Heaters - 500,000 BTU Indirect Fired

These indirectly fired, exterior vented temporary construction heaters put out 500,000 BTU through two ducted outlets. Pipe hot, dry air into your construction site to keep your crews working and materials warm all winter long. A return air line offers efficiency advantages and keeps running costs low. These units sit outside the building, run on propane or natural gas, and transfer clean, hot, dry air into the building through flexible ducts.
