Fit TRV to this radiator?

[garmcqui]

Hi all,

Looking to fit a 15mm TRV and lockshield to this radiatior. I'm not at the property at present, so only have this photo to go off, but it looks like 10mm rad pipe to me?



Is there a chrome reducer I can use? Can only find copper on Screwfix/Toolstation.

Thanks!

I was thinking of using this?

much better and easier to just get one of these

if you want to change the lockshield you will need a 15mm x 10mm drain down lockshield, no reason why you cant just leave the existing one

Where is the radiator located? There could be a reason for there not being a TRV.

Is it in the same area/room as the ambient thermostat? If so, it shouldn't have a TRV.

In the process of fitting an Evohome system, so need TRV valve bodies on all radiators.

Thanks bud, did look at those but I already have the TRV’s (albeit they are 15mm). Plus, I believe many of the 10mm TRV’s are just 15mm ones with inserts similar to those I posted above, no?

not all will accept the reducing insert, some do, it is all to do with the 15mm nut on the inlet, if you do use a reducer as you tighten it you will feel a snap as if you have broken something, this is how they work then you go on to tighten it up, try just hand tight before trying to fit the trv put the insert in and if the nut goes on to the thread with the reducer in it should be ok , as I said some do some dont
