This black Lumaoval measures 1200x400mm and mounts vertically. Round tube bars give towels air on both sides, so they dry faster than they would folded over a flat face. Heat output is 1,750 BTU at ΔT50 — 510W in metric.
Connections are 1/2" BSP and it needs a pair of 15mm valves, sold separately.

Frequently asked questions
Will it fit a narrow wall?
At 400mm across and 1200mm tall it is designed for tall, narrow wall space. Measure 400mm plus a little either side for your hands, and allow about 100mm underneath for the valve tails.
Why are two BTU figures quoted?
Heat output depends on how hot the water is. At ΔT50 this rail gives 1,750 BTU; drop the flow temperature, as a heat pump does, and it falls to about 1,600 BTU. Most UK merchants quote the ΔT50 number.
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 1200x400mm and 1,750 BTU, so there is a smaller and a larger option either side of it.
Are valves included?
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.
