Energy efficient. Stylish heating.

The Onsen is the perfect electric bathroom heater. With Radialight’s Dual-Therm technology, the Onsen uses a combination of radiant and convection heating to warm your bathroom. Tests by the manufacturer show that it can dry towels up to 40% faster than classic towel rails. at 750W power output, it can heat rooms up to 9m2 in size or be used as an additional room heater for larger spaces.

The fan-assisted convection rapidly spreads heat across the bathroom. Additionally, a second element radiates heat outwards from the surface, in a similar fashion to a conventional radiator. This creates a comforting warmth you can feel on your skin and use to dry items with.

The two bars supplied with the heater can be fitted to the front for drying towels and other items.

With a 24/7 timer and built-in thermostat, the Onsen electric bathroom heater can be programmed based on your needs. You will never have to walk into a cold bathroom again.

Other features include open window detection, program modes (automatic, manual, frost free) and a boost function for (providing maximum power for 60, 90 or 120 minutes duration).

The heater is IP24-rated making it splash proof and suitable for bathroom zone 1 and above.

With a 2 year guarantee covering all of this, you can be reassured that the Radialight Onsen won’t let you down.
