    M28 to M30 TRV adaptor for a modern thread on older rads (UK)
  

*by E***D on Reviewed in the United Kingdom on 24 February 2020*

I bought some Eqiva digital radiator valve thermostats at a good price only to find that our radiator thermostat valve screw threads are the older 28mm thread rather than the more modern 30mm thread required and thus I needed an adaptor in order to fit a modern thermostat. All these these type of adaptors are a daft price for what they are (even crude moulded plastic ones) and ended up costing more than the digital TRV I needed to adapt (beware a bargain bought in ignorance) but I took a chance on this & after seeing a German reviewer who purchased one for exactly the same requirement.This is one that Amazon UK sources from Germany (hence the majority of reviews in German). It is of a very solid, weighty, all metal construction and the pin is long enough for the digital thermostat to open and close the radiator valve as needed(no penny needed to bridge the gap as some have needed on rival products) so despite my bargain thermostat purchase needing this additional outlay (best laid plans etc) I can recommend this as the quickest way to upgrade your 28mm TRV screw threads to 30mm screw threads outside of just upgrading your entire radiator.
