hi overflow in tank is overflowing, not from f&e tank, system comprises of heat only boiler, unvented cylinder, which i have just replaced yesterday because of constantly overflowing tanks. (assumed coil had split)
Water had been going up expansion into cws tank making the water luke warm ball valve has also been recently changed although this is irrelavant as the water is luke warm so that can't be the problem.
There is a pump fitted to hot water directly from cylinder supplying whole house with hot water cold feed is mains
mixer taps to all outlets and thermostatic mixer shower above bath. can't see that these are causing problem as all new and pressure is fairly equall, and that i installed pump and bathroom suite approx 1 year ago and problems only just started.
f&E tank is slightly lower than cws tank but can't alter or put expansions higher because of pitch of roof, and again it's been like this all the time so why would it be causing a problem now?
HELP im all out of options.
