The Benefits to Heating with Reznor UDAP Series Heaters

Life and work shouldn’t stop for below-freezing temperatures. Without a proper heater, however, cold air can cut right through the walls, making any living or work environment absolutely unbearable. This is true of any indoor space, but especially of warehouses and garages, where walls may not be as well insulated and large doors allow massive amounts of cold air to directly enter inside. For these kinds of spaces, you want a heater that is powerful enough to produce and circulate a sufficient amount of heat, as well as one that is energy-efficient, cost-effective, safe, and reliable enough to last through the years.

Reznor’s UDAP line of high-efficiency, gas-fired unit heaters is all of this, and we could go on all day about what a difference installing a Reznor heater in your warehouse or garage would make. For simplicity’s sake, however, here is a concise list of five features that make Reznor heaters a great choice for helping you through the winter months.


1. Highest efficiency in its class

UDAP heaters boast an 82-83% thermal efficiency, which represents the percentage of gas that is turned into usable heat. Wasting less gas means wasting less money as well as less natural resources, and the added efficiency allows for greater heat potential — Reznor heaters are capable of making indoor temperatures upwards of 60-degrees (F) warmer.

2. Suitable for both professional and residential use

Reznor UDAP heaters are certified for commercial/industrial heating application, as well as approved for use in residential garage/workshop heating applications. From professional warehouses to your personal garage, any Reznor heater will do.

3. Easy installation

These series of heaters hang from the ceiling, from either 2 or 4 suspension points or by an optional hanger kit. A factory installed gas line to the exterior of the cabinet allows for easy gas service connection, and a low voltage terminal strip on the outside of the cabinet makes connecting control wiring easy as well.

4. Engineered for safety

UDAP heaters are equipped with a multi-try direct spark ignition as opposed to an always-on pilot light, which decreases chances of accidental combustion significantly. These units also feature a full fan guard for added safety, and diagnostic indicator lights to allow you to address any issues that arise quickly and accurately.

5. Available in a wide range of sizes to suit virtually any space

Ranging from 30,000 to 400,000 BTU/hr, UDAP heaters are available in 14 different sizes to accommodate nearly any space in need of heating. From the largest warehouses to the smallest sheds, there is a Reznor unit available for you.
