A Universal propane heater refers to the heater models belonging to the Universal brand that are powered by propane rather than natural gas, diesel or kerosene. The Universal portable heaters that are powered by propane are, as of 2015, designed for use at construction sites.
The three types of Universal heaters that can use propane as fuel are the convection, forced-air and radiant heater models. The convection heater model can heat up an area of between 2,000 to 3,900 cubic feet. This heater model does not require any kind of electricity to operate and does not produce an odor when it is burning fuel.
