Electric Unit Heaters

Electric unit heaters provide fan-forced electric heat for commercial, industrial, and other spaces where directed airflow is needed. Common uses represented in this category include factories, stores, warehouses, public buildings, workshops, garages, exposed areas, and locations needing supplemental heat or freeze prevention. Available units may be suspended, wall mounted, or ceiling mounted, with discharge arrangements that help position heat across or down into the intended area.

Use Cases

Heat work and commercial spaces

These heaters are represented for factories, stores, warehouses, public buildings, workshops, garages, and exposed spaces. Some models are also identified for supplemental heat or freeze prevention.

How to Choose

Match power and output first

Confirm the available voltage and phase before comparing output. Options represented include 208V, 240V, and 480V units, with single-phase, three-phase, or either single- or three-phase configurations.

Applications

Plan airflow around the layout

Choose horizontal discharge for heat directed across a work area, or select a model with horizontal and vertical discharge options when the installation calls for greater airflow-placement flexibility.

Additional Info

Compare control and access features

Depending on the unit, features may include built-in or factory-installed controls, adjustable louvers, hinged access doors, fan delay or override, and automatic-reset overheat protection.

3,300W–30,000WOutput range represented

Electrical and heat-output planning

Verify the installation’s electrical requirements

Electric unit heaters in this selection are offered at several output and power configurations. Matching these details to the installation is a primary comparison step.

  • Heat outputs represented range from 3,300W to 30,000W.
  • Selectable-output models include 3,750/5,000W, 5,000/3,700W, 10,000/7,500W, and 10,000W or 7,500W operation.
  • Available electrical configurations include 208V, 240V, 208/240V, and 480V.
  • Phase options represented include single-phase, three-phase, and certain 208V models supporting either single- or three-phase operation.
Mounting and airflow planning

Select discharge direction for the space

Airflow direction and mounting style affect how heat is positioned. Several heaters are designed for suspended installation, while certain models include brackets for wall or ceiling mounting.

  • Horizontal-discharge units direct heated air across the intended area.
  • Select models support either horizontal or vertical discharge installation.
  • Adjustable louvers are available across many represented models; certain units adjust airflow up to 15° from straight horizontal.
  • Represented airflow ratings include up to 400 CFM on one 5 kW unit and 700 CFM on one 10,000/7,500W unit.
Controls and operating features

Compare access, protection, and fan operation

Look at the features that support the intended installation and maintenance approach. Control access, temperature control, thermal protection, and residual-heat management vary by model.

  • Some units include a built-in thermostat, while one 10 kW model includes a disconnect switch, 24VAC transformer, and single-stage thermostat.
  • Hinged or hinged-latched doors provide access to wiring or controls on several units.
  • Automatic-reset limits, thermal cutouts, and thermal overload protection are represented for overheat protection.
  • Fan override or fan-delay features on select models help purge or dissipate residual heat during shutdown.
