Brilliant Video 🔥👍

Great vids keep them coming please.

Thanks Roy and Alan brilliant very informative

Am planning to do plumbing in collage, I think I’ll enjoy it hopefully 👌🏼

Great video. Can somebody please explain what the consequence of the live switches for CH and HW being connected to the fuse spur are please? From my understanding the switches are usually made from the cylinder stat and programmer so how could they possibly be made from the mains current? Is this because it is in a classroom and there is no room stat and cylinder stat connected in the system therefore meaning that the live switches have to come from an alternative source - in this case being the mains - in order for the boiler to operate for demonstration? Also, is there not an increased voltage and therefore amperage being supplied from the mains which would damage the circuit? Clearly not but how can that be the case? I thought that voltages between control components are lower than 240 V. Any answers would be greatly appreciated.

Great video. Very interesting 👍

Brilliant vid. Thanks

excellent vid guys, helped me a lot many thanks

Amazing

Hello, on the hydraulic diagram of my boiler the differential pressure valve carries three pipes. One pipe is connected on the delivery pipe of the heaters, the other two pipes are connected on the pump suction. Can you tell me why two pipes are connected to the pump suction? Where can I send him a photo? Thanks

thank you soo much it worked

just watched , great to see Roy go through that . its got me thinking and ill have a go when servicing etc .thanks lads

Another great video👍🏻

Hello Alen thank u for nice videos. My question is if a gas engineer want to install a new boiler where no electric and can a gas engineer can do wiring and connect or the engineer Ned to be qualified for electric work

Hello, you are giving very good technical information. I wish you would add the explanation feature with Turkish subtitles, I don't know English. I write this translation to Google as an English translation and send it to you. We would be very happy if you add Turkish subtitles to your videos.

your non contact detector was rated 200-1000volts? it was my understanding they were required to go down to 50v?

Very good video

I use an auto ranging meter for £60 it’s been great.

Hi Allen How can we find the resistances chart if MI does have ?

Hello, I have some questions regarding the ground wire (yellow / green) in a boiler: 1) Can I have problems starting the boiler if the earth wire (yellow / green) is not correctly connected? 2) Do the two electrodes, the ignition one and the sensing one, close the circuit through the ground wire? 3) With which instrument can I test an electroto to see if it is good? Thanks

Nice one 👍🏻

🤩🤩🤩

belt, bracers and a piece of string 😂 Good video gents.

👍👍

Is the boiler on?

I'll just stick to my fluke voltage stick and fluke 117
