Buying Type 22 Radiators: Quick Tip

Type 22 is the “power option”: two panels plus two sets of convector fins. That extra finned surface area means higher BTU/Watts in the same width and height — ideal when you’re short on wall space but still need serious output. Just remember Type 22 radiators are usually deeper, so check clearance behind doors, furniture, and window sills before you buy.

Who Should Buy a Type 22 Radiator?

And who should consider alternatives

✔
Who Should Buy

Need high heat output in limited wall space

A brilliant choice for larger rooms or colder areas where a smaller radiator type won’t meet the BTU/Watts target. Type 22 models pack strong output into a compact footprint.

Upgrading a wet central heating system

Ideal for homes with existing boiler and pipework. Switching to Type 22 radiators can be an effective upgrade when you want more warmth without extending pipe runs or adding extra radiators.

Rooms with higher heat loss

Great for spaces with large windows, external walls, or poorer insulation where you need faster warm-up and higher output to stay comfortable during colder weather.

✘
Who Shouldn't Buy

Tight spaces where depth is an issue

Type 22 radiators typically project further from the wall. If clearance is limited (behind doors, narrow corridors, or near furniture), a Type 21 or Type 11 may be a better fit.

Homes without a wet heating system

These radiators must connect to a boiler and water pipework. If you don’t have central heating installed, electric radiators or heaters are generally easier and cheaper to set up.

Low-heat rooms where a slimmer radiator will do

For small bedrooms, box rooms, and well-insulated spaces, Type 22 can be more output than you need. A slimmer type can look neater and still meet the required heat level.

FAQs About Type 22 Radiators

Help with choosing, sizing and performance

  • What is a Type 22 radiator?

    A Type 22 radiator is a double panel, double convector radiator. It has two panels and two sets of convector fins (typically one set attached to each panel), which increases surface area and boosts airflow. This design delivers high heat output and helps rooms warm up quickly.

  • Are Type 22 radiators better than Type 21 radiators?

    Type 22 radiators usually produce more heat than Type 21 radiators of the same width and height because they have an extra set of convector fins. That makes them a strong choice for larger rooms or higher heat-loss spaces. However, they are typically deeper, so Type 21 can be better where wall projection is a concern.

  • How do I choose the right size Type 22 radiator?

    Work out the heat requirement for your room in BTUs or Watts by considering room size, insulation, glazing, and external walls. Then choose a Type 22 radiator with an output that matches or slightly exceeds your target. If you’re limited for wall length, Type 22 models are often an efficient way to achieve higher output without going taller or wider.
