When it comes to heating large commercial or industrial spaces, indirect-fired heaters are a smart choice for maintaining consistent and controlled temperatures. But what exactly are indirect-fired heaters, and how do they differ from direct-fired heaters? 

This blog post will discuss indirect-fired heaters’ key features and benefits and explain why they’re the preferred choice for many businesses and facilities.

First, let’s define direct and indirect-fired heaters. 

Direct-fired heaters burn fuel directly in the heating chamber, which heats the air circulated throughout the space. 

On the other hand, indirect-fired heaters use a heat exchanger to transfer heat from the combustion process to the air circulated throughout the space. That means that the heated air never comes into contact with the combustion process, making indirect-fired heaters a safer and more efficient option.

One of the most significant advantages of indirect-fired heaters is their ability to provide consistent and controlled temperatures. Because the heat exchanger separates the combustion process from the heated air, the temperature can be easily regulated and maintained consistently. 

This is especially important in large commercial or industrial spaces, where maintaining a consistent temperature is crucial for employee comfort and productivity.
