Type 11 normally means one water panel and one convector fin. Always confirm the manufacturer’s specification before comparing products.
Slimline Panel Heating for Smaller Wall Spaces
Wall depth matters in a narrow hallway or beside furniture. Single convector radiators combine one water panel with a rear convector, giving a slimmer profile than a double convector model. MacBlair lists Firefly and Myson Type 11 examples in several heights and widths as part of its plumbing and heating selection.
Choose by required heat output first, not by matching the old radiator's dimensions. A 500mm high panel in two different lengths can have very different ratings, and output falls when a heating system runs at lower water temperatures. Compare manufacturer figures at the relevant design temperature and allow clearance for circulation and cleaning.
Measure the position of existing pipework before a replacement. Valves, tails and brackets may not be interchangeable, so confirm what comes in the product pack. If old pipework needs adapting, see copper heating pipe and compression fittings; protect the system after filling with the specified heating inhibitor.
Single Convector Radiator FAQ's
They can be, if the rated output meets that room’s calculated heat loss at the system temperature. Room size alone is not enough to decide.
Only if the new model provides the required output. The same width in a single-convector format will usually produce less heat.
Measure width, height, available depth and existing pipe centres, then check connection size, bracket position and output rating.
Yes. Radiator output falls as the temperature difference between the panel and room narrows. Check the rating at your system’s design conditions.
