Quartz halogen infrared heaters

Quartz halogen infrared heaters produce short wave infra-red rays and are frequently installed in buildings that are too difficult or expensive to heat using conventional warm air systems. They are particularly suited to buildings that have high ceilings, are poorly insulated, or very drafty.

Quartz infrared heaters have been available for over 10 years during which time they have been installed in workshops, warehouses, loading bays, churches, animal houses, factories, aircraft hangars, gymnasiums etc.

They are also used outdoors under waterproof covers in street cafes, beer gardens, golf driving ranges etc. When they are used outdoors it is very important they are fully protected from rainfall.
