Tessa is an asymmetric designer towel radiator that can be installed left or right handed. An anthracite grey finish adds depth and hides the odd mark far better than gloss white.
2 sizes are available, with heat outputs from 1,397 to 2,111 BTU/hr at ΔT60. It is supplied with everything needed to fix it to the wall. It runs on your central heating; valves are sold separately.

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.
