The Arvani 1200x600mm is a vertical anthracite towel rail built to warm a larger family bathroom and dry towels at the same time. Heat output is 2,396 BTU at ΔT50 — 703W 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 600mm across and 1200mm tall it is designed for tall, narrow wall space. Measure 600mm 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 2,396 BTU; drop the flow temperature, as a heat pump does, and it falls to about 1,800 BTU. Most UK merchants quote the ΔT50 number.
How does it compare with the other Arvani sizes?
This is the largest Arvani, at 1200x600mm and 2,396 BTU. The range starts at 650x450mm (1,060 BTU), so there are smaller options if the wall will not take this one.
Which radiator valves go with it?
Valves are separate. Angled where your pipes come out of the wall, straight where they come up from the floor. The connections are 1/2" BSP and take a standard pair of 15mm valves — in anthracite if you want them to disappear against the rail.

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.
