We had the boiler fitted in 2015, last winter it had an issue that when the hot water was turned on the pressure in the heating system started to rise and would go above 2 bar if it wasn't switched off straight away, the same issue happens is the heating is turned on. The problem righted it self after a couple of hours turning the tap on and off. The issue has now returned again, can anyone offer any advice as what this could be????
