"Bought 2 pairs of these TRV's to complement some large vertical rads, the valves fit in either plain, a pleasure to work with and look as good as you would expect. Nice chrome finish and coloured temperature range."
"The product is of superb quality and I cannot fault it.
The service I received from Screwfix was second to none. The ordering was easy, delivery was prompt and Parcelforce who delivered it were polite and notified me by text that delivery would be during the next hour."
"These are the best - I have now used three of these the first two (12 months use and going strong) the looks and performance are excellent. Good looks. Excellent quality. Just fitted the third today. They look the business with our designer radiators."
"This is a good quality chrome liquid sensor. It was easy to install and looks good. Easy to use with smooth rotation. My only concern is that the barrel hole of the valve is much smaller than the 15mm pipe so can get clogged easily but time will tell. I suspect all thermostatic valve have small holes. Functionality wise it does what its suppose to."
"The lockshield is a duplicate valve without a head, good if you decide to change ends at a later date but NO advise on how to set up for balancing!
Having arrived to do the job you find you have to "request the data sheet D34 from Drayton" if you have internet access and download it you find they then want to sell you Pre-setting keys available in packs of two, part number 07 35 162. A search showed them at £9.34!
So ok you can figure it out and bodge the adjusting with pin nosed pliers but I can't be doing with manufacturers who think everybody knows their products inside out and wants to carry around special tools that they may not need for months by which time they have got lost."
"Valves bodies are blank off apart from a small hole. As both ends take the same body the flow rate is restricted so if the radiators in question are not given priority the flow is practically non existent. Drayton's previous TRV which I've had 12 for approx 15 years have a 15mm opening in the lockshield and the TRV valve itself had only the valve with no added restriction of a small 6 mm hole (approx) drilled in the bodyopening. Money WASTED would not recommend and Drayton technical department were as helpful as chocalate fireguard. Balancing the flow was impossible."
