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:

A trusted choice for heaters across sectors

Our scale and reach make us a trusted partner for effective, efficient, indirect-fired heaters in several key sectors.

Applications with flame-free indirect heaters

  • Heat localized areas or large spaces without introducing moisture or flames to your environment. Our indirect-fired heater rental solutions include units from 500,000 BTU to 1,500,000 BTU – large enough for open outdoor spaces or small enough for confined environments. All with high flow rates and static pressure, alongside a variety of fuel options including natural gas and propane.
  • Remove moisture from your environment using a commercial indirect heater to defend against mold and safety risks. In ideal conditions, an 800,000 BTU indirect heating solution can remove up to 27 gallons per hour.
  • Speed up time-consuming processes in a construction setting. Our experts can design a turnkey solution to optimize your processes, from preventing concrete carbonization by curing it with clean, dry forced air to accelerate painting and drying.
  • Improve working conditions and safety with indirect heaters with no need for flame fire supervision and no additional noxious fumes or humidity.

Frequently asked Questions

indirect fired heater rental solutions for hvac

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.
