Controllers and Thermostats

Heating Controllers and Thermostats Buying Guide

A heated towel rail left running around the clock is one of the more common sources of unnecessary energy use in a bathroom, largely because switching it off manually every time is easy to forget. A dedicated controller removes that reliance on memory, automating the rail's operation instead.

Touchscreen timers

This collection includes genuine 7-day touchscreen timers, letting a heated towel rail's schedule be set to match the household's actual routine rather than running continuously. The Thermogroup TRTS touch screen timer gives a straightforward portrait-format control, while the Thermogroup TRTSL offers the same 7-day scheduling in a landscape orientation, worth considering depending on the available wall space and mounting position. The Radiant Digital Touchscreen Timer Switch offers a similarly considered, current interface for the same core function.

Why a timer or thermostat is worth adding

A timer lets the rail run for a defined period, first thing in the morning or ahead of an evening shower, then switch off automatically, suiting a household with a fairly predictable routine. A thermostat instead monitors temperature and cycles the heating on and off to maintain a set level, better suited to a rail used for genuine ongoing bathroom warmth rather than purely for drying towels. Both approaches reduce unnecessary running time compared with a rail left on constantly, offering a genuine, practical saving on energy use over time.

Choosing a finish

This collection spans black, chrome and white, letting the controller be matched to the room's existing switches, tapware or towel rail finish rather than standing out as a mismatched addition.

Installation

A controller or thermostat involves genuine electrical work, and given the fixed wiring involved, installation should always be carried out by a licensed electrician, both for safety and to ensure the unit is correctly matched to the specific towel rail being controlled.

Completing the bathroom

A controller or thermostat is easiest to choose once the existing heated towel rail model is confirmed, since compatibility depends directly on that fixture. The Blue Space's Heated Towel Rails collection is worth reviewing alongside a controller selection to plan the full heating setup together.
