Stelrad offers a wide range of high-quality single radiators, which are also known as Stelrad K1 radiators or single panel radiators. Our collection includes various sizes to fit your residential or commercial needs. Explore our K1 rad options today!

WHAT IS A SINGLE PANEL RADIATOR?

Single panel radiators are a common type of convector radiator found in typical UK households. They consist of one front panel and one row of convector fins, which are the zigzag metal structure located behind the panel. These fins increase the heated surface area and help circulate the air up and out of the radiator. The heated water warms the panel and fins, which in turn heats the air that circulates through the single radiator.

They are often referred to as single radiators or K1 radiators due to their one panel and one row of fins, making them a compact heat source that saves on space.

Single radiators are an affordable, effective, and dependable way to heat your home, which we also call Stelrad K1 radiators or Type 11 radiators in our listings. Many of our ranges include single panel radiators because a K1 rad is an affordable, effective, and reliable way to heat your home.

CHOOSING YOUR SINGLE PANEL K1 RADIATOR

When choosing a single panel Stelrad K1 radiator, it is crucial to ensure that it is the right size for the room in which it will be installed. Stelrad offers a wide range of single panel radiators in various sizes to accommodate the specific requirements of your space. To help you select the best single radiator for your room, we offer two useful tools: The Radiator Size Calculator and The Heat Loss Calculator.

The Radiator Size Calculator is designed to recommend single panel radiators that fit your available wall space. However, keep in mind that radiators of the same size can emit different amounts of heat, so it’s best to use this tool in conjunction with our Heat Loss Calculator.

The Heat Loss Calculator is an essential tool that measures the amount of heat required to warm your room. By using this calculator, you can determine the appropriate British Thermal Units (BTU) required for your space. This information will help you select the right size single panel radiator to meet your heating needs.

When exploring our website, it’s important to note that we may refer to a single radiator as a Stelrad K1 radiator or a single radiator. You can use the filters on our product range pages to find Stelrad K1 radiators or look for them specifically on the product page if it is available as a K1 rad. With Stelrad’s comprehensive selection of single panel radiators, you can find the perfect size and style to keep your space warm and comfortable all year round.

SINGLE PANEL RADIATOR SIZES

Radiator sizes will vary, depending on the type and model of radiator that you’re interested in. To choose the correct single panel radiator sizes for your home, you should use our radiator size calculator to check that you’re buying the right size.

You can filter Stelrad radiator sizes on this page by height or length, allowing you to choose the best radiator for your home. Whether you decide to purchase a Stelrad compact K1 radiator or like the look of our Flat radiator series, you’re sure to find the right radiator size here.

ALTERNATIVE TUBULAR SINGLE PANEL RADIATORS

The term “single radiator” can also describe a tubular style radiator with tubes on one side only. A striking example of this style is the Caliente Rail Coloured Radiator, available in 32 sizes and 36 different colours. This vertical single radiator offers both double and single radiator models, providing a range of options to suit your preferences. If you’re looking for a high-quality Stelrad K1 rad, consider purchasing the Caliente Rail Coloured Radiator today!

FAQs

SINGLE PANEL RADIATOR FAQS

Is a Single Panel Radiator the Same as a Single Column Radiator?

Open Close

A single panel radiator and a single column radiator are not the same thing. While a single panel radiator is a modern convection radiator that has one flat panel and fins, a single column radiator is an old-style radiator that has ridged sections of columns. The number of columns can vary from 1 to 4, but it does not have panels or fins. So, it’s important to distinguish between the two types of radiators when selecting the best option for your needs.

Is a Double Convector Radiator Better than a Single Radiator?

Open Close

When it comes to choosing between a double convector radiator (also known as K2 or double panel radiators) and a single panel radiator, the decision depends on your heat requirements and available space. 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 cases where a full-width double radiator would produce too much heat or a shorter one would look odd a single panel radiator is the better choice.

Fortunately, when you are browsing our standard radiators, you will see that there are plenty of models available, allowing you to choose the best option for your needs. By using the BTU heat loss calculator, you can determine which radiator is best suited to your room.
