When your boiler breaks down, or you have trouble with one of the many other problems that can occur with your heating, it can be very difficult to know who to call. Although boiler faults can be costly, quick and accurate diagnosis of the fault is the key to cost effective solutions. For the last few years, all new boilers have been high efficiency condensing boilers. These are undoubtably much more efficient — but only if they are set up correctly. We often find that they need adjusting during a service both to ensure that they continue to run, but also to get the maximum efficiency. And, with gas costing more and more, this has become very important. The other vital action during a condensing boiler service, is to check the condensate trap is clear. If this fills with debris, the boiler may either stop working — or flood.
