Have look out side wall boiler pressure relief pipe is outside if notice any sign of water if its than boiler pressure valve faulty,just follow the valve pipe if it's hot than it's faulty ,if Ok than you have to look out for possible leak in heating system ,if under the floor than you. Have to isolate by mean of gate valve flow and return ,but first one more likely
