During use all should be fully on, the slot or lever in line with the direction of pipe.
Hot water doesn't need one because shuting cold water also shuts it off.
(water not getting very hot although radiators with stats working ok, temp and water set ok) This isn't clear to understand what you are saying. Which water domestic hot water from the tap or water in pipes serving radiators?
Most room stats click, but if heating is coming on at all it is functioning (if it is in circuit at all, it may be an artefact from a previous system, the no volts interuptor connection in the combi may just as easily be jumped. With no knowledge of the history some elemntary tracing is required.
