The European Far Infrared Panel Standard is:

A flat surface panel with a surface temperature of 75°C or higher.

An emission rate of least 0.09 watts per centimetre2 over the panel surface.

Must have CE, Electrical Safety, Electrical Emissions, Safe Construction and Intelligent Controls certification.


These requirements are necessary to protect customers by standardising the specification and performance of Far Infrared heaters and meet critical construction, electrical safety and performance standards.

New Ecodesign legislation from the EU 2015/1188 (otherwise known as Lot 20) means that re-sellers and installers of electric space heaters will need to be sure that the heaters they are selling or installing comply with Lot 20 from 1 January 2018.

Heaters that fail to comply will not be able to be supplied or installed in EU member states, so it is vital for re-sellers and installers to be aware of the new legislation.

The EU commission has recognised for a number of years that local space heating represents a high proportion of energy usage and therefore is a key area for carbon emission reductions.  The new legislation is designed to reduce energy consumption. For electric space heaters, this will be achieved by only permitting their use when operated by advanced controls, improving their effective use and minimising wasted energy.

Herschel Infrared heaters together with either the Herschel iQ Single Zone starter pack, T1, or WH1 Central Control Unit are fully compliant with EC Directive 2009/125/EC for Ecodesign of local space heaters. When the legislation comes into place, Herschel will be supplying its heating panels and the iQ controls as part of a compliant product combination.  Herschel outlines that these iQ features not only make the product set Lot 20 compliant, but also best in class. 

Our panels are tested and verified by the German research establishment TÜV and the tests include verification (Geprufte Sicherheit – or “Proven Safety and Health”) and Electromagnetic compatibility with current world standards for human health and electrical appliances. They are also RoHS and REACH Compliant.

We could get really geeky on this but will try to keep it simple…

Herschel Inspire panel heaters are made from a stainless steel filament woven into an insulating material. Herschel Select Panels are made from our COSIX Cell technology, a carbon-based element. Whilst they have different construction methods, they both do the same thing which is to convert electricity to emit radiant heat called “far infrared”. Surface temperatures of the Inspire and Select Panels average 100 degrees centigrade and are designed to gently warm people and buildings.

Herschel Advantage and Aspect range utilise ceramic plate emitters containing nickel wire cores.

Herschel Far Infrared emitters emit in the spectral range of 3 – 10 microns with no light at all.

The Herschel Advantage and Aspect Space heaters have surface temperatures of around 400 degrees centigrade and have a higher throw and spread to heat larger areas.

The majority of the heat produced from all of our panels is “radiant”, meaning the energy is used to directly heat objects and not the air.

Don’t worry, Herschel far infrared heaters are completely safe.

Herschel far infrared heating is 100% natural for our bodies and our well-being.  The human body is designed to accept and emit infrared waves.

Far Infrared heating works on the basis of gentle, long-wave Infrared which penetrates the air and heats solids. If you like the warmth of the sun then you will love the feeling you get from your new infrared heating system. However, unlike the sun our heaters only emit safe infrared heat, not the harmful UV. So, you get the feeling of the sun without the damaging rays (and minus the suntan unfortunately!).

All electronic devices emit electro-magnetic fields in varying levels and collectively this effect is referred-to as “Electrosmog”.

All devices are therefore also subject to regulations governing the amount of acceptable EMF they can produce and reputable manufacturers in Europe are required to adhere to those regulations as part of their CE declaration.

Herschel products operate well within current safety guidelines and standards relating to EMF.

Herschel is also satisfied these standards are regularly scrutinised and updated in light of new research findings in developing technologies, best practice in the industry and legal requirements of health and safety.

This depends on the ambient temperature and the levels of insulation of your building. Herschel Far Infrared heaters work by warming up the thermal mass of the room and on initial start up, this may take several hours and in some cases days, depending on the area to be heated (a damp basement room for example). It is very important to go through this phase to warm the thermal mass of the room for the heaters to work efficiently – cold walls and floors will not give occupants a feeling of warmth and wellbeing. For the system to work effectively all surfaces in the room should be at the same comfortable temperature and will start radiating back.

We recommend leaving the heaters on constantly until the room reaches the desired temperature. They then work most effectively by “topping up” the temperature using a thermostat control, being operated on a timer or a combination of both.

We offer next day delivery to mainland UK on all of our standard stock items. Allow 2-3 days for delivery to Europe.

Inspire glass or picture panels which are a bespoke design take approximately 4 weeks from order to delivery.

You will be advised at the time of ordering if there are any changes to our standard lead times.

Panels are very easy to install.

All you need to consider when installing infrared is:

  • Provision of an electrical source;
  • Ensuring enough strength exists in the wall / ceiling where you are going to hang it.

This makes Infrared significantly easier to install than oil or gas boilers, heat pumps, underfloor heating etc and minor disruption.

As they are electric we do recommend they are fitted by an Accredited Herschel Installer or a suitably qualified electrician.

It depends on the product. Many of our products come with a  plug and can simply be plugged in. However, we recommend that they are properly installed and hardwired to the mains in which case installation should be carried out by a competent person or a qualified electrician according to national regulations.

Herschel accredited installers are fully trained and experienced in installing our heaters and can provide advice on the correct sizing and locating of the panels.

Panels should be sited to maximise the throw and spread of the far infrared heat without obstruction. The panels radiate heat in all directions and any obstructions will interfere with the performance of the panels. Furniture should not be placed directly in the path of the panel. For example, if the panel was sited on a wall ABOVE a sofa this would warm the room and the sofa and would be working effectively, However, if the panel was located low down behind the sofa, the panel would heat the back of the sofa and not the room and would NOT work effectively. This is very different to conventional “radiators” which heat the air and are often sited behind furniture.

Herschel panels radiate far infrared heat through the air which is then absorbed by objects and surfaces of the room. The most effective place for you to mount your panels is usually higher up on the walls or on the ceiling.

The heaters will be less effective if they are mounted directly opposite a window or door as there will be no thermal mass to absorb the energy.

You will feel heat from the panels to a distance of around 2.5-3m, so if you want to have the feeling of the warmth from the panels try to mount them within 3m of where you are normally located within the room.

We recommend you contacting us or one of our authorised distributors, installers or re-sellers for more advice.

Can I paint the panels so they match the same colour as my walls?

Our best advice, following testing in-house, would be to use heat resistant paints such as radiator paint. Normal emulsion doesn’t bond very well (you can easily scratch it off).


Please note, we are unable to give any warranty around the paint itself and so any discoloration of the paint is at your own risk.

Electrical Safety in bathrooms divides into four zones.

In zone ‘0’ which defines being within in the sink bowl, bath tub or shower cubicle any electrical appliance must be direct current and low voltage.

Zone 1 is any zone above a bath or sink or around an unenclosed shower that is prone to splashing. Any electric appliance operated in this zone must have a protection rating of IP44 or higher.

Zone 2 is a 60cm safe zone outside zone 1 to which the same IP44 minimum rule also applies.

“No Zone” is any other area in which theoretically no ingress protection need be applied.

All electrical appliances in a bathroom should be protected with a 30 ma RCD (Residual Circuit Device).

This means that any Herschel panel heater may be installed within zones 1 or 2 (or “no zone”). If you are seeking to install an Advantage or Aspect space heater, please seek the advice of your Herschel Installer, since IP ratings vary.

Ingress Protection requirements in bathrooms

The wires can be chased into the wall and completely hidden or else discretely fitted within cable trunking, in much the same way as you would do when installing any electrical device (i.e. a wall mounted flatscreen TV). Please consult your electrician or a Herschel Accredited installer for more advice.

At Herschel we have the most extensive experience of the application of Far Infrared in the UK and have developed our heaters to provide the best combination of quality, performance and price available. We have the largest range of heaters for the widest range of applications. All of our heaters have been extensively tested to UK and International standards and carry best in class warranties. We are the only UK Far Infrared specialist to provide and insist upon full training and accreditation for our installers, distributors and re-sellers.

Integrity is one of our core values and we will never allow our heaters to be mis-specified or mis-sold. You can be sure that when you purchase a Herschel heater you will be purchasing the right heater for the right application and will have many happy years of use.


Modern immersion heaters and well-insulated cylinders provide a simple and fast means to raise, and store hot water. Thermostat controls ensure the heater is cost-efficient to run.

If you have solar PV you can divert surplus solar electricity to an immersion circuit, rather than sell to the grid. This does NOT effect your 50% deemed export payment. Products such as immerSUN, Power Diverter and Solic 200 are well proven and widely available.

You can also use these devices to divert surplus solar electricity to your infrared panels, if they run on a dedicated circuit. This works best with up to 3kW of heater panels (assuming you have a 4kWp solar PV system installed).

Herschel heaters can deliver energy-savings up to 60% over traditional heating systems.

Providing warmth 24×7 at a fraction of the cost of gas, oil, or other electric heating, infrared warms the fabric of the building – and not the air – which is the key to its energy efficiency.

100% of the electrical energy used by infrared systems is converted into heat. Infrared heaters offer owners an unprecedented level of control over their property’s temperature and energy use.

The amount will depend on each particular house or building and your previous heating solution however it has been proven that a sufficiently insulated building, fitted with infrared panels, can expect significant reductions in energy usage, including:
  • up to 30% reduction on gas central heating systems;
  • up to 50% reduction on oil central heating systems;
  • up to 60% reduction on electrical storage heating.

There is a risk of injury from touching any form of heater and Herschel panels are no different. However, a key benefit of Herschel panels, unlike conventional heaters, is that they can be mounted higher up on walls or ceilings – reducing the likelihood of accidentally touching them or falling against them. We always advise this, especially in areas where young children or the elderly are present.

Our Herschel Inspire and Select panel heaters (excluding our Herschel IR space heating range; Advantage, Aspect, Thermodry and IPR4) have surface temperatures of around 100 degrees centigrade. If you do touch one of these panels you will perceive this as hot on initial contact but, provided you do not continue to touch the panel, are unlikely to scald or burn.

The reason that you can touch Herschel panels without immediately injuring yourself is because a Herschel infrared panel typically has a heat energy or “watt density” of 0.09 watts per cm2 – an energy level that the skin can absorb and conduct away from the area of contact.

It is not the temperature that does the damage but the heat energy in the object.

A kettle, for example, typically has a watt density of between 15 – 30 watts per cm2. The skin cannot absorb and conduct away this level of energy and consequently scalds on the area of contact. Yet, both the Herschel IR panel and the kettle are at 100C.

Warning: Please note that prolonged contact with any heater, Herschel included, will result in injury. Please also note that the Herschel IR space heating range (Advantage, Aspect and IPR4) all utilise Ceramic elements which run at far higher temperatures and would cause immediate injury if touched. These heaters must always be mounted in accordance with our instructions & never be touched when switched on or for 30 minutes after use.

Our heaters all come with a 5 or 10 year guarantee. Our Inspire range is designed to last decades because of the high quality of materials and advanced heating elements that are used. Herschel Far Infrared heaters require no maintenance or servicing. Our heaters use solid state elements unlike water-based heating or fan-assisted systems, which often require servicing, inspection and repair costs. And unlike gas or oil boilers you won’t have to contemplate performing an entire re-installation every 10 years.

Herschel Infrared heaters and control products are certified to national safety standards.

We do not build thermostats into our heaters because far infrared works by heating the fabric of the building which then radiates heat back. Therefore it is the temperature of the room which is important, not the temperature of the panel. Built in thermostats are not as effective because the close proximity of the thermostat to the heater means that it is impossible to correctly measure the room temperature.

In order to emit far infrared at the right waveband, our heaters are either “on” or “off” (it is not possible to vary the temperature of the heater itself). Our heaters can simply be switched on or off at the plug/power source. However, to control the panel and the required heat within the room we recommend the use of a Thermostat. For whole building control and for maximum flexibility we strongly recommend using our Herschel IQ controls system – especially designed to control Infrared heaters.

In addition to our Herschel IQ system we have an extensive range of thermostats from simple plug in, timer control, wired in and wireless.

Herschel Far Infrared emits the biologically most significant Comfort Heating wavelengths because skin content is 80% water which absorbs heat most efficiently from wavelengths of 3 microns and lower (Far Infrared). Far Infrared is better absorbed by the skin, is less transmissive (passes through) and is less reflected.

Infrared wavelengths themselves are divided into 3 distinct categories, due to the different physical characteristics of each wavelength.

Near Infrared”, “IRA”, “Short wave” or “Bright” Infrared heaters and “Heat Lamps” operate between 780 nm to 1,400 nm and emit temperatures of 1300°C and more plus a certain amount of “deep red” visible light. Applications of this technology include heat lamps for food preparation; large volume “Space” heating requirements and certain carefully controlled medical applications.

Medium Infrared”, “IRB” or “Medium Wave “ infrared heaters operate between 1,400 nm and 3,000 nm and emit temperatures high hundreds of °C. Middlewave is valuable for Space heating in cold locations or where there is a lot of airflow due to its more transmissive properties over Far Infrared.

Far infrared”, “IRC”, “Long wave” or “Dark Radiators” operate in the wavelengths above 3,000 nm. Far Infrared elements emit much lower temperatures, typically around the 100°C mark and no visible light. This is the wavelength used in domestic “comfort” heating and Infrared Sauna applications.

“Far Infrared” is consequently the only applicable technology for a “comfort” heating application.

No, just keep them clean with a soft, dry cloth.

With Economy 7 you are probably paying a higher rate for daytime electricity than on a standard tariff. If you intend to run your Herschel panels overnight and also run other appliances overnight then it could make sense to stay on Economy 7. However, depending on your circumstances it is likely that you will also run your panels in the daytime, and it may well be that the extra daytime rates could outweigh any savings. Our best advice would be to run your Herschel panels for a season and then review the situation depending upon your usage,

Don’t forget that the average running cost of using our panels for 5 hours per day will give you a big saving and improved comfort levels compared to night storage heating regardless of whether you are on an Economy 7 tariff.
