Commercial and industrial indoor gas heaters are small but mighty: those compact units produce a lot of heat. That characteristic makes them ideal for large, open spaces like warehouses, distribution centers, gymnasiums, and boiler rooms. There are hundreds of models of gas unit heaters in power vented, separated combustion, low profile and upright designs with different heat exchanger types. They are factory built for propane or natural gas.

Gas unit heaters can be up to 97 percent efficiency with Modine's Effinity—North America's most efficient gas unit heater. Gas heaters in most climates/situations will be more cost-effective than electric heat while offering a consistent, reliable heating solution for your facility. You can get gas or propane heaters with blowers to direct the hot air or decrease drying time in your manufacturing plant. We have a large inventory of hanging heaters, and we're ready to ship them to you—free in the lower 48 states.
