Index Equivalence of direct radiation

Equivalence of direct radiation (EDR) is a standardized comparison method for estimating the output ability of space-heating radiators and convectors. [1]

Boiler

A boiler is a closed vessel in which fluid (generally water) is heated.

British thermal unit

The British thermal unit (Btu or BTU) is a traditional unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Condensation

Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vapourisation.

Convection heater

A convection heater is a heater which operates by air convection currents circulating through the body of the appliance, and across its heating element.

Pounds per square inch

The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units.

Radiator

Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating.

Radiator (heating)

Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another for the purpose of space heating.
