British Thermal Unit per hour is the standard measurement used to state the amount of output of any
heat generating device.
Is another measurement for heat output, 1 watt is equivalent to 3.412 Btu/hr.
Also known as Type K1, is a type of radiator with 1 radiator panel and 1 set of convection fins.
Also known as Type P+, is a type of radiator with 2 radiator panels and 1 set of convection fins.
Also known as Type K2, is a type of radiator with 2 radiator panels and 2 sets of convection fins.
Also known as Type K3, is a type of radiator with 3 radiator panels and 3 sets of convection fins.
Refers to the difference in temperature between the water circulating in the central heating system and
that of the ambient temperature. It is important to use the correct rt when selecting your radiators, as
the same radiator will have different outputs at different water temperatures.
rt50 is the UK standard, however Henrad also quote at lower levels for lower water temperature systems.
Is the amount of heat a room loses, it is therefore an important calculation when determining what size
radiator is required to heat a room to the correct level.
The warranty covers any defect that is attributable to a manufacturing, assembly or material fault, further
details available on request.
Is a set of International regulations related to quality management systems.
TBOE / BOE
Refers to which position the pipes are connected to the radiator, OE means opposite end i.e. 1 pipe
on each side, TB is top bottom i.e. 1 pipe is connected to the top and 1 to the bottom, B is both pipes
connected to the bottom.
EN 442 is the European standard which defines the manufacturing standards for radiators and
convectors which operate at temperatures of less than 120°C. The standard defines the type of steel
which must be used, the type of pressure testing which must be carried out and the accuracy of the heat
outputs quoted in the literature.
A European wide colour matching system.
British Standard Piping.
The CE marking is the manufacturers declaration that the product meets the requirements of the
applicable EC directive. This is applicable to all Henrad products.
