Buying Convector Radiators: Quick Tip
When you buy a convector radiator, check whether it’s Type 11, Type 21, or Type 22. The number tells you how many panels and convector fins it has — more fins usually means more heat output for the same width and height. Convector models also have different depths from the wall, so if you don't want one to stick out from the wall type 11 is better, if you want more heat type 21 and 22 will do the job. Match the type to your room’s BTU/Watts target so you don’t under-size.
Who Should Buy a Convector Radiator?
And who should consider alternatives
Who Should Buy
Existing wet central heating system
Ideal if you already have a boiler with hot water pipes (gas, oil, or heat pump). Convector radiators are easy to install as replacements or upgrades and deliver higher heat output than basic panels.
Need fast and powerful room heating
The convector fins create rapid air circulation — perfect for quickly warming medium to large rooms, living areas, or homes where you want instant warmth.
Prioritise efficiency and great value
Excellent performance with modern low-temperature boilers and heat pumps, giving you strong BTU output at an affordable price.
Who Shouldn't Buy
No existing plumbing or central heating
Convector radiators require connection to a boiler and pipes. If your home has no wet system (e.g., off-grid), installation is costly and disruptive — choose electric heaters instead.
Can't afford professional plumbing work
Extending or adding pipework needs a qualified plumber. Plug-in electric panel or fan heaters are far simpler and much cheaper to set up.
Design and aesthetics are important
Standard convectors are practical but plain. If you want a stylish feature, consider designer, vertical, or column radiators that look better in modern or traditional interiors.
FAQs About Convector Radiators
Help with choosing, sizing and performance
-
What is a convector radiator?
A convector radiator is a type of panel radiator featuring metal fins attached behind the front panel. These fins significantly increase the surface area, enhancing convection by drawing in cool air, heating it quickly, and circulating warm air more effectively throughout the room for faster and more even heating.
-
How do I choose the right size convector radiator for my room?
To choose the right size, first calculate your room's required heat output in BTUs or Watts using factors like room dimensions, ceiling height, insulation quality, windows, and location. Online BTU calculators can help, then select a convector radiator model with an output rating that matches or slightly exceeds your calculated needs for optimal comfort.
-
Do convector radiators give more heat than flat panel radiators?
Yes, convector radiators typically provide more heat than basic flat panel radiators of the same size because the added convection fins boost the effective surface area and improve air circulation. This results in higher BTU/Watt output and faster room warming, making them ideal for rooms needing greater heating performance without increasing the radiator's footprint.
