Baxi 105 HE Instant - low pressure in an hour - condensation

[kfoalty]

Have read several different threads so I think I may have arrived at what I think is the problem. The Heat Exchanger unit but hopefully someone in the know can help confirm.

Water is dripping (almost pouring when pressure is lifted to 1.5 plus) out of the condensation pipe (the white plastic one that comes out of the trap. Nothing out of PRV and pressure hardly manages to go over 2.

Have isolated the central heating system and pressure falls rapidly still, so no leaks in system.

If its the Heat Exchange unit , is this something easy to replace or are we talking a corgi engineer.

Thanks in advance

That does sound like the hex is leaking, most certainly not a diy job.
Corgi is no more when it comes to gaswork, what you need these days is a Gas Safe Register member, the successor of corgi.
Make sure you check the card which as the chap's name and photo on it; no card, no excuses; come back with card or find someone else.

Secondary heat exchanger gone, top right handside.
Part is around a £100 and depending on access around boiler it can be changed in situ ( bolted on from behind).
If not its boiler off the wall

i agree with namsag 100%

Why boiler off wall ???????????????

 

[namsag]

Simple we have no way off knowing if proper clearances have been left , if the guy has nimble hands/flexible back etc if close to ceiling or tools to get to bolt etc,

 

[baxpoti]

Have done quite a few never had to remove boiler from wall !

 

[namsag]

Done quite a few does that mean there is a fault with them then has baxi realised any info to yous regards failure rate

I do have to say that so far I have never had to replace any recouperator.

Having said that I dont go to so many with non stainless inner tubes.

I therefore conclude that its not a major failure point on any model.
