Will a 7000BTU vertical radiator (eg. 2m high x 40 cm wide) heat a 5 x 3 meters room as effectively as a 7000BTU horizontal rad (2 meters wide by 40 cm high)?
Some plumbers and radiator salesmen have told me that a horizontal rad will considerably outperform the vertical in terms of heat transferance to the entire room as, being nearer to the ground, its well placed to exploit the convection currents that will bring heat to the other end of the room (5 meters away..). Other plumbers (and the vertical rad sales man...) are insisting that the BTU value of the rad is the only thing I need to worry about and the vertical versus horizontal is a non consideration.
Who should I believe?
By the way, I will be placing the rad on the 3m non-exterior facing wall (ie The rooms window is on the 5 meter wall at the other end of the room from where I'm planning to put the radiator... ie the radiator will be placed at the naturally warmer end of the room..
