Instruction Manual
Looking for a heater that delivers serious warmth without eating up floor space? The 1.5kW Theia Infrared Bar Heater does exactly that—and it looks good doing it.
It uses near infrared to warm people, objects, and surfaces directly whilst piercing through cold air effortlessly - so you feel the heat faster, and it doesn’t just disappear into the air like with convection heaters. It’s efficient, focused, and incredibly comfortable.
The compact bar design makes it ideal for mounting high up on the wall or ceiling, keeping it well out of the way while still covering a solid area with heat. Perfect for garages, workshops, garden rooms, commercial units…anywhere that needs reliable, background warmth without the bulk of a traditional heater.
It’s IP65 rated too, so you can use it in outdoor spaces without worry. Plus, there’s no moving parts, no noise, and almost no maintenance.
More Options For Your Patio
If you're considering the 1.5kW Theia Infrared Bar Heater but need a bit more power or added convenience, there are two standout options in the IR Bar Heater and IR Patio Heater categories that might suit your needs.
The 2.4kW Theia Infrared Bar Heater offers a significant boost in heat output, making it ideal for larger spaces or areas with higher heat demands. It maintains the same sleek design and efficient carbon fibre heating element as the 1.5kW model, ensuring consistent performance and aesthetics across your setup.
Alternatively, if you're looking for more control and smart features, the 1.5kW Theia Wi-Fi Remote Controllable Infrared Bar Heater could be the perfect fit. It combines the compact size and efficiency of the standard 1.5kW model with the added benefits of Wi-Fi connectivity and remote control, allowing you to adjust settings conveniently from your smartphone or included remote.
IR Heat For Your Outdoor Spaces
When you’re heating colder or more open spaces, not all heaters are up to the task. That’s where near infrared really comes into its own.
Unlike traditional convection heaters that try to warm the air (and end up wasting energy in drafty or open areas), near infrared heats surfaces - including people, furniture, floors, and walls. So even when the temperature drops or the wind picks up, you still feel properly warm.
This makes it perfect for outdoor spaces like patios, terraces, garden rooms, or chilly garages and workshops. The heat doesn’t float away—it stays exactly where it’s needed.
It’s fast, too. Infrared heats up almost instantly, so there’s no waiting around for a room to “warm up.” You flick it on, and within seconds, you’re feeling the difference.
Plus, there’s no noise, no moving parts, and no ongoing maintenance to worry about. Just efficient, targeted warmth, right when and where you need it.

Excellent heater for quick heating & very easy to install. Suggestion: As there are 2 heating elements, replace swithcing arrangement to facilitate Full Power, Half Power and OFF. Presently Full Power or OFF

Installed at my parents’ place. It’s subtle, warm, and doesn’t spoil the evening atmosphere.
