Thank you very much Derek, please can you do some faults on condensing boilers and if possible system boilers too. I done training with baxi and only now my eyes slightly opened. Your teaching skills are second to none. I am not English native and you helping a lot. We appreciate your time and effort. Please ignore so called pro engineers who criticize your hard work. They watching you always to improve skills!!! Thank you.
