Your Complete Guide to Towel Radiators & Heated Towel Rails

Towel radiators, also popularly known as heated towel rails, are a brilliant solution that merges comfort with elegance in bathrooms. Not only do they keep your towels toasty and dry, but they also add a touch of luxury and modernity to your space. Understanding the nuances of these fixtures can help you make informed choices. Let's explore the answers to some frequently asked questions that will shed light on the essentials of towel radiators and heated towel rails.

What Exactly Is a Towel Radiator / Heated Towel Rail?

At its core, a towel radiator is a specially designed radiator that serves a dual purpose. It effectively dries towels and garments while simultaneously heating your bathroom. A heated towel rail blends into your bathroom's aesthetic with sleek design choices, ensuring it stands out as an element of décor just as much as a functional appliance.

The Same By Any Other Name: Towel Radiator vs. Heated Towel Rail

The terms towel radiator and heated towel rail are interchangeable. The choice of term typically varies regionally but refers to the same product. Whether you call it a towel radiator or a heated towel rail, both aim to deliver dry, warm towels and a cozy bathroom environment.

Choosing Your Material: What Are Towel Radiators Made Of?

Towel radiators are constructed from various materials, including mild steel, aluminium, and stainless steel, to ensure durability and provide flexibility in design. These materials are also chosen for their excellent heat conductivity and resistance to corrosion, guaranteeing a long-lasting and high-performing radiator.

The Gleam of Chrome: Are Chrome Towel Radiators Really Made of Chrome?

Not exactly. Chrome towel radiators are typically crafted from steel and then plated with chrome for that stunning finish. Beneath the chrome, layers such as copper might be added to enhance the radiator's longevity and resistance to wear.

From Ordinary to Extraordinary: Replacing Your Radiator with a Towel Radiator

Yes, you can replace a standard radiator with a towel radiator to bring function and flair to your bathroom. However, the distance between your existing pipe centres is a vital consideration to ensure compatibility. Kindly refer to this comprehensive guide for selecting the appropriate replacement size for your towel radiator.

The Significance of Pipe Centre Distance

Aligning the new towel radiator's pipe centres with your existing central heating pipes is crucial for a hassle-free installation, mainly if the pipes are floor- or wall-mounted. This matching eliminates the need for pipe adjustments, saving time and money during the installation process.

BTU: Measuring Heat Output

The British Thermal Unit (BTU) is a traditional measure of heat energy, and it's what we use to determine how much heat a radiator can emit. The BTU indicates the power required to raise the temperature of one pound of water by one degree Fahrenheit.

Judging Your Heat Requirements

To estimate how much heat you need from your radiator, consider the heat loss of the space. Our BTU calculator allows you to calculate the necessary heat output to maintain a comfortable temperature in your bathroom. Please check our BTU calculator for your room.


Making the Most of Your Towel Radiator

Towel radiators offer versatility in use. They can be connected to your central heating system, used as electric-only with a heating element, or run as dual-fuel, allowing you to switch between central heating and electric power.

Essentials for a Central Heating Connection

For those connecting a towel radiator solely to the central heating system, all you'll need is a pair of radiator valves. The inclusion of Thermostatic Radiator Valves (TRVs) grants additional control over the temperature of individual rooms.

How to Connect to Your Central Heating

Towel radiators seamlessly integrate with your central heating system through the in-flow and out-flow pipes, which are regulated by the use of valves for optimal performance.

Choosing the Right Valves

Selecting the proper valves depends on your pipework orientation. Straight valves work best with floor pipes, while angled or corner valves are suitable for wall-mounted pipes, ensuring a neat and efficient connection.

Going Electric-Only: What You Need

For those opting for an electrically powered configuration, the essentials include a heating element and a blanking plug, alongside a mixture of water and ethylene glycol to conduct heat efficiently within the towel radiator.

Selecting the Correct Electric Element

Choosing the right wattage for your electric element is crucial for achieving the desired heat output. Our radiators are often paired with the appropriately pre-selected element to take the guesswork out of the process for you. 

The Flexibility of Dual Fuel

Dual fuel towel radiators offer the ultimate in flexibility, letting you utilize the central heating when the house heating is on or switch to electric during warmer seasons. This combination ensures access to warm towels year-round, irrespective of the central heating status.

Parts Required for Dual-Fuel Towel Radiators

Going dual-fuel means having a tee piece to accommodate both heat sources, the right valves for your pipe orientation, and an electric element. The central heating system will take care of the filling medium.

Why is it necessary to close one valve on a Dual Fuel Towel Radiator during the summer?

During summer, if you wish to utilize the electric heating feature of your dual fuel towel radiator, closing one valve is recommended. This procedure halts the flow of heat through the central heating (CH) pipes, ensuring that heat is conserved within the radiator for towel warming without affecting the overall temperature of your home.

Zoning In on Safety: Understanding Bathroom Zones

Bathroom zones are designated for electrical safety to minimize the risks associated with water and electricity. These zones outline where it's safe to install electrical fixtures like towel radiators, ensuring compliance with safety regulations.


Whether you're a seasoned DIY enthusiast or simply looking to upgrade your bathroom's comfort level, understanding the ABCs of towel radiators is crucial for making the right choices. With technology and design constantly evolving, it's more important than ever to stay informed and select products that best fit your needs and lifestyle.
