Please consult your electrician or a Herschel Accredited installer for more advice.

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…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…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…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…Read more

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…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…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…Read more

With overnight economy tariffs, 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 your overnight tariff. However, depending on your circumstances…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%…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…Read more
