What’s the difference between a radiator and a convector?
Radiant heat and convective heat
Radiant heat is the type of heat that can be felt by the body. This can be compared to the thermal radiation from a bonfire or from the sun. In reality, only Type 10 panel radiators reach a radiant heat proportion of 50%. Already type 11, which is a radiator with a single convector plate and single water-bearing panel, has a convection proportion of approximately 70%.
A convector is often lower than 30 cm in height, which means it occupies less vertical space and makes it suitable in front of large windows. A convector primarily emits convective heat, often over 90%.
