Yes, that is exactly what I want to do but not what that last post is talking about.

He is talking about taking cold air from ground and putting it up high, etc.

I am very temptered to put two duct vents right infront of the Coonara and run it about 7-8 metres to the lower level master bedroom and babys room.

I've been ordered to get nice looking antique style vents if I am cutting two holes right infront of the Coonara in the loungeroom..lol

It has to surely work...The floor boards infront of the heater are toasty hot, air is getting pulled from there down 7m to another room...Has to work!!!
