What i learnt from this video is to not leave a plumber alone with a pen or pencil. They will draw on anything 😀

[@aserta]

I restored a 1924 house with indoor heating, cast iron everywhere and copper piping. When we took the radiators off their mounts, we found the plumber master's drawing for his apprentices. Full sketch, complete with calculations and numbers, all in that nice writing that everyone used to have.

Plus 1 as was also taught that many years ago when I was a heating engineer apprentice some 30+ years ago , indeed those small tips really help , if the boiler had a high limit would combine the cold feed and vent , really made the world of difference cutting out a H system of airseps, or if the system was ok would pressurise it , normally doing 1/2 bar per floor , also done the same with back boilers after fitting the high limit kit, another thing I couldn’t get my head round for ages was the wring , then all of a sudden one day it clicked , blimey it made a huge difference when fault finding , alas had to stop working due to a severe back injury , all the heavy lifting caught up a and ended up with plates , screws in my back, really miss the industry , another reason I really enjoy watching these videos , blimey I’m waffling again, lol, thks again, stay safe and well

I experienced the same thing with a heating system in Alaska. We used a pump, tubing, a plastic tank, and acid to clean the system and flush built-up scale that was inhibiting the system. We neutralized it once finished. Running the boiler over 130 degrees was the cause of the buildup.

[@gmac8032]

Finally!! I find another installer that puts valves under air vents, I thought i was alone🤣🤣 Another tip is instead of struggling with a plastic tub to catch water from radiator get a roll of 'Rubble Bags' fron S/F and use one as a 'Flexible Bucket' Another job well done and all for £50.00 a week, I'm amazed we do this for a living 👍

[@GrahamReid34]

My heating had the same issue, older house new combo boiler old radiators, ended up running Fernox F8 for 3 days, flushed the system, replaced 8 radiators as they were original and the cause of the rust and sludge, replaced pipe work and fittings and changed the boiler heat plate. Works perfectly now. All about prevention and honest heating engineers like this 👍🏻 cracking video.

[@richardlewis5316]

A really informative video. It showed very clearly why sorting a system can cost so much money because finding the problems takes time and experience. People often only judge a job on the time taken. I too hate working on tanks in a loft - because the loft hatch is so small and always dreading putting a foot through the ceiling!! Paste? no comment!! (never use)

Excellent job. There one avantage of removing blocked bits of copper pipe is they are nice and heavy and fetch a nice price at the scrap dealers. The only downside is that now your gas bill goes through the roof. My bill went up by removing air from the radiators.In theory the air takes up space so now your boiler is heating up a larger amount of water!

[@garethswaffs]

Better the gas bill than paying for electric rads!

[@laurencelagden]

Really interesting video. I’ve just done very similar to my sealed system. I bought a magnacleanse filter and left in connected with 2 bottles of MC5 running round it for 6 days. Everyday I agitated a few of the downstairs rads then on the last day whacked the boiler flow rate up to 80 for 2 hours while again agitating the rads. Dumped it all and refilled with clean water. Ran system for half an hour then dumped and refilled again with 2 bottles MC1 inhibitor. System so much better but not perfect. I’m making my own thoroughflush gizmo to mains water flush with the ability to reverse the flow rapidly. Might make a video if it works. FYI, I’m not a heating engineer or plumber.

Nah mate! I’ve had the Flamco ones fail and flooded an office once - NEVER AGAIN! 😂😂

[@pedrosmits]

@@plumberparts lol, never had that happened to me. But other companies make the same kind of stuff. BTW, like you flooded the toilet last week 🤣. Hope you feel better now, great video. 👍. We never install without a magnet filter, especially when the systems containing a fine mashed heat exchanger.

[@Lizzard-t]

Had flamco AAV Brand new out of box.lasted 2 weeks then it decided it didn't want to be a AAV anymore. Rubbish!

[@yxcvmk]

23:15 As someone from outside the UK: Why would a towel radiator have two valves? One must be hot side, and one cold side (return)? Why not just have one valve and make the other one like on the regular radiators? Then you could even set the proper flow rate, without having the risk that the occupant of the building will turn it wide open and mess up the hydraulics for the rest of the house. What am I missing?

[@SimonWatson-nx1kt]

There should always be an open valve on a circuit to stop the pump working against a head of water ... this non TRV rad allows that, it works like a bypass and logically is the best one for this purpose ... plus the two chrome valve look nice.

[@Dave5843-d9m]

I used a thermal store in my house. Boiler heated water in the cylinder with its own pump. Heating (with separate pump) circulated hot water to the radiators. A high performance coil in top of cylinder provided hot water at mains pressure. It just worked and the thermal store cylinder halved the gas bills. Only snag was balancing some radiators. The valves would whistle. I fitted in line ball valves to restrict flow rate. No more whistles.

[@hvacrwrld1402]

Can't beat a good problem system video. Thanks James.

[@plumberparts]

[@monkeyflyer410]

My favourite place to dose a system is a nice towel radiator like you used, but I've found it easier to siphon the water out from the top using a length of narrow hose. It's really clean and controllable that way.

[@worthexcellence9163]

some awesome soldering job, man Also, the video editing just keeps improving, it is great.

[@michaeld_aus_b]

nice documentation of your work. I learned a lot again. My plumber always tries to explain me everything, but he draws on a piece of paper. 🤣 Man I hope I do not have this sludge thingie in my pipes 😉 Over here we never use tap water inside the heating system: always distilled/soft water. My plumber has a special device/cartridge for cleaning the tap water, if he needs more than a few liter. Usually houses here do not have an automatic refill system and heating systems are not connected to fresh water directly. I nearly need no refill (in a pressurized system), the yearly plumber inspection was sufficient. If I wanted a refill system, I would buy a system with a softener for the tap water, still operated manually after checking pressure. With only infloor heating and no radiators, I hope to not have a lof of rusting potential in the system. Cheers from Berlin

Fascinating. American here, who is not a plumber. I don't think I've ever seen gravity feed systems here in the US. I've only ever seen pressurized hydronic systems. You also see lots of steam systems here as well.

[@MrPaulpph]

steam systems?! in housing? pls show me an example 😮

[@tookitogo]

@@MrPaulpphThe first apartment I ever rented had steam heating. It used baseboard radiators that would get scorching hot, controlled by wall-mounted thermostats. From looking at it, one could easily have assumed it was electric, but the baseboards had very hot pipes connected to them instead of electrical conduit. (Well, that and that I knew it was steam because they said it was. The apartment complex used a central steam plant for all of the buildings.)

[@MrPaulpph]

@@tookitogo Hilarious, thanks for the insight. I only know them from ships, but even there you'll have condenser heat exchangers for a separate HVAC-heating system.

[@tookitogo]

@@MrPaulpph Why is it funny to you? I think they’re fairly common for large buildings or complexes built before forced-air systems became common (which only happened once air conditioning started to come down in price in the 1950s and 60s). It’s not something you’d find in a single family home, where hydronic systems are dominant (for non-forced-air systems). One big advantage is that the radiators for steam systems are much, much smaller, and probably cheaper (they’re basically built like car engine radiators, with lots of thin fins).

[@MrPaulpph]

@@tookitogo I just could not imagine this being in use for normal buildings w/o specialised personnel operating it. I know quite a bit about steam systems but where I am from this is pretty much purely for industrial use since >100 years.

37:44 AAV - for me that thing decided to leak, actually leaked quite a bit. I only knew cause I was in the place the boiler lives looking for something else. Dripping into a bucket . Any longer the leak would have told me via the ceiling from downstairs. At first I had never heard of a AAV. Wow it’s amazing once you’re fully vested in finding out about and what something is and does, for me I became a nerd about AAV and wanted to tell everyone I knew something about plumbing (well just a AAV.) it’s actually a clever bit of kit and genius really once you know why it’s there and for- anyways I don’t shy away from stuff easily I’ll give it ago, what’s the worst that can happen stuff is already broke, i will gain experience and potentially fix it. (Eventually I tell the misses only take 10mins - like heck did it) so …guess what I have a jaguar boiler my. AAV was part of the pump jobywhatsit - and it’s a glow worm jaguar that is old - I know this cause parts for this beast is like rocking horse s**t! (MORE on this in a bit) so the AAV I removed the lid part with all the float bit all attached (looks a similar make to the one in the video) I just cleaned it . Replaced and tested. It leaked. I repeated the same again , nicked the kids toothbrush and cleaned with limescale cleaner . Which was what was blocking the tiny brass valve that looks like a bike valve. It was full of crud. Replace and tested. It worked and for costed me only a new toothbrush. I was potentially looking down the barrel of a new boiler, just cause parts of few and far between. But you and other you tubers are my new education on anything to do with day to day running of the home. You tube helped me so many times , keep the videos up! They are gurt mint. So the jaguar boiler so far fixed when possible - diverted valve rubber diagram thingy, circuit board main computer bit. Gas valve (eBay ) also did need a proper gas safe dude for that bit. I don’t have mag thing on mine, suggestions what would be best for my jag? (I do have space for it) make /model/ spec? Cheers ears !

LOL your a bit of a character . I love it! 😍 your heating system in the UK so so different then here in the US. we mostly have forced air heating, that runs on natural gas, tho some places back east use oil as a fuel. if you are not Familiar with a forced air system, it has a gas burner that heats a Plenum, and a blower forces air over it, and the hot air is pushed through duct work, with a vent in each room., there is a return vent with an Air filter , which pulls all of the cold air from the room, and this is the air that is blown over the Plenum. thank you for describing in such depth how a common hearing system in the UK works. tho I am an American, I found it very, very interesting and informative 😀👍I gave you a like and a sub!

Working with a gentleman like this is what used to make the building industry such a lot of fun back in the day, when you all learnt from each other and really wanted to do the best job possible for people. To coin a David Brentism "Having a laugh...while getting the work done". At one time everyone was concerned about doing their job as well as possible like this - there's too many under qualified people trying to make a killing for half a day's work, pack up get out, and never want to come back to sort out hiccups. The man is a veritable encyclopaedia of useful hints and tips and really takes a pride in doing things correctly. As far as leaving valves and labels for the next person to come along - The world can't say thank you enough. Anyone who thinks fitting nice expensive isolating valves and drain offs (under a radiator, in a lounge with white carpets - trolls) all over the place are a waste of money - never had the fun of crawling around in a mountain of dirty fibreglass looking for the inevitable seized up ancient stopcocks just to change a couple of taps, or turn off a cheap Ballofix, only to find it starts to leak - gawd bless you guvnor' !

[@plumberparts]

You’re not wrong Brad! 😂

[@gasmanrus]

Even though I’ve been doing this for 32 years I quite enjoyed watching this 😂 I’ve had a few open vent systems where the cold feed/ open vent H layout has been completely blocked even in 22. A couple of things I would add to your video if that’s ok. With the magnaclean I’d have used my I gauge hose and drained/ syphoned it out to add the inhibitor. Same with the towel rail. Once you’ve took the vent cap off just syphon a bit out of it. Also the way that underfloor was Teed in was not good. There shouldn’t be anything Teed in on the common return after the return from the cylinder or it’s very likely to suffer with back circulation where radiators will be getting hot when just using hot water only. Nice work 👌🏻

[@Finglesham]

I am surprised that you still use a blowlamp and solder. When I had a boiler change and moved to a pressurized system the guys had a pipe join machine using heat. Very neat and quick. They only soldered one joint all day. Frightening how such a modern house was so crapped up! Thanks.

[@tookitogo]

“…using heat”. Well that’s how all soldering/brazing works: you heat up the joint and melt in the solder. A flame is one way to introduce heat. I don’t know what device you mean, since your description is so vague. There are machines to fuse plastic pipes, but presumably you mean metal pipes. Are you sure it wasn’t actually a crimp system? In continental Europe and USA, crimped pipe fittings have significantly displaced soldered copper pipe for new installations (and for some repair work too).

[@norxand]

Great video, very helpful.

[@Hnkka]

This is why they install those sludge filters in the return pipe before the circulation pump. You dont use copper+phosphorus alloys to join copper pipes? Very useful because with them you can braze brass threads/parts too

[@Wiltshire-observer]

I’ve had similar problems with a pressurised system - used in a bungalow. There are manual air bleed valves in the loft on both the flow and return, but chasing the air out of the system if it ever needs draining down, is a total circus. I’m not sure those auto bleed valves would help in my case. Once I have the air out of it all, it runs sweet.

[@DaysOfDarknessUK]

When transferring from an open system to a closed system now pressurised by the incoming cold feed - how does this affect the hot water tank? Are the hot water tanks of differing standards - ie some designed to be pressurised by the tank in the loft (low pressure) and some designed to take the higher pressure of the incoming mains water pressure (high pressure). Ie will you pop your hot water tank by going from tank fed from the loft to closed feed from incoming mains? I need to do this that's all.

[@dinendale666]

You should get a small strong magnet and go around the flow pipes in the AC , blockages or restrictions are usually magnetite so not to hard to find.
