What You'll Learn
Electric towel rails are filled with water
Electric towel rails are an excellent option for areas such as kitchens, bathrooms, and en-suites, providing a stylish and supplementary heat source without causing disruption to structural elements. They are also a great option for those without a central heating system as they are powered by electricity.
Some electric towel rails come with a pre-filled water solution, while others need to be filled manually. When filling a towel rail manually, it is important to follow the manufacturer's instructions carefully. This typically involves using a measuring jug to fill the radiator to the correct level and ensuring that the radiator is properly sealed before use.
It is important to note that electric towel rails should be installed by a qualified electrician to ensure a safe installation that adheres to building regulations. Additionally, regular maintenance, such as bleeding excess air from the radiator, may be required to ensure optimal performance.

They can also be filled with oil
Electric towel rails are typically filled with water, but they can also be filled with oil. Oil-filled electric towel rails have several advantages over their water-filled counterparts. Firstly, oil has a higher heat capacity than water, which means that oil-filled rails can retain heat for longer periods of time, even after being switched off. This makes them more energy-efficient and cost-effective in the long run.
Oil-filled electric towel rails also have a more even heat distribution compared to water-filled ones. While water-filled rails tend to have varying temperatures across the heated region, resulting in "hot spots", oil-filled rails provide a more consistent and uniform heat output. This is due to the higher thermal conductivity of oil, which allows heat to spread more effectively across the surface of the rail.
Another benefit of oil-filled electric towel rails is their slower cooling rate. Oil takes longer to cool down than water, which means that the rail can stay warm for extended periods even after being turned off. This can be particularly useful if you want to conserve energy by turning the rail off temporarily but still want to maintain a comfortable temperature in the room.
In terms of installation and maintenance, oil-filled electric towel rails may have specific requirements that differ from water-filled ones. It is important to carefully follow the manufacturer's instructions for filling and installing the rail, as the process may vary depending on the model and type of oil used. Additionally, oil-filled rails may require periodic refilling or topping up to ensure optimal performance over their lifespan.
It is worth noting that there are different types of oils used in electric towel rails, and the specific type of oil may vary between manufacturers. Some common types include thermal oil, glycol, and corrosion-inhibited oil. Each type of oil may have unique properties and advantages, so it is essential to refer to the product specifications and instructions provided by the manufacturer.

Some come with a pre-filled solution
Electric towel rails are usually filled with water. However, some come with a pre-filled solution, which is often a mix of water and a corrosion inhibitor. These rails are ready to be installed out of the box and simply need to be wired into a power source.
The pre-filled solution in electric towel rails is typically made up of a combination of water and an anti-corrosion inhibitor, which helps to prevent rust and extend the life of the rail. The solution is heated via the rail's heating element, which is connected to the mains electricity supply. This allows the rail to generate heat without relying on a central heating system.
Some electric towel rails, such as those offered by Trade Radiators, come with an accompanying fluid pack that needs to be poured into the rail before use. The fluid is heated by the rail's heating element, causing the rail to give off heat. It is recommended that a qualified professional handle the filling and installation process to ensure safety and compliance with building regulations.
It is important to note that the top bars of electric towel rails may not get as hot as the rest of the rail. This is because the rails are typically filled to only about 90% of their capacity, leaving 10% space for the expansion of the liquid and preventing overpressure. This expansion space is crucial to avoid building up pressure during the first usage.
When installing an electric towel rail, it is connected to the mains electricity supply, and the heating element is activated. The heating element warms up the fluid within the rail, distributing heat around the space. This process allows the rail to provide supplementary heat in areas such as kitchens, bathrooms, and bedrooms.

You can buy 'dry' electric towel rails with no liquid
Electric towel rails are typically filled with water or oil. However, you can also purchase dry electric towel rails that do not contain any liquid. These are powered solely by electricity and have a silicon-sealed wire inside the bars/tubes that heat up the rail.
Dry electric towel rails are easy to install and use. They can be mounted onto a wall and simply wired into a power source, without the need for plumbing or filling with water. The heat output of these rails is typically limited to a maximum of 100 or 150 watts, which is sufficient for drying and warming towels, but may not be powerful enough to heat an entire room.
One advantage of dry electric towel rails is their quick heating time. They heat up faster than liquid-filled rails and can reach higher surface temperatures. However, they may not maintain a constant temperature as effectively, as liquid-filled rails warm up and cool down more slowly and produce a more even heat.
When choosing between a dry electric towel rail and a liquid-filled option, consider your specific needs and the other sources of heat in your space. If you require a rail that can also heat the room, a higher-wattage liquid-filled option may be preferable. However, if you already have another heat source and primarily need a rail for drying and warming towels, a dry electric towel rail could be a suitable choice.
Overall, dry electric towel rails offer convenience and simplicity, providing a quick and effective way to warm your towels without the need for any liquids or complex installation processes.

The liquid is heated via the mains electricity supply
Electric towel rails are filled with a mixture of water and anti-corrosion inhibitor, which is heated via the mains electricity supply. The anti-corrosion inhibitor accounts for about 15% of the mixture, while water makes up the remaining 85%. This liquid mixture is what allows electric towel rails to operate without a central heating system.
The process of heating the liquid is facilitated by an electric heating element, which can be either single non-thermostatic or variable thermostatic. Single non-thermostatic heating elements enable the towel rail to maintain a constant temperature when switched on, while variable thermostatic components allow users to adjust the temperature.
To fill an electric towel rail, the radiator is first affixed to the wall using brackets. A trained electrician then completes the wiring, connecting the towel rail to the mains electricity supply. Once the wiring is complete, the heating element is turned on and the liquid inside the radiator is heated. It is important to ensure that the radiator is not sealed until the liquid is fully heated, as this can cause pressure to build up during the first usage.
Some electric towel rails come with accompanying fluid packs that need to be poured into the rail before use. These fluid packs contain a solution that heats up and causes the rail to give off heat. It is recommended that a qualified professional handle the filling and installation process to ensure safety and adherence to building regulations.

Frequently asked questions
Electric towel rails are filled with a mixture of water and anti-corrosion inhibitor. The inhibitor prevents rust and accounts for about 15% of the mixture, while water makes up the remaining 85%.
It depends on the type of electric towel rail you have. If you have a "dry" electric towel rail, you do not need to fill it with water or any other liquid. However, if you have a "wet" electric towel rail, you will need to fill it with water before use.
First, assemble the radiator, element, and vent plugs, leaving one of the four holes in the radiator open. Then, use a measuring jug to fill the radiator completely with water to find its total capacity. Drain the water and refill it to 90% capacity with a mixture of water and radiator/corrosion inhibitor. Leave the remaining 10% as air to allow for water expansion. Finally, screw the plug into the fourth hole to seal the radiator.
Dry electric towel rails do not require water and can be wired directly to a power source. Wet electric towel rails, on the other hand, need to be filled with water before use and are connected to a central heating system.
