Just had a new Vaillant ecoFIT pure 418 boiler installed today.
3 radiators upstairs and 2 downstairs.
When the heating is on, the upstairs radiators are red hot and the ones downstairs are cold.
If I turn off the ones upstairs, the ones downstairs come on. I bled the downstairs ones just in case.
I'd like to understand what the issue could be when I chase up the boiler company tomorrow and would appreciate some advice please.
By the way, would I expect the company to fill any holes? At present I have an 8 inch by 1.5 inch hole through the wall into the cavity above the boiler?
