The TRV4 White is 'Class I' rated for efficiency by the European valve manufacturers association making it one of the most energy efficient TRVs available. Select fromcompression connections 15mm, 10mm or 8mm, or push-fit connection to plastic and copper pipe. I just went to fiddle with the one in the bedroom which broke recently (as I want to turn the heat down) and tried to turn the spindle. Britain's best selling range of thermostatic radiator valves set the standards for design, performance and quality, including TRV4 lockshield and pushfit packs to suit most domestic and commercial heating systems. If it does stick down and tapping doesn't work, try gripping the end of the pin with a pair of pliers and work it up and down a few times.

The TRV4 White is 'A' rated for efficiency by the European valve manufacturers association making it one of the most energy efficient TRVs available. Insert the black part of the peg into the main part of the unit - there are edges cut off the circle to help guide it in. The stylish matt anthracite finish offers a smooth wipe-clean surface that blends perfectly with anthracite radiators, and the polished chrome accessories provide a premium finish. I have tried the special balancing key and although this restricts flow, once the valve shuts off it doesn’t kick in again.

Thanks for the comments, I didn't realise that it could just be screwed off from the metal part, I thought I the screw was in the plastic part. The TRV4 Whiterange includesangled and straight valvesas well as lockshield and pushfit packs to suit most domestic and commercial heating systems.

The TRV4 Classic is Class 1 rated for efficiency by the European valve manufacturers associationmaking it one of the most energy efficient TRVs available. I have a Tower unit in my hand warming it up, so just passing set to 20°C suspect hand will heat to 30°C but more interested in time, and it took 2 minutes to close, and with just 1°C difference it would clearly take much longer, so within 5 minutes a radiator can go from cold to full heat, unless you use lock shield valve to slow it down, really want it to take around 10 minutes to give TRV chance to close. g. 21* down to 18*) the valves never allow anymore heat into the radiators, even though the room is cool (confirmed via thermometer). I had the same problem, what I did was compare target to current once the system has been running for some time, if target is below current then close the lock shield a little, and if target is above current then open the lock shield a little. This only lasted a few minutes before separating again so next I added super glue to the inside of the top cap, you must unscrew the black inner plastic fully before putting the cap on with max showing, and again thump them together.As you can see in the pictures I've attached, the Drayton TRV4 valve on the radiator in my bedroom has snapped off and there are bits of plastic left inside. It depends on a number of factors including the boiler type as a condensing boiler works best with a bigger difference. The liquid sensorprovides optimum sensitivity for fast reaction to temperature changes, ensuring that heating requirements are adjusted according to circumstances quickly and effectively.

I haven’t spoken to Drayton Technical yet as previous experience with ‘technical departments’ has rarely been truly helpful. of them have been broken for a couple of years but are in rooms where I don't need to adjust the temperature. C where the more expensive heads have twin sensors one for air and one for water so auto compensate. I wasn't very calm or polite and had to apologise to him afterwards, just a case of very bad timing I said!Britain’s best-loved TRV4 range now includes the Anthracite model to complement the growing popularity of anthracite radiators. Only when they are manually turned up (4-max) does the radiator heat up, but then they shut off and never kick back in even though room needs more heat. I also remembered I dislike them because the body only allows the pipe and 15mm tail to go into it a very short distance, which means no adjustment possible to suit pipes and not compatible with straight swaps with other brands bodies to original nuts and olives. C and the two TRV heads show 19°C and 20°C with target at 19°C since the TRV has 1°C increments that's about as close as one can get. If you've got a Marcus easy-access savings account or cash ISA, you can easily boost your interest rate to 4.

In any case, balancing all radiators to the same temperature differential assumes that each radiator exactly meets the heat loss requirement of the room - very unlikely. I needed to isolate it and drain it partially when the head came apart just like that when I accidently bumped it whilst I had the bushing off the top side of the radiator. The new TRV head will have the chrome screw-down fixing ring on it - turn the head up to 'max', position it so's the number is facing out (so's it can be read.
