Hey Derek, genuinely thankfully for these. I've got my ACS in a few weeks and these are helping greatly with my preparation. I'm in for 2 days training before hand, but reading books can be very dull. Just a comment you probably won't even see as it's an old video. Just thought I'd let you know your work is really appreciated by us engineers. 🙏

Hi Derek I’ve noticed at 15 minutes when explaining open flue ventilation in a room , your final calculations are( 135 cm free area ) you didn’t take off the 7kw adventatious air! Shouldn’t it be 100.13 cm squared Love your dedication to educate new & old timers like me. very clear explanation of the regulations and why there implemented. All the best Rob👍🏻

I can not thank you egnough for your efforts 👍your a champian mate dnt let tail bearers put you down they are selfish people who dont want people to learn once again thank you sir👍.

Precise and clear explanation. I wish tutorials like this were about when I 1st sat my Acs. Flueing and ventilation was a pretty heavy subject as was pipe sizing 👌. The more you practice the easier it becomes. Like learning how to ride a bike, 2nd. nature. Plenty heating engineers use apps or vent calculation gauges now. 👍

Derek you are the best teacher anyone can come across i am very lucky to come across your video i was in the middle of my gas training and i was so confuse and i almost gave up from continuing the training and i told my centre i dont want to continue with gas rather i want to plumbing instead but they refuse and i had to continue with very little courage on the training but watching your video for the first time has restored my confidence as every thing is very clear with your explanation. Bless u man

Very helpful and made it easy to understand, but not sure how the calculation on the first example added up. Open flue ventilation. The 20.02 x 5= 100.13. On your example it added up to 135.13cm2. Which ones correct please. Keep up the good work as its very informative and helps with my training no end.

Great video. Very helpful to understand why you would require an outside vent. Whilst it’s important to understand the figures, I’m assuming in 2021, most people will be looking to purchase an appliance that does not require an external vent, especially in Winer!
@1414141x2 жыл бұрын
Most water heating appliances now are room sealed so no need to put holes in walls ! The conflict is trying to insulate your house as much as possible which does not support putting big holes in the walls so there is nice cold fresh air coming in for a gas appliacne ! But those type, though still to be found in older instatllation, are no longer made. Gas fires however can demand a lot of air, so it may be necessary to put vents in to the outside.

If your coming into the industry now, open flue appliances with vents are going to be few and far between. The last one I attended was about 4 years ago, In my experience its the cause of the most amount of friction with customers. The one I mentioned was a Baxi Boston boiler installed in a kitchen with no air vent fitted. The customer just about threw me out of the house after saying I didn’t know what I was talking about after I advised him it was unsafe to use the boiler. On another occasion with another customer, I got into another argument after a kitchen fitter had fitted a new kitchen, removing the air vent that had been fitted for the boiler and then boxing the boiler in tightly without any compartment ventilation. The boiler in question was an open flue Glowworm Hideaway. In many respects I don’t miss them.
