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.

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.

Works great. Perfect position
Grip and charging are great. I like the position because it doesn't block my view or the vents

Great design. Love it.
I have been using this charger for several months now. I think the design is fantastic. I've seen other reviews which question the reliability of it. My experience has been the opposite. I have a folding phone so it's not light. The connection to the dash has remained intact without fail. I am careful when removing the phone. I don't just yank it off. It charges as it should. The magnetic force is what I expected. Holds my phone with no issues or concerns it could fail and drop the phone. It's super convenient to have this integrated design. My dash is already occupied with a portable android auto unit. My 4Runner is older and did not have that feature. Again, this is plastic. Handle it with some care and I don't see anyone having issues with breaking. It has worked out great for me. Recommend.

Great mount / Terrible charge rate
Love the mount. Easy to install and with a small piece of double sided tape under the top edge, it’s very secure… The magnetic mount is strong enough to hold an iPhone max (at least mine). The charging ability is where it falls short *BAD! It will charge but, barely.. If you’re using maps, making calls, etc.. the phone continues to drain at an alarming rate…

Not suitable if you have a silicone case.
I'm waiting for delivery of new phone case, as the silicone one I have on my phone will not hold onto the magnet provided for this holder. Installation was a snap and I love how it looks in my car. Cost seems fair for the product. Fingers crossed that it will work fine once I get a new case.

Charger portion stopped working twice now
Works well until it doesn't. Was excited to get the phone mount off the car vent but I have gone through one replacement already and now I'm past the point to completely return it. Twice now the charging portion has failed. The first one stopped lighting up completely with in about a week and now this one just constantly flashes and no longer charges after another few weeks. I have tried different cords and outlets in my car with no success. The magnet portion however is strong and does hold the phone well.
