  2. Good Video's.
    Could you do one on how air/gas ratio valve's work (zero governor etc). There is no air pressure switch or burner pressure's to measure/test. Could you explain how they work and how to test there components?

  6. so if your combi hot water fluctuates, it could be a blocked heat exchanger… it could be a thermister, perhaps a blocked filter located 'somewhere'… so could be a few thing's.. that's 3 parts you have check/ at least …and or remove could be there hours and hours and still not find a fault.. and if you work for a company that expects 6-8 jobs a day… well your screwed aren't you.. sounds stressful to me

  7. Jon I promise I’m not going to watch anymore of your videos I’m worried for you ,I think what your doing is very admirable but you need to check your facts if you believe checking continuity has anything to do with checking the voltage you sir are going to hurt yourself or someone else please stop 🛑 your a nice bloke but your information is wrong
