Not sure if I'm in the right section but does anyone know about gas CH boilers please? Mine is a Worcester Bosch, great thing but intermittently I have to top up this pressure? thing with a little tap. I did this the other day as the needle was basically on 0 and now when it's idle the pressure is as per the picture. I noticed though that when it was heating the house the needle is going up in to the red zone. I panicked and turned off the heating! Is this something to worry about or normal behaviour? TIA
