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

  • 80% 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.

Good
Style: Popcorn
I purchased this as a gift. The dog’s on the smaller end, and I wanted to get something not too big so the pup can bite and play with it. These have squeakers inside. It is not sturdy, though. The dog was able to tear one popcorn apart under one hour. I was not amused, but people said that’s just how the toys should work. Little fella loved this right out of the gift bag. The pup seemed happy, hence 5 starts. Made me happy for a bit as well.
