BOILERS
Baxi carry out extensive tests on all boilers to ensure reliability.
IAN ROBINSON, QUALITY DIRECTOR FOR BAXI, EXPLAINS HOW BUILDING IN RELIABILITY DURING THE DESIGN STAGE GIVES BAXI THE CONFIDENCE TO OFFER BOILERS WITH A WARRANTY OF UP TO 10 YEARS…
Building in quality
Ian Robinson, Quality Manager for Baxi.
L ong before we make the decision to launch a boiler into the marketplace, we carry out numerous tests on the complete boilers and also their individual components. Extensive life testing can simulate aggressive, extreme conditions, in a laboratory environment. We test boilers flat out 24/7 for at least 12 months (the equivalent of five years under normal conditions), setting up worst case scenario conditions, such as air in the system or dry fire. Our laboratory has a wind machine, so we can test how boilers work in extreme weather conditions. We also have a ‘quiet’ chamber, so we can accurately measure how much noise they make when working. We also test single components to destruction in environmental chambers at different atmospheric pressures, humidity and extremes of temperature, from -20 to +40°C. And we carry out extensive field trials, so the boilers are exposed to different climates and conditions in a variety of
different homes and situations. Once we are satisfied with the quality and reliability of the boiler, we can start production. We test every single boiler as it makes its way along the production line.
and go into stock unless it has passed all the tests and has all its correct accessories and literature with it. Our first time good rate is 99.4%, but we still carry out single event analysis on every boiler that fails to pass the full function tests, using a root cause and effect tool to find out what went wrong. This is very similar to the approach taken by the British Olympic cycling team. Their manager Dave Brailsford’s principle was that if you make tiny improvements to each thing that impacts the rider, those marginal gains will add up to a much bigger overall improvement. It certainly worked for that team and it has also proved to be very successful for team Baxi!
Tests include: • Gas soundness test • Combustion soundness test • Electrical safety test • Hydraulic pressure test
When the boiler is completely built, we carry out full functional tests using water, electricity and gas, which takes about six minutes. The boiler’s barcode is scanned, and its serial number, test results, date and time of manufacture, which test rig was used, who carried out the tests, product information are all recorded for complete traceability. Every boiler has to pass every test before it leaves the production line. Before packing, the boiler goes through the kit scanning process. It can’t be wrapped
