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 book, quite through
This was quite an in depth analysis on the subject which the author writes from his own experiences, and it seems quite obvious that he is not making any of it up. His explanations can be tedious at times, but this is in an effort to present the information as scientifically as possible, trying to answer any and all doubts and questions that would arise to the skeptical minded person. If you are interested in astral projection, I have never read a more revealing book on the subject.

Astral Projection From A Century Ago
Format: Kindle
This book is roughly a century old. With that comes a slightly different language but not one too difficult to follow. Some of the things that stuck out for me were: * The astral cable or “silver cord.” * The subjects of possession and the demonic. * The detailed suggestions for astral projection. This book could have used some editing ( there is the occasional “I” out of place) in spots but it remains very readable and helpful for understanding what astral projection is and different facets of it.

Marvelous!
This a Must Read for all OBE students and explorers. The kind of book that you can't let go of once you begin reading. The detail explanation and the descriptions are astonishing. I am amazed! It gave me a renewed interest in this discipline and I understood things that I'd given up on. What a fresh breath from a century ago... Thank you, Mr. Muldoon. I am at a loss for words to express my gratitude.

THE VERY BEST BOOK EVER WRITTEN ABOUT THE PROJECTION OF THE ASTRAL BODY!
Format: Paperback
In my opinion, Sylvan Muldoon's book continues after many decades to be the most inspiring and well written and meaningful book ever written on the out of body experience! I always suggest that anybody interested in the subject should always read this classic as being a truly honest and sincere, knowledgable guide written by the person many consider, The Father of Astral Projection.

Read Projection of the Astral Body, and Get More Restful Sleep!
Format: Paperback
Sylvan Muldoon's Projection of the Astral Body can best be described as a great eye-opener. It is highly useful for the general public-i.e. for anyone who sleeps. But it is especially helpful to those curious about what happens during sleep, and those who want to sleep more adequately. It has my highest recommendation. Charlotte E.
