Calling for hot water only, rads get warm
Emersion heater is on .
Flow on port b appeared hotter than primary flow.
240 volts on white wire, 0 volts on feed to it from controls when isolated.
So is this just valve stuck In mid position, and is hot water cylinder acting like a thermal store.?
Anyway, three way valve now changed and am testing.
Poorly installed job really.
