Gas Unit Heaters

Commercial and industrial gas unit heaters produce a lot of heat without taking up a lot of space. Factory-built for natural gas or propane, gas-fired heaters are common in warehouses, gymnasiums, boiler rooms, distribution centers, and other big, open spaces. In most climates and temperature control situations, these units are more cost-effective than electric heaters in these types of large spaces.

With power vented, separated combustion, low profile, and upright designs, natural gas unit heaters and propane unit heaters are versatile and dependable. You can rely on trusted industry leaders like Modine, Sterling, Beacon Morris, and Re-Verber-Ray to engineer the specialized heating solutions you need for your specific application.

At NorthStock, you have access to hundreds of hanging gas heaters and parts—take a closer look at our offering:
