"Replacing the TRV's at home and this one was part of a bathroom refurbishment. The criteria for the selection was it had to be Danfoss - have used Danfoss TRV's before at home and commercially, never had any quality issues. It also need to be, in this instance, a chrome finish to match the taps and towel rail, valves, etc. The picture of the product look good but seeing the actual product this looks a really smart product. I bought the combi pack so this includes the lockshield valve as well. Includes fittings for smaller pipe connections up to 15mm so vary adaptable. This TRV has a flow direction selectable feature which can be used without disconnecting the TRV should there be an issue with noise - water hammer, not an issue in my case. Instructions provided were good and concise, packaging OK but a better protection to the chrome finish could have been better afforded for the price of the product. Listing in the Screwfix Catalogue could have identified if a combi pack or if white or chrome - combi pack & chrome / white can be deduced by the price but I had to get both packs out at the counter to be sure. This is a premium product, easily to install by professional or competent diy'er alike. Recommended if a smart looking installation required."
"Very pleased with product. You can fit trv's on either flow or return to avoid curtains. No water hammer when they shut down together. No leaky glands on lockshields like my old ones. Chrome looks good and I hope will not show any long term heat damage like my old white ones"
"This was the best looking trv (in my opinion) and looks great mounted, the locksheild is also tidy and compact. I will definately fit more of these in my house. It was easy to fit, although the grub screw at the back is not that easy to do up, especially with the miniscule allen key supplied (ok for smurfs!). This trv had a slighltly higher max working temperature compared to the others that swung it for me as it was for a chilly hallway. The only downside is the markings are VERY feint and hard to see, so maybe not so good for older people, but in reality, you either turn it up or down! A stunning TRV but you do pay extra for it."
"I have bought a few of these TRV's after some of my old ones started to get noisy. I was particularly attracted to the revolving body that means that the valve is always positioned best for the water flow, unlike dual-flow valves that I have found start to 'hammer' after a few years. These TRV's are extremely well made, and make cheap valves look and feel like junk. I have only had one of these valves fail when it was mounted vertically downwards from a towel radiator in a bathroom and after a few months it started leaking brown gunge from the valve body. Danfoss informed me that these valves should never be mounted vertically downwards as they can fill up with condensation and perish the seals. The replacement TRV was fitted horizontally and has performed perfectly."
"Having expected these valves to be metal and discovering they were plastic was a little disappointing for the premium price paid, but now they are fitted, I am glad I didn't go for a cheaper looking product as they look fabulous. Hopefully they will perform well, with a reliable manufacturer like Danfoss, and for something that is on view all the time, especially on towel radiators, they look classy and contemporary."
"Trying to find a decent looking TRV and lockshield to purchase on the same day isn't easy. This, in my opinion, was the best looking one to go with the Oceanus anthracite radiator I had bought (had also looked in the typical DIY stores but found nothing better). I have a Drayton "chrome" TRV on the bathroom towel rail/radiator and I think the Danfoss doesn't feel as plasticy, though still not as high a quality finish as you would like. Chrome, chrome plated, chrome finish suggests a better quality than shiny looking plastic which is more the reality of these products. I puzzled over the (required) 8mm reducer as there were no fitting instructions regarding its use. Turns out you just put the reducer over the pipe and tighten up. The reducer then gets compressed round the pipe and separates into 2 parts acting as an olive and reducing bush. I only know this cos I trialled it on a spare section of pipe. Was then a pain to get off and fit to the rad flow pipe..... I have had no issues and obtained a water tight seal on the first fitting, so far so good. The valve selector is good and I have fitted the TRV to the return pipe as opposed to the old valve which was on the flow. Nice option to have. A bit more expensive than some of the other options available and for that I agree that a better finish should be expected."
"Yes you can get cheaper valves but I bought this one primarily because it looked good and matched the rest of the fittings in the room. My only moan is that the markings for the heat levels could have been a little bit darker as they are very faint (certainly they are not as dark as is shown in the picture).Instruction were clear and precise. Overall I'm well pleased with the purchase."
"had this product installed for 6 years I had to wind down both the TRV and the lockshield to isolate several RADs for some maintenance. Horrified to find on re-commissioning that the lockshields have leaked.
This has happened so far on 4 RADS
according to Danfoss this is because theres an internal O ring which corrodes over the years and cannot be replaced
the internet implies if you buy a lockshield with a 'glandnut', you stand a better chance of servicing it if something goes wrong
Whilst i'm not an expert, to me a lockshield is a fundamental part of RAD maintenance. it should be able to seal off the RAD then open it up again for many years. Afterall, if a TRV can be turned up and down and switch off and on without leaks why can't the lockshield be designed to do the same?"
"this valve is very expensive, very plastic looking was very disappointed for a danfoss product. need to make alteration to valve for flow setting. the setting indicators are almost invisible. would never use them again"
"Did not even fit it. It's going back. Looked good for the very discrete lockshield valve, but the chrome finish on all parts is garbage! Went for Comap Sphere manual valves instead for less than a third of the price, with a proper chrome finish and nicely rounded nuts and edges."
