Q.
What makes this a dual fuel towel rail?
A. It connects to your central heating via valves and also has a bottom inlet for a 300W electric element. In winter, your boiler heats it. When the boiler is off — in summer or a mild evening — the element keeps it warm independently.

Q.
Can I use it as electric-only without connecting to central heating?
A. Yes. Isolate the valves and run purely on the electric element. However, if there's no existing pipework, the pre-filled electric-only version is a simpler and neater installation.

Q.
Do I need both a plumber and an electrician?
A. For a full dual fuel setup, yes — a plumber connects the rail to your central heating via valves, and a qualified electrician wires the element to a fused spur. Both are regulatory requirements for bathroom installations in the UK.

Q.
Is the electric element already fitted?
A. No. The element is ordered separately and shipped in the box. Your electrician fits it into the bottom inlet. You only need it if you want the rail to run when your central heating is off.

Q.
What does the glycol pre-fill do?
A. The glycol fluid acts as anti-freeze and anti-corrosion protection when the rail runs in electric mode. It also reduces noise and limescale build-up, helping the rail last longer. The rail is sealed — no top-ups required.

Q.
What are the pipe centres, and how do I check they match?
A. Pipe centres are 150mm — the horizontal distance between your hot and cold pipes at the wall. Measure between your existing pipe centres before buying. For a 200mm wide rail, 150mm is the standard spacing. A T-piece + angled valve combo shifts this by ~70–75mm if your pipes don't line up exactly.

Q.
Why do I close one central heating valve in dual fuel mode?
A. When you heat the rail on its electric element, close one of the two central heating valves. This stops heat escaping back down your central heating pipes, so the element only warms the rail. Either valve is fine — left or right — as long as one stays shut. When the boiler comes back on in autumn, reopen it so hot water can flow through the system again.
