  • Description

    For a long time Reznor has been providing the best heaters for a variety of applications. The UDAP45 unit heater was created to improve upon Reznor's proven technology. It features a new design both in and out, easier installation, and better fuel efficiency.

    Offering an impressive 83% thermal efficiency, Reznor’s UDAP unit heaters produce high-quality heat performance and are available in 12 sizes to heat spaces both large and small. The 30,000 - 125,000 BTU models are all approved for use in commercial settings as well as attached residential garages, including this unit, the UDAP45 (45,000 BTU), which is ideal for smaller spaces. Call or email us for an estimate of the number of BTUs you need for your location.

    Reznor unit 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. 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 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.
