what is a dual fuel towel rail?
- Dual fuel means you can run the same towel rail in two ways — as electric via the use of a heating element in the summer (when you may only want to dry your towels or clothes) and as central heating in the winter (when the full system is on).
- The water inside the towel rail comes from your central heating system as normal — when the main system is off this water will sit idle, and in the summer the element installed in the towel rail will warm the water located inside just this towel rail. You can keep both of the valves open.

the heated towel rail
- LIMA features periodic projected C-shaped bars against a rear layer of flat bars for easy towel hanging.
- The design is distinctive compared to standard chrome ladder rails, making it a sought-after choice for those wanting a more designer look and feel.
- Ideal for family bathrooms or utility rooms, with multiple gaps for hanging towels and clothes.
- Made from low carbon mild steel.
...full range of sizes available
- In addition to the sizes we are displaying here on the heat is on - you can view the full range of 50+ different sizes of LIMA here on the Terma website.
- When viewing the Terma website, the heat outputs are only listed in Watts - using the column header stating 75/65/20, multiply the amounts by 3.41 to get the BTUs equivalent.
- If you want to learn more about heat output, view our technical guide on heat output.
- We can process a special order for any size you wish to purchase if that size is not shown on our website.
the specialist dual fuel valve
- This specialist dual fuel valve is the best valve to for a dual fuel towel rail as the flow/return is located on the same side of the radiator — leaving the opposing side free for the heating element (so no T-Piece is required, unlike a standard dual fuel set-up).
- The flow and return travel through the valve via the immersion tube: flow goes up the tube and the return comes back down the outside of the tube.
- Angled orientation.
- Choose left or right side as you need for your specific installation - see the image which shows both orientations show side by side to see which suits your room setup and pipework setup best.
