Intergas...but which...

[bernardgreen]

Almost 3 million made and so far mechanical failures equal none

None reported. Are you 100% ( I will accept 98.5 % ) certain that none have been scrapped along with the rest of the boiler when repair cost was too high.

resident Google King might have found one

There is a better source but it takes a while to access it via e-mails.

That is not the same question is it?

I imagine that my source is better than yours

Only 8f you want to overcomplicate things

Or stop scalding.

Bernard, under what circumstances do you envisage this catastrophic event?

The Titanic was not supposed to sink. Are you familiar with Murphy's Law?

It is easy to say there have been no failures if every unit produced can be accounted for. Would you or Intergas be aware if a heat exchanger failed with water pouring out and the customer had called an emergency plumber who then replaced the whole boiler with something other than an Intergas item ?. Only if a company has an enforcable policy that requires the return ( or notification ) of all defective items and none have been returned ( or notified as failed ) can that company state that none of it products have failed.

That said the Intergas heat exchanger may be as good as it is claimed to be.

Perhaps you could advise Intergas where they are going wrong and why they have such a high failure rate of their HEXs.. I forget how many have failed to date.. I hear what you say about having to tighten screw terminals, that is why the trend is towards spring loaded connectors such as those from Wago

You know the argument is lost when you start clutching at straws Bernard. Just about the only time Intergas boilers get scrapped is when someone that isn't familiar with them gets involved.

Very difficult for people to PROVE there hasn't been a genuine mechanical failure - far easier for you to prove that there has been; if it exists, perhaps your better source could help you out there..................

He still hasn't said how the sensor fails to on. He's pretty adamant it can.

An interesting position to be in.

 

[bernardgreen]

Did you miss this Dan. Perhaps I should add that semiconductors such as transistors can fail in service due to voltage spikes from high tension ignitor leads that are close to the leads connected to the semi-conductor.

Flow Sensor 844797

Three wire lead so quite possible an active sensor and not just a micro switch.
T shaped so quite possibly a paddle in the flow,
Unlikely to be an opto sensor with the paddle arm breaking a beam.
Possibly a Hall Effect sensor detecting a magnet field affected by the paddle arm.

If the sensor is active then the output from the sensor will have to be switched by a semi-conductor device and that device might go open circuit or short circuit.

I am reminded of the, no doubt apocryphal, story of the Rolls Royce owner whose car broke down. The vehicle was sent to RR for repair and eventually returned to the owner. Weeks went by and no invoice was forthcoming from RR. Eventually the owner phoned RR and asked when he would receive an invoice. The person at the other end told the owner: "Sorry sir, but our cars do not break down, so we have no record of any repair being carried out to your car."

But they're no where near it in the Intergas design??

If you are willing to allow theoretical possibilities then anything can become dangerous. Perhaps you have watched too many final destination films Bernard??

And I am reminded of the Internet Service Provider who set up an Online Fault Reporting system.

After 12 months they announced that no faults had been reported.

Actually a good mates Father worked in the customer service department at RR in the 70's. He used to tell a similar story that he swears was true about a rear diff that exploded in Germany on a Shadow 2. Apparently RR flew over a team of mechanics, put screens up around the car, changed the axle, paid the hotel off then denied the whole thing.

A feat rather more difficult to achieve nowadays with the WWW

I am also reminded of the diy forum that had lots of complaints about certain mods altering posts to suit themselves and having access to areas they had no business being in as well as deleting certain members posts and acting in a totally biased and unprofessional way


Nothing was actioned there either, just ask @Steelmasons

I didn't miss it.

Pebble dashing a post with all permutations you can come up with is not the answer. Keep trying.

My uncle told me a similar story. Drive shaft went in France , RR paid the hotel bill and when uncle went to thank the farmer who had towed the car the farmer denied ever seeing the car.
