Material
Manufactured from durable steel, this towel rail delivers excellent strength and resilience at an affordable price point. Steel is the most popular choice for towel rails due to its wide variety of finishes and reliability in withstanding daily use.
Style
This model features a straight ladder design—horizontal bars run flat between two vertical collectors, creating a clean, space-saving silhouette. Ideal for bathrooms where space is at a premium, the straight profile ensures a sleek, flush finish against the wall.
Colour
Finished in timeless matt black, this towel rail brings bold contrast and modern flair to any bathroom décor. Black works with virtually any colour palette and interior style, from contemporary minimalism to industrial chic. It also hides dust and dirt better than lighter colours, keeping your bathroom looking sharp for longer.
Heat Source
This is a dual fuel radiator, meaning it operates on your central heating system during the colder months and can also run independently via electricity during summer. That means dry, warm towels all year round without needing to heat your entire home.
Accessories
Supplied with everything you need for installation:
Wall mounting brackets and masonry fixings
Chrome bleed valve and blanking plug
Electric element
2 x T-pieces
1 pair of angled manual valves
The T-pieces allow simultaneous installation of the electric element and heating valves. The second T-piece is optional—perfect for those who want symmetrical valve placement. The element can be installed on either the left or right side of the towel rail to suit your setup.
The Element – Talus Standard Element
This simple yet effective electric element allows basic on/off control. Wire it into a switched fused spur or an external timer unit for added flexibility. An ideal choice for those seeking no-fuss, independent electric heating when the central system is off.
Important: The electric heating element must be installed by a registered competent electrician. Incorrect installation will void the product warranty. Fuse size recommendations are based on a 230V UK supply, but your electrician will determine the appropriate fuse based on actual voltage.

Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas or oil boiler with a flow temperature of around 75°C and a return temperature of around 65°C.
- Δ30 = Low temperature systems e.g heat pumps.
