Mestek xf175a1ns1110 Commercial Unit Heater 175000 Btu/h

Product Description

The MESTEK xf175a1ns1110 is a commercial gas-fired unit heater rated at 175,000 BTU/h on natural gas, designed for large-space heating in demanding industrial and commercial environments. It operates at 83% thermal efficiency using single-stage direct spark ignition and features an aluminum heat exchanger for corrosion resistance and consistent heat transfer. The unit runs on 115 volts and is equipped with a 1/3 HP open drip-proof (ODP) motor. Power-vented operation supports both standard vent and separate combustion air configurations, giving installing contractors flexibility in tight or contaminated-air mechanical spaces.

This unit heater is built for commercial and light-industrial applications where dependable overhead heating is required. Typical installations include warehouses, manufacturing facilities, loading docks, garages, and large storage buildings. The power-vented design with optional separate combustion air makes it suitable for spaces where indoor air quality or negative pressure concerns would otherwise limit heater selection. Installation is performed by licensed commercial HVAC or gas-fitting contractors.
