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
- ZIG ZAG makes a striking first impression and brings positive, uplifting energy to any interior.
- Its distinctive shape, everyday functionality and wide choice of colours make it an ideal option for creating a truly individual bathroom design.
- A genuine Terma original, ZIG ZAG features horizontal bars set at an angle, allowing towels to be placed easily over the top bar.
- The chunky square-profile bars pair perfectly with modern, linear bathroom accessories.
- With brackets positioned on the uprights, the main design area remains clean and unobstructed.
- ZIG ZAG works best as a bathroom focal point, adding a bold and contemporary designer touch.
- Made from low carbon mild steel.
the specialist dual fuel valve
- The TWINS valves and pipe masking set from Terma comprise:
- 50mm integrated thermostatic valve body and head
- 2x 50mm length pipes
- 1x wall masking cover with 2 holes
- Made from coloured plastic, brass, and steel for durability and strength.
the heating element
- The KTX 4 BLUE is a detachable controller which powers the TS1 probe (sold separately), forming a complete and reliable heating element and allowing easy maintenance and replacement of the probe without removing the entire unit.

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.
- Masking length varies between 52mm and 65mm according to technical drawings.
- The control head adds 42mm depth in front of the masking.
- This means the radiator’s “wall to centre of inlet” figure must be between 93mm (52+41) and 108mm (66+41) for the masking cover to fit.
- If the entry point is deeper than this range, the masking cover cannot be fitted.
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 images to see the straight vs. spiral.
- As this item is made to order you can configure it exactly as you'd like it to be made for you.
colour & finish
- Heated Towel Rail is Painted in Brass (premium wet paint).
- Finished in a metallic, smooth texture.
- This is a premium wet paint, applied using a hand-finished liquid process (as opposed to an automated powder paint). This creates a deeper, more metallic finish.
- Note: If you don't have the budget for a premium wet paint, the closest colour match in powder paint would be Halo — slightly darker gold, not quite brass — costing approximately 25% less than the premium option. Please call us to request this colour, as it is not listed in Halo on our website yet.
- The element is chrome with a grey cable.
safety & compliance
- Fully built and tested to EN442 standards and UKCA certified.
- Heat outputs are independently verified by an external testing house to ensure accuracy.
guarantee & warranty
- Rail: 12-year manufacturer’s warranty for long-term reassurance.
- Element and Valve: 2-year manufacturer’s warranty.
- Usual lifespan of a heating element is 4 to 7 years depending on use.
- At end of life, you can simply replace the heating probe (TS1) part of this element while the controller can continue to be used, making it a cost-effective long-term solution.
