Hi,
Is it OK to replace a Honeywell three port valve with one from another manufacturer, say, Danfoss?
Danfoss make three port valves in a paddle type and a shoe type, what is the difference and is one preferable to the other? I believe that the Honeywell is a paddle type.
Finally, I was searching uk.diy from google for references (which I have just failed to find again) to descaling boilers and I found a couple of posts that suggested that conventional boilers don't really scale up, why is this?
Thanks, BraileTrail
