Heat Star f105509 Forced Air Propane Heater 170000 Btu/h

Product Description

The HEAT STAR f105509 is a forced-air propane heater rated at 170,000 BTU/h, built for temporary heat in construction sites, warehouses, barns, and large work areas. It features patented Quiet Burner Technology, which the manufacturer states runs 50% quieter than standard forced-air propane heaters. A 20-foot propane hose and regulator are included, allowing direct connection to a portable propane tank. The unit ships ready to work with no additional accessories required. At 25.7 pounds, it is portable enough for a single technician to reposition on the job. This heater is installed and serviced by HVAC technicians, contractors, and qualified tradespeople working in temporary or spot-heating applications.

The f105509 is suited for residential construction, commercial job sites, agricultural buildings, and large unheated spaces requiring high-output temporary propane heat. The included hose and regulator support connection to standard portable propane cylinders with a tank capacity of up to 11.98 gallons. This unit is designed for open-area use where adequate ventilation is available, as forced-air propane heaters produce combustion byproducts and require proper airflow to operate safely.

Compatibility

Designed as a portable forced-air propane heater for temporary heating applications in construction, agricultural, and commercial environments where a high-output propane heat source is required.

Installation Notes

This unit is intended for use by qualified tradespeople familiar with propane equipment and temporary heating setups. Always shut off the propane supply at the tank before connecting or disconnecting the hose and regulator. Use only in well-ventilated spaces — forced-air propane heaters produce carbon monoxide and must never be operated in enclosed areas without adequate airflow. Inspect the hose and regulator for damage before each use and follow all applicable local codes governing temporary heating equipment on job sites.
