Arvani 650x450mm Black Heated Towel Rail – Flat Panel, Vertical Mount, Matt Finish

Arvani in black is a flat panel towel rail rather than a ladder, so towels hang against a solid warm face. At 650x450mm it suits a cloakroom or a compact en-suite. Heat output is 1,060 BTU at ΔT50 — 311W in metric.

Plumbing is standard: 1/2" inlets and outlets, plus a pair of 15mm valves.

Frequently asked questions

Will it fit a narrow wall?

Yes — 450mm is narrow enough for most awkward walls. The height is where it takes its space: 650mm, so check you have headroom above the skirting and below any shelf or cabinet.

Do I still need a radiator as well?

1,060 BTU covers a room of roughly 3.5m². Measure your bathroom and run the figure through a BTU calculator — if it comes back higher than 1,060, go up a size or add a second heat source.

Why are two BTU figures quoted?

Heat output depends on how hot the water is. At ΔT50 this rail gives 1,060 BTU; drop the flow temperature, as a heat pump does, and it falls to about 818 BTU. Most UK merchants quote the ΔT50 number.

How does it compare with the other Arvani sizes?

Arvani comes in 10 sizes, from 650x450mm at 1,060 BTU up to 1200x600mm at 2,487 BTU. This is the smallest of them, so if 1,060 BTU is short for your room there is plenty of headroom above it.
