REZNOR-UDAP125

Reznor is known for engineering quality heaters that can be used for a variety of needs. The UDAP125 unit heater was created as the next generation of Reznor products. It features easier installation, better efficiency, and a new and improved design.

Offering 12 different BTU options and an industry leading thermal efficiency of 83%, Reznor UDAP unit heaters offer amazing performance for all spaces. The 30,000 - 125,000 BTU models are all approved for use in commercial buildings as well as attached residential garages, including this unit, the UDAP125 (120,000 BTU), which is ideal for mid-size to larger spaces. Call or email us for an estimate of the number of BTUs you need for your location.

The UDAP Series heaters are easy to install, secured in place from 2 or 4 suspension points or by an optional Quick-Sling mounting bracket that allows for ceiling mounting. Connecting your thermostat is also a breeze. A low-voltage terminal strip is conveniently located on the outside of the cabinet so that you have no panels to remove. The factory installed gas line input is located on the backside of the unit making the gas connection effortless.

Reznor has made improvements to their UDAP heaters for better performance and quality of use. New features include Reznor’s patented TCore2 titanium stabilized aluminized steel heat exchanger, as well as the inclusion of a "G" terminal to the strip and a newly designed circuit board, which allows for fan-only operation without adding relays. 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.
