Type 33 (K3) Radiators Popular Questions

What makes Type 33 (K3) radiators different from other types?

Type 33 radiators have three panels and three convectors, compared to Type 21 (P+) or Type 22 (K2). In other words, it produces more heat than Type 21 (which has one convector) or Type 22 (which has two convectors). The unit is bulkier, but it is more efficient when it comes to heating large areas.

Can Type 33 (K3) radiators be custom painted?

Type 33 radiators come in a variety of standard finishes, including white. However, we offer a colour matching service if you would like to choose a custom finish that matches your decor. If you would like to find out more, please get in touch with one of our experts today.

Do Type 33 radiators take up more space?

Due to their three panels, they are generally thicker and take up more wall space than their alternatives (Type 21 or Type 22). To ensure the radiator fits comfortably, you'll need to ensure that you have adequate wall space.

Are they energy efficient?

Due to their high heat output and ability to quickly warm a room, these radiators can be highly energy efficient. Although they may take a little longer to heat up than radiators with fewer panels, once they are warm, they can be used effectively to maintain a consistent temperature.

How do I choose the right size for my room?
