The Revive2 700H X 800L Double Panel, Double Convector K2 Compact Radiator is a type of central heating radiator designed for use in residential or commercial heating systems.

compact radiators are the most common type of radiator used in central heating systems to distribute heat throughout a building.

Double Panel: The radiator has two panels (flat surfaces) which increase the surface area for heat emission.

Double Convector (K2): It includes two convectors (corrugated surfaces), one attached to the back of each panel. This design enhances the radiator's ability to convect heat into the room, making it more efficient.

Space Saving: Because the K2 range gives out more heat than a K1 or P+ compact radiator but not as much as a K3 of the same dimensions, you can have a smaller K2 radiator, saving wall space but still get enough heat output to heat the room.

Efficiency: The double panel and double convector K2 design means this radiator can emit a significant amount of heat relative to its size, making it an efficient choice for heating. 

Versatility: They can be installed in various settings, including homes, offices, and commercial spaces. The extensive range of sizes make them especially ideal for rooms, such as bathrooms, hallways, and kitchens.

Compact radiators are commonly used in residential and commercial buildings where efficient use of space and effective heating are important considerations. With a huge range of sizes, they are particularly useful in rooms where traditional, larger radiators would be impractical or take up too much space.
