Looking for the best radiator for your living room, bathroom or kitchen? There’s lots to consider – including the size of the room, the heat output needed, and the style you’re after.

 

The most common radiator types are single (Type 11), double (Type 22), and double plus (Type 21) steel panel central heating convector models.

 

Smaller rooms will suit Single Panel radiators – while Double or Double Plus are best for medium-to-large rooms.

 

Recently, designer radiators such as dual-fuel and electric-powered towel warmers, and vertical radiators have grown in popularity – offering high-powered heating without sacrificing style.

Convector Radiators

Convector radiators, also known as convection radiators, circulate hot water through a tube surrounded by metal convection fins. These fins conduct heat from the tube and create a larger surface area with the surrounding air – allowing them to heat your rooms incredibly quickly.

 

Here at Toolstation, you’ll find convector radiators in three main types: Single Panel (type 11 radiators), Double Panel (type 22 radiators), and Double Panel Plus (type 21 radiators).

Single Panel Radiators (Type 11)

Single Panel Radiators (Type 11)

Single Panel radiators, also known as Type 11 radiators, have a single, glossy metal panel with convection fins bolted on the back side – perfect for efficiently and affordably heating smaller rooms such as bathrooms or narrow hallways.

 

With only a single panel and layer of convection fins, Type 11 radiators are incredibly slim, too – helping to free up valuable space in narrow hallways and rooms with a smaller footprint.

 

They’re best suited to smaller rooms because they emit less heat – you’ll want to upgrade to a double panelled model if you’re heating anything much larger than a bathroom.

Advantages

  • >

    An economical radiator for smaller rooms

  • >

    Slimline design fits rooms running low on space

  • >

    Impressive heat output despite slimmer size

Things to Consider

  • >

    Lower heat output than Type 21 and Type 22 models

  • >

    Less suited for medium to large rooms

Shop Type 11 Radiators
Double Panel Plus Radiators (Type 21)

Double Panel Plus Radiators (Type 21)

Double Panel Plus radiators, sometimes called Type 21 radiators, have a glossy metal heating panel on the front and back, and one layer of convection fins.

 

Type 21 radiators have a higher heat output than single panel models thanks to the extra surface area from the second panel, making heating larger rooms kinder to your wallet.

 

There’s only one layer of convection fins with Type 21 radiators so less hot air is moved around – meaning the heat output isn’t as high as Type 22 models.

Advantages

  • >

    Higher heat output than Type 11 radiators

  • >

    Slimmer than Type 22 models

  • >

    Will save money in the long run through efficient heating

Things to Consider

  • >

    Lower heat output than Type 22 models

  • >

    Higher initial cost than Single Panel radiators

Shop Type 21 Radiators
Double Panel Radiators (Type 22)

Double Panel Radiators (Type 22)

Double Panel, also called Type 22 radiators or simply double radiators, have a glossy metal panel on the front and back, and two layers of convection fins in-between. They offer a higher heat output than single panel models because of the extra surface area from the second layer of fins.

 

They’re an economical option for medium-to-large rooms thanks to their higher heat outputs – warming quickly to limit the time your central heating is kept on.

 

Type 22 radiators have a higher price tag than single panel models – reflecting their power. They also have more depth because of the extra layer of convection fins, making Double Panel radiators less suited for narrow spaces.

Advantages

  • >

    Higher heat output than Single Panel radiators

  • >

    An economical option for medium to large rooms

Things to Consider

  • >

    Cost reflects the greater heat output

  • >

    Thicker design less suited for narrow spaces

Designer Radiators

Looking for radiators that’ll bring more than just heat to your rooms? Then our statement-making, high-power designer radiators are the perfect choice for you!

 

At Toolstation, you’ll find everything from designer vertical radiators to towel warmers – all available in a range of styles, colours, powers and sizes to best suit your space.

Vertical Designer Radiators

Vertical Designer Radiators

Vertical designer radiators combine modern style with a tall, slim design – ideal for rooms needing a high heat output but running low on wall space. Pairing with a dual-fuel valve means they can be powered by central heating or electricity – ideal for summer months when your central heating is off.

 

You may be wondering – since heat rises, are vertical radiators less efficient? The answer’s no! As the air gets to a higher temperature and moves faster, it’ll travel quickly around the room instead of rising to the ceiling.

 

Upgrading from a panelled convector radiator? Switching to a designer vertical radiator may require pipes to be moved around. Additionally, these types of radiators cost more than standard panelled models – reflecting their powerful and stylish designs.

Advantages

  • >

    Attractive, modern style to compliment a room

  • >

    Versatile for all room types

  • >

    High heat output, via electric or central heating

Things to Consider

  • >

    Higher price to reflect quality and heat output

  • >

    Newer – more difficult to find like-for-like replacements

  • >

    Panel to vertical radiator upgrade means moving pipework

Horizontal Designer Radiators

Horizontal Designer Radiators

Horizontal designer radiators are a modern, more attractive alternative to steel panel radiators – with a high heat output for medium-to-large rooms.

 

There are a large range of styles, sizes and colours of horizontal designer radiators available, so you can find the perfect model for each room in your home, without compromising on space or aesthetics.

 

Like vertical designer radiators, they have a higher price tag to reflect their power and modern appearance, but unlike vertical radiators, they’re best suited for larger rooms where space-saving isn’t crucial.

Advantages

  • >

    High heat output

  • >

    Large range of colours, styles and sizes

  • >

    Easier to upgrade from steel panel types than vertical radiator types

Things to Consider

  • >

    Higher price tag to reflect power and aesthetic

  • >

    Less space-efficient than vertical models

Column Radiators

Column Radiators

Column radiators are traditional-looking models made up of hollow, vertical tubes. The ‘columns’ work to warm the surrounding air – with the space between each tube creating a large surface area for high-power heating. Despite their vintage look, column radiators are very efficient and can match the heat output of other modern radiators.

 

These types of radiators have the flexibility for wall-mounting or floor standing. And, with a range of shapes, colours, finishes and styles available, you’re bound to find the perfect model for your space.

 

The surface of the radiator can also get very hot meaning they come with a higher risk. Additionally, column radiators, especially if floor standing, are bulkier – so they’re less suited for rooms running low on space.

Advantages

  • >

    Attractive, traditional style

  • >

    Wide range of styles, colours and sizes

Things to Consider

  • >

    Bulkier than some designer and panel alternatives

  • >

    Surfaces can get hot – increasing risk

Towel Radiators

Towel Radiators

Towel radiators are used to dry wet towels (reducing mildew) and heat bathrooms. While towel warmers are usually smaller than traditional radiators, their sleek designs will help to spruce-up your bathrooms in a big way!

 

You’ll find a range of sizes, BTU outputs and styles on offer – including flat ladder, curved ladder or traditional column models – so you’ll always find the perfect radiator for your space.

 

Towel radiators can get hot, which can be risky, especially if you have young children – you’ll find Low Surface Temperature alternatives if this is a concern. They can also be difficult to move if you want to redesign your bathroom because pipework may need to be rearranged.

Advantages

  • >

    Reduces mildew growth on towels

  • >

    Makes bathrooms more comfortable in winter

  • >

    Large range of sizes, power and styles

Things to Consider

  • >

Radiator Power Sources Explained

Central Heating Radiators

As the name suggests, central heating radiators are powered by a plumbed-in hot water central heating system. Central heating radiators work by filling up with hot water to heat the metal, which is then radiated into the room.

 

They’re fully controllable, meaning you can set each room to a different temperature and schedule different times to heat a room.

Electric Radiators

Electric radiators are filled with a heat-conducting oil or glycol, and use electricity to efficiently heat a long metal rod inside – converting all of the energy used into heat to radiate throughout rooms.

 

Installation is simple and inexpensive because you don’t need to lay pipework – although you will need an electrician to install the radiator into the electrical system with an isolation switch. After installing the radiator, very little maintenance is needed.

 

Each radiator is powered individually rather than centrally. Thermostatic versions allow you to control the temperature via the heating element, others allow you to set schedules and timers, and some can even be controlled with smart Bluetooth thermostats.

Dual-Fuel Radiators

Dual-fuel radiators can be powered with central heating or electrics with the simple addition of a heating element and a dual-fuel radiator valve.

 

As long as the heating element is fitted safely, most radiators can be turned into a dual fuel model.

 

Towel radiators in bathrooms and ensuites are often dual-fuel so you can still use them in summer when the central heating is off to dry your towels and reduce mildew.

Key Radiator Features

BTU

BTU stands for British Thermal Unit, which represents the amount of energy taken to heat a pint of water by one degree fahrenheit. Every radiator has a BTU – the higher the BTU, the higher the heat output.

 

Each room needs a different BTU to keep it warm depending on the number and type of windows you have and the size of the room. Find out the required BTU for your room using our handy BTU calculator.

 

Once you know your room’s requirements, choose a radiator (or multiple radiators) with the BTU output to match.

Colour

Radiators may be an essential part of your home, but that doesn’t mean they can’t complement each room and its style.

 

Our range of radiators – from central heating to designer – come in white, chrome or anthracite.

 

You can paint radiators with radiator paint or metal paint designed to withstand high temperatures, giving you even more flexibility when designing your space.

Material

The most common material for radiators is steel, which retains heat for a long time even after the radiator is turned off – meaning the room stays toasty for a while.

 

Aluminium designer radiators are also popular because they conduct heat faster, meaning they heat up rooms quickly.

Radiator Valves

Radiator valves are sold separately to give you freedom to choose how you want to control your heating.

 

We stock four types of radiator valves. Thermostatic valves auto-adjust based on the room temperature. Manual valves turn on and off like taps, while dual fuel valves heat a radiator using electricity or hot water. Smart valves allow you to remotely set temperatures and heating schedules for each radiator from your smart device.

Radiator Keys

Radiator keys are an essential accessory for your central heating radiators, and are primarily used to bleed a radiator of excess air to keep it working efficiently.
