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.

Truly powerful outdoor heat
I researched infrared heaters for ages before settling on this one. The Theia model stood out because of the power rating. It really delivers on that promise. The heat is intense and very effective. It has changed our outdoor space entirely. We used to only use the patio in summer. Now we are out there in autumn as well. The low glare is a major selling point. You get the warmth without the harsh light. I spoke to Simon on the phone to confirm the mounting distance and he was knowledgeable and helpful. The whole buying process was efficient. The delivery was fast and the item was well-protected. Installation was a simple task. The heater is robust and looks sleek. It feels like a high-quality product. It is exactly what we needed to get more use out of the garden. The service was top-notch, and the heater itself is brilliant. I am very pleased with the decision to buy this. It is a solid 5 stars. Everything was perfect.

Changed our home life
We bought this heater after reading about the low glare features. We had a very bright heater before that we rarely used because it was so annoying. This Theia unit is different. The heat is focused and powerful. It has changed our lifestyle. We spend almost every evening in the garden now. We just switch it on and the space becomes cosy. I called in and spoke to Georgia. She was friendly and gave me good advice on where to place it for maximum coverage. The service was excellent. I am really pleased with the whole experience. The heater arrived quickly, perfectly packaged, and was easy to install. The design is unobtrusive and fits in well with our garden decor. I have nothing bad to say about it. The performance, the service, and the quality are all high level. It feels like a high-end product. I would recommend this to anyone looking to improve their outdoor area. It is a genuine 5-star experience from start to finish.
