TRV Radiator Valve position

[nuttabiker]

Hi

Might be a stoopid question but...

Does anyone know if I can fit a TRV to the top of the radiator rather than the bottom? If so I presume the outlet valve must go directly underneath...? Or should I just stick to my day job?

Cheers

There's no particular reason why not, but the TRV might be affected by the higher air temperature at the top of the rad, so might close earlier, which just means that you have to turn it up a bit.
Make sure you buy a bidirectional TRV (such as the Drayton TRV4), because the top rad connection is likely to be the 'return' pipe (i.e. to the boiler, not from it).

It is a TRV4 BUT I would have fitted it the wrong way round without your comments. Cheers Softus.

You're very welcome, but now you've confused me - how do you fit a TRV4 the wrong way around?

 

[nuttabiker]

I'd have fitted it on the input FROM the boiler rather than as you suggest the return TO the boiler.... Cheers

I'm even more confused now.

From your first question I took it that you didn't have a choice of fitting positions.

If you can fit the TRV4 on the bottom rad connection, then do that.

If you can't, then you can't, in which case make sure that, if the top connection is the return, that the TRV is bisexual (which it is, because all TRV4s are).

 

[nuttabiker]

Sorry for the confusion Softus - I'm pretty sure I do understand you correctly. The TRV needs to be fitted to the top 'cos I can't get to it otherwise.

The flow will be IN to the bottom of the radiator and return to the boiler from the the top through the TRV.

I've sexed the TRV and yes, it swings both ways

Thanks

It's all good.

From what you say, it sounds as if you radiator is connected in the TBOE (Top, Bottom, Opposite Ends) configuration instead of the more usual BBOE (Bottom, Bottom, Opposite Ends) configuration.

Pardon my ignorance but, from what I have read on this site and others, I undertood that with a TBOE the flow entered at the top and the return was from the bottom

 

[kirkgas]

i also thought top entry was for flow, not return, i have always found top entry TRV's to be troublesome, complaint usually that rad turns off too quick, because the latent heat rising from the rad affects the TRV

Well, nuttabiker, now you know - you are required to repipe your radiator.

What a D*ick.

Fair play - you were wrong but are not man enough to say it.

I thank you for pointing it out,

No need to thank me, think of me as a Missionary educating the Ignorant.

AH, Bliss! Remind me to dredge up your simpering apology regularly everytime you have an argument, you seem to take great pride in doing this.

Let`s see how you enjoy it.

There was no argument here. It was a small mistake that didn't affect any any other aspect of my post.

I made an error, which was pointed out, and I acknowledged it and apologised. It isn't the first time, and it won't be the last. Gloat all you like, it doesn't change anything.
