I am thinking of upgrading our boiler and I have had a few installers out to quote and they all seem to either push their favourite boiler whilst knock the competition and then all mention the long warranties. I got the impression they were only interested in fitting the boilers, the ongoing support was not their concern. Now this leads me onto the next point - has anyone come across a manufacturer that tries to weasel out of Boiler repairs by blaming the installer? I know for the warranty to remain valid it needs servicing - but after having my boiler serviced - it was a 15 minute job, he put some probes in and said its running efficiently nothing else to do. So how can manufacturers provide warranties if they cannot determine who fits their systems and who actually services them?
