No - theres no way of telling really as nearly all my floors are either nearly new carpeted or I'v put wooden flooring down over the floor boards and I'm not gonna start ripping up flooring now - I'm trying to avoid that !.
I'm sure my systems a reversed return like nearly all central heating...
How do I go about installing another radiator to my existing central heating system.
I think my central heating system was installed in the late 70's early 80's its an open vented system but I'm not sure if it will still be a reversed return system (2 pipe parallel) or being a 70's installation...
