Even in the dead of winter, your construction site, events, and warehouses need heat. Choosing the right heater for your space matters, and knowing the differences between direct and indirect fired heaters can help you decide which is the best fit.
These heaters are often popular for construction sites and larger indoor spaces. They run on anything from oil, natural gas, diesel, or propane. The flame of an indirect fired heater is contained in a chamber, and when air is pulled into the intake vent, it's warmed as it moves across the heat exchanger.
The appeal of indirect fired heaters is that they make cleaner and dryer air because the unwanted fumes are filtered out, and there is less humidity than other heaters. However, these heaters are not convenient since they're so large, affecting their overall efficiency and making precise temperature control more difficult to achieve.
In a direct fired heater, the air comes into direct contact with an open flame, and the burner combusts when the fuel encounters that flame. Because the fuel meets the flame, it creates carbon monoxide, so this heater is only functional in very ventilated spaces.
This type of heater is incredibly efficient because it uses all the available fuel to create heat, giving it more power. Since these heaters tend to be smaller, direct fired heaters are more affordable, and it's easier to maintain their longevity.
The need for fresh air and ventilation limits the use of direct fired heaters. You need excellent air circulation and large spaces; otherwise, there is a danger of carbon monoxide poisoning.
Both types of heaters have their own benefits and drawbacks. Your choice will likely largely depend on the kind of space, the intended use, and the portability or convenience you need to get the job done.
Renting a heater for your next project or event can get you the right heater to suit your needs at an excellent rate.
