Typical water use?

[Aroastdinnerisnotahumanright]

I'm going through my bills and am wondering what you consider normal hot water usage as this is the first time I've had a central system in a block of flats.

As a single person I apparently consume roughly 80 kilowatts of hot water per month. I googled and couldn't really see if this is normal, what do you think? It would only be for showers and hand washing dishes, I don't know if the washing machine uses it. Thanks for any help!

I have never heard of water being charged in KhW, but okay!

I assume you are not being charged for things you heat yourself, which includes things like washing machines that self heat independently of any communal heating and hot water systems.

So our H and HW run on oil, I literally measure it throughout the year with a dipstick in a large tank and record it in a spreadsheet, so I know exactly how many KwH we use.

In summer we use 1.6L a day to heat a big water tank. 1.6L of oil x 10.36 KhH you get to each litre of oil = 16.57 kWh per day. in winter when the pipes to the boiler in the garage to the house are colder, that usage doubles.

That’s enough water for me to have a roll top bath and the OH to have a shower with a shower head that uses a lot of hot water, and have maybe one bowl of hot water left for washing up. So I would say your usage is on the very low end and not anything that makes me raise an eyebrow.

You may find it goes up a lot in winter simply because pipes are colder so it uses more energy just to get to you.

Thanks for your detailed response! It's is kw because it's just hot water and underfloor heat for the flat but the heat isn't being used now, I have a seperate Thames water bill (endless bills!)

Is this in lieu of a standard bill for heating and hot water that would normally be within the electricity or gas bill?

So your electricity bill (because I'd think you probably don't have gas?) is for cooking, appliances including the washing machine, which are almost always cold fill these days, lighting and things like TV and device charging? So your electricity bill should be quite low?

Is the 80 kW actually 80 kWh? Does it vary throughout the year as you use your heating?

It's hard for people to compare as most people don't use this sort of system, it sounds like a 'heat network'?. But there can be issues for users because it's not subject to the domestic price cap, and is charged at commercial rates, which can be higher.

Moneysaving Expert has an article about it, I don't know if there is anything useful in that?
