Hi
My CH system is a Rayburn Heatranger with underfloor heating downstairs and conventional radiators upstairs.
I need to drain the upstairs system.
My questions is.
Are the 2 systems separate or connected ?, ie if I drain the upstairs system with the pressure drop in the underfloor heating system.
