QUESTIONS: Some have questions concerning the use of this type of heater. Below you will find answers to the two questions most commonly asked:
Q. How hot will this get the WVO?
A. I receive this question often, but it cannot be answered with a simple reply. There are many variables which will affect the maximum temperature reached. These include the temperature of the oil entering the heat chamber, the size and style of the heat chamber, the material the heat chamber is made out of, the flow rate of the oil through the heat chamber, and the position and setting of the thermostat used. If the glow plug and fitting are placed in a small T fitting without a thermostat the oil can go over 200 degrees F which is too hot. My tests have shown that if you get temperature of the oil to 150 to 160 degrees F just before it enters the injection pump then maximum temperature reach when injected will be close to 200 degrees F. The final temperature boost will be provided by the heat of they cylinder head and injectors themselves. Tips on chamber type, size and location will be included in my instructions.
Q. How adjustable is the thermostat control?
A. The thermostat can be adjusted from 90 degrees to 150 degrees F. That does not mean the temperature of the oil itself can only be adjusted within that range. Where and how you place the thermostat will play a huge roll in the actual temperatures of the vegetable oil. Placement and operational tips are included with my instructions.
Please note: glow plugs have proven to be an effective means of heating vegetable oil provided you do not allow the chamber to run dry of fuel. If you do the glow plug will burn out in a very short period of time. So a word to the wise if you are going to use glow plugs you have to be careful to not run out of fuel.
