All this is further explained here. Hereof, do vertical radiators give out more heat?
If your radiators are vertical, they won't give out the same heat output as horizontal radiators as they don't have the same length to draw cold air up for convection.
Beside above, what is the best vertical radiator?
Just so, are column radiators more efficient?
A column radiator is a more efficient heater than other radiators, because they have more surface area which allows more air flow around the columns to heat during the convection process.
Which type of radiator is most efficient?
Best Radiator Materials The best cast iron radiators are very durable and offer excellent heat output which makes them ideal for putting anywhere. The best material for a modern radiator is aluminium. As we previously mentioned, Aluminium is better for heat transfer which makes Aluminium radiators incredibly efficient.
