Frequently Asked Questions about Compact Radiators from Columnrads UK.

What is the difference between K1, P+ and K2 Compact Radiators?

There are 3 types of Compact Radiator available at Columnrads UK.

Single Premium

  • Sometimes refered to as K1 or Single Panel, Single Convector radiators.

Double Premium

  • Also known as P+ or double panel, single Convector radiators.

The Panel is the front, ribbed facing of the radiator where the water channels are.

The Convector is the part behind the panel, or between the panels that is the sheet metal zig zaging which helps draw the cold air up from below, heating it as it rises.
