Energy efficient. Stylish heating.

The Onsen is the perfect bathroom heater. With Dual-Therm technology, the Onsen uses a combination of radiant and convection to heat your bathroom. 

The Fan assisted convection spreads heat across the bathroom which warms the room very quickly. 

Additionally, a second element radiates heat from the front of the heater. In a similar fashion to a conventional radiator. This heat creates a comforting warmth you can feel on your skin and use to dry items with. 

The two towel bars supplied with the heater can be fitted to the front. This will let you towels and other items.

With a 24/7 timer and thermostat inbuilt, the heater can be programmed based on your needs. So you never have to walk into a cold bathroom again. 

Also included is: open window detection, and a boost function for 60, 90 or 120 minutes.

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 the Onsen won’t let you down.
