HeatStar Indirect Fired Portable Heater | HSP400ID-G | 400K BTU/hr | Natural/Propane
HeatStar Indirect Fired Heater — 400,000 BTU/hr | Natural Gas / Propane
✅ OCCUPIED-SPACE SAFE:
This is an indirect fired heater. Combustion exhaust is fully isolated from the heated air stream via an internal heat exchanger, making it suitable for indoor and occupied spaces when properly vented.
⚡ Power Requirement: 120V / Single Phase — Optional Remote Thermostat
The HeatStar HSP400ID-G Indirect Fired Heater delivers 400,000 BTU/hr of clean, safe heat for larger occupied spaces requiring high output. Designed for professional, rental, and contractor use, this unit combines robust construction, extended runtime, and proven indirect-fired technology for reliable performance in demanding environments.
High-Capacity Indirect Heat for Occupied & Ventilated Spaces
The HSP400ID-G uses a stainless steel heat exchanger to isolate combustion gases from the heated air stream, allowing the heater to be placed outdoors while delivering warm, clean air indoors. Powerful fans enable flexible ducting up to 100 ft, and optional thermostats maintain consistent temperature for controlled environments. Heavy-duty construction ensures reliability with minimal maintenance—only one annual service is recommended.
