Freight Savings
For large heater orders over $10,000, freight savings are available by contacting our sales team at 1-888-281-9337.

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.

Dependability
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.

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.

Surface Fabric is very durable
Size: Small, Color: Hot Pink
Surface Fabric is very durable, but the squeaker didn't last two months. I have urged the manufacturer to find a strong more durable squeaker for their product. My dogs really enoys it when the speaker works. One of his 3 work. I have just bought two more he likes them so much. He takes it to bed every night to catch it once or twice before sleeping. Also loves to catch it a few times during the day.

Best. Toy. Ever. For My Superchewer!
Size: Large, Color: Skinny Green, Size: Large, Color: Skinny Green
Best toy ever! My dog destroys toys. Usually within about 15 minutes, she has de-squeakered and defluffed them. By the second day, she has tug-of-war-ed them to shreds. From the time we got this adorable dragon out of the package, she LOVED it. She set to work. It’s been a week, and while she has dewinged him, he lost his squeaker after a few days, and he looks a bit rough, he’s still in one piece! And, we’ve had HOURS of tug-of-war with minimal rips! She’s obsessed 😍 I ordered two more today. We’ve finally found the perfect toy for my baby!

My 90 lb. Pitbull's All-Time Fave Toy
Size: Large, Color: Coral, Size: Large, Color: Coral
I ordered a plethora of new toys for Bruce to keep him occupied while I am working remotely from home. Poor guy gets so bored while I'm stuck in front of my computer 8+ hours a day. All the other toys are animated, but this one is just a big floppy chewy squeaky toy. Bruce quickly lost interest in all the other chirping, hopping, and twirling toys and fell in love with "Diny". When I opened Diny and gave it to Bruce, he had the elated and surprised look of a 3 yr old at Christmas. And he stayed that happy for hours, and then each time he picked up Diny to play. Diny became his go-to toy over all others (and there are many!). It is well made out of durable fabric, and they did not stuff it full of kapoc (I hate kapoc in dogs toys!). And it is delightfully low-tech. Normally he tears a squeaky toy apart as soon as he can isolate the squeaky mechanism. But cleverly, the squeaky box is loose in the long belly so it moves from one end to the other as the toy is handled. That made it difficult for Bruce to locate it. The toy remained in good condition for 2 weeks of near constant attention by Bruce. But yesterday he zeroed in on the squeaky box and ripped Diny to shreds. I was sad to see Diny go so soon. But boy-howdy was Bruce happy with it. I'm gonna buy another because we liked it so much. And so did I : )

This is one “under the radar” gem!!
Size: Large, Color: Coral
This is one “under the radar” gem!! Very strong internal squeaker and way tougher than it looks. My big 125lb Shepard-Husky mix gave it heck, then made it his new buddy. He’ll occasionally give it the business but on the whole, it’s surprisingly tough and my big boy loves it. Nice price!!

Cute but small
Size: Large, Color: Skinny Green
Cute stuffy and has not yet ripped. While my dogs plays with it, the toy is a bit small for him. For reference he is 120lbs.
