After some preliminary tests, I will strip your boiler down, clean out any dust build-up, check the operation of all the safety devices on the boiler, check and if necessary adjust the gas pressure-the final check is carried out using an electronic device called a combustion performance tester. Once I have completed the service on your boiler I will then check and test your whole central heating system, radiators & tanks even the ones in your loft! (some heating systems don’t have tanks!).
