Electric Unit Heaters

What are Dayton electric heaters?
Dayton electric unit heaters are typically used in areas with high ceilings and are able to heat large volume areas without the need for extensive duct systems. Dayton electric heaters have an energy efficient fan coil design to offer a maximum airflow of 3400 cfm and are ideal for continuous or intermittent use in factories, warehouses, stock rooms and service stations. These unit heaters feature an excellent pull through airflow design for even air distribution & cooler element operation and an automatic reset linear thermal protector to disconnect the heater when the normal operating temperature gets exceeded. Dayton electric heaters have totally enclosed motors with die formed, heavy gauge steel housing to withstand harsh industrial environments. They are equipped with aluminium finned, copper clad steel sheath heating element for efficient operation. Choose from a wide variety of these Dayton electric heaters, available in a maximum heating capacity of 85250 BTUh, on Raptor Supplies.

Electric Unit Heaters

Electric unit heaters are suitable for providing primary / supplementary heating in exposed areas like warehouses and factories. They are wall- or ceiling-mounted for use in downflow or horizontal heating applications and saving limited floor working spaces. These industrial unit heaters feature a forced air system to heat the air by using a heating element and a fan. They come with adjustable air outlet louvers to direct the airflow in the desired direction. These heaters have a one-piece, portable design for easy operation in remote locations & outdoor areas.
Dayton unit heaters can heat up large spaces continuously or intermittently. They are equipped with an aluminium-finned, copper-clad steel sheath heating element for excellent heat conductivity and a heavy-duty totally enclosed motor that accepts single- / three-phase power supply. The motors drive a fan with large dynamically balanced blades for channeling the heat through the unit's Venturi outlet to a desired location. The fan gets its air supply through the back side of the unit having an advanced inlet louver design for drawing cool air over the heating element. Dayton heaters also have numerous safety features like an automatic reset linear thermal protector that disconnects the unit in case of overheating.
QMark electric unit heaters have 18- / 20-gauge steel construction with a powder coated or polyester powder-coated finish for structural rigidity & abrasion resistance. Selected models of these QMark unit heaters are integrated with a 2-speed fan selector switch and a fan-only switch that helps control the air movement speed with or without the heat.


Electric unit heaters are ideal for heating large areas like factories, warehouses and garages. They are ideal for locations where central heating is not possible. However, selected models can also fit into tight spaces and ducts.


  • Electric unit heaters are used to heat up warehouses, stock rooms, service stations, factories and large exposed areas.
  • They can be suspended from walls or ceilings for reducing wastage of floor space.
  • These unit heaters use a forced air heating system containing a heating element and a fan.
  • The linear thermal protector with an automatic reset feature prevents overheating.
  • They are further integrated with adjustable louvres for controlling the directional flow of heat.
  • These unit heaters have powder-coated steel housing and an enclosed electric motor for protection against harsh industrial environments & contaminants.

Vestil IBC Series intermediate bulk container heaters

  • These adjustable wrap-around tote tank heaters are used in pharmaceutical, chemical, cosmetic and food industries for heating containers having viscous liquids.
  • They are equipped with simple modifiable straps to apply & adjust the heater easily to an existing unit.
  • These heaters are integrated with an adjustable thermometer and a built-in maximum temperature reset mechanism for allocating desired heat precisely and ensuring durability.
  • They have silicone impregnated cloth construction for excellent UV stability and to withstand temperatures ranging from 50 to 160 degrees F.

Airmaster Fan electric unit heaters

  • They have a portable, one-piece structure for easily fitting into compact spaces.
  • These Airmaster heaters are integrated with a built-in thermostat having two / three comfort heat selections for precise temperature rise.
  • They also have safety features like overheat & tip-over shut-off control and a power on indicator lamp for safe operation.
  • We also supply electric salamander heaters that have a drum type body structure with wheels for portable heating at the desired location.
  • These salamander heaters further feature finned tubular heating elements and safety screens on both the air intake and output opening enclosures.

Working Mechanism

  • After purchasing an electric unit heater with the desired airflow rating, heat & power specifications, the unit is installed on the walls or ceiling near a power source using mounting brackets.
  • Switch on the power to start the heater. Toggle the fan delay switch (available in selected models) if you want to eliminate cold drafts by letting the unit heat up first.
  • Now, the unit starts supplying heated air horizontally or with a downflow.
  • The speed of the unit can be controlled using a mechanical dial and the temperature rise / heating can be adjusted using a thermostat that is available in some electric unit heaters.

Standards and Approvals

Dayton & Airmaster Fan electric unit heaters are UL- & cUL-listed whereas the QMark heaters are UL, NEC & OSHA certified for user safety and delivering optimum performance.

Frequently Asked Questions

What to do in case of electric unit heater failure?

Assuming that the selected unit heater is the correct choice for the desired heating capacity & airflow, the first thing to check is the wiring connection & the status of fuse. Users should also clean dirt or dust accumulated on the motor, causing heating up of the motor. Motors should also be lubricated regularly for smooth operation.

What accessories are compatible with these electric unit heaters?

Raptor Supplies can deliver a wide range of accessories that fit into the electric unit heaters for ease-of-use. Thermostats are used to control the temperature of the heater either digitally or through a mechanical dial. Internal fan switch allows users to switch on only the fan during summer months. Universal wall and ceiling mounting bracket kits are used to attach these unit heaters to walls or ceiling without taking up the floor space.

What is the difference between different variants of electric heaters?

Electric heaters come in various types such as electric baseboard heaters, electric fan coil heaters, heating cables and portable electric heaters. The electric baseboard heaters install along the base of the wall to supplement the central heating system or warm a small room by itself. Electric heating cables heat up pipes, roof, and gutter systems. They are also installed under the flooring for heating the floors. The electric fan coil heaters or plenum heaters are used for heating concealed places like drop ceilings or plenum spaces. The portable electric models can be moved from one location to another using wheels or carts wherever extra heat is desired. They are also used as personal heating units in offices or receptions.

Does Raptor Supplies offer other variants of electric unit heaters?

Yes, Raptor Supplies offers various variants of electric unit heaters, namely electric baseboard heaters, electric fan coil heaters, heating cables and portable electric heaters.
