Hot Tips (HVAC)

Wall Heaters

Blustery days with chilling winds can cause heating problems in many facilities with high volumes of foot traffic. While the main rooms within the building may be warm from the primary heating source, many areas are left out in the cold as drafts bring the temperatures down. Vestibules, lobbies, entrance ways, and hallways can see a steady flow of people moving in and out throughout the day, opening doors and letting in chilly air.

In addition to open doors, cold air manages to find its way into facilities by any means necessary—whether it’s through vents, cracks, crevices or unsealed windows. To counteract these cold drafts, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Gentle heating sources are often not powerful enough to provide sufficient warmth in drafty areas. Fan-forced wall heaters however, push back on the infiltrating cold air, ensuring occupants feel the warmth as soon as they enter the building and until the moment they leave. These heating units can stop the drafts before they spread throughout a building, bringing down temperatures and reducing overall heating efficiency.

Fan-forced wall heaters with an automatic delay eliminate cold drafts on start-up and discharge residual heat from the heater body during shut down. This helps attack drafts at their source while making the best use of available heat. In addition, consider fan-forced wall heaters that come with an integrated thermostat allowing for easy adjustment of room temperature to maintain a desired comfort level.

As with any heating unit, it is imperative to select high-quality products that offer protection against common safety risks. In terms of general design, fan-forced wall heaters come with a clear, easily accessible power on/off switch for added safety during maintenance.
