Radiators
Radiator Design
For Double Panel Single Convector Radiators Type 21, a Type 21 panel radiator has two panels and one set of convector fins. Compare its depth and output with the space available. Choose the wall position before comparing the profiles. Horizontal radiators can sit below a window, while a tall model can make use of a narrow wall. Compare a radiator’s depth with nearby doors and furniture as well as its overall height and width.
Size & Heat Output
Check the room’s heat requirement and compare radiator outputs at the same stated temperature difference. Two radiators with similar outer dimensions can give different outputs depending on their construction. Include the valves and any pipe clearance when checking the available space. Use the individual size variant’s rating when a product comes in several sizes.
Connections & Finish
Check the pipe centres and connection position before replacing an existing radiator. Compare the finish beside the valves you intend to use, and read the listing to see whether brackets and other fittings are supplied. Electric models have their own power and control requirements. If pipework will be visible, compare the finish of the valves and any pipe covers together.
