Hi just wondering what would the best settings be for this. Sadly had a surge and clock died. So everything default. Wanting to save on gas.

I did think about hot water on for an hour at 0600 - 0700 and again at 1700-1800 so just twice a day. Wifey is up in morning and little one has a bath in evening. I shower at work so nice saving there.

Any other advice?




 
I only put ours on twice a week. Mainly to keep the legionella away.

We just don't use it. Apart from rare time I want a bath. Just put it on via the app if I want a bath.

Electric showers?
 
The rating on your cylinder says heat loss is 2.08kWh per day, so you'd need to use 2.08kWh of gas to maintain temperature if you set it to be hot all day, that would cost around 15 pence per day at the new price cap (or about £4.60 per month) so not much difference you could make by setting it to come on only at the times you need it. If you don't ever turn it on, the most you could save is £4.60 per month.
Is that right? Not 100% sure of my logic there.

A friend of mine lives in a 3 story town house and it takes so long for hot water to get delivered to their kitchen/bathroom I don't think I've ever hung around long enough to wash my hands in warm water.

It stays tepid most of the time. But usually I just use cold anyway. It only gets cold the day before it's due to come on.

What's funny is the cold water must pass by the central heating as the cold tap is initially hot. Hotter than the hot for 5-10 seconds!

Yes - it's soap that removes germs from your hands, not water temperature (unless it's actually near boiling point, and would therefore scald you)

The CDC seem to think cold water is fine:
Is it better to use warm water or cold water?

Use your preferred water temperature – cold or warm – to wash your hands. Warm and cold water remove the same number of germs from your hands. The water helps create soap lather that removes germs from your skin when you wash your hands. Water itself does not usually kill germs; to kill germs, water would need to be hot enough to scald your hands.

It was more of a comfort thing than a cleanliness.

But it does beg the question of why public bathrooms etc bother to install hot taps if cold water and soap is sufficient. Installation would be a fair bit cheaper too.
 
Cold water might be fine if your hands are "clean" already. Like after using the toilet or before you're going to cook or something and you just want to remove any germs but it's not as good at cleaning if your hands are actually dirty. Any type of oil or grease or even just ground from gardening doesn't clean off as easily with cold water.

because in winter no one wants to wash their hands with freezing cold water and I'm assuming the people who own the washrooms would rather people be hygienic.
It's probably a legal requirement anyway

erm oils water proof and so is grease... that's why people buy soap
 
Minor point but whoever installed that tank did it wrong. You can't have a shut off on the hot water feed like that is my understanding!

We run ours each day in the evening and it's hot in morning no issues for 2 long showers (180l cylinder).

You do raise a good point. 7.488p is our gas with a 37.28p standing charge.

We don’t use the electric to heat it only the gas.
