Rated 4 out of 5 by from 3port valve change Called out to a heating system were the heating was coming on with the hot water, suspected the 3port valve so picked one up from Screwfix and changed within minutes.Problem solved.

Rated 5 out of 5 by from Easy to fit and works OK One of the better motorised valves on the market. The rotating brass valve is not affected by additives to the water, unlike those with a rubber ball seem to be. Easy to wire. Plumbing side is easy even for DIY. One word of warning - some valves must have a different motor fitted as the manual/auto level location can vary - look at the labels carefully before fitting the actual motorised top - which is easy to replace if required.

Rated 2 out of 5 by from Wrong item in box Needed a Danfoss head in a hurry and Screwfix only place open Sunday that stocks it. Good service from screwfix with correctly labelled box. Wired up, only to find that the kit contained a 3 port valve body but a 2 port valve head. Took back no others in stock, so got full refund easily but a Sunday morning wasted. I am happy with screwfix but very unimpressed with Danfoss. Product ratings above are therefore irrelevant.

Rated 4 out of 5 by from very well made valve I replaced an identical leaking valve and dismantled the old one. I was amazed it was easily possible to restore the seal with a couple of new O rings, very unusual with modern manufacturing methods . It was a relatively expensive valve but I now have one in reserve so I rate that good value.

Rated 3 out of 5 by from Replacement valve This valve was on stock and ready for immediate pick up. The valve itself was purchased to replace a leaking valve and not for a new installation. The valve seats fail quite frequently, hence not very reliable.

Rated 5 out of 5 by from Good quality item Does what it says on the tin. Easy to fit, straight forward wiring diagrams, no issues and worked fine

Rated 4 out of 5 by from Replacement valve Usually the electrical head fails on these valves, this time however it was the mechanical divertor that had seized. Well packaged and used as a direct replacement no problems were encountered. Customer now has hot water and heating at the correct times! Obviously can't comment on reliability but the previous Danfoss lasted many years. When you consider what's been purchased I think all of these valves are expensive. However I have tried cheaper ones and they don't last.
