Hi I tried to find the Heatline valve head but could not find it in the internet and ordered sth similar but did not fit and was smaller. Do you know what is compatible? Thanks
Can't tell the size with the tape like that but it may be an old M26, measure the diameter of the threaded section side to side, that'll be the size you'll need.
You may not be able to get the size you need any more but will probably be able to get an adapter. May be cheaper just to replace the whole TRV.
