Heath exchanger busted

solovei72

Hi to all
I would like to ask a question in regards to the gas installer particularly about the gas boiler.
Here is the overall story: gas boiler is 4 years old; Baxi Megaflow is the name of the brand. About a half year ago it was kettling so we called the gas installer to check it. He checked it and say there was no problem at all and in order to stop kettling I should turn the temperature down to 56 degree, not more than that. Ok I did that. Last week the gas boiler got an error 133. He came back and checked it and said that the heat exchanger is busted from over pressure because the inlet valve was open and it got over pressured.
My question is: can a steel gas exchanger get busted from house pressure? As the boiler gauge always shows no more than 2 bars, and even if the boiler has been over pressured, the overpressure valve on boiler schould let water out if more than 3.0 bars. Your opinion please.
Thank you

E133 is an ignition failure or interruption in the gas supply fault . Nothing to do with a blocked heat exchanger . Chances are heat exchanger is blocked though as kettling problem was not solved in the first place , reducing temperature is not good enough. Your installer obviously didn't flush and treat the system at time of installation .but back to e133. Make sure you have gas or if you have a pre pay meter that it hasn't locked out . You need to get an rgi that knows what he's at really and can advise you on your next move . Post your location and maybe one if the lads here will be near by and can help you out.

The gas installer say heat exchanger is busted because of the overpressure, and now he want to replace new boiler. That’s why ignition failure came because too much water inside. From your experience is possible that a 4 year old heat exchanger get busted from house water pressure, as I remember system pressure was all most always near/above 2.0 bar? And why is not possible to replace only the heat exchanger insted of new boiler?

If the heat exchanger was busted then you would have water pouring from the boiler . This is in no way related to an ignition fault , he hasn't a clue what he's doing IMO from what your telling me . A heat exchanger can be replaced but they cost as much as the boiler in some cases. 2/3 bar pressure would not "bust" it either. Get rid of him before he causes more problems.

Pm johnniek on here , covers that area as far as I know.

Just to add, is water flowing from your condensate pipe,...I've seen that with burst heat exchangers. As egass said, get rid of him. He obviously never flushed your system initially

He see the inlet valve was open, that why he came to idea that heat exchanger get busted because of pressure but actual even myself I didn't came to this idea to check condensate pipe. After boards/internet research, on Sunday when I was looking at condensate pipe, not easy to see is from road site, there I can see that it was leaking from long time just now it start so much that fire can't get on. First time he say that he will change that part through insurance, asking me to tell the insurance representative that the boiler is 1,5 year old. Then I call back second day asking what is story with fixing he came back to the house looked at boiler and say that is not possible through insurance, and need new boiler. Looking on Ebay I see heat exchanger for sale new one same brand.

Dtp1979 I need more question to be answered and I'm not sure to ask here because not breach forum rules.

Ask away. Just don't mention any names and you should be ok

That's a good point , never thought of that !

Funnily enough cause I was just at a boiler that was losing pressure and that was the cause!

Yep. Took the condensate off the "acorn" pressurised the boiler and closed the 2 valves. It Filled 3 bowls of water and pressure down to 0

OP as long as your questions don't relate to you undertaking gasworks yourself, ask away.

If your heat exchanger is really bust after all, they are so expensive that a boiler change won't be far off, last time I priced one.
Your system will also need a full power flush with either the repair or the replacement.

There is a few lads here that cover D15, sure they will PM you over due course too if you request it!
I cover it too, but am tied up for a week or more, so no real use to you either.

You are right about powerflush. As I remember even 4 years ago the gas man he didn't do a proper power flush at the time when replaced a 14 year old boiler with the new one. He is a registered gas insaller and last time he serviced the boiler he looked at it for 10-15 mins and he went. That is big problem for me I didn't know what he told the landlady but yesterday evening I received an sms saying I had a huge part to play in the boiler breaking and therefore the enormous expense she had to incur myself. The most important part of the story is that the gas installer man put the old boiler in the back garden and took apart the inside and the PCB (circuit board) he took it out and put it on fire to make it look as if it was burned inside. This weekend the land lady will come to see and as from my previous experience when I was said that the boiler is rattling/kettling she said that the gas installer man said it is working just fine. I asked her do you believe him and she said she does. Now exactly the same is happening she believes him and what he says. I would like to prove that it is not my fault. How can I do that?

Print off your responses.

Where's the rest of the boiler gone too, pump, gas valve, fan, burner, thermisters, flue thermister, overheat stats, flow switches, PRV, spark generator, some of the loom...all stripped for use on another appliance no doubt (hope he paid for them)

esox28

That's about €600 of parts gone to the black babys.

Op is that statement fact that the plumber deliberately burned the boiler in order to justify replacing it to the landlord, like was the burst heat exchanger not enough.

Looks like a promax, i someone was asking are they any good here, lol.

solovei72

Yes Dgobs &esox28 Thats what I meant the gas installer did this on purpose to get the rests of the parts from a 4 year boiler. I'm sure this is not the first time he has done something like this and in return other people have to suffer the consequences. In November if he serviced this properly then maybe it wouldn't have come to such a big issue. What other gas insatallor thinks about doing such service?I was thinking of making a complaint to the RGII or reporting him to the National Consumer Agency, what are your opinions on this?
