"Where can I...?"

The following Herschel Heaters have certification for USA and Canada and can be purchased for commercial use there: Herschel Summit Herschel Colorado Herschel California Herschel Miami  


Quality & Safety

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

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

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

  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


Installation Questions

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

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

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

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

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


Controls Questions

Please see our handy video demonstrating how to ‘pair’ the Herschel iQ R1 Receiver with the Herschel iQ T1 Thermostat. Full instructions are also detailed within the R1 instructions you would have received. The T1 and R1 pairing video is

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

Our Herschel iQ App is simple and easy to download and use with the iQ system. Simply choose which thermostat works for you, add the Hub and download the iQ App from the links below.   Download the iQ App here on

Herschel thermostat controls have been designed to be easy to set up and run however sometimes we all need a bit of help and support. Our thermostat controls help centre has been designed to quickly & simply guide you to

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.

Functional & Technical

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,

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

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

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
