what is a dual fuel towel rail?

  • Dual fuel means you can run the same towel rail in two ways ‚Äî 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 ‚Äî 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.
  • If you want to learn more about dual fuel, read our dedicated dual fuel towel rail guide here.

the heated towel rail

  • GRID has been designed in response to the industry demand for a minimalist, framed form with a flat profile.
  • The flush surface and clean lines make it ideal for modern interiors inspired by Scandinavian design.
  • Its seamless frame has no lips and features gentle radius corners, creating a sleek, contemporary towel rail aesthetic.
  • Can also be paired with wooden shelves to add a functional and stylish storage element.
  • Note: Shelves are not included in the price and these need to be bought separately.
  • 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 9 different sizes of GRID 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.

  • Thermostatic operation for precise temperature control.
  • Non bi-directional valves; ensure correct orientation is selected - left or right sided — please refer to the key on the images to identify the correct flow (hot water in) and return (cooler water out) sides and remember to take into account if you have side or underside entry.
  • Supplied as a complete installation kit — no need for additional fittings.
  • Includes 50mm pipe masking set for a clean wall connection.
  • Compatible with both copper and multilayer pipe systems.
  • NOTE: You will discard the TRV Head supplied with these valves and replace it with the VAZ TRV Head described below.

  • 5-segment LED indicator shows the currently set temperature and signals active functions, with a fading backlit display for subtle aesthetics.
  • Control panel adapts to the installation position of the head (vertical or horizontal).
  • Powered by a high-performance Lithium 6700 mAh (24.12Wh) battery, capable of lasting an entire heating season on a single charge depending on operating mode.
  • IPx4 rated, Class 3, UKCA Approved.

the heating element

  • The VEO is a Wi-Fi enabled controller which powers the SMART Split probe, forming a complete and reliable heating element.
  • Basic control (temperature and a simple timer) is available directly from the front panel.
  • Full advanced functionality is available through the Terma SMART app (iOS/Android) for full control and flexibility.
  • Offers 5 room temperature settings from 15¬?C to 28¬?C.
  • Includes a drying function and a full 7-day timer.
  • Compatible with Amazon Alexa, Google Assistant, and IFTTT for voice and smart-home integration.
  • No additional hub is required.

...element specifics

  • Compact dimensions: 75.6mm length from thread down, 70.5mm width.
  • Supplied with a straight cable and fitted UK 3-pin plug (remove if used in a bathroom).
  • IPx5 rated, safe for use in bathroom environments.
  • Class 1 device meeting electrical safety requirements.
  • UKCA approved for compliance with UK regulations.

...precision options for the element

  • Can be paired with the VTS wall-mounted temperature sensor and the VOS open window sensor (both sold separately) for precise room-wide temperature measurement.
  • Provides optimal comfort and energy efficiency by adjusting heating based on room conditions.
  • Features geo-location functionality, reducing temperature by 3‚Äì4¬?C when leaving home and returning to comfort mode when you arrive.

...standard versus cable masking

  • The masking option 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.

...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.

colour & finish

  • Heated Towel Rail is Painted in Red Wine (premium wet paint).
  • Finished in a matt, smooth texture.
  • This is a premium wet paint which is painted using a hand finished liquid paint (as opposed to an automated powder paint - so this paint is more expensive). This creates a deeper more metallic type finish.
  • A 150?ó50mm colour chip of this finish is available to purchase for preview (link to colour chip will be on right-hand side of page).
  • The element is in a matching red wine colour with a black fascia and black 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.
  • Usual lifespan of a heating element is 4 to 7 years dependent on use.
  • At end of life, you can simply replace the SS1 heating probe inside this model, as the external VEO controller is a separate unit — making replacement a cost-effective and straightforward process.
