A 400 high x 500 long K1 single panel single convector compact radiator is a type of heating appliance designed to heat a room efficiently.

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

Panels and Convectors: Compact radiators feature one or more panels (flat surfaces) and convectors (corrugated surfaces).

K1: This refers to the type and configuration of the radiator. "K1" means it has a single heating panel and a single convector. The convector is a piece of metal that increases the surface area of the radiator, helping it to emit more heat.

Enhanced Heat Output: Compact radiators are designed to provide high heat output. The use of panels and convectors helps in maximizing heat transfer.

Energy Efficiency: Modern compact radiators are designed to be energy efficient, helping to reduce heating costs while maintaining a comfortable indoor environment.

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.
