Hi Chris seems like I was back in my old work life , as in boiler rooms be it schools , offices , factories etc . But you managed to sort it , which is not so easy for electricians who have been used to domestic work . To all those who are not so confident with this type of work , it’s not so hard as it looks . Just take your time to think about how the system is supposed to work . All the basic principles are the same , just on a bigger scale . And never be afraid to ask someone if you do feel out of your comfort zone , no one of any worth will think less of you , quite the opposite in fact . Chris is a wonderful ambassador for the trade, so you could do far wurst than follow his example . Best wishes and kind regards to all from an old retired electrician 😀👍👍👍

Took me right back to the good old days of industrial plant room work.. I don't know if you are aware Chris but the immersion elements are a back up heat source for the hot water cylinders (incase of boiler lock out, or gas supply interrupt) and they shouldn't be left to run continuously.. So the internal stat inside the immersion element should be set to 60 degrees and the control stats for the boiler should be set to about 65 degrees, & the only way to get this adjusted correctly is to bring the tanks up to temperature ie 65 degrees, then turn down the immersion element stats till they click off leaving 5 degrees (roughly) for the control stats to work in.. And so the immersion elements will only kick in if the main boiler doesn't and the stored water maintains 60 degrees according to L8 regulations.. Also on a system like this there ought to be a timed de-stratification pump.. Anyway,I always love your videos and it's awesome to see you doing some commercial/industrial work for a change.. Sending positive vibes buddy because your videos are always great fun to watch, so please keep em coming and I'd hate to see them stop because of the haters out there...

Good video - the chirping in the background had me thinking I had a feathered friend in my house. I preferred Commercial to Domestic especially to occupied Domestic.

Nice to see a sparks that knows how plumbing works. Makes a change.

pretty sure he's a qualified plumber also

For someone who’s transitioning from gas/plumbing heating to electrical , this is right up my street. 👍🏽

Hi chriss,as always,an absolutely superb job.ive been in a few boiler rooms over the years myself. I fell over things all the time.but was always warm.i enjoyed it ,truth be told, Keep on with the great vids.well done bud,

[@paulprescott7913]

What an untidy place. Nice to see you do something different.

[@chincono1]

Not a single criticism out of Cris shows he’s out of his league being in a plant room

[@paulprescott7913]

@@chincono1 i wasnt criticising Chris, i just noted that the place was untidy.

[@datsunruss]

Good video Chris - this was more like the jobs I used to get when I was on the spanners. Industrial \ commercial installations. 👍👍👍👍

[@ef7480]

Just to clarify, you have a permanent line to the thermostats and a perm line to each grey on the motorised valves. When th e stat calls it powers the brown for the motor which in turn closes the microswitch that powers the orange('switched live') to fire the boiler?

[@haydenuk02]

Excellent work and thanks for sharing this with us take care

Get yourself a bahco slim jaw adjustable spanner too! Great for glands.

[@roseironworks1393]

Finally.... welcome to the real world of electrics, this is what i do every day, and its a shite site better than ball busting in houses, way more interesting, and much easier to test afterwards.....

[@Cjrelectrical]

Yeah did this for 10 years bud before I was promoted to house basher.

[@effervescence5664]

The 5:10 "Safety Warning DO NOT USE!" would likely have been put on by the gas engineer to stop anyone powering up the plant before he's on site to check the combustion of the appliance as although they're factory set the relevant commissioning checks have to be carried out before allowing an installation to be used. Stainless tanks with the worst stats going. Nice job for not your usual realm of videos.

[@Cjrelectrical]

Yeah I’ve since found out the tag was from the old tank that was condemned

Lost count of the number of plant rooms I’ve been in over the years as a M&E manager, 90% of them were a cross between a skip, doss house and scrap yard.. My last words to any contractor doing any work was clean up after yourself... bit like p ing in the wind

Hope you wired through the high limit side of the stat first and then into the control stat . Good neat job nightmare plantrooms with limited lighting . Great job 👍👍

Fitted loads of those tank stats, they're awful lol. Plumbers always lose the gland pack lol. The dial is a nightmare to get back on, hardly any space to dress cables and the fixing screws are rubbish too 🤣

[@markpunt9638]

Nice job.

[@brendanfisher2528]

Great video, was confused with your explanation of the wiring, it should be Grey is permanent live. The stats only control the brown on the zone valve opening it and clicking the micro switch, basically sending power from the permanent live (grey) to the orange which goes to the boiler powering it up.. Is there any reason the plumber didn't do this? Or was it just with it commercial it had to be a sparky doing it? Loved the video! Was great seeing you do some commercial.. I'm a gas engineer from bradford

[@Jay369]

You could wire the orange as permanent and grey as switch live to the boiler. It's just a switch so polarity shouldn't matter. (???)

[@BULLEAD]

Agree with Brendan. The call from the cylinder stat should have been connected to the brown wire of the valve.

[@denkitney8865]

Made sense, after you explaned it all...lol PS did you have a small bird in there with you? 'cos I could hear it chirping in the background on the vidio.... 🤣🤣

@@Cjrelectrical but to be fair it would make sense if the grey's were switches and brown perm lol

[@GrenPara]

Good video thanks for making it. But I would have kept all the switchs together on the wall where they were. No Maintenance worker wants to have to search a room to find hidden switches. And while you and current guy may know where switch is others may not. Just my view.

[@Cjrelectrical]

I have marked the switches on the plant room map.

Looks like a ball ache of a job. Correct me if i'm wrong, but shouldn't the greys of the valves be perm live to the micro switch that switches the orange when valve open. and the browns are the 'motor live' to open the valve?

[@supersparks9466]

Correct

[@Cjrelectrical]

Yeah correct rectified after.

[@davey6024]

Was going to say on a 2 port the grey is the permanent. Had a job the other month and the installer decided to turn an y to an s plan and there was no bloody permanent live there in the wiring centre as a 3 port doesn't need one! Luckily had a spare core coiled up from the programmer in the kitchen to utilise.

[@stevecraft00]

I don't get it. They have district heat? That doesn't get hot enough? Surely that's a problem lol. Was that a massive cylinder boiler to the left of where you were working? I've been in a District heat plant room. There were 3 massive boilers that provide heat to 900 homes. But the gauges on the boiler output shows nearly 100 degrees and where it enters the tower blocks (up to quarter of a mile away) the gauges read around 95 degrees, with about 85 degrees on the return depending on demand. Some serious kit keeping all that going 24/7. They need to upgrade the control wiring so they have to write to 900 homes and tell them they're without hot water and heating for a day or so!

[@Cjrelectrical]

This isn’t a plant room supplying heat to homes buddy it’s a little different.

[@edc1569]

In commercial sites you can have waste heat which it’s sensible to use for heating, but it’s not not enough for DHW without some boosting.

[@greenyamo1321]

Shoddy plumbing work.

[@farmerdave7965]

It's a can of worms.

[@tomengineer1467]

Hi. Chris two power supplies feeding 1 system. ??? Control unit controls both yet both tanks are on two separate power supply from separate DB boards and no test to make sure there on the same phase…. All heating should be 1 supply and 1 protection

[@wyndavies5044]

The two immersion are two different system so will need two circuits, one to supply each one. Then the s/f spur controls the boiler setup. Whats the issue??

[@tomengineer1467]

@@wyndavies5044 the problem is valves are both controlled via switch fuse spur ….. so no not two separate systems …. Both tanks are heated not by boiler …. Boiler is there for extra heating…..tank 2 is own power but controlled with tank 1 control so no point two power supplies And again both tanks are from 2 DBS not testing to see if on same phase which they MUST not be Or risk of 400v as both tanks are connected via copper pipes if a short develops

[@Cjrelectrical]

Immersion heaters are only connected for backup if the boiler/gas fails.

[@jamesdyas542]

@@tomengineer1467 don’t understand they are earthed via the flex and electrical installation. standard way of doing it would be different phases for load balancing. You can get 3 phase immersion heaters.

[@tomorichard]

There is no real need to consider keeping phases apart. It’s a bit of a urban myth. It would take a earth fault on both appliances at the same time to even make the voltage present any higher than it would be anyway. Maybe would be concern in a domestic dwelling with two phases at one multi gang light switch. But certainly not in this environment.

[@kevinpickett7249]

Umm your connecting a heating system in a plant roon should you not put domestic electrician in a Comercial environment 🤭

[@B1cam]

Re cyl stat, you want the switch to close the higher the temp and open the the lower temp.

[@Cjrelectrical]

Yeah the tank was around 20 deg hence the click low down on testing continuity.

[@B1cam]

Cool.
