High-Performance Duct Heaters for Efficient Heating

Duct heaters are an essential component in many HVAC systems, providing consistent and controlled heating for residential, commercial, and industrial spaces. Whether you're looking for electric duct heaters or gas-powered options, these systems integrate seamlessly into existing ductwork to ensure uniform heat distribution.

Electric and Gas Duct Heaters for Various Applications

Electric duct heaters are widely used for their efficiency and ease of installation. They provide precise temperature control and work well in both residential and commercial HVAC systems. Gas duct heaters, on the other hand, are ideal for high-capacity heating, delivering powerful performance with cost-effective operation. Both options ensure optimal comfort in ducted heating systems.

Inline and Round Electric Duct Heaters

Inline duct heaters are designed for direct installation within ductwork, making them an excellent choice for space-saving heating solutions. Round electric duct heaters provide even air distribution, improving efficiency in heating applications. Whether you need an inline or a round duct heater, we offer a range of reliable options for your system.

Frequently Asked Questions

Consider factors such as airflow rate, duct size, desired temperature rise, and the specific heating requirements of your space. Consulting with an HVAC professional or referring to manufacturer guidelines can ensure proper selection.

Proper installation is crucial for safety and performance:

  • Placement: Install the heater at least 4 feet downstream from any fans, dampers, or elbows to ensure uniform airflow and prevent turbulence.
  • Airflow: Maintain the manufacturer's recommended minimum airflow to prevent overheating.
  • Clearances: Ensure adequate clearances from combustible materials and provide access for maintenance.

Frequent cycling can result from:

  • Insufficient Airflow: Ensure airflow meets the heater's minimum requirements.
  • Improper Placement: Installing the heater too close to fans or bends can cause airflow turbulence.
  • High Incoming Air Temperature: Elevated temperatures can trigger safety limits.

Addressing these issues can help maintain consistent heater operation.

Regular maintenance includes:

  • Annual Inspections: Check wire terminals for tightness and inspect heating elements and controls.
  • Air Filters: Regularly clean or replace filters to maintain proper airflow and prevent dust accumulation on heating elements.
  • System Checks: Ensure fans and airflow switches are functioning correctly to prevent overheating.

Yes, duct heaters can integrate with existing HVAC controls, provided the control signals are compatible. For modulating heaters, an active 0-10VDC or 4-20mA signal is typically required. Staged heaters may need low voltage signals or dry contacts for each stage. Consult the heater's specifications to ensure compatibility.

Safety features often include:

  • Thermal Cutouts: Protect against overheating by interrupting power if temperatures exceed safe limits.
  • Airflow Switches: Ensure the heater operates only when there is sufficient airflow.
  • Manual Reset Limits: Require manual intervention to reset after a high-temperature condition, preventing automatic restarts after a fault.
