Im quoting to replace a boiler (oil) and its currently got a twin head pump arrangement which seems to work ok. Shall I leave as is, or should I replace with Y plan (or even S plan I guess..).

ive always found 2 port valves more reliable than 3 ports

Ray, is that return rate just the warranty period of the valve? If so what is the warranty length?
Do you have any mean time before failure info for honeywell/ drayton valves or other brand stuff?Yes, its just the "in-warranty" which I believe is a year on both plus 6 months shelf life time (until we introduced our minimum 2 yr warranty but that was too recent to affect this).
In that respect it doesn't help to tell you if one manufacturer has a 5 year mean time before failure and the other has 25 years.
