REZNOR-UDAP225

Reznor has a long-established reputation for providing quality heaters in a variety of spaces. The UDAP225 unit heater was created to improve upon Reznor’s already excellent technology, and feature improved efficiency, easier installation, and a new design both in and out.

With an industry leading 83% thermal efficiency and 12 different sizes, the UDAP series of heaters offer exceptional heat performance for areas both large and small. This unit, the UDAP225 (225,000 BTU), is approved for commercial use only, and is ideal for midsize to large warehouses, industrial spaces, and barns. Feel free to contact us for a more specific calculation for BTU sizing requirements.

Reznor unit heaters can be mounted using either 2 or 4 suspension points. For a simpler installation, add on our Quick-Sling mounting bracket. Thermostat setup is simple, with a low-voltage terminal strip on the outside of the cabinet that makes connecting control wiring simple with no panels to remove. All units also have a factory installed gas line nipple to the exterior of the cabinet, for easy gas service connection.

Reznor is constantly making improvements to their unit heaters. A key new feature is the patented TCore2 titanium stabilized aluminized steel heat exchanger. They also added a "G" terminal to the easily accessible rear terminal strip which allows for easy setup of fan only operation. A sleek new look makes for a clean front and bottom with no visible hardware. Reznor's unique style with it's deep red louvers, white cabinet, and angled corner let you know that you have purchased the top heater.
