Reznor UDAP is the legacy model of the Reznor UDX
Across multiple BTU sizes (45,000 to 150,000), owners report fast heat-up times—such as raising a 950 sq ft garage from 35°F to 70°F in 15–20 minutes, heating a 60x40x16 shop from 58°F to 70°F in 35 minutes, and maintaining 60°F at -11°F in a 35,000 cubic foot space—with generally quiet operation and straightforward installation, sometimes completed in about four hours. Buyers also note durable long-term performance (including a 1996 unit still running and another used for three seasons), easy replacements of older Reznor models with minor vent modifications, strong packaging and shipping experiences, and occasional issues like an incorrect conversion kit or poor delivery handling that were resolved through customer support.
