Hi just come back from my Mums. She has a vaillant turbomax 24 And quite a few of her rads are warm at bottom cold at top. I have tried bleeding them but nothing comes out.
The gauge on boiler is on zero, but boiler is working ok hot water and heating, I was told some time ago that boilers wont work when on zero. I was scared to top up boiler by filler loop as it is working.
Could anyone please give me the reasons and what I could do when i go back tomorrow especially if topping up don't work Thankyou
