Combi Training School

Entry qualifications: C.O.R.G.I. or ACS (CEN1 + CCN1)

This is a one day course designed for installers who want to improve fault finding servicing and repairs for their customers or maybe change from installing and move into a servicing career and for new students coming into the ‘Heating Industry’, who have little or no knowledge of Combi boilers; no experience is necessary.


Why does a pressure gauge rise to 3 bar and fall back to 1.2?
Expansion vessel, faults and repressure.

I will show you how to conduct an Electrical Safety Test and find the fault safely, and correctly with and without electricity.

You will be able to dismantle and reassemble the boilers at your own pace but always with supervision, use your own tools and spend a friendly informative day with us.

Learn how to use a multimeter and understand why Ohms are so important, spend a day with someone who has been repairing Combies for over 20 years and still does.
