Hi All, looking for a 22mm 3 port motorised valve at Screwfix and Toolstation and a bit bemused by the choice. Was intending to go for a Honeywell but its nigh on £100 and a Horstmann is £43. There's also offerings from Danfoss, Siemens, Corgi and Sunvic.
Posibly not. I have to admit that my post is based on my posibly out of date recollection that the Honeywell isa 3 port valve with mid position and that it remains in the 'last' position when demmand is satisfied.
My assumption is that the other 3 posrt valves listed work in the same way?
Ok thanks, so limiting my choice to 5 wire, does anyone have any thoughts on the other manufactures, ie not Honeywell? I like Honeywell but if I can save £50 on another that will do the job just as well I will.

Honeywell I imagine account for 9 out of 10 valves fitted in domestic installations and for this reason I usually replace them on a like for like basis. The Honeywell valves unlike others are metal cased which makes them more robust possibly, but I wouldn't say they are superior in any other way.
I always offer a cheaper valve to customers and some choose this option. Sometimes the customer is on a budget, other times it is because the fitting of a new boiler in the near future will make the new valve redundant so lifespan is not a particular issue.
If we go the route of a cheaper valve then I just buy whatever model the merchant has on offer.
