What is BTU?

BTU stands for British Thermal Unit and is a measurement of the heat content for fuels or energy sources. It is the quantity of heat that is required to increase the temperature of one pound of liquid by 1 degree Fahrenheit at the temperature that water has its greatest density.

All of our radiators are measured in Δ(Delta)50, with the exclusion of Reina radiators which are measured in Δ(Delta)70.
