Product Description

If you’re looking for a beautifully sleek and modern heating panel that will make your room look gorgeous while also providing effective, environmentally sound warmth, the 350W Sienna UltraSlim Picture NXT Gen Infrared Heating Panel is a fantastic choice. Featuring a swirl of teals and oranges, this image creates a lovely modern feel that is very relaxing to look at.

There’s room for a little extra customisation to boot, as you can choose what colour frame you’d like for this panel. Choose from sleek silver, sophisticated black or a simple white, whatever will suit your look best! We think the white contrasts wonderfully with the black highlights of this design, but all three look amazing!

This 350W heater can heat a moderately insulated space of around 5-6m2.

How Does IR Work?

Our IR heaters release Infrared Radiation into your room. These rays bounce around the room, being absorbed by the objects and surfaces they bump into. This warms those objects up! This is a quick and effective process, one that you can feel the effects of as soon as you turn your heater on.  

Did you know that Infrared Radiation makes up more than 50% of the radiation emitted by the sun? It’s a perfectly safe process, and so our IR heaters create a beautiful dry warmth that feels like stepping outside on a summer day!

All in, this is a very efficient way of heating your home, and that increase in efficiency results in loads of benefits, including saving you money on your heating bills!

FIR Coating For Maximum Efficiency & Safety

Our infrared panels come with a brand new, highly advanced premium FIR Coating to help maximise the performance of your heater. It’s heat-resistant – meaning it can withstand temperatures up to 200°C without yellowing over time.

Not only that, but it will also help the carbon crystal heating element inside the panel distribute the IR waves better than ever before, thanks to a higher thermal efficiency, resulting in even more warmth in your home.

To top it all off, the coating is also far more secure than ever before, as it is fire resistant, ensuring your family and your home stay safe and warm.


Our NXTGEN heaters are exceptionally smart and efficient, designed to be compliant with Lot20 regulations. This also has the added side benefit of making your heater much simpler to use in your daily life.

If you love the idea of a heater that turns on when you wake up without you having to think about it, NXTGEN panels have a 7-day timer, so you can give your heater a schedule for each day of the week, adapted to your timetable. For extra efficiency, the Adaptive Start functionality will analyse the temperature of the room before the set time, so it can switch itself on at the perfect moment to get your room to the right heat at the right time.

NXTGEN panels can even sense when you’ve opened a window- specifically if it senses a drop in temperature of 1.5°C over the space of 3 minutes. This is a great option if you want a heater that you can set and forget.

Low Maintenance

One major difference between IR heaters and convection heaters is that the former requires almost no maintenance, while the latter requires regular touch ups.

This is because IR heaters have no moving parts and aren’t reliant on an expensive central boiler system. Each one is its own self-contained unit. This results in a simple installation process, and once they are installed there’s very little you need to do to keep them functional- just occasionally wipe down the surface to keep it dust free.

Sleek Finish

At only 22mm thick, this panel is incredibly slender, especially when compared to traditional radiators. This gives them an incredibly stylish and contemporary look, one that is discrete enough to suit just about any home.

If your tired of having your room design needing to factor in space for radiators, these panels can be placed just about anywhere, and resemble paintings more than heaters.

Explore Our Range

Wall art is a fantastic way of enhancing any room. Our collection of image panels marry practical heating and gorgeous looks, with a huge variety of images for you to choose from. We’ve picked out a few of our favourites to help you make your room shine!

To start with, you can also get this same design on a 350w square panel or a 580w panel, which might better suit your home.

For a panel that uses a similar colour palette, but has a very different feel, the 350W Tangerine Dream UltraSlim Image NXT Gen Infrared Heating Panel uses real world photography to great effect.

For a more mature feel that still has a natural looking fluid design the 350W Dancing Smoke UltraSlim Picture NXT Gen Infrared Heating Panel is especially good in darker rooms.

Keeping Returns Simple

Our heaters come with a free 14-day trial period, giving you plenty of time to test your heater and decide if it works for you. There’s zero risk attached, so you can take a chance on revolutionising your home without stress.

Not only that, we also offer a fantastic 2-year warranty policy. Need more? You can extend this warranty to five years at no extra cost.
