I've lived in my current property for 10 years and have just put up with the fact that some radiators either didn't get warm or took forever to do so. I had the TRVs set properly, but most of the lock shields were open fully. I've adjusted them as suggested and now all rads heat up evenly. Can't believe how simple the solution was.

Sometimes i think the old systems were best but so unregulated per zone. This system is a marvel, however sooo many things to go wrong making the homeowner a symphonic conductor to his household heating system keeping that fine tune in check. I'm glad you tuned this system in this beautiful home. Thanks to the owner for being so gracious to share it with us.

I agree with not slagging off previous plumbers. We have all been there when you get plumbers block and can't clear your head. It needs a fresh head to visit the job..

“Don’t slag other plumbers off, but what were they thinking” 😉

You are a good man. What you said was true and so much more respectful of previous plumbers than I might have been.

Thanks James for such an easy tutorial. I balanced all my radiators yesterday and set the thermostatic valves to no.3. One warm radiator is now blistering hot. Thank you mate.👍

Never knew heating systems had so much going on...id use you all the time if i had a problem, you seem to be on top of your game

Excellent video. I don't have the knowledge or skills to tinker with my heating system, but you gave me the confidence to balance the rads and adjust the TRV's to the most appropriate settings.

Fantastic video! I knew next to nothing prior to watching this video about boiler systems and now i feel i have a good grasp on how it works. Thank you.

Automatic bypass valve was what you couldn't remember ! Great video. Nice to see some decent P&H engineers still exist.

My background was soot juggling as an industrial heating engineer but office blocks shared the same basic system as found in homes. Half an hour cranking down fully open lock shield valves and Bobs your dads uncle. Don't really miss cranking up three stage half a megaWatt oil fired boilers or warm air heaters. 👍 Regards from Cyprus. 💟

What an interesting and educational video. Each and every plumber in the land should be made to watch this one, and several times over for some of them.

It certainly is a great teaching tool.

Best heating related video that I have ever seen. Based on your video I have fixed the exact same problem that you had on this call out. Thank you so much, you are an absolute diamond !

I really enjoyed watching this. Even picked up some tips. I'm off to set my thermostatic valves now. Near the stat, leave on 6, all the others, set to around 4. Nice house too.

Brilliant video. I've not got anything as complicated as that in my house, but I always love to learn. I'm a Civil Engineer and was not taught plumbing. The pin check was great to know. More videos please?

So glad I found your site. You are a fantastic plumber. That appears to me (I'm not a plumber or HVAC guy) to be a complicated system but you are obviously knowledgeble with it. Thanks for a great video. I'm from the US so all this is very interesting to me.

Nice job on that. I wish I’d known about this in my old house that was a new build because the down stairs was always freezing because the rads never got that warm but upstairs it was roasting hot.

This is gold. Pure Gold.

Very interesting! It’s always enjoyable to see how things are setup and work across the pond.

Brilliant work m8, 2 add ins, check the gas rate of heat source so u know it is producing correct heat. Test flow and return at boiler for differential heat accuracy, will tell u pump speed if correct and whether u have system design issues. But really great video.🎉

Cracking video, just gone round all of my radiators that were all pretty much fully on and sorted them!

Very good informative and detailed video in balancing the heating system. Thank you

Well done for us people who get lost with rads hope mine get better after watching this

Thankyou for a really informative video. I think most of my trv's are at 6 and i never new about balancing the other valves so I will be going around and setting them all to a 1/4 turn.

Took all my TRV's out, as nobody seemed to shut doors, This was an excellent video thank you.

Good overview. We just had a heat pump installed (which is working really well) but a few of the rads were not balanced properly. Took me a while but I think I’ve managed to get a heat drop of 5C across each rad.

so glad I've found this video! Mate - you are a lifesaver! sorted out my system doing this - great videos also!

First view of you….really sound and whilst this is not my area of knowledge and practice, I found it really interesting and informative. I really liked your straight forward information and professionalism…..esp when referring to previous plumbers.

Very Informative video James, just saved us lots of wonga sorting my sons heating, eleven rads in his new house 3 stayed cold despite balancing, did the stuck pin check on thermostats, and that was the problem, sorted out with push and pull and a drop of wd40, a massive chuffty badge to you, and a thousand thankyous.

Cheers man - you’ll love my next video, a collab with Artisan Electrics (Lee and Luke)

Great video, you sorted it with no trouble.

I stopped using gatevalves for flow control e.g. on the primary return, back in the mid 1980's, they are not designed for that purpose, I use DRV's, a bit more expensive but virtually tamperproof. I would only reduce the flow temp to 60 deg.c if I knew that the radiators were sized for that Delta T. A good demonstration of the benefits of investing in a good thermal imaging camera, far quicker than using 2 Rototherms😊

Very well explained and thanks for sharing

Brilliantly explained , Many thanks .

Great explanation video. Its often the easy fixes that are overlooked, amazing how little flow you actually need to carry the heat in a rad. Have to say never actually thought about restricting the HW coil flow but makes perfect sense. Couldn’t work in socks get some indoor footwear 😂

Hiya James. Just saw the video with you and Roger Bisby and the noisy rad. He asked you when the baby was due, didn’t notice when video was made but just wanted to wish you and Emily all the very best with your new arrival! If the little one has arrived many congratulations🎉🎉 to you both.

Had the same issue on my ex council house. Main runs to front and rear of the house were 15mm supplying 4 rads each. Changed these to 22mm and things improved dramatically.

I had a cottage where the radiators furthest from the boiler never really got hot. Balancing improved it a tad but it wasn't a complete cure. It turned out the pipework was too small to get the heat to the 2 rooms. Replacing the pipes i.e. 15mm to 22mm cured the problem.

25:20 All fun and games when pin pulls out..Done that before 😅😂

I changed my TRVs a couple of years ago after changing the boiler. I now use the Hive programable valves which effectively make each radiator a separate zone. They also control the boiler when heat is required. These so far have made the house a lot more comfortable in that we can program heat to, for example, our bedroom and on-suite for an hour before we get up and the it's nice and toasty, likewise we can shut the heat off in rooms we don't use for most of the day and only heat them when we do. The app is not the best but it works. I'd be interested to see if you have come across them or used them. Also when I refitted my utility room I fitted a SureStop on the rising main above the normal stop tap. Having had a burst pipe a few years ago and my wife being unable to turn off the stop tap it seems worthwhile for emergency use. Again if you have used or come across them I would be interested.

Great video mate. Thanks for sharing. You've mentioned self balancing valves were not set correctly but you didn't show this in the video. Perhaps you could share when you get a mo? Thanks mate 👍🏻

As always, fantastic informative vid 👌.

Excellent and professional 5* mate.

Great informative video James and what a lovely property - so jealous.

Makes me appreciate my central HVAC system that much more lol. Thats a pretty complicated system with A LOT that can go wrong. I've lived 50yrs without heated floors and radiators and have survived just fine lol I know radiators were a common thing years ago and some places still utilizes them.

did most of this but also had issues with air so the radiator was hot at the bottom on a couple but well explained thank you

Such a tidy and well organised system, oh dear. And very handsome boots.

Fair play ,great vid.

One of the earliest things you learn as a heating engineer is that isolation valves ( gate valves) are not balancing valves, they can not be used to accurately balance a multi zone heating system, at best you get crude control on the last 10% of the valves movement

Absolutely brilliant video, well done fella! I was in the same situation with a north facing bedroom that is over a garage. The radiator never really got hot. It was also the furthest radiator from the boiler. I've just been round and balanced all the rads as per this video (most were wide open). What a difference this has made. Fantastic and thank you for de-mystifying rad balancing!!!!

It only needs one radiator to have its balancing valve fully open, to return hot water to the boiler and shut it off, not to mention starving the other radiators of pressure. The easiest method is to first turn every valve fully off, then open it a quarter turn. You can then start to balance things up, by adjusting the valves a fraction of a turn at a time, then waiting 30 minutes for the result. Needless to say, you have plenty of time for cups of tea and if things go belly up, just start again. I use the same method in large commercial buildings, where the boilers are putting out megawatts of heat. It is just a matter of keeping a clear image of the entire installation in your mind.

@@Horizon301. Before starting, bleed every radiator to remove any air and check the system pressure. Before turning the boiler on, turn every thermostatic valve to maximum and set all the lockshields to a quarter turn. Then switch the system on. Walk around as the system starts to heat, to check that every radiator starts warming up at the thermostat first. Then walk around every few minutes to check the progress of the heat across the radiators. Those that are hot right down to the lockshield within about 5 minutes are fine. If a radiator fully heats faster than that, reduce the lockshield by a few degrees, while any that are taking longer, (normally the larger radiators) can be opened a few degrees. Leave for about 30 minutes, then to check. Feel the top of the radiator near the water entry, then at the exit valve. The temperature should be a few degrees lower, but not noticeably cool. Then you can fine tune the lockshield where necessary. When you have finished, all radiators will have water available when required and none will be running flow temperature water back to the boiler while starving others. If any radiator is not responding correctly, the thermostatic valve may have a jammed pin that needs to be replaced or cleaned. NEVER try to compensate this by opening the lockshield, or you will unbalance the system. Finally set the thermostatic valves to set the rooms to the desired temperatures. All this is an awful lot simpler than it sounds and you will develop a clear mental image of where the water is going. Once you have completed it a few times, you will feel confident to tackle any system, from a bungalow to an office block, since they all obey the same basic principals. Set up correctly, the boiler will have a cycle to match the load and you may then want to adjust the burner to prevent short cycling. This can save quite a lot or fuel.

It's a bleeding pest needing to bleed the radiators and driving the air out of the system but it needs to be done to get the most out of your energy consumption?

Gonna check the balance on my rads as I’m sure all mine are open a full turn. Probably why the ones in the front room which are furthest from the boiler don’t get as hot as expected with the stat fully open. A well explained tutorial thanks, and all in layman’s terms.

In my experience most lockshields are quite useless at restricting flow once they are opened more than 1/2 a turn from closed, so a lockshield open one full turn or more is as good as fully open.

James, I take it this does not apply if a TRV like the Drayton TRV4 is used where the balancing flow can be adjusted within the TRV valve and the normal lockshield end is left fully open. Underneath the big adjusting temperature head there is another adjuster ring that restricts flow by using a special key. If someone installed one of these previously and set the TRV4 to its lowest restriction then no amount of fiddling with the lockshield will increase flow.

Sigh - all ours are set to maximum - and very few of the rads are getting warm. Thanks James. Now all I have to do is get the Wife to watch the last 30 secs of this video ;)

I balance each radiator as a percentage of the largest, in relation to their water content. Basically largest radiator lockshield open to 80% with the thermostatic rad valve set for the room temperature 2 usually 16 degrees bedroom 3 18 degrees kitchen, bathroom etc. Many year's ago checked this method with a 10/11 degree difference flow/return across each radiator on warm up came out the same. The restrictor on the cylinder is usually 1.5 turns open at the point where it goes quite. I won't tell you what Mr Combi says about the balance valve on cylinders as it goes against everything I was taught, many year's ago and that would be criticising. 😀😁😂

Love your point about the TRVs most people just use them as an off and on dial instead of setting them to 3 and then adjust them (my mum has a habit of covering them with stuff so they don't work correctly until I got smart TRVs that support remote sensor in each room (and I locked them so spinning them doesn't do anything) Probably the first KZread video that I've seen where they tell people how to actually set the radiators up my boiler is pretty old and doesn't have a bypass valve so we do have one radiator that has to be fully open (i recently went with smart thermostatic upstairs valves 1.5c lower then downstairs downstairs control by the thermostat we have an open plan house (all the radiators are set to full open downstairs due to open plan) G The temperature mechanical thermostat should be +/- 1c max (not 5c) any higher it's faulty hive is +/- 0.1c from target witch isn't ideal as it can cause high boiler cyclicing (if the boiler doesn't have a cooling off period) a lot of new boilers do, strangely the alot of heat pumps don't (have to make sure the controller that runs the heat pump has it) hive has zero radiant heat learning (just fixed +/- 0.1c off and on from target temperature) nest is +/- 0.2c ish target temperature set (reason for ish is because nest uses a on the fly F to C conversion so it isn't exactly what you set it to especially if you use the app, like 21c can be 20.8c to 21.1c) also nest does have radiant heat learning (so works out how long it takes to heat or cool down and adjusts when it goes off and on) only thing I recommend is turning off the auto schedule

If you can get it really clean and Dry, you could try gap cement. Once you have it clean and dry run a brush with 'solvent weld' around the joint a few times then build up with 'gap filling cement' and let it dry for an hour.

Could you use your thermal imaging camera to follow the pipe runs under the floors? Perhaps by looking up at the ceilings?

Very entertaining thank you.

Great job mate 👍

just picked up on something you were saying when talking about the auto balance valve "the boiler likes a bit of hot flow returning to it as it helps with the condensing" my understanding is that the return to the boiler wants to be as cold as possible. it starts condensing at 55c (might be wrong on that figure, doing it from memory) flow return but.... the lower the temp of the return the more condensing it does. how does having hot water in the return help condensing? in my experience due to the proximity of the trv to the radiator TRV don't really measure room temperature, the heat from the radiator completely overwhelms them (i do have data somewhere to back this up too)

This video was very informative and helpful for me, had the heating replaced from heat to combi, was never told about how the TRV worked, I thought these were more of a water flow regulator, not temperature controlled.

@monstermonstermonster2983

7 ай бұрын

It's about both. Flow restriction at lockshield to balance, but the TRV completely shuts off the flow at its end when the temperature has been sensed. The Drayton TRV4 does both at the TRV end where the lockshield is left fully opened and the flow is restricted within the TRV head as well as the normal TRV shutting off.

Great video, and funny presentation, really enjoyed watching.

Great video again mate and something I'll definitely have a go at myself. A silly question tho if I can ask, the 'other' valve that allows water out of the radiator, how open should it be? And should they all be set to whatever opening it is? Many thanks if you or anyone can answer and take care 👍

"........ should be by the Toilet" 🤣😂 Priceless James!

There was me measuring flow and return temps on each rad for a 11 degree difference, and all I needed to do was wind down the lock shield valve and open it a quarter turn 😮

"Legs don't feel the cold" Truth. I've been wearing shorts in Canada. Been down to -30°C recently.

Legs don't feel the cold but they do drastically affect how to core feels. Best way to warm up is to cover the legs or add a thermal layer to them.

You mentioned the by-pass valve should "crack open" tp prevent the boiler from reaching boiling point and steam, surely the temperature sensor built into the boiler / boiler controls are there to protect against this.

Thank you! Cheers!

TRVs sort of confuse me when it comes to efficiency because using one is counter to thermodynamic efficiency. The way to improve efficiency is to reduce any throttling effect - basically increase flow - and drop the temperature of the heating water. It's hard to see it on a domestic system quickly but I was an engineer on a steam VLCC way back and we burned around 160tonnes of fuel a day. Given that's a considerable amount of wedge being burned, running a high pressure boiler as efficiently as possible makes a huge and very quickly noticed difference. So, as we achieved the desired cruising speed what we did wàs gradually open up the main steam valve whilst at the same time drop the boiler temperature and pressure with the target being a fully open steam valve to the main turbines and the boiler pressure matching the desired speed. It saved a lot of oil per day. So when I renovated my house I ripped out the entire heating and water system and replaced the lot. I used more and bigger rads than required, used bigger pipework wherever I could and and reduced any throttling effect as far as possible with as many radiator valves fully open as I could get. I then set the boiler to the lowest temperature allowed which it could be set. This is the most thermodynamically efficient way to heat water.
