Buying Type 20 Radiators: Quick Tip

Type 20 means two panels and no convector fins. That gives you a handy output boost over a single panel, but with a simpler build that’s often easier to wipe down. If you’re close to your BTU/Watts target and want a bit more punch, a Type 20 can work well — but if you need faster warm-up or higher output in the same size, a Type 21 or Type 22 will usually deliver more.

Who Should Buy a Type 20 Radiator?

And who should consider alternatives

✔
Who Should Buy

Homes with wet central heating

A great match if you already have a boiler and water-filled pipework. Type 20 radiators are a straightforward swap-in choice for many standard UK systems.

Want more output without fins

The double panel design provides stronger heat than a single panel radiator, while keeping the internal build simpler than finned convector models.

Prefer easier cleaning and less dust build-up

With no convector fins, there are fewer tight gaps to trap dust. That can make Type 20 radiators appealing in busy family homes or rooms you like to keep low-maintenance.

✘
Who Shouldn't Buy

Need maximum heat from limited wall space

If you’re short on wall length or need high output for a larger room, a Type 21 or Type 22 often delivers more heat in the same width and height thanks to the added convection fins.

Properties without a wet heating system

Type 20 radiators must connect to a boiler and pipework. If you don’t have central heating installed, electric radiators or wall-mounted heaters are usually the better fit.

You want a statement radiator style

Type 20 models are all about practicality. If you’re aiming for a feature look, consider vertical radiators, designer panels, or traditional column styles instead.

FAQs About Type 20 Radiators

Help with choosing, sizing and performance

  • What is a Type 20 radiator?

    A Type 20 radiator is a double panel radiator with no convector fins. The two panels increase the heating surface compared with a single panel model, providing a useful step up in heat output while keeping the design relatively simple and easy to clean.

  • What is the difference between Type 20 and Type 21 radiators?

    The key difference is convector fins. A Type 20 radiator has two panels and zero fins, while a Type 21 has two panels with one set of convector fins. Because fins boost convection, Type 21 models usually deliver higher heat output than Type 20 in the same width and height.

  • Where are Type 20 radiators best used?

    Type 20 radiators are well suited to bedrooms, kitchens, hallways and family spaces where you want steady, comfortable warmth without the added convection fins. They’re also popular in homes where easier cleaning and a less dust-trapping design are priorities.
