Industrial and commercial heaters
These are ideal for bigger situations in warehouses, factories and other commercial applications. Working on the same principle as smaller domestic heaters; they can either be convection or radiant, gas or electric.
Industrial heaters tend to be of a more robust construction than domestic heaters. In smaller industrial units this is the main differing factor to domestic units. At the upper end of the spectrum the larger heaters have a much higher BTU output of 100,000BTUs +.
