Not all boilers have flow switches, Worcesters don't they rely on differential between flow and return, a valve is still a valve with or without handleOverheat / flow switch if your that bothered remove the handles

no because the filter only blocks one of the pipes to the exspansion pipe the other is still left open, and I have seen some really stupid tenants!Overheat
So that means every heat only boiler with a filter and external pump is at fault / problem
Remove the handles then you require tools to turn off and you should know better

Feed/expansion pipe/tank? Having looked at the layout of these (not really looked since college days 17 years ago ), I’m possibly understanding the problem.If the valves are shut and the boiler is fired up where does the expansion go?
