The Revive2 600mm x 1000mm P+ Compact Radiator is a double panel, single convector (Type 21) central heating radiator that sits between a basic K1 radiator and a full K2 in both output and depth. A single full-depth convector fin between the two steel panels gives this size a rated output of 1362W (4647 BTU/h) at the industry-standard Delta T50 test condition — stronger heat than a single-panel radiator, in a slimmer body than a full double convector.
Finished in durable powder-coated white with factory-fitted top grille and side panels, the P+ compact suits domestic and light commercial installations on standard wet central heating systems, including bathrooms, hallways and bedrooms where a slightly shallower radiator is preferred. It is supplied complete with wall brackets, an air vent, a blanking plug and fixings, ready to plumb straight in.

Please Note
Heat output figures (1362W / 4647 BTU/h) are the BS EN 442 Delta T50 certified standard for a P+ (Type 21) double panel, single convector radiator at 600mm x 1000mm — the harmonised European test condition. Always confirm the exact figure on your order confirmation before final room heat-loss calculations, as coating batch and panel tolerances can cause minor variation between production runs.
Double Panel, Single Convector
P+ (Type 21) construction: two full steel panels with a single convector fin between them, giving higher output than a K1 single-panel radiator without the extra depth of a K2.
Shallower Than a K2
A single convector row keeps the overall depth down, making the P+ a good middle ground where wall projection is more limited than a standard double-convector radiator allows.
Factory-Fitted Top Grille & Side Panels
Integrated top grille and closed end panels give a tidy, finished look straight out of the box and help direct convected heat efficiently into the room.
BS EN 442 Tested
Manufactured and tested to BS EN 442, the harmonised European standard for radiator heat output, pressure and safety performance.
10 Bar Rated
Rated to a maximum operating pressure of 10 bar, giving it headroom for pressurised and unvented central heating systems as well as standard open-vent setups.
10-Year Manufacturer Warranty
Backed by a 10-year warranty against manufacturing defects, giving long-term peace of mind on a radiator built for everyday use.

Is this a P+ or Type 21 radiator?
Both terms describe the same construction. "P+" and "Type 21" are interchangeable industry names for a double panel, single convector radiator - two full steel panels with one convector fin between them, giving higher output than a K1 (Type 11) single panel radiator, in a shallower body than a K2 (Type 22) double convector.
How does P+ compare to K1 and K2 radiators of the same size?
For the same height and length, a P+ radiator generally outputs more heat than a K1 (single panel, single convector) but less than a K2 (double panel, double convector). P+ is a middle-ground option when you need more output than K1 but the wall space or budget doesn't suit a full K2.
What size room will this radiator heat?
At 1362W (4647 BTU/h), this size suits a room in proportion to its dimensions - smaller for a small radiator, larger for bigger sizes. Actual suitability depends on room volume, insulation standard, window area and target temperature, so we'd recommend running a proper heat-loss calculation for your specific room before ordering.
Does it come with a valve?
No. Radiator valves are sold separately so you can choose the type that suits your system - manual, thermostatic (TRV), or angled/straight/corner pattern to match your pipework.
Can this be used with a heat pump?
P+ compact radiators can be used on heat pump systems, but because heat pumps run at lower flow temperatures than a gas boiler, the actual heat output will be lower than the BS EN 442 Delta T50 figure quoted here. For heat pump installations, always size radiators against the manufacturer's low-temperature output data (typically Delta T30) rather than the standard Delta T50 rating.
