hot water

Hi, I have a Valiant 824e boiler which has recently started with a problem with the hot water. After turning on the tap (or shower in my case) the hot water comes through fine, but after a minute or so the boiler flame goes out and the water drops cold. If I keep the tap running, the boiler...

Sorry for such a basic question. The cupboard with the hot water tank and the cupboard with the non-combi boiler are a mess of copper piping and I am trying to make sense of it. I want to replace a washer in a downstairs hot tap. There is a pipe that goes to the loft. This pipe has a valve in...

So I replaced my bathroom sink tap a couple of weeks ago due to my old one breaking. (The plastic square protruding part of the mixer cartridge on the old tap snapped, could not source a suitable replacement.) Got my new mono mixer tap from ScrewFix and since fitting it, I have noticed an odd...

Hey :-) I wonder if anyone can offer some advice. My combi boiler isn't providing any hot water. The pressure is fine, the thermostat up. It's on, electricity is supplied and pilot lit it's only 3 years old. The gauge on the front is saying 20 degrees but doesn't go above this. Is there any...

Morning Guys, I'm looking to install a word-burner / central heating with thermal store as our only heating system (don't have any other cost effected options). Finding it very hard going getting reliable info on such a system, just wondering if anyone has been down this road and could share...

Good morning all. We've just moved house and noticed that the HW Cylinder Thermostat was only set to 50 deg C and the hot water didn't last for long. I've raised the temp to 60 but now we are getting really loud noises coming from the airing cupboard when the heating has been on for about 1 1/2...

We just changed to a combi boiler a couple of months ago. I am finding that we have to run the hot water for up to thirty seconds before it gets hot. Sometimes it runs hot then cold then hot again. It's a brand new boiler. Is this typical of combi boilers (I have never used one before)?

hi, firstly a bit of back ground. a couple of weeks ago the hot water pipe under our both blew off (due to the chap who fitted the bathroom before we bought the house not tightening a compression fitting properly) anyway this led to the hot water pumping out under the bath for around 20 mins...

Just had the though the other day that, as hot water from combi boilers does not normally get exposed to any air and is always under pressure, is it technically safe to drink? :D Not saying it would taste nice or be a recommended thing to do though! Regards: Elliott.

My boiler is 11 years old (the system was power flushed then). Just recently the hot water started to cut out. I contacted Vaillant who offered a £300 fixed repair contract. I have had two visits. On the second visit the diverter valve and plate heat exchanger were replaced. The first visit the...

Hi, I have moved into a new build and have a strange problem that the builders have tried to fix for weeks, hope someone can offer a solution! The system is a Vokera Mynute boiler with pressurised hot water tank and 2 heating zones. The hot water tank also has a solar thermal coil installed...

Hi all Re-plumbing a 4 bed, 3 bath house as part of a renovation and I am trying to figure out of a Secondary Return loop is worth the extra work? The longest pipe run from the tank to outlet would be about 18m. If we made up a secondary return loop the total pipe length would be approximately...

Hello, I have a Combi Boiler (Vaillant Ecotec Plus 428) and an Unvented Cylinder (Vaillant uniSTOR VIH GB 180s). Since yesterday we have no more hot water in the house, it comes out cold or luke warm. But the heating works fine. When a hot water tap is fully opened, the boiler reads S.30 (no...

So begins my sad saga. Like most of us, I like a problem and the satisfaction of solving it and felt capable of doing so as I have had some plumbing experience (Pre Corgi) and have, in fact fitted a complete system around 20 yrs ago (Tho my mate, Bill the Plumber did the final checks) Here...

Hi All, I am thinking of replacing my wired Honeywell programmer and dial thermostat to a Hive V2 and would be grateful if anyone can confirm a few things! I have a separate hot water tank. I have attached a few pictures of the wiring of the programmer and dial timer and labelled the photo...

Hi i have a very old Vaillant and its done me very good service but now go a problem When DHW is demanded the boiler does not fire up at first I thought it was the differential valve not sensing the water pressure but the pin was moving and the micro switches were going over the CH is fine but...

Hi there, Hoping someone out there can help me. I have a vaillant ecotec plus boiler No hot water No central heating Loud clicking noise coming from boiler Display is flashing between 0degrees & 0.0 bar When I hold down the minus key to check actual pressure it says 2.5bar Pressure gauge is in...

Good afternoon everyone, In a bit of a pickle at the moment and it's a bit of a long winded explanation so please bear with me. Recently purchased a new home and everything was working hunky dory for about a week. I decided to do some decorating and installing plug sockets so needed to work...

Hi All, I'm replacing an old dishwasher that came with the house - it looks like something from the 80s! It's a Cannon Hot Fill 8s. This means that there is a readily available hot water 3/4 BSP inlet hose (and drain). Looking online I can see that there is very little choice for a new hot...

Hey guys, Having issues with a worcester 28i junior combi. Heating is fine but when the hot water is in use it stays hot for around 30 seconds to a minute than runs cold. The boiler does not lock out. If the taps is then closed and re opens the same process happens. Hot for a short while than...
