A Guide to Reznor Garage Heaters

When it comes to heaters, few brands can boast the same level of experience as Reznor. Ever since it started in 1888, Reznor HVAC has 130 years of rich history making HVAC products, both for residential and industrial use. 

The company has built a reputation for high-quality and reliable products covering heating, cooling and ventilation needs. More than just a leading brand, Reznor founded several industry firsts, such as the first gas-fired unit heater in the US in 1920, as well as the first gas-fired industrial heater in 1935.

Reznor’s Garage Heaters

Reznor’s products have a well-deserved reputation for rugged reliability and longevity, and their garage heaters are no exception. Our Reznor garage heater lineup comes in a wide range of BTU models to suit different spaces, from 30,000 all the way to 400,000 BTU and options for both residential and commercial applications.

Each heater also boasts a sleek build and redesigned heat exchangers that offer industry-leading performance, worthy of the storied brand.

Reznor UDXC and EUH Lines of Unit Heaters

Reznor offers five lines of unit heaters:

Model Line	Description	Fan type	Application	Availability
UDXC	Separated combustion or standard power vented natural gas unit heaters (convertible to propane). This sereis replaces the UDAP, UDX, and UDZ unit heaters.	Axial	Commercial, Industrial, Residential	In Stock
EUH	Electric unit heaters	Axial	Commercial, Industrial, Residential	In Stock

Fan type

An axial fan is one where the blades spin around a central shaft to pull in air. They generally have a high flow rate, but low pressure. They also require less power to run.

A blower or centrifugal fan works differently: it pulls in air from a side intake and blows it out through a 90-degree angle duct. The result is a lower flow rate due to the ductwork, but higher airflow pressure. This allows them to generate a steadier flow of air at the cost of higher energy consumption. If you are looking for a Reznor heater with a blower style fan, please contact us.

Venting Options

UDXC series heaters offer either standard power venting which uses air from the space for combustion or separated combustion which draws air in from outside. Separated combustion is recommended for spaces with dust or chemicals in the air like paint or wood shops, or for spaces that are very tightly air sealed. If you opt for separated combustion, a separate kit is required. 

The electric EUH series does not require any venting.
