this genuinely saved me £90 and a cold nights sleep - im a 25 year old woman who has never lived away from her parents so i was so scared and out of my depth lol! the relief i felt after spending over 5 hours this evening trying to fix my radiator, only to finally stumble across the video that helped is unmatched!! i am so, so grateful. thank you thank you thank you!!!!!!!

Being in the building services industry for over 20 years this is the best explanation of a basic radiator system. Fantastic and enjoyed the whole video. Thank you 👏👏

I've lived in my house for 8 years, a 3 floor town house and have spent a lot of effort trying to get the bottom floor lounge warm. After watching this i now match my room temperature with the middle floor thermostsat. Now that ive done it it seems obvious. Thanks for the presentation that changed things for me. Much appreciated

I don’t know what I’d do without Roger 🙌🏽… I’m renovating a 19thC house and learning on the job. I’m a sculptor so not totally clueless with materials, but suffice to say, with each new process I take onboard, Roger is the calm, real voice of experience I can rely on. THANKYOU 🙏🏽

Thanks for the tutorial. So after 25 years of DIY I finally know that a lockshield valve is not just for preventing air bubbles in your pipes when refilling a radiator (which I believed when I was told by a plumber about 25 years ago haha).

Wow! I just went from knowing nothing at all about central heating to having a basic knowledge about how it works in a few minutes. Great video! 👍

Many thanks, a complete eye opener. I'd never come across radiator balancing before, but it all makes sense the way you explained it. A task to complete before the onset of winter.

I’ve had radiators on and off the wall as part of the renovation as well as putting new ones in. Balancing is on my list of things to do, so this is great

OMG! Such an informative video! There are so many videos showing/telling you how to balance your system but this ACTUALLY explains how and why to do it! I understand it all so much more now. Thank you - brilliant tutorial 😊

Just done this and the difference is amazing ! Every radiator in the house is now piping hot where before I had 3 that just were not performing . Thanks for the vid , not worried about a cold winter now 😎👍

Great teaching for an electrician who loves plumbing stuff ( frustrated plumber) . Didn’t think about balancing the radiators but I can now see why you would. Very interesting. Don’t forget the automatic /bypass valve for systems with TVR’s on all radiators .

Excellent video. Keeping technical explanations and diagrams simple, helps to absorb the information, and aids in taking on the task. Brilliant! Thanks.

Thank you Roger! When I were a lad, I was taught the importance of bleeding radiators. Always checking them before the weather started turning cool for autumn. My step-dad did a great job of teaching my siblings and me to independent enough to not need to call in the trades-people for general work (but to also recognise when it was a good idea to call in the professionals). So over the years I am pleased to be able to say my skills have expanded a lot. This is a huge new piece of information that I never had previously. My current central heating system was installed a little over 5 years ago (replacing an archaic back-boiler and gas heater system). I was extremely pleased with the work done, and it has served me well. This weekend, I am going to check (and if necessary adjust) the balance. I didn't even know this was a thing! The system does have cold water storage and a cylinder with an immersion heater element. So hearing you mention more info to follow about such a system, I will be waiting with bated breath to see what more I can do to improve its efficiency. I've learned a lot from the Skill Builder channel, and am very grateful for the time you and your associates put into creating the content. So I'm off to invest in thermostatic valves to replace the basic 0-5 valves on the system (been meaning to do that for 5 years). And then to repair what I think is a sticky valve, which is causing my system to refuse to provide heat to the radiators unless the water cylinder also needs it's contents heating. 👍

Great video for explains the rudiments of a heating system. Be aware that when selecting raidiators the outputs manufacturers give are based on a differential temperature of 60 Celsius that is the difference between the radiator water temperature and the room that means the boiler needs to run at 80 Celsius . For every 6 Celsius we reduce the boiler water temperature the radiator selected size needs to be 10% bigger eg if we need a heat output of 1kw then a radiator of 1.1kW is needed. To run the system with a boiler temperature of 50 Celsius radiators need to be selected with a heat output of 200% so as to get a 1kW heat output the radiator needs to be selected with a 2.0 kW output. Unfortunately very few radiator manufacturers provide this information on their literature. Hope this helps folks.

Thanks Roger, very helpful. I've just replaced all my rads, thermostatic and lockshield valves and will need to do this before autumn arrives.Cheers!

Honestly, I’ve watched so many videos to fully understand the lock shield valve’s purpose fully and what happens when you close/open this valve. This is best video and the only one for me that explained it so clearly. What worked for me is when you said ‘water is lazy’ 😂. Amazing. I watched this video last year and watched it again now just now to remind myself about the lock shield valve. Thanks 🙏

Thank you Roger and the team for producing this video. That's me away to give it a go. Please keep up the good work as I am learning all the time. I am glad that I am not the only one who needs this explaining.

So having had two "professional" plumbers out to sort my heating and having been told there must be a blockage in the pipes I did some digging. Ended u0 replacing two radiators and still no solution. Then I stumbled on to this video and it all made sense. Had a go at balancing today and already its so much better. Going to spend a little more time soon and I'm.sure all will be sorted. Thank you so much.

Your info is magic , ive solved two problems already, fixed my troublesome motorised zone valve, and air in radiator , thank you .

Very knowledgeable person, was able to explain so any central heating Dumb can understand. I learnt a lot today. Thank you sincerely. By the way, I am 88 years old

This guy is an excellent presenter / teacher. Very clearly and simply explained. If you watch this you WILL understand balancing!

I'd halfway figured this needed doing but this really helps add some method to my madness! I was focusing on limiting flow rates, but adjusting the return valves makes perfect sense - thanks! 👍

Such an excellent explanation ... after 15 years I understand now why my front room radiators are not so hot and specially since I had the new efficient boiler 2 years ago. Thank you

Cheers! Absolutely superb video. It had been power flushed and have radiators on a separate run that wouldn't heat up. Balanced them all and it's working! Thanks Roger!

Thank you, Roger, for such a clear and simple explanation. God bless! 🙏🏻

as my dad always said,water finds the route of least resistance.great work roger.

Brilliant explanation of the working of a system! So glad I watched this video before bleeding my radiators. Many thanks.

Been trying to get a plumber out to sort out some of these issues on my heating system for 4 months now and just about given up. This video has just saved me a fair few quid! Many thanks.

Appreciated Roger! Thanks for sharing some sound advice. Cheers till next time!

Great information and help. Will use this method when it’s time for the heating to come on again 👍🏼

Thanks Rodger explained so the novice can understand how it works and how to sort out any problems I’ve been looking for a video to show me exactly what you’ve been on about for a while now so thanks a million

Every now and again, I’m glad our devices listen to our conversations..! My friend and I were talking about the heating today; I switch on the iPad and KZfaq and there is your video as a ‘suggestion’!!! 21 years I’ve lived in my house and the living room rad has never felt more than warm... Now having turned the ‘exit’ valves on the preceding rads to almost off, the living room is too hot! Thanks. :-)

Love this guy’s vids. No BS, just factual and to the point

Yet another excellent explanation in simple language. Even if not planning to carry out the work, these are so good as general interest and educational resources for a home owner and DIY enthusiast. Thank you.

So glad I found this video we've just lost my dad and he did all the radiators. My mum has a rad that is not putting out heat in the hall and this video has been so helpful I've actually learnt loads and found it interesting how it all fits together round the house. Thanks for the helpful video.

Great videos, it’s all depends on the installation of pipe work and number of radiators and the distance, a good heating engineer don’t cut corners and being tight on pipe work, so the balancing easy. If balancing doesn’t work, then clean your system and change the pump, because the pump can be weak. Excellent video about temperature differential mentioned there.

Brilliant video, thanks. It was actually entertaining as well as really clearly explained and practically helpful.

Thanks great vid! Never understood what balancing the system meant until I just watched this, well I'm a sparky aren't I? ! Thought my gaffe was getting a bit cold in some rooms, just watched this, and it completely explains why! All my return V/Vs on every rad were wide open :) So, i've closed the ones nearest the boiler a couple of turns, and it's made quite a difference already. It's too late right now to do the 11 degC check, I'll have another go tomorrow. I also bled the system tonight too, there was loads of air in one rad!

Fantastic video Roger! Balanced my radiators and blimey, what a difference it made! Massive thanks!

Been trying to understand what balancing was and been trying to suss out how you balance an underflow heating system with the flow meters, you have just made me an expert after your wonderful illustrations and explanation in balance and flow of water thank you very much Sir.

Fantastic, easy to understand video Roger, with some great humour thrown in too. Love it! Thanks for uploading :)

just wanted to say thank you, your vids are so clear and easy to understand and really helpful.

Brilliant explanation! Even I could understand it :-) Thanks so much!

Thanks so much for this video I found it really helpful. Your way of explaining things gave me confidence to tackle balancing my radiators, great video!

This is first house I’ve had with thermostatic valves, which allow still-hot water to return to the boiler. You’ve opened my eyes to why I’ve been having problems at the end of the rad run. I’m hopeful I can now fix it by adjusting the lockshield valves. Thanks very much, great video!

After just watching another vid about this,and being non thr wiser,I watched this and all became clear.Thank you.

Thanks for the Friday night entertainment :). WIll there be a part 2 where you mention the water cylinder and guidance around keeping one or more radiators open in the loops?

Absolutely brilliant video Roger, more videos like this please! Just starting my level 2 diploma in plumbing so very helpful for me!.Thanks!

Such a pleasure to watch someone with a true love for his craft , silky slick teaching skills too sir .. well done indeed

Great video! Think I understand as a lay person/normal homeowner. Thanks!

Thanks, wasn't aware that's how you balance radiator, using the 11 degree difference method. Appreciate the video.

Once again a mass of REAL info to help get things correct NICEONE FELLA😉👍

Another great video. Many thanks. Love your straight talking and clarity. You've also got a good sense of humour 😃

Thanks for posting this video I followed your instructions and other KZfaq videos just like this one it has done the job, my fat is a lot warmer and my central heating is not always trying to heat the flat. Keep up the good work the videos are very useful.

This is so helpful, love your videos on this channel. Thank you very much!

SORRY FORGOT TO SAY THANKYOU FOR THE UP LOAD I WILL NOW DO IT MYSELF ........

This is a great video as it is so clear and easy to follow - thanks very much. Always amazes me that the people who know most about stuff just make it seem simple. Those who don't just confuse you with jargon.

Best explanation/video on system balancing I have seen, now I understand what I was doing wrong. Thank you so much !!

I work in a school and was having issues with a few radiators, this did the job nicely.

Great to see you back Sir Roger, hope you are keeping well.

Best explanation I have seen of how it works. Thanks. Another useful video.

great explanation, I will be attempting this as I have to replace an old thermostatic valve on 1 upstairs so the system will need draining down and it will be a good time to try this, I may even get the one cold rad that struggles to get hot to work properly.

What a great bloke sharing his knowledge ..well done mate

Great video. Not at all confident when it comes to plumbing so this is great for understanding- plus the system in our house is microbore- an utter ball-ache.

Thanks Roger you have a great way to make it sound easy I am going to balance my ones today , and have a digital thermometer to test it out . Thanks for the great video.

Better than most lecturers in top universities. Well DONE and keep up the good works, as always!

Best explanation of Radiator balancing I have seen :) Thanks

Great video as always Roger. Thank you 🙏

Very nicely put together. I haven't touched the temperature setting set to max by the heating technician; but now I can see that setting it lower will hopefully make my system more efficient while putting less strain on it so that it's heated up more slowly.

Very good explanation Roger. Other guides say the upstairs rads tend to be greedier and need fewer turns than downstairs. I suppose it needs that bit of patience to get it right. I eventually got my own dialled in after replacing all the downstairs for new. 👍

Superb video! A job I've been wanting to tackle but wasn't sure how to go about it on a practical level. Just need to do it now!

Thanks for this - I had balanced all my radiators but then had an extension built - another shower, towel rail and radiator all added onto the existing infrastructure but not sure on which flowline! and since then we have had a lot of issues with the radiators. Trying to work out the flow sequence has hurt my head but just starting with the ones that get hot quickly is nice and simple!

Would love a similar series on balancing UFH manifolds. Seems a lot of principles from this video can be applied to UFH manifolds, but still seems a lesser known area.

What a wonderfully educational channel ! Subscribed after the first video, now onto my 3rd clip...Thank you !

Bang for your bucks. Great content well done Roger. A huge help in spite of your wiggly lines

Very useful video. I actually have a Baxi condenser combi and I've set it to 80 C and it's costing quite a bit to heat this old Victorian house. I tried setting the boilder to 55 C yesterday after watching the video and the house is still warm as before, so I'm hopeful that the bills might come down as a result. Also, I've never even heard of balancing the radiators - not even our plumber does it, so thanks for the tip!

Fantastic video. Got up in the middle of the night and cane across this video. Very well explained and entertaining as well. Now I must get back to bed to keep the lady of the house warm.

Brilliant video, ur light uses of humour make all ur videos very enjoyable to watch.

Absolutely love this. Thanks for your insight Roger

I've wanted to know this for years! thanks Roger the Dodger.

Great explanation of what the lock shield valve is actually doing to the flow of water! Now I get it!! Thank you!

Thanks for a great explanation and giving me the understanding and confidence to have a look at a cold radiator ! Cheers !

Thank you very much, sir! None of the others I watched, explained things nearly as well as you.

A great video. Well explained and now I know the reason why my grandsons room is colder than the others. Will be giving it a try.

Your way ahead of explaining than other vids I watched. Better explanation of the way the cold valve works, and what happens when you adjust it. Thank you.

You always impress me Sir. Thanks for the brilliant instructions. You have trained me on showers and heating system balance. What is next, I ponder.

You're a very good instructor, thank you!

Brilliant 👍🏻 Thanks for sharing your expertise, this information has helped me sort out my home heating system just in time before the cold winter ❄️🥶👏🏻

Thanks again - very helpful. I'm going to track all the pipework/rads to see the flow and balance the system.

Brilliant, this man can explain things in a manner even I can understand 👍

Great explanation for diy guys by somebody who knows what he´s talking about. Thank you.

amazing, I now know flow and return terminology, and the valve differences on a radiator. I absolutely love the skill Builder series. big thumbs up mate. please continue the series.

Wow, absolutely brilliant, so well explained, will be attempting to balance our rads tomorrow, thankyou

Nice video and easy to understand and also had a bit of a giggle. Keep up the good work.

Fantastic as always. Cheers Roger

Great explanation. So clear and precise. Thanks a lot

Great video. Clear, well edited and no Drabble. I’ll definitely start to test temperatures on flows and returns now I accept an 11° drop per rad and 20° in total. Thank you, FYI; I’ll focus on the 11° per rad and HOPE it’s 20° at the booafyer I’ve finished. If I get 11° at every rad, I’ll be happy. The 20° at the boiler will be a bonus. If you post more info on this subject please kick me in the temple (of my head I mean. Not the last crusade.) to ensure you get my attention, 🤭🔥✊🏼👀😋

Explains this very clearly. Excellent video

I can't wait to have a go at this! Brilliant!

A truly awesome video thank you. We're replacing an old loi boiler with a combi gas one and wifi vales on teh radiators. This video really helped us understand how it all works and how to balance teh system. Well done!
