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
- DIAMOND features diamond shaped bars.
- This model is ideal for family bathrooms or utility rooms thanks to its multiple wide-spaced gaps, providing generous room for hanging both 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 12 different sizes of DIAMOND 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.
the heating element
- The Terma DRY element has one preset heat setting of 48 °C, regulating the internal radiator temperature.
- Ideal for hotels or commercial environments - or energy conscious households, as the DRY will auto shut off after 1, 2, 3, 4, or 5 hours.
...element specifics
- 66 mm length measured from the thread down, with a 55 mm diameter clock-style face.
- Internal probe lengths vary depending on the selected wattage — refer to the diagram in the image gallery.
- Straight cable supplied, no plug.
- IPx5 rated, suitable for use in bathroom environments.
- Class 1 electrical rating.
...controls & operation
- Operation is controlled via two buttons.
...standard option vs. masking option
- You can choose to buy this element with or without the masking cover on the rear.
- The masking cover conceals the wire up to the entry point into the wall, providing a neater, tidier appearance.
- Important note: Masking requires the wall to be trowelled out; if walls or tiles are already finished, the standard (non-masking) option is recommended.
- The cable housing unit can be cut down for radiators that sit closer to the wall than the standard depth (65mm to back of element).
- Ideal for installations where a flush-to-wall appearance is desired.
- Cannot be extended for deeper wall projections.
...straight cable vs. spiral cable
- If your electric supply is very close to the towel rail the spiral cable option will keep the cable tight and coiled.
- See the demo image in the gallery above to see the straight vs. spiral comparison.
- Note:The spiral cable will come pre fitted with a European style plug on the end. This simply needs to be cut off by your electrician to install in a UK bathroom/kitchen and connected to a switched fuser spur.
