All the guides online are great only in theory imo. There's too many variables that effect systems to just do the rads in order. My plan is always to shut down the upstairs rads at the lockshield as much as possible just - before they close and open downstairs fully. The heat will naturally try to go upstairs so rarely is there an issue getting the upstairs rads hot. then if there's a big difference between any close the ones that are too hot down a bit then open the colder ones a bit and keep doing this over time until its as even as you can get. The method of closing the rads in order I find only works in theory. Systems can be all over the place with blockages and rad sizes that are so different they effect the flow. 17 rads could take hours to get perfect.
The basic problem you have is believing your opinion is fact and then set out on a mission to convince people you are right. The principle demonstrated in this video is absolutely correct and as said in the video is laborious. That does not mean it is impossible nor does it mean that it cannot be done with a bit of effort. But just because it is difficult does not mean it is better to listen to your opinion. We know it it is time consuming (and exactly why most plumbers cannot be arsed to do it) but that does not mean it should not be done.
@@normanboyes4983 I'm not saying it shouldn't be done. You said those words. I'm saying doing it won't even necessarily be correct anyway. Sometimes you will get rads further down the chain that will get far hotter than those closer. Of course using the temp probes is best in any scenario. But imo it's not the case a lot of the time that it will be closest is hottest. Knowing the order isn't alway possible either. Take a chill pill. For people doing it DIY as well stuff like shutting upstairs can save a lot of problems.
We have 17 radiators. What you suggest sounds an absolute nightmare. What about the bypass valve (Honeywell DU144A1001 Straight Automatic Bypass Valve) and the settings on my Grundfos pump (Type UPS2 15-50/60 which has settings I,II,III and Automatic (I have it set to Automatic)) I have spoken to the manufacturer but find that they have little understanding of the system. My question is how do these additional components need to be set. I get the impression that my plumber does not understand it either. I have tried IR thermometers but they are not plain sailing.

Ha ha that made me chuckle :-) My wife sits there cold, I say "shall I put the heating on dear," No! comes the reply. I sometimes wonder if I should say "Well stop complaining then" I know my place 🙂
Thanks al and Jan jolly useful video as usual 🎉
Thank you! 😃
An infrared thermometer costs about £20 and reads the temperature quickly and fairly accurately
True but they measure emissivity not temperature.
Thanks guys.

Yes depends how thorough you want to be.

Leave the pump on auto, the bypass will not effect the temp settings. All you need is as close to the 12 degree difference that you can get.

so the temp should be 12c higher on the inlet than the outlet?
That is right.
None of my rads heat up Al, the Nagging machine won't let me put the heating on!!🥶
Ha ha think of the money you are saving.

Man leaving his house tells wife to put her coat on. Surprised, she asks if he is taking her with him, "no dear, turning off the heat"!
