Here at the heat is on, we put the knowledge of what you need directly in your hands as the homeowner, so you needn’t ask or wait for information from your electrician. Here we give you complete expert guidance for this specific electric towel rail — including details of any additional parts required — so you can ensure a smooth and successful installation when your tradesman arrives.
heat output
- Firstly, if you haven't already done so - use our heat calculator to work out your specific requirements for your room to ensure you are looking at the right size electric radiator - in terms of the Watts / Kilowatts heat output it gives.
design & material
- WARP T BOLD is designed with double-layered bars at the front and rear, offering very high heat outputs and giving you the option to hang your towel on either layer.
- The front layer of bars has a delicate curve at either end, while the rear layer is completely flat and suspended between the two uprights.
- WARP T BOLD is very stylish in its construction, with neat rectangular uprights that complement the flat rectangular shape of the bars.
- WARP T BOLD has a much larger surface area compared to many standard ladder-type rails — so the colour stands out far more as a feature in the bathroom.
- Made from low carbon mild steel.
- Additionally, we have created a thorough and detailed technical guide on electric radiators, giving even more information and tips.
