The Revive2 600mm x 800mm K1 Compact Radiator is a single panel, single convector (Type 11) central heating radiator built for the slimmest possible profile in this range. One steel panel with a single convector fin gives this size a rated output of 700W (2389 BTU/h) at the industry-standard Delta T50 test condition — a straightforward, cost-effective option for smaller rooms or supplementary heating.
Finished in durable powder-coated white with factory-fitted top grille and side panels, the K1 compact keeps its wall projection to a minimum, making it a practical choice for tight spaces such as hallways, cloakrooms and behind doors. 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 (700W / 2389 BTU/h) are the BS EN 442 Delta T50 certified standard for a K1 (Type 11) single panel, single convector radiator at 600mm x 800mm — the harmonised European test condition (mean water temperature 70°C against a 20°C room). 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.
Single Panel, Single Convector
K1 (Type 11) construction: one steel panel plus one convector fin, giving the slimmest and most economical option in the compact range.
Minimal Wall Projection
The shallowest profile of the compact range, projecting only around 84-95mm from the wall including brackets - ideal for narrow hallways and behind doors.
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 K1 or Type 11 radiator?
Both terms describe the same construction. "K1" and "Type 11" are interchangeable industry names for a single panel, single convector radiator - the slimmest and most economical configuration in this range, with lower output than a P+ (Type 21) or K2 (Type 22) radiator of the same dimensions.
What size room will this radiator heat?
At 700W (2389 BTU/h), this size is best suited to a small room, a supplementary heat source, or a space with modest heat loss. 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.
Why choose K1 over a P+ or K2 radiator?
K1 is the shallowest and most budget-friendly option in the range. It's a good fit where wall projection is very tight, for smaller or well-insulated rooms, or as a secondary radiator where high output isn't the priority.
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.
