No Hot Water

Time to boil the kettle for a wash like we used to do

No idea nina but this should bump it up again!

try switching the boiler off at the plug leave a few minutes then switch back on again...if that doesnt work check your thermostat in case its been turned down by mistake ...then check your timer...

Do you have a trip switch on the immersion heater? This can trip without any warning or if you haven't used hot water for a bit.

If you have the radiators on then the water pressure is fine. It must be something else.

I know little about combi boilers but :-

The radiators are on a different circuit from he hot water, so they may well work without there being hot water from the taps.

Our electric shower does not work if the mains pressure drops significantly.

So low water pressure could well be your problem.

Does your boiler have a pressure gauge ?

Which water company are you with ?, check their web site, they may be doing some work.

Is there an error notice on boiler?

The water in the raiadtors is the same water going round and round, the shower and hot taps use water from the hot tank (which got to the tank via the cold tank and the mains coming into the house)

Do you have water coming from the cold taps? If not, the problem is either outside your house, maybe a burst main somewhere, or inside before the tank. Look into your cold tank, you will see which.

If you have cold water but not hot, the problem is in heating the water (boiler? immersion thermostat? thermostsat kaput?) or in letting it get to the taps and shower (valves?)

If

Elegran, Nina has a combi system, the hot water from the taps comes direct from the mains via the boiler, there is no hot water tank, which is why low mains pressure may be the problem.

googled "No water from hot tap" and found a video on YouTube www.youtube.com/watch?v=uxFEKtJo95w

It could be an airlock in your pipes - there is a video about that too.

Missed that bit of her post, GandT Could be sudden low pressure - if she searches online for notices from whoever supplies her area with water, they may have news about work on supply pipes causing a problem, or possibly damage to a pipe.

We had a new electric shower fitted last year. Mrs P ,tried it and said how good it was, I them tried and it stopped working, the lights indicated that the mains pressure was too low. I was concerned before we fitted it as our pressure is low, came down swearing and thinking that I was going to have to install a pump. Then I found a message on my phone from the water company apologising for a sudden drop in pressure due to a mains failure locally, which should be fixed within an hour or two. Problem solved.

We have just had the same problem and it was an airlock. Hope it gets fixed soon.

Just to clarify the pressure from the taps and the shower does not seem to have changed.
It's just not hot.
Next door have been having a new kitchen fitted. I wondered if their pipes are connected to ours at any point but our flow is the same as usual. I will be on the phone on Monday, just wondered if anyone had ideas. Thanks for replies.
