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.

Heater Warranty and Return Policy

It is the customer's responsibility to carefully inspect heaters for damage before accepting delivery since heaters are usually not returnable once delivery is accepted. Obviously damaged heaters should be refused and Greenhouse Megastore customer service contacted to make arrangements for a replacement unit. 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.

Value & Quality
Color: Black/Black
Just like described works excellent. You cannot beat it for the Money 4.8 should be five stars. Adjustable coarseness is real nice too. I do a lot of barbecuing and you want a thick pepper and salt for brisket. Just real nice one Hand operation if you’re doing something so it was a salt shaker pepper shaker but this one being able to grind fresh is real nice.

Sleek, Easy to Use, and Works Perfectly!
Color: Upgrade Silver, Size: Rechargeable
I absolutely love this electric salt and pepper grinder set! The stainless steel design looks modern and elegant on my kitchen counter. They’re super easy to use — just press the button, and you get a consistent grind every time. The adjustable coarseness feature works great for everything from fine salt to coarse pepper. The built-in light is a nice touch when seasoning food at the table or over the stove. Battery life is good, and refilling is simple. Excellent value and quality — highly recommend!

Nice salt and pepper grinder set!
Color: Upgrade Silver, Size: Rechargeable
These are very nice quality. They work really well. You can adjust the coarseness as you prefer. They aren't overly loud. I got them for someone as a gift for someone and I'm going to get myself a set also because I really like them. They charge quickly. Overall, a really nice set that seems like it will last a long time.

No problems here... Great battery life and functions.
Color: Upgrade Silver, Size: Rechargeable
These things hold a charge forever.. I maybe charge them once every 3 or 4 months and use them daily. Good adjustment for coarse or fine grind. I would recommend.

Great grinders, bad recharging stand
Color: Upgrade Silver, Size: Rechargeable
The grinders work amazing and I loved them, but the stand that recharges them stoped working a little after a year.
