It is recommended to wire the heater to a battery bank separate from the vehicle starter battery
It is recommended to wire an Espar bunk heater to a battery bank separate from the vehicle's starter battery for several reasons. Firstly, by using a dedicated battery bank, you can ensure that the heater has a consistent and stable power source, which is crucial for optimal performance and efficiency. A separate battery bank eliminates the risk of overloading the vehicle's starter battery and prevents potential issues with voltage drops or power interruptions, ensuring the heater operates effectively and consistently.
Additionally, wiring the heater to a separate battery bank allows for better power management and can extend the lifespan of both the heater and the vehicle's electrical system. By isolating the power draw of the heater, you avoid placing excessive strain on the vehicle's starter battery, which is critical for starting the engine and powering essential electrical components. This separation ensures that the starter battery maintains sufficient charge, especially during cold weather when battery performance can be compromised.
Another advantage of using a separate battery bank is the ability to customize and optimize the power setup for the heater. You can select a battery type and capacity specifically suited to the power requirements of the Espar bunk heater, ensuring it receives the correct voltage and amperage. This setup also provides flexibility in terms of installation location, as you can position the heater in the most convenient and efficient location without being limited by the vehicle's existing electrical layout.
Finally, safety is a key consideration. By wiring the heater to a separate battery bank, you reduce the risk of electrical issues or faults affecting other critical vehicle systems. In the event of a malfunction or short circuit, the impact is isolated, and you avoid potential damage to sensitive components or critical functions. This setup also simplifies troubleshooting and maintenance, as the dedicated battery bank allows for easier diagnosis and repair without interfering with the vehicle's primary electrical systems.
Overall, wiring an Espar bunk heater to a separate battery bank offers numerous benefits, including improved performance, extended battery life, enhanced safety, and optimized power management. By providing a dedicated and stable power source, you can ensure the heater operates efficiently and reliably while also protecting the vehicle's electrical systems and maintaining their overall performance and integrity. This setup is a prudent measure to ensure the heater functions as intended and minimizes potential issues or conflicts with the vehicle's primary electrical systems.

The heater is designed to work best at lower altitudes
The Espar Airtronic heater is a compact and easy-to-install heating system that runs on both electricity and diesel fuel. It is highly efficient and saves a lot of diesel fuel that would otherwise be used by drivers idling for heat.
The Espar heater is designed and manufactured at a facility below 1,000 feet in altitude. As a result, it performs optimally at lower altitudes due to the oxygen-to-fuel ratio being closer to the ratio originally set by the manufacturer. This ratio is crucial, as any deviation from the perfect ratio can lead to the production of carbon soot, which can clog the heater and cause ignition issues.
The original models of the Espar heater, the D2 and B4, were designed to work effectively at altitudes up to 4,500 feet. However, to accommodate users at higher altitudes, the company introduced new models, the D2L and B4L, which are claimed to function up to 9,500 feet in altitude.
Espar has also developed a high-altitude kit that enables their heaters to operate at altitudes exceeding 3,000 meters (10,000 feet) above sea level. This kit enhances the system's adaptability and ensures its performance in various environments.
The heater's performance at lower altitudes is a result of its thoughtful design and manufacturing process, ensuring that users in these regions can benefit from efficient and reliable heating.
