Boiler service

with schemes used in other countries, and showing ours works best.

Point of order....

Are these scale inhibitor dosing systems separate from the boiler? I have just had a combi (Veissman vitodens 100-W) fitted to an annexe and can find no mention in the handbook.

Water here is fairly hard and I plan to use a conventional ion exchange water softener.

Or the CO2 testers, used for efficiency measurement, working by chemical legerdermain:

Thanks for the interesting link - which lead me to this one

When we had the engineer check our 'oscillating' boiler, the CO level (when in the oscillating condition) was so high as to cause his analyzer to shut down to protect itself, and even then it was so contaminated that even after being left for an hour to purge it still wouldn't zero!

He said that under normal circumstances such a high level would cause him to condemn the boiler as unsafe, but since it had been the same since new (over two years) he kindly left it running. He intends to return when his analyzer is working again!

No

If by 'measuring safety' you mean investigating atmospheric CO incidents then, no, it specifically doesn't: we're supposed to call in the Gas Emergency Service Provider (formerly TRANSCO) (who, AIUI, also may not be trained in dealing with such situations).

We were trained and assessed on using them for combustion analysis.

Yes, re-reading what you said I think both your statement and mine are true.

Should be something about requirement to fit something in the installation & servicing manual.

Should be OK then.

Thanks for that info.

Can't find a UK supplier and suspect they're still a bit more professional (read costly) than I need. The ones I saw mentioned here before were a bit more basic than those, probably in the 20quid range for a basic test. I have searched but can seem to come up with the right search terms.

I initially set up the boiler using a hired analyser from a specialist division of HSS but they don't do them any more so I'm looking for something basic to check that the combustion is still within limits.

OK Ta.

Perhaps this will help?

No - it works. Soft water here. :)
