I've a problem with hot water supply from my combi boiler as above. When a hot water tap is opened, water starts to flow, the boiler fires up and the boiler temp display goes up slowly to around 60 degrees, all as usual, and the water gets warm. Then, the boiler temp starts to rise very fast...

Cheers for the response. The house I'm renting at the moment has a Biasi Riva Compact and I hate it - the showers etc are great, but as soon as you touch any tap (hot or cold) the hot water loses all pressure. Perhaps it's just a crap boiler, but it's put me off the idea of a conventional combi...

folks, i would be grateful for any help here.... i have a baxi bahama 100 and the symptoms are as follows: when i turn the boiler on for heating, i'll get about 5 minutes and then the flame failure indicator light comes on and the boiler cuts out. i can restart it again with the reset...

Having got a handful of quotes to replace our old Ideal Elan 2 and switch to a combi system, I've narrowed it down to two. There's nothing between them on price but one is for a Baxi Platinum Combi 40 HE A and the other is for the Vaillant ecoTEC plus 837. We live in a 3 bedroom detached...

OK, has it stopped rising on it's own though when the system isn't on? If so then we need to move to the next step. If the pressure doesn't rise with hot water but it does rise when you put the central heating on and it goes over 2.5bar then the Expansion Vessel (EV) needs checked for correct...

Hi I'm so sorry if this has been asked before. I did a bit of a search but came up with nothing exactly like this. When I turn on a hot tap I get the store of nice hot water. The boiler IS firing up, I have replaced the diverter valve diaphragm previously when it wasn't firing up. It was...

Was this fixed? What was it? My Baxi 105HE, is needing an almost daily top up and my condensate pipe (NOT PRV) seems to be dripping more than it probably should. I sure with a daily top-up that I would have noticed by now if I had a leak under the floorboards. The boiler will lose pressure...

Hello folks :o Just joined DIYnot.com especially to post this. Hopefully as a means of returning the favour of some of the advice posted on here: I was losing pressure (usually 1bar) within 1 day of topping up my Baxi 105e. The pressure seemed to drop more when the central heating was...

I am looking for a bit advice. I have a baci 80e boiler and have had a few problems lately. I have had a plumber out a couple of times. Once when it wasnt firing up, pcb changed. Then it was losing pressure, recharged expansion vessel. Now when calling for hot water the pump light flashes. Water...

Hi guys. I was wondering if anybody could help me. I've been having lots of problems with my boiler recently. At first it wasn't firing for heating or hot water; I changed central heating valve and also the hot water valve as well, and found the micro switches were faulty. I changed both...

Thanks Tony, really appreciate your reply. Will mention communication pipe between boiler and exp vessel to BG. Whether the pcb is faulty or not, should the pressure gauge still fall to 0 bar when the system is off? I thought water pressure in a combi closed system stayed constant on the...

HI All, Ok, drained the boiler as advised, fairly easy, although i did find some water still came out when i took the flow swicthes out, so have some towel ready. Both swicthes had some black 'crap' on them, so i cleaned them and also the pipes they sit in. Put back together, refilled...

You`re gonna lose your gas fire if you upgrade :cry: you need 22mm pipes from your new boiler, any drops in 15mm (some may argue 10mm), not for me it`s prone to blockage. :wink:

Then 2 years later they'll sell a powerflush because the system is corroding. Hmm wonder how that happened!! numpties. Unfortunately in this situation the pressure loss is very slow. Losing 1.75 bar in 5 weeks may be an extremely small leak. However its very unusual to be on the pipework...

Hello, We have a Baxi duo tech 40 HE and two weeks ago we noticed that one of our downstairs rads was cold, the next day we lost heat from two more in the lounge. This continued until we lost 6 radiators downstairs. We had our whole system balanced in January and managed to get our kitchen rad...

Right then, I'm Proper Stumped and I don't say that lightly The CH on this boiler is fine, (a while back it had been leaking a little and losing pressure but I traced that to a small leak from the junction between the primary Heat Ex and left hand Flow Pipe, replaced an o-ring and all's good...

I fitted our new bathroom last year, and sure as with all DIY plumbing work there were a few minor leaks which got sorted out soon enough. I used the push-and-twist type plastic pipe connections throughout and since I made them up last year there have been no problems. We are about to...

We have a Baxi Ecoblue 16 Heat (tank, not a combi) boiler. We have found that if we bleed our radiators, the system will lose pressure and it's hit and miss if we can re-pressurise it. The last engineer we had out for a separate issue said the filling-loop is faulty (I'm going off my memory...

Would love some advice: I have the above boiler for about 8 years. Have renewed the PRV and it seems to have gone again - but with some clicking of the PRV is seems to have settled again re losing pressure - maybe some crap on the seal. But also, the Microswitch on the differential valve is all...

Hi All Im new here so go easy on me please, and apologies for the lengthy initial post :) We've currently got an old (very old!) Baxi back boiler with gravity fed hot water tank which is all well past its sell by date, so when we extend the house this autumn we intend on getting a new...
