Ultratherm heaters produce long wave infrared heat. This wavelength is invisible to the human eye and heats the objects in the propagator rather than the air directly. This method of heating is similar to the sun and is very similar to a natural environment. The surfaces of heat mats and strips do warm up but provide a very gentle warmth. Ultratherm heat mats should always be used with a suitable propagator thermostat.

Ultratherm heaters are excellent primary heat sources for most applications requiring night time heating as they emit no visible light and are widely used for this purpose.


Ultratherm heat mats and strips have been manufactured in the UK for more than 20 years and comply with the European standards


All mats and strips are IPX4, double insulated and are marked. The mats/strips have a surface power of 215W/m² and are designed to operate on a 230V~ supply.
