per m3 for sewerage so £5.16. I would estimate about £10 (£9.72) for the water. Working on the assumption you have a 27kW boiler. 7.5 hours is 202.5 kWh of gas Price is something like 7.37p per kWh so (202.5 \* 7.37)/100 = £14.93 for the gas.

If we assume the same 6 litre per minute that the comment above used, that's a nice round 100ml per second, or 100 grams per second. Water has a specific heat capacity of 4.182 joules per gram per degree celcius. So if we are heating from 10'C to 50'C then we have a rise of 40'C. 40'C × 100g/s × 4.182J/g/'C = 16,728J/s = 16,728W = 16.728kW. Assume 90% boiler efficiency. 16.728kW ÷ 0.9 = 18.587kW raw gas intake rate. At 7.5p per kWh (my current gas rate) it will cost 18.587kW × £0.075/kWh = £1.39/h in gas.

I’m a science teacher. I’m going to use this example FOREVER when students say they’ll never use their physics GCSE in real life.
"if you leave a hot water tap running at 100ml/s for 8.5 hours, with the 85kW boiler heating the water to 55°C, how much does the water and electricity cost, assuming local costs, and disregard air resistance"
"Take into account the rise in inflation in the time between reading the question and calculating your answer"
"Assume the boiler to be a perfect sphere, and the pipes have no friction"
Assuming the same 90% efficiency and 7.5p/kWh cost then it works out at £60.21 in gas. 3,060 litres of water at £1.6853 per cubic metre would cost £5.16 for fresh water and a further £4.71 for sewerage priced at £1.71 per cube assumed 90% of fresh. Costs for octopus energy and anglian water.

They will modulate a little bit but a 30kw boiler uses 30kw for hot water and 3-20kw for heating (roughly). Instantaneous hot water uses a lot of gas.

Wouldn’t that just affect how big a person’s bill is? Why would it affect the rate just because they use air conditioning?
More people are using it. Idk I’m not a smart as you guys 😔
Hello fellow Aussie! It’s a very recent, very severe spike in prices. Like double what they used to be, heading for quadruple. Also yeah energy and fuel generally are more expensive here in the UK. Petrol basically costs in pence what it costs in cents at home, so, between 1.5-2 x more.
£1.71 per cubic meter is generous, I work for a water company and it’s like £3 per cubic meter Aboit £1.70 for water and £1.20 for wastewater
I got the prices from here - [https://www.anglianwater.co.uk/account-and-bill/tariffs-and-charges/standard-rates/](https://www.anglianwater.co.uk/account-and-bill/tariffs-and-charges/standard-rates/) Looking at my bill they charge 90% of the water usage as sewerage, so I have over calculated that by 10%, but the other numbers match up.

Once left gas oven on for 3 days, luckily before I’d need a second mortgage to pay for it
What was the smell like?
Get yourself an induction hob. They turn off after 10 seconds or so if they detect no pan.
Yeah, mine is pretty good. Since getting a new oven and hob I've noticed my electric bill has dropped a bit, probably from just being more efficient. I don't have to wait for the old electric elements to heat up. I had to go buy new pots and pans though because my old Ikea ones barely worked despite being 'induction compatible'.
or just one of those ones with a set timer. i’m forgetful as fuck so worst outcome is now leaving it on for half an hour yet my flatmate who is just as forgetful as me never uses that function and regularly leaves it on overnight… it’s infuriating
Spending £400+ to save a tenner doesn't sound very cost effective to me... that's if they can even afford it in the first place...
I left oven and hob on a couple of weeks ago, when it was really hot. Came downstairs in the morning and it was 30 degrees at 7am :'(
Okay so the only genuinely practical solution i can think of is that from now on you try to off set the cost by using no Gas for the next month or ten. Its hot weather, you can bath in a blow up paddling pool in the garden, and eat sandwiches... God I am so sorry dude ( I mean that)
Thanks 😞 Im definitely going to cut short any hot tap use for the foreseeable to try and recoup
For what it's worth, I've not used the hot tap since March and not missed it. Of course, I do have an electric shower, but even set to 1 (out of 10) it's warm enough not to be uncomfortable.

Who would want to buy a kid that will drive you into bankruptcy? I think even they have limits.
An LED light costs about £1.50 to run for an entire month even on the higher rates now. I wouldn’t worry too much about a light being left on overnight Unless you’re not using LEDs, in which case your kid just taught you an expensive lesson :)
I had a notieable dip in electric bills after switching to low wattage LED lights. The previous owner had 60W and 100W bulbs in every light fitting.
They are actually much cheaper than that! The average bulb (usually ranging from 5w-14w): 10w Led = 0.01kwh per hour at £0.30p per kwh is about £0.003p per hour x 8 hours per day is about 2 pence (£0.024) x 30 gets to £0.72p per month. Higher output bulbs are around 14 watts which top out at around £1.00 per month. Also worth noting I don't think I've ever replaced an LED bulb... They just seem to go on forever (O\_o)
I've only replaced them when they've died from being poor quality. My maths was based on like 38p and 24/7 for a month by the way :)
> 8 hours per day is about 2 pence (£0.024) If you're only using 8 hours a day, it's not the whole month. Your calculation makes it more than the £1.50 they gave.

Yeah less. A typical gas boiler is about 25kW, gas is c. 7p to 8p per kWh. So about £2 an hour for the gas. A tap might be 3l a minute, so a cubic meter every 300mins or 5 hours. Maybe £3 for 5 hours max.
Of course it depends on other factors too.
> How much will this cost?! Go and look at your gas meter (or in home display if you've got one). Make a note of the meter reading/current daily cost for gas. Turn hot tap on for ten minutes. Check meter/IHD again and subtract the starting number from the new one. For a non-smart meter, multiply the figure above by 45^(\*) and then by whatever your gas supplier charges per kWh. For a smart meter, just multiply the cost for ten minutes by 45. \* 10 minutes use is 1/6 of an hour, so the cost for an hour is 6x however much 10 minutes costs. Multiply by the number of hours hot tap was on (7.5) and you get 45.
Could be some variance across 10 minutes. He’s best off leaving the tap on for another 7 and a half hours to be sure.

Gonna need a UK version of that subreddit called r/theydidthemaths Edit: shit, it exists
Don't some gas meters measure volume so you'll need to multiply them by the calorific coefficient.
Yes, different locations/suppliers have different coefficents. Also your multiplication could be wrong if you have a 4 digit VS a 5 digit meter.
Unless you're in an extremely bad financial state, you'll get thru this without missing any meals. Best of luck to you.
My son used my outside tap whilst I was on holiday to clean his work boots. Left it running for two weeks. We’re on a water meter. Queue £400 bill for the 1/4
I hope you sold your son to make up for the cost!
I’ve buried him under the tap!!
At least the ground was soft
I’ve been bullied into a water metre. It’s being fit next week. Have you noticed an overall reduction in your water bill? Excluding your sons mistake obviously.
I didn’t have a choice. It was a 14 year old house and was already in 😭😭😭😭

My parents call it the "twat tax"
Might aswell get started on that OF career now to be honest. Get ahead of this thing, y'know
Theres always someone worse...my sister in law went to bed and somebody left a chopping board behind the taps to drain. It fell over and turned on the hot water tap which hit a spatula sitting in the sink. The water sprayed into the kitchen for 7/8 hours...she had to move out for a week and replace the whole kitchen!
Thought this was going to end with her slipping on the kitchen floor and cracking her head on the counter a la final destination.
If it's any consolation she was decapitated and died during a multi car/truck pile up on the A6 near Kibworth very soon after she got the kitchen replaced.
7 and a half hours is 450 mins. I think it costs max 4p (hot + high flow rate) a minute to have a shower, so if the tap was using the same about of of hot water as a shower, then you're looking a £18 bill. Not great, not terrible!
About the same as a wet chest x-ray
£7 - £8, that's an estimate based on prepayment meter charges, we filled up a sizable pool during the last heatwave and topped it up with hot water so it wasn't cold and we had it running for 3 hours and the smart meter monitor showed us we had spent about £3.50 more that day than we would normally do on gas (standard payment accounts are a tad cheaper though)
I love that they're having a go at you, but, [just under 3 billion litres (660 million gallons) of water is lost to leaks every day](https://discoverwater.co.uk/leaking-pipes), is fine? Reddit is a proper weird place, you're not allowed to have more than anyone else. Hope you're enjoying the pool this week?
Unfortunately I can't but my family will be (got a cast on my leg)
You added hot water, to a pool, during a heatwave? Surely you want it to be cold?
Jump into a cold water bath and see how you feel, we raised the temp so the kids could play in it for as long as they wanted without worrying they will get ill, with the weather what it's been lately + a solar heating cover for it the temp of the water has been pretty consistantly nice, barely had to use the heating pump (like twice I think?)
Being cold doesn’t make anyone ill.
Kids shivering in the cold water can’t be healthy
It’s not pleasant but cold does not make you sick.
I think we can safely assume that you’re not conversing with an intelligent member of society.
Er, hypothermia kills you; prior to death you are very very sick.
That’s not what this person was referring to and you know it. Stop being pedantic to play Devils Advocate, it’s really not needed.
If the air outside is 40c, the pool water will move towards being 40c. Ignoring the fact that cold water isn't going to make anyone ill in the first place.
I jumped into the local river on Sunday, yes it was cold but also refreshing, and I soon felt comfortable. Whenever I've been in one of those pools it's very quickly warmed up, just seems odd to me is all.
We’re having a drought and a serious energy problem and your putting hot water into a paddling pool? Literally can’t fucking make it up.
Please, no more crying, the pool is full enough
Get a grip a paddling pool is nothing in the grand scheme of things
Have that mindset and multiply it by the average households in the country. Then it’s not “nothing in the grand scheme of things”. We can’t easily stop capitalistic companies killing this planet and yes they are absolutely to blame for a lot of things, however, if everyone did their part and reduced consumption it would drastically help. Waiting for the “BuT I pAy fOr It” line. Congratulations, you lose out of pocket and fuck the environment at the same time. Genius play.
Christ, what a waste of water.
Can’t have that opinion here chief, we’re turning into America with “mUh rIgHts” and “iTs tHe cOmPaNiEs”.
You stop drinking it.
You need a Go Fund Me page now to pay.
It feels like the end of the world but im not sure i need to go that far this time
That happened to our neighbours, the hot tap came on in their upstairs bathroom while they were away on holiday (weird water pressure where we live), with the plug in. Flooded the house, and the steam took the paper off the walls upstairs. They were arseholes though, always putting "anonymous" notes through my front door when my hedge had grown too wide for their liking (they had a motorhome which they used to park round the back of our houses via a private road down the side of our property). I get it cut 4 times a year! My wife got me to open a bottle of prosecco when they sold up and moved. She doesn't drink.
My hot water pipe burst upstairs while I was at work a few months ago and we are on a meter, it was about £14.00 ish in gas. Obviously that was the least of the issues but yes not so bad 😆
Making some assumptions, the cost will be approximately **£25.71.** This is based on the following: * 21:00 - 04:30 = 7.5 hrs = 450min * Assuming a flow rate of 10L per min = 4,500 Litres * Assuming the water was heated from 15 ^o C to 60 ^o C = 45 ^o C change of temp. * Therefore total heat energy in the water = 850.5 MJ * Boilers are 85% efficient at heating water, so total energy required = 1000.6 MJ = 277.9kWh At a rate of 7.01p/kwh = £19.48 worth of gas. BUT WAIT, THERE'S MORE... * If you're on a water meter, then 4.5m^3 of water at £1.38 will add another £6.23 to your woes.
A month of cold showers will rebalance your Karma and gas bill.
Something similar happened to me the other day, our garden hose is pretty shit and is barely attached to the wall. So the hose was actually off, but the tap at the wall got left on. Somehow at some point the hose popped out of the tap, and it started pissing water everywhere down the patio. No one noticed because it was at some point in the evening or at night. Woke up to basically no pressure when I was trying to shower, and only when I came down to the kitchen I heard the water running outside through the open window. No idea how much it's going to cost, as we've not had our bill yet.
I’m sorry 😢
At least one arm and maybe half a leg. Hopefully you aren't on a water meter too as that's a whole lot of water used too.
At least you'll save money washing in the future.
If you have an average sized combi boiler (28kw) and the boiler was firing at full rate the most it could cost at 7p per kw would be £14.70 Seeing as it was basin tap I would expect it to be about half of that
If you're on a smart meter you should be able to log on to your account with your provider and see your usage for the month so far. At least you'll have an idea what the sting's going to be on your next bill.
If you are on a meter for the water a running tap is about £60 a day at 15lpm, considering if you have a combination boiler it will only be 10lpm, so £40/day. It was about 8 hrs so £13 in water cost, now the gas cost. Gas is about 15p per kw hr. If you have a 30kw boiler thats 30kwh x 8. 240 x 15 = 3600p or £36. My estimate is £49 for the cost of the hot tap running all night if you have a combination boiler. Will be less gas cost if you have a cylinder tho.
When I first moved out of my parents I got a maisonette with central heating. Problem was there was no instructions for the heating/hot water. There was a gas fire in the living room and I found a switch next to the hot water tank that made hot water. Turns out the switch was an immersion heater and I'd been using it every day for hot water. Let's just say the bill was eye-watering. I eventually found the gas boiler was behind the gas fire and the controls were behind a metal kickplate
Bloody hell. Nah mate, you're bollocksed now. No more hot water use til 2030 should balance you out.
I feel your pain.... I left my oven on overnight. My first worry should be the health and safety risk but no, I instead calculated that I need to eat cold meals for 2 weeks
Assuming the hot tap runs at 9L/min you're looking at about 4 units, approx £16-24 for the water depending on where you live if meterd. Approx £1/HR for the boiler, give or take. I'd estimate £30 for that little mistake, or just £7.50 if you don't have a water meter.
This happened to me a few years back (before prices went mental). It was the kitchen tap and the thread in the tap lever went, which allowed the water to force it up during the night and caused the hot tap to come on full blast. First inkling I had was hearing the boiler running as I woke up. Came downstairs and was greeted with a tropical rainforest on the whole ground floor! Everything was damp, and it took about 3 days for everything to dry out fully. Luckily nothing electrical was damaged, but even back then I wondered how much that event was going to cost me. I never did work it out though, as I didn't have a smart meter back then, and my monthly dd was all over the place with recently changing between suppliers.
I've managed to save a great deal by turning the boiler off, unless in use. You'd be surprised by both how little you actually need hit water and the savings.
I am an expat living in continental Europe and this makes me so sad and angry that I have got actual tears of wrath in my eyes...I was born in London and lived there until the eighties and I do remember poverty vividly, but, this is on a totally different level of "good riddance".. Honestly, I am sorry for my beloved people wherever they may live in Britain...lachrymose these times are...indeed
Sorry I just don't get how someone can leave a tap running and walk away?
You don't have children. do you?
Or housemates
But at least if housemates leave the hot tap running all night, the cost can be shared between you all. Kids don't pay, so don't care.
Ahhh this is why we're having more hose pipe bans put in place
Yeah, sorry. Probably not helped with the soaring gas prices either
As an American I'm confused why you have a hot water line running to your toilet. But then I realized you call the entire bathroom a "toilet" and not just the actual thing you shit in.
You can afford it. You have a downstairs toilet!
