Evo he boiler leak

[jamesp24]

Hello peeps after abit of advice about a possible boiler problem.

The boiler is an evo he ??.i think there might be a leak somewhere in the system but im not sure as the boiler usually reads 1.2or so bar but when the central heating is on it drops to around 0.5. it needs to be re filled by around half bar every few months.. any help would be much appreciated.

Thanks

Also all the radiators are hot when the heating is on and the water pressure from the tap hot and cold seems ok.

Thanks.i had quick read over the expansion vessels ..my pressure is going down when the heating is turned as opposed to up : / ..

that drop over that time is not a problem ,it is most likely a seep from a joint,check around any joints on rad valves etc
