Radiator valve head replacement

[sam]

I'm very confused to the different types of valves and heads, please can someone help? The temperatue control for one radiator at home stopped working. The plastic head is faulty and won't twist open or closed anymore. I've take it off and the pin in the valve functions fine, and the radiatior is thankfully now on full blast! So it seems like I just need to order a replacement plastic head but I don't know where to start. Can I just get any old one? They seem to be different sizes? The one I've got says "Lifestyle" and on the side, "0906". All the numbers are Roman. I can't find the same type on the internet so I wonder can I just get any old one that looks the same? Will it fit and work properly? What do I need to look for? Thank you community!!

The other approach is to see if you have a matching head on another radiator, and take that to a good DIY store to look for a match. Do you know any friendly plumbers? (but please offer them beer tokens).

It looks like "lifestyle" is a Drayton brand - they seem to have changed the branding from "Drayton Lifestyle" to just "Drayton" at some point. It looks like this -

- may be the correct part. As it's only a tenner it might be worth a try anyway.

But if it's the older TRV3 then the thread size of current range is different and conversion heads are really stupid money @ £50+.

The gotcha may be the Roman numerals for the settings which may indicate Myson as a possible manufacturer. Probably a photo of the head is advisable to rule out some brands/heads.

If the OP has some DIY central heating skills then a complete new TRV may be cheaper than just buying a replacement head.

I wonder if the TRV has been forced beyond a limiting pin and removing this pin will allow it to be moved back.

However none of the

Hive has a good pictorial guide as to the different types of body:

(they will also send free adapters, even if you don't 'yet' own a Hive)

Wouldn't a free adapter only fit the hive?
