Boiler and room stat settings?
Comments

How individuals control there system is a matter for them and their individual taste
HOW a system actually works is entirely different
So is that statement about TRV's not factually incorrect? i.e. gently heat your home to the set temperature etc. if they are set to a lower setting.:doh: Blue text on this forum usually signifies hyperlinks, so click on them!..:wall:0 -

It is the context of the way the whole of the controls are set that is the determining factor, not just how individuals achieve what they want!
As a generalisation you will only get out what you allow in, and you wont get more out than is determined by the outputs that are set, or the maximum possible outputs of the system components
The argument here is about how those components work, and lockshields do not prevent the output of a radiator, they are designed to maintain the flow at a set rate, that flow, no matter how low it is restricted will eventually mean the radiator will reach and maintain the temperature of the system as determined by the boiler stat setting!
The only thing that determines output from the system components are "controls", controls stop, and start, output, be they stats or timers, a lockshield is not a control as it is a fixed setting, and a balancing aid to ensure equal delivery throughout the system
Lets give a simple example, if you have a tap dripping that tap water that drips will be at the temperature of the supply water, if that water gets hotter, then eventually that drip will also be as hot as the water that supplies it Signature removed0 -

Forget the lockshield argument. You mentioned "this forum and the people who run it" and the MSE article quoted is supposed to be about energy mythbusting but it contradicts what you posted earlier and surely this can only confuse those who read the article.
If a TRV is fitted then that will modulate the flow of water through the rad in accordance with the temperature setting that is desired for the room by adjusting the themostatic head, the water that flows through the rad will STILL be at the temperature as dictated by the boiler stat setting, WHEN the TRV modulates to OPEN, FACT:doh: Blue text on this forum usually signifies hyperlinks, so click on them!..:wall:0 -
Does that mean you agree or disagree?
DISAGREE;)BTW there is kernel of truth in the statement "if the rad are not balanced then the boiler cycles" Of course modulating gas boilers don't cycle
Umm so modulating isnt cycling then is it, and that is not correct either as when the system is fully satisfied the boiler will go off, and come on again when the system is not satisfied, the degree of cycling is what is important;) as the more it cycles then the less the system is fully satisfied, the quicker it is fully satisfied the less fuel it will use
but if you are taking about oil or old gas (on/off types) then an unbalanced system can result in most of the flow going through just a few rads instead of all of them. Then you have say a 10kW boiler driving 2kW of rads (rather than say 5-7kW of rads). The house struggles to get warm and the boiler can't dump all its heat so ends up cycling on/off.
Huh, what are you on about, do you not understand the way rads are piped in a continuous loop with the flow of each rad being returned to the return loop of the system, let alone about balancing :rotfl:
There are thousands of systems out there where the lockshields are fully opened on all rads, and equally as many where they are restricted to the minimum, they will all work, how efficiently is a different matter :rotfl:Signature removed0 -

:rotfl:Terribly sorry about that, but the fact is, in the real world not just this forum, that the whole issue is contentious with people, some of whom are extremely qualified, and more than I am, of equally opposing views
The simple fact is, it is confusing, and there are opposing views, like many things in life, and some more important than this, and the only way to prevent confusion is for those that are confused to try whatever option until they reach the one that satisfies them
personally i prefer the ones that work!
Unless of course you would like just to deal with robots or clones, dont think thats gonna happen :beer:
:mad: DAMN, where do these people get the idea that no one should disagree with them and what is written here is written in stone :mad:
Let me say this to all of you on this subject, that WHEN someone can prove the differences in opinions by setting up 2 Exact same properties, with exact same installation, with exact same parameters, but different setups according to opinion, and produce some definative results as proof of what is correct, THEN they can determine who is right, BUT to this point in time no one has done that, to my knowledge, so its your choice as to what you believe
THEN factor in the manufacturers who use substandard materials and components which shorten the life spans of appliances, and do a comparison of THEM over a life span, and THEN there may be a definitive answer of ECONOMY :eek:
Consider this also as to which is the best economy over a life time, an old appliance that gave little problems with component parts that would last 50 years, or a modern one that has a life span of probably 6 years with even less for its components, then I MAY consider some of your points, ONCE you are expert and lived long enough Signature removed0 -
turning your thermostatic radiator valves down will mean your radiators will not get as hot and will gently heat your home to the set temperature.
this is totally incorrect, trv's work on air temp around the head of the valve it has nothing what so ever to do with the temp of the rad or the water flowing into it, that is controlled by the boiler stat, for example if the trv head was blasted with cold air below the temp the valve was set at, then the valve would remain open but the rad would be at the temp set on the boiler statI'm only here while I wait for Corrie to start.
You get no BS from me & if I think you are wrong I WILL tell you.0 -

The simple fact is that the information published by MSE Guy in the energy myth busting article referred to is WRONG.
I informed the team of this error when the article was published last year but MSE journos obviously think that they know better and have not corrected the article.Guy Anker

I don't understand why you have posted all of that irrelevant waffle when you know exactly what I am referring to, perhaps you should be a politician, not a plumber!:doh: Blue text on this forum usually signifies hyperlinks, so click on them!..:wall:0 -

Your right it is wrong, like so many response here by people just the same who THINK they know it all What you call "waffle" just sometimes NEEDS to be said but i'm not just a "plumber" I have many strings to my bow learned and qualified as over many years
Its in respect of that, that there are too many people who have NOT had the experience, and the qualification standards are certainly not as substantial as they used to be either, that think they know it all BUT DON'T also
AS always recommended on here its buyer beware and if you really really don't know, try keeping your gobs shut before you cause damage or harm to someone, because THAT REALLY REALLY ISN'T HELPING ANYONE Signature removed0
