What Are Single Panel Radiators?

Single panel radiators are a slimmer type of convector radiator,  consisting of one front panel and one row of convector fins behind it. Whilst having a slim profile, the fins increase the heated surface area, helping to circulate air up and out of the radiator, ensuring optimal performance. Often referred to as single radiators or K1 radiators due to their one panel and one set of fins, they are a compact heat source that saves on space, ideal for smaller rooms a minimalist interior design.

They are an affordable, effective, and dependable way to heat your home. You can discover which of our single panel radiators are best for a particular room using our heat loss BTU calculator. This way, you can match the perfect size for efficiency based on the appropriate British Thermal Units (BTU) required for your space, making it even easier to choose the right radiator.

Single Panel Radiator Sizes

As room sizes differ across UK homes, so do our single panel radiators. Finding the right dimensions to fit a room whilst also working efficiently is made easier thanks to our range of sizes across each model.

To help you do so, our radiator size calculator will help you check that you’re buying the right size every time for your available wall space. All you need is the height and length in millimetres that you need, and we’ll show you which of our single panel radiators are the right match. It’s important to keep in mind that radiators of the same size can emit different amounts of heat, so using this tool in conjunction with our heat loss calculator can provide the best recommendations.

You can also filter radiator sizes in the product menu above to refine your search further and choose the exact size on the product page before adding it to your basket. If you have any questions about selecting the right sizes, please don’t hesitate to contact us. It’s important to choose the right size so that the radiator can work as optimally as possible, so please let us know if we can help further.

FAQs

Single Panel Radiator FAQs

Is a single panel radiator the same as a single column radiator?

Open Close

Whilst you can choose ‘single radiator’ versions on some models, a single panel radiator and a single column radiator are different. While a single panel radiator has a flat or ridged front panel that has one panel and a set of fins, a single column radiator has a more traditional column design that has separate sections of columns. The number of columns can vary from 1 to 4, but they do not have a front panel. Which you choose comes down to personal preference, so it’s best to compare and check you have the right dimensions and BTU output for your room before purchase.

Is a double convector radiator better than a single radiator?

Open Close

A double convector radiator (also known as K2 or double panel) can provide a higher heat output than a single panel radiator, but which you choose will come down to the size of the room and the heat output you require. A double convector radiator has a second row of fins between the front and rear panels, providing more surface area to emit heat and more convection fins to distribute it. However, it also takes up more room due to its thickness.

If you prefer a more streamlined look or need a compact radiator, a single panel radiator may be the better option. In rooms where a double radiator would produce too much heat or wouldn’t suit the space, a single panel radiator can be the better choice. Use our BTU calculator to determine which would be ideal for your exact room requirements.

What are the advantages of having a single panel radiator?

Open Close

Single panel radiators have a slim profile which means they take up less space compared to other radiator designs. This makes them ideal for smaller rooms or tight spaces in the home like a hallway where conserving space is crucial. They are also easy to install and maintain due to their simpler design, as long as you choose the right size for your room.

How do I choose the right size single panel radiator for my room?

Open Close

The size of the radiator should match the heating requirements of your room, and you can easily calculate this using our BTU calculator. This will consider the room dimensions (height, width, and length), window size and type, insulation quality, and other room features. That way, you can avoid purchasing a radiator that is too small to heat the room efficiently or too large for the room.
