Zero start

Types of Zero Start

A zero start is commonly used in cold weather to heat the engine block, oil pan, and coolant. This allows the vehicle to start quickly and run smoothly. There are different types of zero-start options:

• Engine Block Heaters

  Engine block heaters are installed on or in the engine block. They warm the coolant inside the engine to about 60 degrees Fahrenheit (15 degrees Celsius) before starting the vehicle. These heaters use 400 to 1200 watts of power to operate.

• Oil Pan Heaters

  Oil pan heaters are installed on the vehicle's oil pan. They heat the engine oil to make it thinner before starting. This allows the oil to circulate through the engine faster. Oil pan heaters typically consume 100 to 300 watts of power.

• Magnetic Block Heaters

  Magnetic block heaters are external heaters placed on the vehicle's engine block. They use magnets to attach to the engine. Like engine block heaters, these magnetic heaters warm the coolant inside the engine. They typically use 100 to 300 watts of power.

• Battery Warmers

  Battery warmers are heaters placed around the vehicle's battery. They keep the battery warm to ensure it has enough power to start the vehicle, even in cold weather. These heaters usually consume 40 to 100 watts of power.

• Fuel Line Heaters

  Fuel line heaters are installed on or near the vehicle's fuel lines. They heat the fuel before it enters the engine. Heating the fuel helps prevent it from gelling or thickening in extremely cold temperatures. These heaters typically use 40 to 100 watts of power.

• Windshield Ice Scrapers

  Ice scrapers are electrically heated devices used to remove ice and frost from windshields. They usually connect to the vehicle's 12V power outlet or another external power source. Ice scrapers typically consume 30 to 150 watts of power, depending on their size and heating capabilities.

Specification & Maintenance of Zero Start

The specifications for zero-start devices can differ due to various factors, such as the manufacturer, model, and intended use. Nonetheless, here are some standard specifications for these devices:

• Power Supply

  Zero-start devices usually require a low-power supply to initially activate the control circuit. This power supply can be 120V or 240V AC, depending on the model.

• Voltage Control

  These devices control the voltage supplied to the load or the device being controlled. The voltage levels can differ based on the model but typically range between 0-240V AC.

• Current Rating

  The current rating indicates the maximum current the zero-start device can control. This can differ based on the specific model but usually ranges from 10A to 100A.

• Control Type

  Zero-start devices use various control techniques to manage the connected load. This can involve proportional control (PID), on/off control, or timing control.

• Temperature Control

  In some zero-start devices, particularly those used for industrial processes, there may be integrated temperature control features. This can involve built-in temperature sensors and controllers to manage and monitor temperature settings.

Maintaining these zero-start devices is essential to ensure they function effectively and have a long lifespan. The following are some general maintenance tips:

• Regular Inspection

  Regularly inspect the zero-start devices to identify any wear, damage, or corrosion signs. Conduct a thorough visual inspection and look for anything unusual.

• Cleaning

  Clean the zero-start devices regularly to eliminate dust, dirt, and other contaminants. Use a damp cloth or soft brush to clean the outer surfaces. Do not use abrasive materials or harsh cleaners that can damage the devices' surfaces.

• Connection and Cable Inspection

  Check all connections and cables related to the zero-start devices. Ensure that they are secure and undamaged. Replace any worn-out or damaged cables to avoid affecting the devices' performance.

• Control Circuit Maintenance

  If the zero-start device has a control circuit, ensure that it is maintained well. Check the control circuit components such as timers, relays, and sensors, and replace any damaged or worn-out components.

• Follow Manufacturer's Instructions

  For specific maintenance procedures and recommendations, refer to the user's manual or maintenance guide provided by the zero-start device manufacturer. Follow their instructions to maintain the devices properly.

How to choose Zero Start

There are several factors to consider when choosing a Zero Start model. These include:

• Application

  Consider how and where the vehicle will be used. A construction worker driving a large pickup truck may need a heavy-duty zero-start heater. In contrast, a compact car used mainly for commuting in a mild climate may require a less powerful model.

• Vehicle Size and Type

  Generally, larger and heavier vehicles require more powerful heaters to warm them up effectively. Also, different vehicle types (sedans, trucks, SUVs) have different heating needs. For example, a zero-start heater for a diesel truck will be more powerful than one installed in a gasoline-powered compact car.

• Fuel Type

  Zero-start heaters can be powered by gasoline, diesel, or electricity (from the vehicle's battery). Diesel heaters tend to be more powerful and fuel-efficient, making them suitable for larger vehicles. Gasoline heaters are more commonly used and less expensive than diesel models. Electric heaters are the least powerful but sufficient for small vehicles.

• Climate Considerations

  Vehicles used in extremely cold regions require more powerful zero-start heaters than those used in areas with mild winters. Additionally, features like adjustable thermostats and timers can be beneficial in colder climates, allowing for better temperature control and preheating flexibility.

• Budget

  Zero-start heaters can range in price based on factors such as size, type, and additional features. It's important to consider both the initial cost and any potential installation expenses when selecting a heater that fits within the planned budget.

• Installation

  Some zero-start heaters require professional installation, which can add to the overall cost. Others may be more straightforward to install as a DIY project. Consider the ease of installation and whether professional assistance will be needed.

How to DIY and Replace Zero Start

Below are the steps for installing a Zero Start heater:

• Choose the Right Heater

  Select a heater that is suitable for the vehicle. It must be compatible with the vehicle's engine size and type.

• Gather Tools

  One should have all the necessary tools required for installation. This might include wrenches, screwdrivers, pliers, drills, and mounting hardware.

• Read Instructions

  Study the installation manual provided by the manufacturer. It is very important as it gives detailed steps for a specific model.

• Select Installation Location

  Find a suitable place to install the heater. It should be away from moving parts and with proper ventilation. Also, the location must be accessible for future maintenance.

• Prepare the Installation Site

  Clean the area where the heater will be mounted. Also, check that the mounting surface is free from rust and debris.

• Mount the Heater

  Follow the manufacturer's instructions to mount the heater. Use the provided mounting hardware and ensure it is securely fastened.

• Connect Electrical Wiring

  If the heater requires electrical connections, follow the wiring diagram in the manual. Connect the wires to the appropriate terminals and secure them.

• Connect to Cooling System

  One should connect the heater to the vehicle's cooling system. This typically involves connecting hoses from the heater to the engine's coolant passages.

• Check for Leaks

  After making all the connections, check for any leaks. Run the vehicle and inspect all hoses and connections for signs of coolant leakage.

• Test Operation

  Start the vehicle and test the heater's operation. Ensure it is functioning correctly and providing the desired heating.

• Final Inspection

  Go through all the steps once more. Ensure that everything is in place and that the heater is working properly.

Q and A

Q1: Can one convert a traditional car battery to a zero-start battery?
