2 Port 22mm or 28mm Motorised Zone Valve Head Can Replace Honeywell V4043H1056 V4043H1106 V4043C1156 V4043H1007
 V4043H1080

It works and it is cheaper than the original part.

I have a dual zone heating set up and the downstairs valve head stopped working which meant heating wasn’t coming on downstairs. Got my local gas safe engineer to replace it for me. Took him 20 mins and it’s been working perfectly since (been about a week so far).So glad this was only £25 on Amazon. It costs much more in other places like B&Q and Screwfix.

This seems OK and if still working in a week or so, I may well order another as a spare. It fitted on the pipe body part readily enough, the only difficulty experienced was refitting the cover to it, which took a few minutes to get lined up and pushed home without trapping wires (wrapped around motor body) and to engage the correct parts at each end. This MUST be done with power off (just in case) as (unlike the motor body I removed) this one has no separate earth bond wire to the cover. Deducted a star for these two points.

Arrived quickly, easily fitted

Bought this to replace a Honeywell one which packed up, thinking this was actually a Honeywell one because the advert states, Brand- Honeywell! To be clear, it's not made by Honeywell but it is an exact copy and a direct replacement, marketed by a firm in Manchester (but undoubtedly made in China) with the same coloured and number of, wires, so replacement is quite straightforward, following the very simple instructions included and working logically. I also watched a few YouTube videos, whilst waiting for it to arrive, just to understand how they work.As it was new territory to me, a friend installed it whilst I watched but I would confidently do it myself next time. Under Prime, it arrived the following day. Having extracted the old one we tested the motor and it was the problem, it was as dead as a dodo, so I could have saved a few quid by just replacing that. They are about a tenner but this whole unit was only £26, so I won't lose any sleep about it. Genuine Honeywell ones are about twice the price and whether this brand lasts as long, only time will tell, but so far, so good.

Bought this to replace an old Honeywell actuator. Wired up like for like, as instructed, and worked fine for 3 days until the micro switch failed and we woke up to no hot water.Buy cheap, buy twice….

This was the second of these units I tried. Out of the box neither of them worked. The actuator arm does not contact the microswitch when in the manual open position. Hence the first was returned. When the second unit had the same problem I bent the end of the actuator arm so that it hits the switch and it's now installed and working. Even although this is about the cheapest one of these on Amazon it feels just as well made as the genuine Honeywell one, which had failed anyway.

I swapped out (yet another!) dead 'Honeybad' valve with no problems whatsoever. Functions well. Looks like it will last as well as, if not longer, than the original.It is physically and electrically compatible with the 'Honeybad' product (the cheap gear mechanism is what usually fails in those - terrible design IMO).Note: get a qualified electrician to do the job!Buy hey... tips:**** Note: Do this at your own risk - get a qualified Electrician to install, check etc. !!!!SAFETY: ALL POWER OFF FIRST!!!Swap out the old for new, matching colour coding of wires. Take a picture first, to show original wiring!If the connection point has poor access, or is just crammed with other wiring, consider adding a 'flying lead' box to ease changing over valves:- The lead on old, inoperative valve was cut near the valve, stripped, and rewired into a...- Honeyw*ll terminal box (2 x 6way terminal blocks - so enough for 2nd valve when it fails!)- The new valve was then wired into the terminal box, like-wire to like-wire.This leaves the original, more complex wiring box, untouched. This is especially advisable if you have several zone values in addition to a hotwater valve. On a previous failure, the original terminals were crammed on my system and it was very difficult to remove individual wires and then try and insert new ones, whilst keeping other wires in place!**** Reminder: Do this at your own risk - get a qualified Electrician to install, check etc. !!!! :)Other tips:I found no problems - but do DOUBLE-check the connections - including INSIDE the valve - especially the Earth!!Don't cover the valves - they get hot as it is.Use minimum force to manually operate the valves - that mechanism is the weakest part of the design (both old and new)!Enjoy!
