"Purchased this after noticing that our radiators were getting hot with just hot water set on the programmer. The 3 way valve seemed to be working ok visually but must be playing up so it was certainly easier to try a new motor than changing a valve.The motor was changed in about 20 minutes, made easier by having spade connectors fitted already, tested and it worked and problem solved. So I would definitely recommend trying a new motor before the valve. Have given 4 stars for reliability as its only been fitted for a week, otherwise, very pleased with this solution. Thank you."
"After reading reviews I ordered this motor to replace a original honeywell motor from a 3 position valve. The original had lasted for 25 years. It was a identical unit and fitted in minutes. Supplied with crimps to join the wires. I am a electrician so had crimpers to make a good connection. Cant say about reliability yet but works perfectly."
"Have a Horstmann F222 two way zone valve that was playing up. Picked one of these up after reading other reviews. Easy to change (2 screws) and used soldering iron to remove 2 wires from tiny PCB and re-soldered new wires in, works a treat.
The motor is made by Synchron (USA), who, I think, are the original manufacturer of these motors. Its a shame that Horstmann chose to fit inferior motors that only last a year or two.."
"This is the second replacement motor bought from Screwfix to keep a now 22yr old Honeywell valve running. The previous one has lasted nearly 10 years, and fitting is so simple, a 5 min job. Click and collect from the local depot was effortless, thank you!"
"A good brand which should give reasonable lifespan. Very useful as it save having to replace whole zone valve. Check cogwheel drive though as if you have a Siemens (Landis and Staefa) RMH valve you will need to change over the brass drivewheel as the original has a longer reach. Also before you change you may find that the electrical connections need to be revamped for the RMH valve."
"Replaced the motor in a Horstmann F322 which had been installed for only a relatively short period of time. Ideal replacement, and fittings provided to connect wires. Great relief not having to replace whole valve!"
"When the motorised valve packed up on my Horstmann F322 three port valve, I traced the problem and found to my dismay that the valves are not that reliable ,with the motors lasting around 18 months, I thought that I would have to drain down and fit a whole new unit...but wait whats this a replacement motor that might fit.... and it does, it took me all of 15 mins to exchange the motor and the kit even includes crimp connectors to connect to the existing wires....perfect. Fantastic value item, I have scored it 5 stars for reliability even though its only been fitted for a couple of days, even if it fails next month its still a cheap no messing fix."
"My Honeywell heating valve was playing up, so after getting a quote for call out and possible parts all amounting to around 100 pounds plus, I decided to do it myself. The motor was a straight swap and rewire, all easy to do and done in less than 15 min. System back up and running for the price of this motor. I would recommend trying this before replacing more expensive parts."
"A lot less hassle than replacing a complete valve I'm a spark and not a ch installer but I found replacing the motor easy enough the wiring is self explanatory really. all in all a simple procedure. Gave reliability 4 as only installed 2 weeks ago."
