Outdoor heaters are becoming increasingly popular, but there are many different types of heater available and lots of jargon. But even on the nicest of days in the UK it very often gets chilly or cold in the evening and if you want to enjoy socialising outside, outdoor heating is a must. So we’ve put…Read more

Quality & Safety
Herschel Infrared heaters 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 panel heaters require no maintenance or servicing. Our heaters use solid state elements unlike water-based heating or fan-assisted systems,…Read more
Longest track record At Herschel we have the most extensive experience of the application of Far Infrared in the UK (check our Residential and Commercial Case Study pages). Effective heating is all about matching the right heater to the right requirement and we have many years experience in this: helping us develop not only our…Read more
Are Infrared rays safe for people? Far infrared heating is 100% safe and natural for our bodies, and our well-being, as the human body is designed to accept and emit infrared. The feeling of warmth from infrared is particularly comfortable. It is UV that is harmful, not infrared, and so there is no need to…Read more
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…Read more
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 and EcoDesign (Lot 20) Compliant. Click here for more detailed information.
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.
Herschel Infrared panels are easy to install and come with a very comprehensive set of instructions. As Infrared panels are an electric installation, they should only be carried out by a suitably qualified electrician. Herschel has a network of Accredited Installers who would be happy to help you. Things to consider when planning to install an…Read more
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…Read more
To allow the panels to operate at the right temperature and unobstructed, our Instructions call for no objects to be placed within 400mm of the front of the panel and not within 200mm of the sides of the panel. This includes if you are intending to flush-mount panels in a plastered ceiling where you must…Read more
Very occasionally we get asked about decorating problems that show up around heaters and whether the heaters are to blame. However on the rare occasion that we do, in all cases there are underlying problems which the heater – in fact, any heater – is just accelerating or making evident by simple virtue of it…Read more
Electrical Safety in bathrooms divides into four zones. In Zone ‘0’ which defines being within in the sink bowl, bath tub or shower bowl any electrical appliance must be IP67 (full immersion capable) and low voltage. Zone 1 is the splash zone above a bath or within a shower enclosure and extends from the floor…Read more

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…Read more

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). So some kind of controller is needed with your infrared panel. We do not build thermostats into our heaters because it is the temperature of the…Read more

Functional & Technical
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…Read more
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…Read more
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…Read more
There are some disadvantages to infrared heating panels compared with other forms of heating, but these are far outweighed by the many advantages. The main consideration is that the infrared heating panels must not be obstructed by furniture. Infrared heating panels radiate invisible light (which carries the heat). If they are obstructed, for example by…Read more
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…Read more
There are no maintenance and servicing costs related with Infrared heating panels. There are no moving parts or liquids or gases that require any form of annual maintenance contract. The other major benefit of Infrared panels is that in the rare case one should go wrong, you only need replace the one that has gone…Read more
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…Read more
SAP10 is coming and the future is electric. Please read our our latest news on SAP10. The proposed introduction of SAP10 has significant implications for electric heating given the revision of emission factors which are currently out of date. Overview of current methodology SAP2012 SAP is the Standard (buildings) Assessment Procedure and it is used…Read more
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…Read more
We could get really geeky on this but will try to keep it simple… Whilst both Herschel Inspire and Select XLS panel ranges 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 XLS Panels average…Read more
