Frequently asked questions – Type 33 convector radiators

What makes Type 33 convector radiators different from other types?

Type 33 radiators feature three heating panels and three sets of fins to maximise surface area and speed up heat delivery. They warm rooms more quickly and efficiently than smaller models like Type 11, Type 21 and Type 22.

Are Type 33 radiators energy-efficient?

Yes. Their enhanced surface area improves heat transfer and helps maintain steady room temperatures with less energy. Correct sizing using the BTU calculator further improves efficiency.

Can I use a Type 33 radiator in a small room?

Absolutely. The compact depth relative to output makes Type 33 a smart choice for smaller rooms that still need higher heat. If wall space is very limited, also consider our central heating range for alternative sizes and outputs.

How do I choose the right size Type 33 radiator for my room?

Measure the room and insulation quality, check wall types and what is above and below the room, then use our BTU calculator to find your required output. For extra guidance, visit the Advice Centre.

Can Type 33 radiators be used with any heating system?

Type 33 convectors are compatible with standard wet central heating systems (combi or conventional). Explore valves and controls in our radiator valves & accessories ranges.

Are these radiators easy to install?

Installation is straightforward for a qualified professional and follows standard panel radiator fitting practices. For balancing tips after installation, see our guide to balancing radiators.

How do I maintain my Type 33 convector radiator?

Maintenance is minimal. Regular dusting and keeping fins clear maintains performance. Visit the Advice Centre for cleaning and maintenance tips.

Can I adjust the heat output of a Type 33 radiator?

Yes. Fit thermostatic radiator valves (TRVs) to control room temperature and optimise energy use.
