Why Choose Espar/Eberspächer & Proheat Mobile Fuel-Fired Heater Units

Fuel-fired heaters use fuel combustion and heating fluids contained in coils to transfer heat. They are commonly used for commercial mobile transportation units, warehouses, and applications that do not rely on a building’s main HVAC system.

The different types of fuel-fired heaters include:

  • Gas-Fired Duct Units – Conveniently designed with pre-wired or pre-piped assembly to fit in the process’ ductwork.
  • Oil-Fired Duct Units – Ideal for applications that require a non-flammable solution for heating the space.
  • Direct-Fired Heaters – As the name suggests, the flame comes into direct contact with the air to provide heat.
  • Indirect-Fired Heaters – Involves passing air over an enclosed heating element to heat the space.
  • Radiant Heaters – Radiant heat transfer delivers heat directly from the hot surface to an object via infrared radiation.
  • Gas-Fired Make-Up Air Units – A gas-fired make-up air unit ventilates the space by introducing fresh air from outdoors to maintain good air quality. These units provide heat for both indoor and outdoor use.
