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

Model PDP Power-Vented Unit Heaters: The PDP (propeller) High Efficiency II gas-fired unit heaters feature a blower-powered vent exhaust. This vent forces heater exhaust fumes outside of the heated structure, and allows the heater to be vented vertically or horizontally. Horizontal venting prevents heat from escaping out of the vent pipe when the heater is not running, which is especially important in greenhouses.

Standard Features

  • 83% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and power exhauster.
  • Power exhaust that can be rotated 180 degrees.
  • 100% shut-off, intermittent pilot-ignition system with continuous retry.
  • Field convertable from natural to propane gas.
  • Safety pressure-switch to assure safe venting conditions.
  • Designed to use the smallest diameter vent pipe possible.
  • "Wing" screws so that the bottom pan can be dropped without a screwdriver.
  • Certified to 0.5" W.C. external static pressure.
  • A level hanging mechanism for easy field adjustments.

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.

Not invincible but good value
Color: 5pack, Size: Large
Great value for the money. We have 3 dogs and they are pretty strong chewers. They lasted a few months but ultimately succumbed to their inevitable doom. They arrived well packaged and with no unusual odors.

One of the best indestructible dog toys we've bought
Color: 5pack, Size: Large
So we adopted a pup in December and she tears up everything! I mean, Everything! My CPAP, garden hoses, trucks seat belt and backup camera wiring. Every single dog toy with stuffing, dismantle them in minutes. So many dog toys say they are are tear proof. nope! We have tons of stuffing all over our 5 acres. Hen m wife bought these. Beside the bones she bought, these are the only things she can't seem to destroy and she loves them!!!!

BEST Dog Toys EVER! JRT approved
Color: 5pack, Size: Large
🌟 🌟 🌟 🌟 🌟 for these toys! We have terriers who have NEVER met a toy they couldn't destroy... until now. We've had them over a week an all 5 are still intact, crinkly, and squeakers squeaking - and they're played with constantly! When I tell you I've never, in all my years of JRT ownership and rescue, had a toy last 24 hours, much less a WEEK? Well, lots of you will know how astonishing that is! We've currently got 5 dogs (2 fosters, anyone looking for a project?) so the package size is perfect. Get 'em.
