A vertical chrome ladder rail at 1000x500mm, the Lumaoval uses 22mm round tube — the classic towel rail shape, and the easiest to hang a bath sheet over. Heat output is 1,700 BTU at ΔT50 — 500W in metric.
It takes standard 1/2" connections and a pair of 15mm radiator valves, which are ordered separately.

Frequently asked questions
Will it fit a narrow wall?
It is 500mm wide, so it will go where a conventional radiator will not — between a door and a basin, or on the short return wall of an en-suite. Leave roughly 30mm behind it for the brackets and another 100mm below for the valves.
Why are two BTU figures quoted?
1,700 BTU is the output at ΔT50, the standard UK rating. 1,550 BTU is the same rail at ΔT30, which is closer to what you get on a heat pump or a condensing boiler running a low flow temperature. Size from the figure that matches your system.
How does it compare with the other Lumaoval sizes?
The Lumaoval range runs from 800x400mm at 1,200 BTU to 1600x600mm at 2,700 BTU, in 25 sizes. This one is 1000x500mm and 1,700 BTU, so there is a smaller and a larger option either side of it.
Which radiator valves go with it?
No, they are ordered separately. Pick angled valves for pipework coming through the wall and straight valves for pipes from the floor. A thermostatic pair lets you run this rail independently of the rest of the house.

Help choosing
A towel rail should keep the bathroom warm, not just dry towels. Check it's powerful enough for the room.
Enter your room size to see the heat output you need.
- Match the output to the room. Use the BTU figure from the calculator. In a bathroom, a towel rail alone often heats a small room; bigger rooms may need a radiator too.
- Check your connections. Measure the gap between your pipes and choose valves to suit: angled, straight or corner (see the valve helper on our valve pages).
- Heat pump? At the lower water temperatures heat pumps run at, expect roughly half the listed output.
- Summer use. Central heating rails only warm up when the heating is on. A dual fuel kit adds an electric element where the rail supports it.
Still not sure? Send us your measurements and we'll check for you.
