Can I replace this with a Smart TRV?

[Husk24]

Hi guys

I have replaced some of my Drayton TRV’s with the smart Tado TRV’s. However I have this installed in the kitchen radiator, the others I just basically unscrewed and screwed the smarts ones, but this one looks different to the chrome Drayton one (see pix)

My question is can this be replaced as easily as unscrewing and screwing the Tado with one the correct connector or will this require some plumbing?

Thanks

I don't recognise it but unscrew the head and see if it's like anything listed below...

So its ok to unscrew it? I was afraid incase radiator starts leaking water from there? clearly I don’t have the foggiest how radiators work but ok with replacing the Drayton TRVs

TRV's are principally the same so the head can be dismounted just like the Drayton TRV's, see the vertically knurled band just underneath the TRV head? Give that a turn in the right direction.

Took it off and this is what it is. So looks like it should be fine to replace it with a smart trv

Picture makes it look to be leaking.

Yeah I noticed that, wonder whether it was because I unscrewed it ? Can I tighten it?

You could try nipping it up but it doesn't look like a permanent leak to me, the gland might've let a little by when you permanently removed the head. Tie a coloured tissue around the base of the TRV and check it on it on a regular basis.
