Lecture on Diesel Heaters Review

Introduction

• Review of two diesel heaters: 5 kilowatt and 8 kilowatt.
• Purpose: Assess the value, differences, and safety concerns.
• Discussion topics: Unit differences, myths, burning used oil, cost-effectiveness, safety.

Diesel Heater Components

• Simple unit design:
  • Diesel burner with a glow plug.
  • Fuel tank and pump.
  • Electronics to run.
  • Requires a 12-volt battery.
• Heating method: High flash point of diesel; uses glow plug to ignite.
• Fuel pump operates at a 45-degree angle.
• Construction:
  • Made of plastic casing around burn chamber.
  • Intake and exhaust needed.
  • Fuel comes in, heats fins, air blows out.
• Serviceability: Replaceable gaskets, glow plugs, fans.

Comparison Between 5kW and 8kW Units

• Both units look and perform identically.
• Only noticeable difference: color of certain components.
• Speculation that difference might be a marketing gimmick.
• Everything is serviceable and interchangeable.

Fuel Options and Considerations

• Designed to run on diesel:
  • Clear diesel vs dyed diesel (cheaper, off-road use).
  • Risks of water in diesel leading to rust.
• Alternative fuels:
  • Hydraulic oil is an option; thinner, less carbon buildup.
  • Used engine oil not ideal due to carbon and additives.
  • Mixed fuels (diesel with used oil) can help.

Safety and Maintenance

• Ensure pump and glow plug are properly tightened.
• Gain free heat by running used oil, but may violate regulations.
  • Used oil burners can provide heat but require maintenance.
• Risks of clogging from carbon buildup.
• Importance of filtering and warming oil before use.

Installation and Usage

• Installed in a 20-foot shipping container.
• Setup includes exhaust through a cast iron radiator for heat retention.
• Duration and process for heating space discussed.
• Bleeding the heater system for air removal.

Final Evaluation

• Diesel heaters are cost-effective and provide efficient heating.
• Mixed opinions on using alternatives like used oil.
• Value for $100; benefits of heat sink for long-lasting heat.
• Emphasis on safety, legality, and insurance concerns.

Conclusion

• Recommendation: Worth the investment for personal and workspace heating.
• Caution advised for using non-recommended fuels.
