Rated 5 out of 5 by reliable 3 port valve These are a good valve, they now have genuine "syncron" motors in them. A lot better than the previous Horstmann model which had cheap copy motors that failed quickly. Like all central heating parts(other brands of 3 ports included) they do not like systems full of sludge !! If they start passing after a short time and your system is full of sludge don`t blame the valve, blame your system!!!! 12 Nov 2014
Rated 5 out of 5 by mid position valve value for money valve and compact to be installed in some very small spaces.... 9 Jul 2014
Rated 1 out of 5 by Ditto Fenderer. This is really a review of Horsmann's poor quality and backward incompatible products strategy. Firstly - I've had an F223 for less than 15 months and the head circuit board has blown. Searched high & low for the receipt, can't find it so need to re-buy a head. Secondly - Can't buy just the head!!!!! have to buy the whole head & valve. Thirdly - can't even buy the whole thing and just bin the valve. As Fenderer (thank you mate) points out, the replacement product (Z223) head doesn't fit the F233 brass. So instead of a quick clip-on and wire-in I have to drain the system. Lastly, the only good bit. Because Fenderer clued me in, I don't have to re-buy Horsmann. 29 Mar 2014
Rated 1 out of 5 by WILL NOT FIT F322 VALVE BODY I bought this Z322 diverter as it was advertised as a direct replacement for the F322 enabling the control box to be swapped without changing the valve body. This is NOT possible. The valve body design is completely different and there is no detach button like on the previous model. You cannot fit the Z322 control box to a valve body F322. So now I have to drain the system down can fit the valve body with all the hassle that involves. Not at all impressed. 17 Nov 2013
