Types of Engine Heater

An engine heater is a device used to preheat or maintain the temperature of an engine. It can be an electric engine heater, a coolant heater, or a diesel-fired heater. Here are some common types of engine heaters:

  • Coolant engine heaters: Coolant engine heaters, also known as engine coolant heaters or liquid heaters, are electric engine heaters that preheat the engine's coolant. They are connected to the engine's cooling system. By preheating the coolant, they ensure the engine starts smoothly. Furthermore, they reduce the wear and tear of the engine. Coolant engine heaters are perfect for extreme cold conditions or for engines that are not used often.
  • Oil pan heaters: An oil pan heater is a device that is attached to the bottom of the engine's oil pan. It uses an electric heating element to heat the oil in the pan. The heated oil becomes thinner and pours more easily into the engine. Additionally, the engine's cold start is reduced, preventing wear and tear. Oil pan heaters are ideal for extreme cold conditions.
  • Block heaters: Block heaters are electric engine heaters that are preinstalled in the engine of a vehicle. They heat the entire engine block and maintain a warm temperature. The heated block ensures the engine starts quickly, regardless of how cold the weather is. Block heaters are perfect for extremely cold environments.
  • Immersion engine heaters: Immersion engine heaters are diesel engine heaters that are immersed in the engine's fuel tank. They heat the fuel directly. This ensures that the diesel engine is heated quickly and efficiently. Immersion engine heaters are essential in cold weather or when dealing with diesel engines that are hard to start.
  • Air heaters: Air heaters are engine heaters designed to heat the air going into the engine. They are more commonly used for diesel engines. Air heaters use the heat generated by the engine to warm the air before it enters the engine. This ensures the engine starts better in cold weather and also reduces emissions.

Specifications and Maintenance of Engine Heaters

Normally, engine block warmers are available in various specifications. Here are a few common ones to keep an eye out for:

  • Power rating: The power rating of an engine block heater tells the amount of power it uses to operate. This is measured in watts. Normally, block heaters have power ratings of 400 to 2000 watts. They are designed for different applications. For instance, a 1000-watt engine block heater is ideal for heavy-duty vehicles that have larger engines. It will heat the engine quickly and maintain the temperature to avoid freezing. Vehicles with smaller engines, such as compact cars, are compatible with block heaters that have lower power ratings, like 400 watts.
  • Voltage: Engine block heaters are designed to operate with standard electrical systems in various regions. Most heaters have voltage ratings of 120V or 240V. The voltage of the heater should match that of the electrical outlet where it will be plugged in.
  • Heating element: The heating element is a key component of the engine block heater. It is responsible for converting electrical energy into heat. Common materials used for heating elements include aluminum and PTC. Aluminum is a good heat conductor that warms up quickly. PTC heating elements operate at stable temperatures. They regulate the heat emitted to prevent overheating.
  • Cord length: The length of the power cord for the engine block heater can vary depending on the design. Long cords, like 6 to 10 feet, enable flexibility during use and ensure the outlet is reached from the engine. Some heaters are equipped with cold-weather-resistant cords. They stay flexible and won't crack in extreme temperatures.

Engine block heaters are designed for minimal maintenance. Here's how to keep them in top shape:

  • Regular inspection: Visual inspection of the engine block heater and its components is important. Look for signs of damage like frayed cords, cracks in the heating element, and loose connections. Attend to any issues noted during inspection.
  • Keep it clean: Wipe the engine block heater with a cloth to remove dirt and dust. Clean the engine surface with a soft brush to prevent debris from getting into the engine compartment.
  • Check electrical connections: Make sure the cords are plugged into the outlet and heater properly. Loose connections can lead to malfunction or accidents like fires. Tighten any loose plugs and replace any damaged cords.
  • Inspect the heating element: With the engine block heater unplugged, check the heating element for signs of damage or wear. Look out for burn marks. If it seems faulty, get a professional to replace it.
  • Check for proper function: Before the cold weather begins, check that the block heater is functioning optimally. Plug it in for about an hour and touch the engine to confirm that it is heating up. If it fails to warm up, consult a mechanic.
  • Follow manufacturer instructions: Different types of engine block heaters may have specific care requirements. Follow the user manual’s advice for cleaning and storing the engine block heater.

How to Choose and Engine Heater

  • Consider the Climate
  • When choosing an engine block heater, it’s important to consider the climate of the region in which the vehicle is used. Cold regions require a powerful heater to generate heat and keep the engine warm. The temperature of the region must be taken into account.

  • Vehicle Type and Condition
  • When selecting an engine block heater, the type of vehicle and its condition are important factors to consider. Large vehicles like trucks and commercial vehicles dissipate more heat, so the engine heater should have high power. For older vehicles, an engine heater would be required as the engine heating system may be worn out. New vehicles usually come with an engine block heater.

  • Heater Type
  • There are different types of engine block heaters with various power and features. The most common one is the electric heater that provides a direct and constant heat source. Another one is the engine coolant heater that circulates hot water through the engine block. Dipstick engine heaters are plugged into the oil dipstick and are less effective than other options.
