Installation & Maintenance

They come with brackets for easy wall and ceiling mounting. The brackets are also adjustable, meaning you can tilt the heater to the desired angle. As there are no moving parts, there is no maintenance required. They can be cleaned with a damp cloth when switched off

This 1800w bar heater come with a 13 Amp 3 pin plug, however we do recommend to hardwire it to your mains via a fused spur

Safety is paramount, which is why our heaters come equipped with advanced safety features such as overheat protection and compliance with industry standards (CE, UKCA, TüV, GS). The bar heaters can reach a surface temperature of approximately 200-300˚C, significantly hotter than traditional radiators, therefore they must be installed safely out of reach above 1.8 metres, eliminating any risk of accidental burns.

Where Can I Use Infrared Bar Heaters

Infrared bar heaters are a powerful solution for larger, harder-to-heat spaces. Their slim design and high output make them ideal for both domestic and commercial areas where targeted, high-performance heating is essential.

Domestic Applications

  • Larger Rooms and Conservatories: Perfect for open or glazed areas where greater heating capacity is needed to stay warm during colder months.
  • Kitchens: These compact, high-mounted heaters are ideal for rooms with limited installation space. Their discreet profile keeps them out of the way of cupboards and appliances.

Commercial Applications

  • Offices and Workspaces: Great for larger, open-plan office environments where more powerful heating is required in specific zones.
  • Warehouses and Workshops: Bar heaters deliver focused warmth in areas like loading bays, workstations and picking zones. An efficient way to improve comfort without heating the entire space.
  • Restaurants and Bars: Ideal for both indoor dining areas and covered outdoor terraces, enhancing the customer experience all year round.
  • Community Halls and Places of Worship: Their high wattage output makes bar heaters a cost-effective choice for large open spaces with high ceilings and intermittent occupancy.

How Infrared Heaters Work

How Do Infrared Heaters Work?

Infrared heaters work differently from traditional convection heaters. Instead of warming the air, they emit invisible waves of heat that are absorbed directly by objects, walls, and people, just like natural sunlight, but without the harmful UV rays.

This means the warmth is felt faster and lasts longer, even when doors or windows are open. Because they don't rely on circulating hot air, there's no dust movement, no drafts, and no wasted energy heating unused space above head height.

Far infrared is especially gentle and effective. It penetrates just under the skin to provide a deep, lasting warmth that feels natural, comfortable, and efficient. It's completely silent, safe, and perfect for both homes and commercial settings.

In short, infrared heating offers a smarter, healthier, and more economical way to stay warm — all while reducing your carbon footprint.

Great heater.

I have only just had this heater installed. Installation was easy and once set up on the app appears to be very easy to use even for a technology novice.
I did need a friend to do this for me.

Good Heater for Caravan

Using one of these to provide some heat for our dogs on cold nights, the dogs live in our old static caravan. The oil boiler we used previously stopped working so thought we would give an infra red heater a try and it works well.
The first heater we purchased had a fault and had to be returned but we have had no issues with the replacement. Return process was all handled by the seller and hassle free as they were happy for us to keep the original fittings so the install of the replacement unit only took a couple of minutes. All in all would recommend and will definitely use again if we decide to get any more heaters for our own house or decide to fully renovate the caravan at some stage.

Works very well in a kennel

I am so pleased with this heater. I did need help to fit it and to get it working on the app but I'm not very technologically minded. It's now very easy to use and adapt even when away from home. My dog is very grateful for it on cold days when I'm at work.

I bought a bar heater from this company 3 years ago . I was given very good advise on what size I needed for the size of my studio and my bar heater not only looks stylish high up on the wall it heats up the space perfectly and economically .My only problem is I can’t always find the remote so I’ve just ordered a spare .

Ordered 2 infra red heating panels from this company and they were delivered very promply (by a decent carrier no less) and in good order. Only fitted the 1200kw heater so far and very impressed with performance and ease of installation (plug in model). Provides good heat and does what it says on the tin.

The engagement, advice and general customer service from this company has been exemplary. They will be my first port of call for any other heating needs.

I spend my day in the office at home. The panel is connected to a smart plug and I say 'Alexa, turn panel on for 30 minutes'
Saves a fortune on not needing to heat the whole house to warm one room and the heat is localised and perfect.
I would describe it like sitting by a window with the sun shining through

Couldn’t agree with the other reviews more. Great product and great people. It’s great to get such fantastic customer service. Keep up the good work! 😁

Tobin Parsons

After a lot of research, we decided to swap out our gas central heating for infrared. We bought all of our panels from Mohammed at Infrared Heating Supplies Bolton. We are so happy we went down this route, as they are performing well and are very cheap to run. We particularly like the fact we can control each individual unit in specific zones from our phones which means we can use the panels as and when we need them and set timers which is particularly useful in the mornings when we come down to a warm space. Additionally, they are very low wattage; we have 700 watt heaters in our double bedrooms and 450 watts in the single bedroom. The living room which is approximately 6.6 x 3.5 m is warm enough using only 2 panels (700w and 450w). Thus we have seen a significant saving in our energy bills.

I would highly recommend Infrared Heating Supplies as they are very customer focussed and they provide a very competitive and superior alternative to air source heat pumps.
