Frequently Asked Questions
How do I calculate the correct British Thermal Unit or BTU output required for my specific bathroom size to ensure it stays warm?
To get the right heat you need to measure the height width and length of your bathroom in metres. Put these numbers into a BTU calculator found on our site. If your bathroom has big windows or outside walls you will need a higher BTU number. A heated towel rail with a low BTU might only warm your towels so always match the BTU number to your room size for full heating.
What is the technical difference between a dual fuel heated towel rail and a standard central heating version and how does the T-piece work?
A standard rail only works when your central heating boiler is on. A dual fuel rail connects to your pipes but also has an electric heating element inside. The T-piece is a special connector that lets the electric element and the water pipes enter the rail at the same spot. This allows you to switch to electricity in summer when the main boiler is turned off so you still have dry towels.
Why do chrome plated heated towel rails have a lower heat output compared to white or painted finishes and does this affect drying time?
Chrome is a shiny metal that acts like a mirror for heat. It traps some of the heat inside the metal rails instead of letting it radiate out into the air. This means a chrome rail might give out about 20 to 30 percent less heat than a white one of the same size. It will still dry towels perfectly fine but it might take a little longer to heat up the whole room.
Which type of radiator valves do I need to buy if my water pipes are coming up from the floor versus coming out of the wall?
If your pipes come up from the floor you need Straight Valves because the water flows straight up into the bottom of the rail. If your pipes come out of the wall you usually need Angled Valves or Corner Valves. Angled valves allow the connection to turn 90 degrees so the pipe joins the rail neatly without bending the pipework.
What is the importance of the IP rating for an electric heated towel rail installation in a bathroom Zone 1 or Zone 2 area?
IP stands for Ingress Protection and it rates how safe the item is against water. In a bathroom safety is critical. For Zone 1 and 2 which are close to the bath or shower you typically need an IP44 rating or higher. This rating proves that the electric parts are sealed against water splashes so you do not get an electric shock.
How do I fix a heated towel rail that is hot at the bottom but stays cold at the top even when the heating is on full power?
This problem is caused by air bubbles trapped inside the top of the rail. Air rises above water and stops the hot water from reaching the top bars. To fix this turn off your heating and find the bleed valve at the top. Use a radiator key to open it slightly until you hear hissing. Close it tightly as soon as water starts to come out.
Can I install a thermostatic heating element into my towel rail to control the temperature and save on electricity costs?
Yes you can install a thermostatic element. A standard element is just on or off but a thermostatic one lets you pick a temperature. It senses when the rail is hot enough and turns the power off automatically. This stops the rail from getting too hot to touch and saves you money on your energy bill by not wasting electricity.
What is the distance between pipe centres and why is this measurement critical before purchasing a replacement towel rail?
The pipe centres measurement is the distance between the centre of the left pipe input and the centre of the right pipe input. You must measure this exactly on your existing pipes before buying a new rail. If you buy a rail with different pipe centres it will not fit your pipes and you will have to pay a plumber to dig up your floor and move the pipes.
Is stainless steel a better material choice than mild steel for preventing rust and corrosion in a damp bathroom environment?
Stainless steel is generally better than mild steel for stopping rust. It is a premium metal that does not corrode easily even in wet bathrooms. Mild steel is cheaper and works well if the chrome plating is high quality but stainless steel lasts longer. If you want a rail that stays looking new for decades stainless steel is the superior technical choice.
How does a thermostatic radiator valve or TRV function to regulate the heat output of a central heating towel rail?
A TRV has a sensor inside the head that detects the air temperature in the room. If the room gets warm enough the valve closes slightly to reduce hot water flow. If the room gets cold it opens up to let more hot water in. This helps maintain a steady temperature automatically rather than just making the rail super hot all the time.
What is the difference between a liquid filled electric towel rail and a dry element rail in terms of heating speed and retention?
A liquid filled rail contains a fluid usually a mix of water and glycol which is heated by an element. It takes longer to heat up but stays warm for a long time after you turn it off. A dry element rail has a wire inside like a toaster. It heats up very fast but cools down immediately when turned off. Liquid filled is usually better for drying thick towels effectively.
How much weight can a wall mounted heated towel rail hold and do I need special fixings for plasterboard walls?
A large towel rail filled with water and wet towels can be very heavy. Standard plasterboard might not hold it securely. You should try to screw the brackets into the wooden studs behind the plasterboard. If you cannot find studs you must use heavy duty plasterboard fixings or toggle bolts to ensure the rail does not pull away from the wall and cause a leak.
Why do I need to add a rust inhibitor chemical to the water system when installing a new heated towel rail?
When fresh water enters your heating system it brings oxygen which causes steel to rust from the inside out. This creates black sludge that blocks your boiler. A rust inhibitor is a chemical liquid you pour into the system. It coats the inside of the metal pipes and rail to stop corrosion. It is essential for protecting your warranty and boiler health.
Can I use a heated towel rail as the only source of heating in a large family bathroom or do I need a secondary radiator?
This depends strictly on the BTU output. Many towel rails have gaps between the bars so they have less surface area than a panel radiator. If your bathroom is large a single rail might not provide enough heat in winter. You should calculate the room heat requirement first. Often a secondary radiator or underfloor heating is needed alongside the rail for large rooms.
What are the electrical safety requirements for the fused spur connection when installing an electric towel warmer?
An electric towel warmer must not be plugged into a normal socket inside a bathroom. It must be wired into a fused spur outlet. This is a special box on the wall that protects the circuit. This fused spur is usually placed outside the bathroom or in a safe zone inside. It allows you to isolate the power safely if maintenance is needed.
How does the projection measurement affect the installation of a towel rail in a small or narrow cloakroom space?
Projection is how far the rail sticks out from the wall. In a tiny cloakroom or behind a door a rail with a large projection might block movement or stop the door from opening. You should check the technical drawing for the projection number. Curved rails usually stick out further than flat rails so a flat rail is the best technical solution for tight spaces.
Is it possible to convert a standard central heating towel rail into an electric only version using a filling kit?
Yes you can convert almost any standard rail into electric only. You need to buy an electric heating element and a filling kit. You fill the rail with water and inhibitor fluid leaving a small air gap for expansion at the top. You then screw the element into the bottom and seal it tight. This creates a standalone heater that does not need plumbing pipes.
Why is there a pressure safety limit for heated towel rails and is it compatible with a high pressure combi boiler system?
Every radiator is tested to withstand a certain water pressure usually measured in bars. Combi boilers operate at high pressure. If you buy a very cheap or low quality rail the high pressure could cause the welds to crack and leak. Our rails are pressure tested to ensure they are fully compatible with modern high pressure combi boiler systems in the UK.
What does the Delta T50 measurement mean on the technical specifications and how does it relate to the actual heat output?
Delta T50 is the standard European condition for testing radiator heat. It assumes the water in the radiator is 75 degrees and the room is 20 degrees. If your boiler runs cooler than this the actual heat output will be lower than stated. It is a technical benchmark to help you compare the power of different rails accurately before you buy.
How do I clean and maintain the surface of a black or anthracite powder coated towel rail without damaging the finish?
Powder coated finishes like black or anthracite are durable but can be scratched by abrasive scourers. To clean them technically you should use a soft microfibre cloth and warm soapy water only. Do not use acidic cleaners or bleach as this can strip the paint and lead to rust. Regular dusting keeps the heat output high by allowing air to flow freely.
