My boiler (a three year old Baxi Combi 133HE Plus) is making an awful noise when hot water is demanded. especially if the heating is off, but does make the whining/grinding noise even when the heating is on. I've found that filling the system slightly alleviates the noise, but it doesn't go...

I'm replacing our gas Central heating boiler(ferroli) with a new combi boiler(baxi). Dont worry, I'm having a gas safe engineer do the connecting up. My problem is that i think there is a small leak on the system as when the boiler is off, during the course of the night, the boiler loses...

My closed central heating system has been fine for years. 6yr old Baxi combi boiler, 11 radiators. One bedroom radiator was discovered to be full of air (more air than water I reckon), so I vented it. In doing so the system pressure dropped, as you'd expect, and the air stopped coming out, so I...

Hi all, looking for some advice. My pressure on the system rises to 3 bars every time the heating kicks in. then the release valve goes and dumps water outside (a very small trickle). there is no similar effect from the hot water however. I have just disconnected the filling loop and each...

I've just discovered that my Baxi 133HE Plus is losing water pressure on the central heating side causing a droning noise from the boiler when hot water is drawn off. When the water is topped up via the filling loop the noise stops, however I have had to top up the system several times in the...

Advice Needed.... I had a Baxi 105e fitted about 2 yrs ago... great boiler! Been decorating alot up to Christmas, the usual taking radiators off - Painting - Putting radiators back on... Got a prob today... Put a radiator back on yesterday - Pressure went down.. filled up using the...

Sorry blokes! It's a BAXI 80HE instant combi-boiler. The instant hot water type. When it cut off the pressure on the gauge read about 1.5 - 2 bar which to my mind is about normal. It definately didn't lose pressure or anything like that. Here's the baby...

Can anybody suggest if this is the same boiler as a Baxi 80 as spares for this make are silly prices compares to the Baxi 80/105 The PRV looks the same as ours is leaking and really needs changings as its dripping so losing pressure and switching the boiler, repressure the system its fine...

Ok iv had a Baxi 105 HE instant in for around 18mts now, the boiler came with a std 1 year warranty however as the installers were Baxi approved it came with a further year giving me 2 years warranty, over the last six months i have had to keep toppin up the pressure, and over the last week or...

Hi I fear i may have a small leak in my system and have read about these leak sealers on the internet. My question is do they really work and if so which is the best one ? I have a baxi 105e and was losing pressure I called an engineer and he replaced the pressure diverter valve ,(i was...

Hi everyone, Yesterday I noticed a small pool of water under my boiler, when I checked the condensate tank was leaking. The plastic cap at the top that the flexible hose connects to had cracked off. I've fitted a new tank and it's now bone dry. However I've noticed that the tank fills up in...

Hi Chris the boiler is a Baxi 130 he (same as the heading) I changed the pressure release valve a few months ago due to loseing pressure and it worked a teat, at the same time a few drips were coming from the primary flow switch so it needs changing anyway(i've just taken it off). I will fit...

Hi, please can some one give me an indication of what presure should be in the E/Vessel when the boiler is cold ? i see some people say 1bar, some say 0.5 bar, i just changed the Pressure relief valve as i was losing a little water through the pipe, i checked the P/Vessel and it had 0.5 bar in...

Hi, We've got a newly installed BAXI 33 HE A combi that is losing pressure. I'd like to isolate it to check for internal leaks before calling the engineer back out. I'd like advice on the correct procedure. I understand that leaving it isolated overnight should be sufficient. I presume...

I have had the BAXI Duotec Combi installed around 3 months with no problems, but over the last 10 days the water pressure has been consistantly reducing so that the HW & CH stop working around every 8 hours and I have to re-pressurise. :cry: I realise this is likely to be due to a leak...

We have just had a loft conversion / extension done where they took out the water tank in loft and installed an unvented indirect Megaflow cylinder. We have kept our old boiler, which is a Baxi Bermuda back boiler. For a while [about a month] all was ok. Since they have completed work in the...

Hi, Since moving into my 2 storey flat 3 years ago, I have had to top up the water using the filling loop below the boiler as the pressure has been reducing to below 0.5 bar. (I top up to 1 bar when cold) This summer I noticed a damp patch in the wall below a lot of the central heating...

Hi. I will be updating our old heating system in the not to distant future and have been doing a lot of research into different products, eg rads, boilers, programmers. etc I had kind of made up my mind that i wanted a vaillant eco tec 828 but when we had BG salesman round to give us a...

I have a 2 year old Baxi 105e Instant. About 4 months ago I noticed the system was losing pressure, alittle at first,then alot so I kept topping it up(the pressure went down to 0, then I refilled it to 1 bar (when cold)). There was no obvious signs of a leak (no damp patches on the ground floor...

We have a Baxi Duo Tec Combi which was installed in the house when we bought it almost 5 years ago now. Its been faultless all of that time, until early December 2013, when it began losing pressure and cutting out. Luckily we have boiler cover with Domestic & General, so I called them they...
