Indirect-Fired Heaters

The indirect-fired heaters at Cross Hire resemble your home’s gas or oil burning furnace in functionality. These propane or natural gas run units consist of a flame that is placed in a burn chamber. It heats a component known as the heat exchanger. The cold air drawn into the two chambers is heated and released. The air that is released warms the environment.

  • Since the heat circulated in indirect-fired heaters is never subjected to direct flame, the released air is 100% clean and dry.
  • These heaters come with a built-in thermostat.
  • Indirect-fired heaters can operate safely in closed spaces because they do not release carbon dioxide.
  • An indirect-fired heater is complicated and needs numerous working parts for operation due to which it only achieves 80% efficiency.
  • Their rental cost is approximately 4 times of direct-fired heaters.
  • They cannot function without an electrical outlet.
  • Their installation is troublesome because they require exhaust ventilation, which results in either setting up or tearing down of ductwork.
  • They are large in size, which makes them difficult to transport.

  • Indirect Fire heaters have a simple built, which makes them easier to transport.
  • They are more powerful as compared to indirect-fired ones.
