Replacement head for Myson TRV 2 WAY thermostatic radiator valve. Interchangeable with the standard Myson thermostatic head (which looks the same, but has red markings and a white bottom section).

Head only - no valve included.

Our video shows details of the head, including how to identify a faulty head and how to replace the head.

 


Faulty Myson TRV head compared to a good one

Myson TRV heads are normally very good and last for many years, though one failure that can occur is an internal fault that causes the centre pin to be permanently stuck in the out position. This failure results in the valve being shut off and a cold radiator. The picture above shows two heads, a faulty one on the left and a good one on the right.

TRV 2 Way valve heads made between 1997 and 2012 had a symbol like the greek letter PI. This head, with the EN215 keymark symbol is a direct replacement.

The metal lock ring has a M30 / 30mm x 1.5mm metric thread. Myson has used this thread for a long time, though very old (pre 1997) Myson valves used a smaller 28mm x 1.5mm thread.

The picture below shows what the very old thermostatic heads with m28 threads looked like. If you need to replace one of these you'll have to buy a new head and an adaptor (available in our store).

Ordered 2 for my radiators. I know nothing about DIY and easy as the installation is I was a little apprehensive. That is until I watched the brilliant video instructions - clear and gave me all the confidence I needed to do it myself! Will be getting another shortly and definitely recommend. Quick and efficient service. Regular email updates on order. Just 1st class service really. Parts with me in 2 days and that’s with Christmas post. Thank you (28 Dec 2017, 22:21)

Absolutely first class service, ordered 4 units late Monday evening, auto accept directly. Tuesday by 09.30 confirmation order complete, in my hands by Royal Mail Wednesday mid day, and more competetive than the Am site. Well done will certainly recommend you to friends. The information video was first class also, no doubting faulty units after watching. Well done to everyone concerned. Thank you ( 8 Nov 2017, 15:45)

I found the website page about the valve very informative and helpful. The video on the page was a useful addition. This was able to convince me that this was the replacement valve that I required. Delivery was quick and part fitted successfully. ( 6 Oct 2017, 16:27)

Myson 2 way replacement head

I recently purchased three replacement heads as another one of mine had broken, after 18 years and the new ones are direct and identical replacements. The other 2 are spares. The cost and post seemed very competitive and it was nice to be thanked for placing the order and to receive an e mail confirming the very quick despatch. They arrived the next day so 10/10 (16 Oct 2014, 19:54)
