Boiler & tank on/off during holiday???

wildesavings

We're due to go away for a week tomorrow and wondered whether its worth turning the boiler & hot water tank off for the week ?

What's the usual wisdom ? Is it better to leave it on because would it cost more to reheat everything again in a weeks time? Or will we save ourselves a few pennies turning it off? The hot water tank has been playing up lately and I think we'll be replacing it before Christmas as all our neighbours have failed (new build area) so also a little worried it wont work again once we're home.

Some days I think renting might be easier lol

Turn it off!

Leaving it on vs turning it off is cost irrelevant, its not workie no workie, its leak big leaky - turn it off.

how does this tank heat the water, and play up

heating hot water cylinders up for a week costs pounds not pennies.

Turn it off it is, Thank you.

This tank manages to hold vast amounts of beautifully hot water but then not pump it to any of the taps when we want it. You have to turn it off then on again.. . . Repeatedly. This has happened to all the neighbours for about 2-3 months before failing completely by either coming through the ceiling (ARGH) to dying quietly (my preference). So we're heading it off hopefully and have quotes lined up for the week after we return.

turn it off, what is it?

doesn't really explain what type of tank it is, how it's heated/pumped, why it is not coming out of the tap, and why it would come through the ceiling

quotes for what? where is the tank, where and what is the boiler, how old is the system

Would you leave it on for a week, two weeks, a month...?
Your logic about reheating is completely flawed, because if you leave it on, it is constantly losing heat and having to reheat. It takes a fixed amount of energy to heat from x to y.

Most houses have a hot water system that gravity feeds the water from the tank to taps - not by pumping.

Pounds? I hope not.

The OP's house is in a new build area so the Hot Water tank will presumably be well insulated.


Hot Water tanks are tested to a British Standard which measures the heat loss over 24 hours with the water at 65C.


Depending on the size of the cylinder typical losses are between 1.5kWh and 2.5kWh in 24 hours.


So taking a mid point of 2.0kWh a day, that would cost around 8 pence if heated with gas. So 56p a week. I can't think of any scenario where it would cost even £1 a week.

Oh, and you were doing so well Cardew...
