Type 22 Double Panel Convector Radiators
Based on your preference, I’ve matched Type 22 panel radiators to each room’s heat loss calculation. These are the highest-output standard panel type — double panel + double convector for maximum heat. All white finish, includes brackets & fixings.
Heat Loss Summary
Calculated per BS EN 12831 with 15% safety margin. End-of-terrace (1952): 3 external walls, solid brick U=2.1, double glazing U=1.4. Loft uninsulated U=2.3, suspended timber floor U=1.5.

Pro Tip: Type 22 panel radiators have standard side connections, so if your current radiators are a similar height (600mm or 700mm), existing pipework can usually be reused — making installation quick and straightforward. A standard swap is often all you need.
Please let me know if you want me to change the radiator models or sizes.
