> Construction leaders can optimize jobsite conditions by understanding three distinct heating approaches tailored to different environmental demands

## Key points

- Direct-fired heaters provide strong ventilation but higher energy costs.
- Electric heaters allow air recirculation for cleaner ventilation.
- Indirect-fired heaters offer efficient temperature and humidity control.

Block Field

[**David Simpkins**](https://www.linkedin.com/in/david-simkins/), Director of Technology at [**Polygon**](https://marketscale.com/shows/polygon/), delves into the world of construction heating and moisture control solutions in a recent presentation from their North Andover office near Boston. Simpkins introduces three varied heat options that cater to the diverse demands of construction sites, ensuring an optimal climate for efficient operations.

## The Spectrum of Heaters

Simpkins unveils a direct-fired 2.5 million BTU heater, suitable for applications that can manage 100% outside air. However, this powerful unit sacrifices recirculation for effective ventilation, resulting in higher energy costs and combustion products in the airstream. On the other hand, a 150 kW electric heater enables air recirculation either inside the space or adjacent to the building, trading a lesser half a million BTUs for cleaner ventilation. Two versions of the million BTU indirect-fired heaters introduce the option of mixed air – recirculating the inside air while simultaneously drawing in outside air.

## Energy Efficiency and Controlled Environments

These indirect-fired units, functioning like a furnace that secludes the combustion products from the air, present a more energy-efficient option. Moreover, these heaters also provide the prospect of adding desiccant dehumidification, allowing independent control of temperature and humidity. Simpkins highlights how this feature is crucial for certain construction processes that require precise environmental conditions, like drywall drying and millwork installation.
