Frequently Asked Questions

What is an indirect-fired heater?

An indirect-fired heater, like the Heatstar HSP500ID-A, has a heat exchanger that separates the flame and combustion byproducts from the air being heated. This ensures only 100% clean, breathable air is circulated, making it the safest option for enclosed or poorly ventilated spaces.

How is the HSP500ID-A's capacity "field-convertible"?

This unit can be switched from 400,000 to 500,000 BTU/h by simply swapping out the fuel nozzle. This unique feature allows you to adapt the heater's output to different job sizes without needing to buy a separate machine.

What is the advantage of its high airflow (CFM)?

With an airflow of 4,032 CFM, this heater can push warm air through up to 100 feet of ducting. This is ideal for heating large, multi-story buildings or distributing heat to several different areas from a single unit.

Is this heater easy to move around a jobsite?

Yes. Despite its power, the HSP500ID-A is designed for mobility. It features a heavy-duty frame with pneumatic wheels and a lift bracket, making it easy to move and position exactly where you need it.
