Thank you for your video. My radiator was working perfectly then just stopped working one day. After opening the return valve half a turn its working again and working even better than before 👍

In 15 yrs we have had British gas in on our service plan to service and every year we tell the 2 main room radiators don’t get hot. The answer is every time, Turn heating on and close down upstairs rad untethered said cold ones get hot. Then open them. Hahahhaaa 15yrs of shit. I saw this and every lock shield valve was fully open. So at almost 70 and disabled I had a go. Now every radiator is hot in 15 minutes. Even the 2 useless ones. All temp valve no set on low (1.5 to 2) and house is toasty warm, thermostat down to 20 degrees and magic. Thanks DIY Man your a star. Shame you have to be Corgi to device a boiler. Thank You.

Just as further interest! what I do is fully close off the lock shield valve on all radiators and fully open all thermostatic valves. Then go around each radiator and open the lock shield valve each by half a turn...then fire the boiler up sit and wait for them to stabilize then check temp looking for 12 deg across flow and return adjust necessary radiators by 1/4 turn until all rads are running hot, some may only need fine adjustment....after you are happy turn the thermostatic valve down to the required room setting....next make a note of each room lock shield opening on a piece of note paper for future reference...then go to the boiler and again look for 12deg across flow and return and if your pump is so fitted look for the same there you can on some pumps restrict the flow to get that temp return plus adjustment of the pump speed helps...do this and/or incorporate with advice given from G Man and you will have the most efficient system you can get.....one word off warning be careful of lock shield valves that haven't been adjusted i n awhile or you may end up with a leak.

That's certainly how it used to be done and works to get the desired heat, but having maximum flow will allow for greatest efficiency in a condensing boiler. Starting with all open a quarter will put a fair restriction on the system.

I learned a lot from this and having followed your instructions it worked! The biggesr radiator in the nouse has never got really warm but it does now.

I picked up the same tip working with process engineers in an R&D setting. Their reasoning was that, particularly in an emergency situation, you may not be able to tell if the valve was seized solid or resting against the stop if you happen turn it the "wrong way". So the risk was that by forcing it you could break it completely or cause a dangerous leak! By easing it back off the stop, even if it seizes you will still feel it hit the stop when it frees up again and know you turned it the wrong way. Sometimes you can't always operate a valve from an ideal orientation to instinctively turn it the right way first time, so that feedback can be critical.

Gary here from the UK I am an old heating engineer and you always want the heat to get to the radiator as fast as possible and stop the water leaving the radiator as slow as possible this allows the heat to pass from the water into the steel of the radiator, When you turn the heating on you walk around your home and put your hands on the pipes that feed the radiator, the one that gets warm first is the flow so Mark that corner of the radiator with a cross, I use a pencil to make the mark now you know witch is the flow, always turn the flow on full then back one turn . adjust the other end of the radiator or turn it down to close the valve, this slows the water leaving the radiator, as a rule the upstairs is closed more than the downstairs most of the other stuff you commented on was correct , Now that's the old ways on how to do it, don't forget to vent the radiators with the boiler OFF air in the system means less heat, Happy Balancing

My wife still says it. 😬

I made a tool for this. It's a tiny little USB powered sensor with 2 sensors on long leads. One goes on one pipe, the other on the other. The device sends the temp of each pipe to a database and then displays it as a graph. Basically you just attach it, turn the heating on and in 20 minutes check if you've got the right drop. Then keep looping around the radiators in the same circuit until they stay that way. Another useful thing to check is turning a few of the TRVs to 0 and checking you still have balance at the radiators and importantly the boiler in and outlet. After I did my radiators I left the sensor in place 24/7 on the link pipes between downstairs and upstairs circuits to give me a "mid point" view. It is nearly always 12*C delta.

This is great, thanks! Very informative and clearly explained. A thumbs up 👍

Been there. You have a leak past the valve stem. If you go near an old valve, the seal may give way completely so be ready with cloths trays etc.. Try twisting it on and off a few times in case there's a particle stuck in the seal. Try tightening the sealing nut. But if the seal or the valve body is worn, you will have to attack that by replacing the valve. Worst case a coupe of € for a new valve, plus isolating it to replace it. Eh don't flood the house.

The flow temperature here was about 70C - seems a bit high for a combi boiler. You should try reducing the flow temp at the boiler first and THEN balance the system as best you can.

If you are able to set a 12C difference between input and output using an infra red thermometer, do you still need to determine which radiator is 1st, 2nd, 3rd, 4th and so on in the system?

Great video, very informative. However, I'm curious about the temperatures - both absolute and difference. I though that return temp for modern *condensing* boilers was supposed to be about 40-45 degrees for max efficiency (not over 60C as per your example. Also, why only 12C temp drop between flow and return? I'd read that ~20C would be more efficient. So we'd be looking at about flow/return of 60/40, rather than 77/65?

@zx9mel

6 ай бұрын

Because the radiators in virtually every house were fitted when older boilers were in use at a 10C drop (70c in/60c out) means an average radiator temp of 65c to heat up your 20c room, and the rate of heat transfer is proportional to the difference in temperatures, in this case 45c. So people replace their boilers with 60c inflow, but a 20c drop to 40c outflow means the average radiator temperature is 50c so only 30c advantage so you’ll be waiting much longer for the house to get hotter.

Thanks for the great video. Silly question but at what stage from turning the heating on should you take the thermometer reading? I have two digital thermometers with probes, but wondered when the best point is to take the initial reading for analysis

Well just give the boiler time to heat the water in them depending on how many rads you have. Know your 1st rad 2nd etc . Sure give it 30 mins or so. Happy balancing

We have a very old system in our house. Well, the rads are very old. They are those huge, robust brass ones with the release valve on the side, near the top. If anyone has those and you haven't "balanced" them in years or every, I HIGHLY suggest popping down to a good plumbing supply store and by a few of those spigots/valves. I say that because when I first started doing this, as I loosed one to bleed off any air trapped, the spigot started leaking where the knob's shaft is. Turning it in and out quickly didn't work. So, no problem. I went and bought a bunch of these and good chance too. All of the other ones also started to leak after turning the knobs. They were very old. Now, I have a habit, during heating season, of turning them all back and forth a few times, releasing any trapped air and keeping them from any mineral buildup. Works like a charm now. I also now use our Thermal Imaging camera to quickly identify any problem areas. Such a great device for so many things.

Subscribed. Simple and straightforward, clearly presented and filmed. Thanks, in advance of my next task.

Thank you for these clear and straightforward instructions. :-) I've seen the 12K temperature differential mentioned in a few places. Do you know where it comes from? What is the reasoning behind aiming for a 12K temperature drop from in- to outflow? Thanks !

The temperature differential in smallbore heating systems i.e. those using 15mm and 22mm pipework, is normally 11 Deg.C, (Delta T) this is related to the radiator sizing, before condensing boilers came along then a system would be designed at 80 Deg.C flow and 69 Deg.C return, giving a mean water temperature of 75 Deg.C, you would calculate the heat loss of the room and refer that to the manufacturers sizing chart, you would then select the radiator to suit that room. When condensing boilers were introduced we mostly moved to a Delta T of 20 Deg.C which meant using a correction factor in the early days, until radiator manufacturers introduced mor sophisticated sizing charts.

@nicktecky55

Wickes specify the wattage of the radiator at 70℃ input and a drop of 10 degrees. Basically, the longer the time the water is in the radiator, the more heat it will transfer to the air around it. Providing the vents are free of dust, drying wellies etc etc. of course.

That's a theoretical start, but the trouble is that both the heating and house are dynamic when you take into account thermostatic valves, the house thermostat, where people are and what equipment is running in the house. So a beautifully static balanced system may put heat in the wrong place. It also depends if you want a heating system that warms the whole house evenly or the rooms you use when you return home. If you have thermostatic valves, balancing only really applies as the system comes up to temperature as the thermostatic valves will start kicking in. So my theory of balancing is to start off with a balanced system but then bias it by opening up the valves on radiators on rooms you want to heat quickest, this will reduce heating elsewhere but as the thermostatic valves kick in, the balance will redistribute to the other rooms. That allows you to switch on the heating later as you are not evenly warming the whole house. Remember, very few heating systems are properly balanced to start with and plumbers will sling in a radiator they guess will work, so theoretical temperature drops will lead to some rooms being overheated compared with others. Another problem, if you economise and turn off heating in a room, adjoining rooms are affected as the wall between effectively becomes an outside wall, without insulation so the radiator needs to put out more heat! Then bear in mind a big TV and sound system and couple of people watching TV will apply a lot of heat to a room, so the temperature of an empty room you want as you walk into, is not the same as the heat you want when the room is used. Did I mention the effect of opening and closing curtains? You are probably getting the idea now. Then the nightmare is what happens with a house thermostat which if the room it is in gets to temperature will cut off the rest of the house. If that is in a room with a thermostatic valve, how does that work? (Quick answer - it doesn't!). Oh, what happens to the balance when it gets cold and you turn up the water temperature of the boiler to heat the house? So in the end, setting up a system takes time. Think about how you use the house, how your system will change as things change. Don't be afraid to tweak a radiator down that heats a room too much and too quickly and use thermostatic valves as part of the balancing equation. It takes weeks to tune a system as every change interacts with the whole system and you need to learn how the system is applying heat in the real world.

Thermostatic valves and heads are mandatory in all apartment buildings for like 15 years here in Czech Republic, they probably know why they made this law. In the past, some people were overheating in small rooms where it gets warm fast so there was not enough hot water in radiators where it is really needed, thermo valves solved all these problems, nobody is accidentaly heating little room to 30°C like before. We had that theory in school about balancing with classic valves, but it works well only in laboratory, not in real buildings, even with all balancing done by second valve or other stuff, you still should always have thermostatic heads everywhere, it's ridiculous to not having them, I don't understand to people who don't have them, it changes everything.

Great tips, but probably need to ensure there's no air in the system by bleeding first. I usually just put my hand on the panels to see if they are all giving same amount of heat output, then do bleeding on any that are of a low heat output or warm at the bottom but cooler towards the top. The other tip, if TRVs are fitted (which hopefully they are), is to adjust settings correctly according to heat demand required. Bedrooms usually should be cooler to aid restful sleep. When not in use in the daytime, the TRV can be turned down, unless automatically controlled by a programmer.

Yes, but you have to be careful if you have a combi boiler and bleeding the radiators, it affects the boilers pressure and it may need adjustment after bleeding.

I just balanced my system based on the size of the radiator. For the smallest radiators (below 500 watts) I set the lock shield open by a quarter turn, the 800 watt radiator got a half turn, and anything larger (up to 2 kW) was left fully open. My aim was to force the largest radiators to get the lion's share of the water flow. What do you think of that approach? Seems to work OK on a short heating run, but being August I can't fully test it out. NOTE - my system has each radiator fed by 10 mm microbore from manifolds, which I believe makes it self balancing to some extent.

Great video. Straight to the point. Not time wasting. I like that.

What if the order of radiators can't be determined exactly due to unusual layout (extensions)? Does the order matter too much? Is there a good general/"rough" lockshield starting place before adjusting using the thermometer (e.g half turn for small radiators, full for large?). Also, do smart TRVs need to be temporally fully removed for the adjusting as they can't be "fully opened" easily like a manual? Pp

You can determine the order by opening up all valves fully and turning the heating up. They will get warm in order.

A suggestion, most folk like it warmer downstairs than in the bedrooms. Set the downstairs radiators to be fully on, and the upstairs bedrooms off. The bathroom radiator is often the fail-safe, that is permanently on to stop the system going bang. Set the thermostat, whether upstairs, as is mine, or downstairs in the living area to desired temperature. Eg. Mine at top of stairs is set to 18°C. Downstairs yours might be say 20°C. Heat from downstairs rises through the house and thus isn't actually being wasted. Obviously having the house walls insulated is first priority 😁

Note to anyone reading the original post. This is poor advice. Boilers are normally sized to suit the whole house size and all radiators. By turning off half the rads, the boiler will see hotter return flow and is less likely to condense (operate at max efficiency). You're also using half your rads to heat your whole house (unless you close off the upstairs, but the original poster isn't doing this as his room stat is upstairs!). I could go on and on.

To save money I’ve turned off all radiators except the bathroom upstairs, then just a small room on down stairs. I’ve completely forgot about the thermostat and even shut off the radiator that’s near it. I just turn the heating off when the small room downstairs feels warm enough.

Awful suggestion. You would be far better off turning the flow temperature of your boiler right down and opening all rads fully. Asking the downstairs radiators to do the works of the upstairs radiators you have already paid for is lunacy and is costing you money not saving it.

Be gentle with the spanner on the lock shield valve or you will rip the top off as I did.

Ouch

A different, and potentially better but more time consuming way, is to have room thermometers start with everything open and see which rooms are heating up fastest, then close the lock shields a little until they heat at about the same rate. If you can, turn your boiler flow down to where the house is then just comfortably warm - then you have an efficient system!

just install thermostatic valves and heads and let it be, hot water will always get where it's needed because you are not overheating, in smaller rooms, it's almost closed most of the time with thermo valve

Thankyou! This is something i have known needs doing for a while but never been confident enough to have a go. I have watched loads of other videos but nobody has explained it as clearly and as simple as you. I gave it a go this morning ready for winter (already snow on the ground) and its worked a treat! Thanks again, will defo be watching more of your videos 👍

Thanks you really explain things so well
