Annual Servicing

Annual servicing is imperative for oil fired boilers, a poorly maintained boiler can very quickly lead to much larger problems and become very expensive to rectify.

At Miller Energy we offer a full annual boiler service where we strip down and clean your boiler preventing the troublesome build-up of sooty debris that cause most of the problems. During the service we also carry out a long list of checks to confirm that your boiler is running as safely and as efficiently as possible. Some of these checks include oil pump pressure, air inlet settings, replacement injector nozzle, correct operation of the remote fire valve, integrity of the flue, burner chamber, blast tube, baffles and oil line. We also carry out a flue gas analysis to check correct levels of potentially harmful flue gas, this also confirms the efficiency the boiler is operating at.


Sadly from time to time even the most well maintained oil boilers run into problems and breakdowns occur. With our professional yet honest and friendly approach we aim is to diagnose and rectify these faults as swiftly and cost effectively as possible for you. Contact us for more information.
