Review: Huge improvement on old and discoloured thermostatic valves - Had boiler replaced and installed a new Hive thermostat. Didn't want Hive TRV's but decided to upgrade to modernise the TRV's on the radiators which are more then 20 years old. Easy to remove the old ones using an allen key and very simple to fit. Much improved temperature control than the old ones and aesthetically much improved!
Review: Replacement radiator temp knob - After some years the plastic of the original thermostats was brittle and broke when pulled off to free up the stuck internal plunger rod...Rather than replacing with new £90 thermostats plus a drain down..Just replace the caps! making sure you get the right one!...

## Questions & Answers

**Q: Will this fit a 30 mm valve?**
A: Hi, I've measured the entry and it appears to be either suitable for a 22mm or 25mm thread but not 30mm. If you contact Danfoss technical sales support they should be able to provide you with part number for the valve head that would be suitable 
Regards Jim

**Q: Will this work in place of older Danfoss Rad sensors? I have one that has stopped working, the opening at the bottom is 22mm with an allen screw.**
A: Hi - I used this to replace a broken TRV of the same make and it worked perfectly.
