Diesel-powered heaters such as the Espar Pro-Heat and Webasto have become indispensable tools in a variety of industries, particularly for those working in harsh environments like construction, trucking, or remote job sites. These heaters provide reliable warmth in cold weather, helping to maintain a comfortable working environment while preventing engine and hydraulic fluids from freezing. This article aims to explain how these heaters work, compare the leading brands, provide troubleshooting tips, and share some helpful maintenance practices to ensure long-lasting operation.
What are Espar Pro-Heat and Webasto Diesel Heaters?
Espar Pro-Heat and Webasto are two of the most popular brands when it comes to diesel-powered heaters used in vehicles and machinery. These heaters operate by utilizing diesel fuel, which powers a combustion process that generates heat. Unlike traditional heaters, which use the engine’s coolant or a dedicated fuel source, these systems are self-contained and can operate independently of the vehicle’s engine.
These systems are often used in a variety of vehicles, from trucks and RVs to construction equipment and boats. Their purpose is to provide cabin or engine compartment heat during winter months, preventing issues like fuel freezing, maintaining comfortable working conditions, and ensuring that the vehicle or equipment can start properly in cold temperatures.
Espar Pro-Heat
Espar is known for its high-quality air and water-based heating solutions. Their Pro-Heat range is often used in heavy-duty vehicles, trucks, and machinery. The Pro-Heat units operate by drawing in cold air, passing it over a heat exchanger, and then pushing the heated air into the cabin or engine compartment. Espar systems are compact, efficient, and can be controlled remotely, making them ideal for long-haul trucks and construction equipment that operate in extreme temperatures.
Espar heaters are generally known for their reliability, durability, and quiet operation. They also offer a variety of models, from smaller units designed for personal use to larger, more robust models designed for heavy-duty applications.
Webasto
Webasto is another leading brand in the diesel heater market, known for providing solutions for both air and water heating. Their products are widely used in trucks, RVs, and boats, but also find applications in industrial machinery and off-road vehicles. Webasto heaters are highly regarded for their high efficiency and versatility, providing customizable heating solutions depending on user needs.
Webasto heaters work similarly to Espar heaters, with both systems employing a combustion chamber to generate heat. However, Webasto offers a broader range of heating options, including hot air and liquid-based heating systems, and their models are often known for their advanced features, such as integrated digital controls and more precise temperature regulation.
How Diesel Heaters Work
Both Espar and Webasto diesel heaters operate through a relatively simple process. Here’s a basic breakdown of how these systems work:

How Diesel Heaters Work
Both Espar and Webasto diesel heaters operate through a relatively simple process. Here’s a basic breakdown of how these systems work:
- Fuel Combustion: The heater draws diesel fuel from the vehicle’s fuel tank and ignites it in a combustion chamber. This combustion process generates heat.
- Heat Transfer: The heat generated by the combustion process is transferred to either air or water, depending on the system. Air-based systems will pass the heated air through a heat exchanger, while water-based systems will circulate heated coolant through the engine or cabin.
- Heat Distribution: Once heated, the air or coolant is then distributed into the cabin or engine compartment via ducts, fans, or hoses. For air-based systems, a fan helps push the warm air into the vehicle’s interior, while for water-based systems, heated coolant circulates through radiators or heat exchangers.
- Ventilation: Once the air has cooled, it is vented out of the heater. These systems are generally designed to be efficient and minimize emissions.
Diesel-powered heaters, like those from Espar and Webasto, offer several significant benefits:
- Fuel Efficiency: Diesel heaters are generally more fuel-efficient than gasoline-powered systems, providing longer run times on a smaller fuel tank. This makes them ideal for vehicles and machinery that need to operate in remote locations where refueling options may be limited.
- Remote Operation: Many modern diesel heaters can be remotely controlled, allowing users to preheat the vehicle or cabin from a distance, saving time and improving comfort before starting the workday.
- Prevents Engine Freezing: Diesel heaters are vital in preventing engine compartments from freezing in extremely cold temperatures. By circulating warm air or coolant, they ensure that critical engine components stay at an optimal temperature.
- Improved Comfort: These heaters create a comfortable environment for workers who need to spend time in cold, outdoor conditions. Whether it’s for truck drivers, construction workers, or marine operators, staying warm in cold conditions is critical for both productivity and safety.
- Durability: Both Espar and Webasto heaters are designed for longevity and reliability in demanding environments. Their high-quality construction means they are built to withstand harsh conditions and continuous operation.
While diesel heaters are reliable, they may encounter issues over time. Below are some of the common problems and troubleshooting tips:
1. Heater Won’t Start
- Fuel Supply Issue: Ensure that there is sufficient fuel in the tank and that the fuel line is not clogged.
- Air in the Fuel Line: Air trapped in the fuel line can prevent the heater from starting. Bleeding the fuel system may resolve this issue.
- Glow Plug Failure: The glow plug, which ignites the fuel, may have failed. Check the glow plug for damage and replace it if necessary.
- Fuel or Combustion Issues: If the heater is blowing cold air, it could be due to an issue with the combustion process. Check the fuel filter for blockages or contamination. Also, ensure that the combustion chamber is clean and free of soot or carbon buildup.
- Fan Malfunction: If the fan is not running correctly, it may not be circulating the heated air properly. Check the fan motor and replace any damaged components.
- Blocked Air Intake or Exhaust: If the heater is making unusual or loud noises, it may be due to a blocked air intake or exhaust. Check for any obstructions and clear them out.
- Loose Components: Vibration or rattling noises could be due to loose components in the heater. Tighten any loose bolts or fasteners to reduce noise.
- Overheating: If the heater is shutting down unexpectedly, it could be a result of overheating. Ensure that the system’s heat exchanger and fan are functioning properly.
- Faulty Thermostat: The thermostat may be malfunctioning, causing the system to turn off before the cabin reaches the desired temperature.
Proper maintenance is crucial to ensure that your diesel heater continues to perform efficiently for years. Here are some essential maintenance tips:
- Regular Cleaning: Clean the combustion chamber, fuel filter, and air intake regularly to prevent carbon buildup and ensure optimal combustion.
- Fuel System Maintenance: Check for leaks or cracks in the fuel lines, and replace the fuel filter as needed. Always use clean, high-quality fuel to prevent clogging.
- Check Electrical Connections: Inspect the electrical connections, including the battery and wiring, for wear and corrosion. Replace damaged wires or connectors to maintain efficient operation.
- Service the Glow Plug: Periodically check the glow plug for wear and replace it if necessary to ensure reliable ignition.
- Inspect the Exhaust System: Check for obstructions in the exhaust system and clean it to ensure that the heater’s gases are vented safely.
