Radiant Timers and Thermostats

Radiant timers and thermostats are control units that let you schedule or automatically regulate a heated towel rail or bathroom heater rather than leaving it running continuously or having to switch it on and off manually. Made by Radiant, this range of 15 controllers gives a straightforward way to add scheduling and temperature control to existing bathroom heating.

Why add a timer or thermostat to your heating

Bathroom heating, particularly heated towel rails, is often left switched on far longer than needed simply because it is inconvenient to keep manually turning it off. A timer solves this by automatically switching the unit off after a set period, while a thermostat regulates heating based on temperature rather than a fixed schedule. Both approaches reduce unnecessary running time, which can help lower energy use compared with heating left on around the clock, and add genuine everyday convenience since you are no longer relying on remembering to turn things off.

Timers

A timer control allows you to set your towel rail or heater to run for a defined period, such as first thing in the morning or in the lead up to an evening shower, then switch off automatically. This suits households with fairly predictable routines, where heating is really only needed at specific times of day.

Thermostats

A thermostat control instead monitors temperature and cycles the heating on and off to maintain a set level, which suits rails or heaters that are used more for ongoing bathroom warmth rather than purely for drying towels. This can offer more consistent comfort than a simple timer, particularly in cooler months.

Compatibility with existing heating

Radiant's timers and thermostats are designed to work with heated towel rails and similar bathroom heating units, making them a practical add on or upgrade rather than requiring a full heater replacement. Because there are 15 different controllers in the range, it is worth checking compatibility with your specific towel rail or heater model, along with the wiring and mounting requirements, before purchasing.

Choosing the right control for your bathroom

If your routine is predictable and heating is only needed at set times, a timer is generally the simpler and more cost effective option. If you want the bathroom to maintain a consistent temperature without thinking about it, a thermostat is the better fit. Either way, confirm compatibility with your existing heated towel rail or heater and have installation checked by a licensed electrician given the fixed wiring involved.
