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
- QUADRUS SLIM is designed with a single-layer bar configuration.
- The flat bars and closely spaced gaps create a distinctive, fuller appearance compared to standard ladder rails.
- The front bars protrude from the uprights, providing a generous space for easily hanging towels.
- 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 4 different sizes of QUADRUS SLIM 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.

colour & finish

- This is a premium wet paint which is painted using a hand finished liquid paint (as opposed to an automated powder paint), creating a deeper, more metallic type finish.
- Note: If you don't have the budget for a premium wet paint, the closest colour match in a powder paint would be the Halo colour, slightly darker gold. Call us to request this option.
- A 150?ó50mm colour chip of this finish is available to purchase for preview.
- Additionally, we have created a detailed technical guide on paint finishes and colours, giving even more information and tips.

- Element and Valve: 2-year manufacturer.
- Usual lifespan of a heating element is 4 to 7 years dependent on use.
