Model HER Horizontal Delivery Heaters: Recommended for use in greenhouses or buildings where ceilings are low and with few obstructions. Units are equipped with air deflector blades that can be adjusted to lengthen or shorten heat throw as well as to direct heated air up or down. Units are normally placed around the perimeter of the structure so that the air stream from each heater "wipes" the wall to produce a blanket of warm air along the building's outside walls where heat loss is greatest.

Standard Features

Low Installation Cost
Terminal blocks are supplied to facilitate connection of power supply and control wiring. Heaters are lightweight and usually require no special reinforcement to suspend them. Easy to install - just hang the heater, connect to power supply, controls and thermostat and it is ready to operate.

Heating elements are resistant to thermal shock and vibration for a long, trouble-free life.

Application Flexibility
Equipped with adjustable horizontally positioned air deflector blades (HER units) to allow complete control over the air discharged by the unit.

Quiet Operation
Fans are accurately balanced to move air quietly. Motors mounted to fan guards utilize rubber vibration absorbing material for quieter operation.

Low Maintenance
Motors are totally enclosed, permanently lubricated, and thermally protected. Electrical contactors, fuses and transformers are all safety enclosed in control compartments.

Easy to Service
Fan and motor are exposed for easy removal without lowering the unit heater. Hinged bottom panel permits full access to controls.

Once delivery is accepted Greenhouse Megastore will gladly provide replacement parts under the manufacturer's warranty to repair damaged or defective heaters; however this warranty does not include any labor costs associated with installing these parts. Warranty issues should be diagnosed by a certified HVAC technician since parts deemed not to be defective by the manufacturer are not available for credit back to the customer. Specific warranty policies vary by manufacturer but typically cover replacement parts as indicated above up to one year after purchase. Please contact Greenhouse Megastore customer service if you have any questions about the warranty for your specific heater.

  • Built to last
    i purchased the HER100 240-1 phase unit, installed it Nov/2011 here it is Nov/2020 my garage is 35'x60' with 6" insulated walls, 4 garage doors, a 6/12 roof with 1/2" plywood with Metal standing seam roof no insulation, in central Missouri, i leave it on all winter set at about 55* it cycles on and off on sunny days, even when its 20* outside. if i turn it off, then it takes 4/5 hours to heat it up when its really cold out, thats why i leave it run all winter, it keeps the garage 55* no problem, but in 9 years no problems, fairly quiet too. i bought my unit, with the unit mounted thermostat kit. i have it mounted from a 9' ceiling, so i can reach the thermostat knob standing on the floor. made in usa. too.
  • Appears to be a solid product
    Incredible build quality. The craftsmanship and detail that went into the electrical components and connectors is impressive. Each piece of wire is terminated and screwed in. The solid copper bus for the heating elements blew me away. The fan blades have been balanced. It has not been cold enough yet here in Texas to give it a proper shakedown, but it worked perfectly once I set the thermostat high enough. Not noisy.
