another question! Hot water on all day or as and when?

hartleysjam

is it more cost effective to have the hot water heating all day or just as and when you need it?

I was told that if you keep turning it on and off you use more energy?

I have my hot water on for 30 mins in the morning and thats plenty long enough for plenty of hot water during the day.
If i need extra if the family have baths etc i just give it a quick boost in the evening for 30 mins.
No need to have it on all the time its just a waste.

Its like keeping a kettle on all the time so you have instant hot water when you want a drink.

Ahhh not again!

Would you keep your kettle simmering all day because you use more energy by switching it on and off?

There are literally scores of threads on this - timed is cheaper; absolutely no question about it!

That said, the difference is not as much as some people believe - provided you have a well insulated Hot water tank.

I also have my hot water on for 30 minutes in the morning (that's with a 20-odd year old gas boiler and 210 litres tank) and it's enough for me. I obviously do put it on for longer when I've got family or friends staying over for a few days.

Apoligies for the obvious repeated thread :silenced:

Thanks for the replies though

A well worn question and one which is often replied to with hearsay or guesswork. I can only say that I've used both methods and the "always on" method worked out about £50 a year dearer. I would never be churlish enough to offer advice based purely on my own circumstances but I consider the extra £1 a week worth it to have guaranteed hot water whenever I want it.:)

I say this every year and I'll say it again: Can this topic be made into a sticky?

The other way is to rely on the law of physics!

Whilst 'on 24/7' is undoubtedly more expensive, it is also pertinent that any heat lost from the tank warms up the fabric of the house - which is why tanks are usually situated in airing cupboards - so for much of the year the 'lost' heat isn't wasted.

On=meter turning
Off=meter not turning..
