Missing TRV heads

[600rob]

The house i moved into a while ago has got several radiators where the trv heads are missing so i can control several of the rads

Is it possible to get replacement heads or an i best off just fitting new trvs?

By the way there are 3 different types of TRV around the house.... the only ones i can identify are draytons

Is it possible to get replacement heads

Yes. Take pics of the valves with missing heads and post them on here for us to identify them

I think 1 is a Danfoss
2/3 are terrier I recon

 

[Dan Robinson]

1 is a Honeywell VT valve

I thought that was one of those Danfoss where u set the flow direction.
Although I was suspicious of the "H"

Looking again the others could be the older Drayton ones that Bg used
