Sulby
Dry heat, stainless steel, black
A stainless steel dry electric towel rail with a precision thermostat, 7 day programmer and WiFi app control built in. No liquid fill, no leaks, no hours-long wait for a cold rail to catch up. A matte black powder finish over the same stainless steel body. Matte black hides handling marks and water spots far better than a polished surface, and reads as a bold, contemporary fixture rather than a background fitting.

Wall to warm towel, three steps.
Step 01
Mount
Wall brackets and decorative caps are supplied. Fitting is by a qualified electrician, with 600 mm minimum clearance from the floor.
Step 02
Wire
Concealed or exposed wiring, routed to the left or right side of the rail to suit the bathroom.
Step 03
Connect
Pair the rail to the SolAire WiFi IQ app, or leave it running from the onboard thermostat and timer.
Dry thermal technology
No filling. No fuss.
The Sulby uses a dry thermal element rather than liquid-filled tubes, so the whole rail heats evenly instead of running cool at the bottom the way large fluid-filled rails can on a cold morning. It is lighter to hang, faster to heat, and carries no risk of leaks, bleeding or internal corrosion to maintain.

LST
Low Surface Temperature mode caps the rail at 43°C for child-safe rooms and assisted living spaces.
04
Instant adjustment

WiFi app
Control it from wherever you are.
Connect the rail to the SolAire WiFi IQ app, on iOS or Android, and adjust temperature, modes and timers remotely, check whether it is online, and manage several rails from one account. Amazon Alexa and Google Home are both supported for voice control.

Safety
Child lock and a low surface temperature mode.
Lock the control panel to stop accidental changes, or switch to LST mode to cap the surface at 43°C for a child-safe bathroom or an assisted living space. Must be installed by a qualified electrician, with 600 mm minimum clearance from the floor.
