Plumbing question

[Pubey]

Hi all,

Just moved into our new house last week. There is a combi boiler (Greenstar 24i) with a digital panel on the front and a RF thermostat downstairs.

When we moved in hot water came out of the taps and shower so we were happy. This morning got up early for first day back at work to find that there was no hot water coming from the shower (but there was from the taps), so had a quick bath instead. On the digital display on the boiler there appear to be settings for hot water timings, and this is currently running the OFF programme. This confuses me, because firstly I didn't think a combi boiler would need a timer, it is just on demand, and secondly because it's been working fine for the previous week.

Any help would be greatly received, before I call out a plumber for something very silly and embarrassing!

I have a Worcester Bosch Greenstar 30 CDI with an RF thermostat.

My shower and taps work fine with the HW timer set to off. I believe this timer is for the keep hot facility - there is a small tank inside the boiler to provide instant hot water (presumably for those who can't wait 20 seconds for the boiler to kick in)

I would suspect the shower. BTW if it is an electric it is not fed from the boiler.

Ahh that sounds sensible. I'm 99% sure it's an electric shower, so will investigate! Cheers Rudi

Rudi, perhaps you can help me as well then? I live in a block of purpose built flats. My problem is that whenever i flush the toilet there is a horrible loud continuous groaning sound from the pipes that lasts about 2 minutes while the cistern is filling up behind the bog. Now i also have a water tank in my airing cupboard with a ballcock but this dosnt fill for whatever reason. I'm not 100% sure whether its meant to or not. When i flush the toilet, and then go to wash my hands the noise gets louder until i turn the tap off. I also think the bloke in the flat upstaris has the same issue. Are they connected?
Cheers Steven

I'm not a plumber I'm afraid but I know some pipes can vibrate when water flows though them - perhaps that is the issue?

Just as a side note, my electric shower also needs a lot longer to give hot water early in the morning than it does during the day. Of course, that may just be my imagination on a cold, dark morning!!

Also not a plumber, but i've always been led to believe the sounds you are experiencing are caused by trapped air in the pipes. Try turning off your main stop-tap, turn on all your taps until everything is emptied and then turn on again.
However, if the bloke upstairs has the same problem, you may both have to do this at the same time otherwise you are just pushing the air backwards and forwards between you.

That would be because your water supply will be colder first thing in the morning than later in the day when the ambient temperature is higher

Can we try and recruit a few more SUFC/ Tradespeople as I feel this could become a very useful topic.

 

[Cricko]

Good idea Dave I will make it a sticky somewhere.

 

[Berrichonne shrimper]

Good idea in theroy but you end up with lots of diy experts giving bad advice

 

[Cricko]

I agree Tone, but if it helps people with problems and others need help in this tight economic climate it is ok, of course we cannot be held responsible for any bad information tendered.

I agree. How a a thread for medical advice instead?

My lawyer disagrees and will be contacting the owners in due course regarding the artexing advice XXXL16 provided some time ago.
