Radiator design & manufacturers

Radiators are designed to emit heat by radiation and convection. Radiators which have fin's welded to the rear of the radiator panel emit most of their heat via convection, with a small amount radiating direct from the steel panel. This leads to greater efficiency and a more even heat distribution throughout the room. Standard steel panel radiators which do not have fin's rely on radiant heat, this leads to less efficient localised heating and potential cold spots within the room.

Designs have evolved over the last 60 years to maximize efficiency and provide the maximum choice for the design engineer, however, the most common types of steel panel type radiators now available include:-

Outputs vary depending on a variety of differing factors and it is important to ensure that the radiator chosen is sufficient in size to adequately heat the room in question.

There is a variety of different categories of radiators which have been designed to satisfy specific market requirements. These radiator categories are in general terms modified variants of the traditional steel panel type of radiator.

This market has declined significantly after recent years as the compact radiator has increased in popularity. It should be noted that a round top radiator has three seamed edges as well as its rounded top: and due to its method of manufacture, a join is required on the corner where the round top meets the seamed edge this often creates problems for the aesthetics of the finished product.

Designed to conform to the NHS Estates health guidance note "Safe hot water and surface temperature" 1998 edition which states that heating devices should not exceed 43°C when the system is running at maximum design output. This is now the accepted standard not only within health care buildings, but also for local authorities and most commercial building applications. LST's are also proving popular in the domestic market being specified in children's bedrooms and nursery's, particularly if the occupant is disabled.
