Hi, Jan here from South Coast Boilers in Newhaven. scboilers.co.uk Yes - there is a leak somewhere. It could be under the floor, but before you start moving furniture and lifting up floorboards; Check the pressure relief valve is not "letting by". Or in simple terms, go outside and check if there is a pipe dripping. If so, you may need a new pr valve or, your expansion vessel may need inspection/recharging/replacing. If you can't see water coming out, I would then begin to locate the leak by bleeding the radiators. The radiator with the most air inside - the leak will be nearer to that.

Hi Pat If the boiler comes on without demand then that means there's something wrong with the controls. If the pressure goes to 3 bars then after a while goes to zero ,then there's a problem with the boiler components ,it's unlikely a leak in the system pipes . Regards
