Radiator choices
Radiators are a staple in every room of the home. You might picture the classic white single-panelled radiator from your childhood, but designs and trends have evolved significantly.
Before purchasing a new radiator for your home, you need to consider several factors. The size, shape, and heat output are crucial when selecting the best radiator. Additionally, style, material, and finish are important aspects to think about.
At Designer Heating, we offer a wide range of designer, contemporary, and traditional radiators, including colosseum, floor-standing, and classic styles. We cater to everyone and every room, providing both affordable and high-end options.
What size of radiator do I need?
One of the initial things to consider is the size of the room you are looking to heat - as it determines the space available for the radiator. Larger rooms in your home require more heat to stay warm throughout the year, making this an important consideration. Larger rooms can benefit from 2-3 large radiators, while a smaller room may only need 1 small radiator.
The size of the radiator needed depends on several factors including the desired maintenance temperature and the extent of heat loss, which is the temperature you want to maintain and the amount of heat that escapes from the room. The shape and size of your radiator will also influence its placement within the room.
To determine the appropriate radiator size, you first need to calculate the BTU (British Thermal Unit).
BTU Requirements
One of the most important factors when choosing your new radiator is making sure you know the total amount of BTU’s for the room. The BTU (British Thermal Unit) measures the heat output required for your room and helps determine the appropriate radiator size. Check out our BTU calculator to assist you in figuring out the right radiator size for your space. These calculators consider various factors, such as room size and location.
A higher BTU indicates greater heat output. Accurate calculations can save you both money and energy. Your plumber can also provide recommendations on the ideal BTU for your home.
The BTU of each of our radiators is displayed within the specifications on their individual product page.
Where should I hang my radiator?
Another factor to consider when choosing your new radiator is where you would like it to hang in the room. The type of wall it is going to hang on can determine the best size and style for the room, for example, if the wall is solid masonry or brickwork, you will have a wider selection of radiators to choose from as this wall structure can support all types of radiators including larger radiators.
However, if the wall is plasterboard or hollow behind, your radiator will need to hang from where the studs are within the wall, as this will be the strongest part.
You should also avoid placing your radiator behind large items of furniture as this can affect heat circulating around the room.
Existing pipework considerations
When choosing a new radiator, you’ll also want to consider where your existing pipework is positioned – does it run along the wall or come up from the floor?
Measuring and Planning
Take some time to measure the area where you plan to install the radiator. Note the following:
Types of radiators
When first selecting a radiator, you will typically have to choose between either a plumbed or electric version. If you’re replacing an existing radiator then you’ll likely want to use the same system as you already have.
Central heating radiators: These make use of the hot water supply from your boiler, circulating it through the pipes.
Electric radiators: This type of radiator is controlled individually and works independently from your central heating. They can be particularly appealing in areas such as loft extensions or conservatories, where your plumbed central heating doesn’t currently run, as the only require a mains electricity supply.
Dual fuel radiators: You can add a heating element to your current plumbed radiator which will allow it to work independently to your central heating. This means you have the option of having a single radiator turned on in a selected room without having to turn on your full central heating system. We recommend speaking with a specialist to confirm if your current radiator can be turned into a dual fuel radiator.
Are radiator valves required?
The short answer is, yes! Valves regulate the flow of water into the radiator and consequently control the amount of heat emitted by the appliance. The type of radiator valves required depends on the positioning of your pipes and their connection points to the radiator.
Selecting the correct valve type ensures efficient operation and proper integration with your radiator setup, ensuring optimal heating performance. For more detailed information regarding radiator valves read our buying guide here.
Material and style of radiators
Radiators are typically made of steel for its strength, durability, and efficiency. While white is a common colour, we offer a variety of finishes for your radiator including black, brushed brass, chrome, anthracite, and more, meaning you can match your personal preference and style.
Cast iron is another material choice and is perfect for vintage or period properties. It is a heavyweight option, so you’ll need to ensure your walls and floor are structurally sound, however the radiator has the benefit of retaining heat for longer after it is turned off.
Orientation
There are two main radiator orientations:
Tall vertical radiators are excellent for kitchens, creating more wall space for your cabinets and appliances. They can also create the illusion of higher ceilings.
Horizontal radiators are well suited for placement beneath windows in living rooms and bedrooms.
For a selection of our radiators, a set of radiator brackets can be purchased separately and will allow you to change the orientation of your radiator with ease. This means you can turn your vertical radiator into a horizontal radiator.
Ultimately, the choice between vertical and horizontal radiators comes down to your own personal preference, room layout and available space.
Traditional or Modern
The design of your home plays a crucial role in choosing between a traditional or contemporary radiator. Floor-standing radiators imbue a classic, period style, ideal for enhancing a traditional room setting.
For more contemporary homes, a sleek black vertical radiator introduces a sophisticated, modern flair, perfect for those seeking a more modern aesthetic.
At Designer Heating, we offer a diverse selection of radiators tailored to accommodate various styles and preferences. Whether your preference leans towards timeless elegance or cutting-edge design, we are committed to offering a radiator that aligns seamlessly with your homes vision.
Column radiators
Column radiators are made up of a vertical row of hollow tubes joined at the top and bottom. They are available in a wide range of styles and finishes and come either horizontal or vertical.
Floor standing radiators
A showstopping piece, a floor standing radiator can add a more traditional look to your home. They are versatile and offer flexibility in design and placement and can often become a focal point in any room.
Heated towel rails
Heated towel rails, or ‘towel radiators’ are the best type of radiator for a bathroom. They provide ample space for you to hang your towels to keep them warm, whilst also heating the room.
Designer radiators
Designer radiators are becoming increasingly popular for their variety of designs, adding a luxury look and feel to your home.
Radiator types – Convectors
What exactly is a convector radiator? Well, they are a type of radiator that heats rooms through way of convection. This means they warm up rows of fins that heat the air inside the radiator, allowing it to escape through vents typically located at the top.
They are named depending on how many panels and fins they are made up of. The first number represents how many panels, whilst the second represents the number of fins.
The more panels and fins, the higher the heat output.
Type 11 – Also known as single panel radiators, they have one panel and one set of fins.
Type 21 – A double panel radiator: two panels with one set of fins in the middle.
Type 22 – Also a double panel radiator with two sets of fins, providing more heat due to the additional fins.
Type 33 – A triple panel radiator, consisting of three panels with three sets of fins.
Radiator types by room
The type of radiator you choose often depends on the specific room you are looking to heat, as different rooms may require different radiator types. At Designer Heating we are proud to offer a vast selection of radiators to suit every room in your home, from bathrooms, living rooms, bedrooms and kitchens, to dining rooms, conservatories, the home office and nursery, as well as basement and loft conversions.
Bathroom radiators:
A top choice for bathrooms is heated towel rails. These feature multiple bars where towels can be placed to stay warm and cosy, perfect for post-shower comfort. They offer excellent heat output, ideal for drying damp towels and warming the bathroom effectively. Towel rails can be floor standing or wall-hung and are popular as a modern bathroom heating choice.
Living room radiators:
Living rooms typically benefit from large horizontal or vertical radiators with substantial heat output. You might opt for a statement piece to highlight a specific area, or a discreet plain white convector radiator tucked neatly under a window, blending seamlessly into the decor.
Bedroom radiators:
For bedrooms, a compact radiator that conserves wall space is ideal. A tall vertical radiator offers an unobtrusive yet powerful heating solution.
Kitchen radiators:
Ideal kitchen radiators are often tall and slim, making them perfect for fitting snugly between kitchen cabinets and appliances. Their increased height also ensures excellent heat distribution throughout the whole room.

Radiator FAQs
- How do I bleed my radiator?
Bleeding a radiator involves releasing any trapped air that may be preventing it from heating up properly. To bleed a radiator, turn off the heating, locate the bleed valve (usually at the top of the radiator), use a radiator key or a flat screwdriver to turn the valve counterclockwise until you hear a hissing sound (air escaping). Then, once water starts to trickle out, close the valve by turning it clockwise. - Why is my radiator not heating up?
There could be several reasons why a radiator is not heating up, including trapped air, a closed valve, a faulty thermostat, or sludge buildup. First, check if the valves are open. If they are, try bleeding the radiator to release any trapped air. If the problem persists, it may require professional help and maintenance. - What is the difference between single and double panel radiators?
Single panel radiators (also known as Type 11 radiators) have one panel and one set of fins, while double panel radiators (Type 21 or 22) have two panels and either one or two sets of fins. Double panel radiators provide more heat output compared to single panel radiators, making them more suitable for larger rooms or spaces with higher heat requirements.
- Can I paint my radiator, and if so, how?
Yes, you can paint your radiator. It's important to use paint that is suitable for high temperatures, such as radiator enamel. Before painting, turn off the heating and let the radiator cool down. Clean the surface thoroughly to remove any dust or rust and apply a primer if needed. Then, apply the radiator paint in thin, even coats, allowing sufficient drying time between coats.
