Indirect Fired Heater Rental Solutions for HVAC
Indirect fired heater rental to heat while preserving clean, dry, flame-free, and fume-free conditions
We provide indirect heater solutions for moderately high temperature rise applications where clean, dry air and reduced fire risk are essential.
In environments like construction sites and warehouses, heating requirements need to be carefully balanced against the impact on safety and key processes. When HVAC heaters introduce flames, fumes, and local emissions, they can quickly affect safety, efficiency, productivity, and product/service quality. Indirect heaters keep any flames and fumes away from the area you need to heat.
At Aggreko, we deliver indirect-fired heater rentals to support applications like comfort heating, drying confined spaces, and curing concrete in construction. With solutions available up to 1,500,000 BTU, we’ll help you:
Keep workers safe and comfortable all year long
Heat your environment without noxious fumes or humidity
Prevent mold growth by controlling moisture levels.
Accelerate processes like paint drying and concrete curing
Reduce fuel costs compared to direct-fired heaters
Meet your sustainability goals by reducing your fuel consumption

Frequently asked Questions
An indirect-fired heater uses a heat exchanger to warm air without direct contact with combustion gases – providing clean, dry, and fume-free heat. It’s ideal for enclosed spaces and moisture-sensitive environments.
Choosing an indirect-fired heater begins with consulting our specialist engineers. They assess your project’s size, heating requirements, fuel availability, and environmental conditions to design a custom solution. Our heaters offer clean, fume-free air, making them ideal for enclosed spaces and moisture-sensitive applications.
With an extensive fleet and wide-reaching distribution network, we can deliver and install indirect-fired heaters quickly after project scoping. Our team manages delivery, setup, and integration to meet tight project deadlines.
Direct-fired heaters heat air by burning fuel directly, releasing combustion gases into the air. Indirect-fired heaters use a heat exchanger, delivering clean, fume-free air, making them safer for enclosed or sensitive areas.
We prioritize safety and environmental responsibility. Direct-fired heaters pose higher risks of fire, carbon monoxide exposure, and moisture buildup. We offer indirect-fired heaters exclusively to provide clean, safe heat without harmful emissions – ensuring safer environments for workers and sensitive operations.
