Espar Airtronic heaters are efficient, consuming 0.1-0.3 gallons per hour
Espar heaters are designed to keep drivers warm while reducing fuel costs. The Espar Airtronic heater is a good complementary heating product that consumes very little fuel—only between 0.1 and 0.3 gallons per hour. This is because the Espar Airtronic is an internal combustion system that pumps fuel from the vehicle's tank to the heater, where it is ignited using a glow pin. The combustion air and exhaust fumes are routed in and out through the floor of your van.
The Espar Airtronic D2 heater uses both electric power and fuel to operate, heating sleeper cabs well and saving a lot of diesel fuel that a driver would otherwise use by idling for heat. Diesel is more energy-dense than propane, meaning it takes less fuel to heat your van. This heater can run for 24 hours on just one gallon of diesel, which is excellent in terms of consumption. The Espar Heater is a dry fuel source, meaning it won't cause moisture to build up inside the van. Propane, on the other hand, is known to be a moist heat source, leading to the risk of condensation within the van.
The Espar Airtronic heater is compact, easy to install, and very efficient. It can be installed in any place with clear access to the floor of the van from under the van. The latest version of the Espar Airtronic heater is the AS3-D2L Diesel heater, which features a quieter fuel pump, better diagnostics features, and a 5000-hour life expectancy. The Espar D2 heater is a great solution if you don't want to carry additional propane to run a heater. It is a common heater, so any truck mechanic or service station can usually help service it.
The fuel consumption of the Espar heater will depend on the model of the heater and the power level at which it is running. For example, the ESPAR Hydronic D5 Sprinter heater uses 0.62 litres/hour (0.16 gallons/hour), while the ESPAR D2 heater consumes 0.10 litres/hour on "Low" and 0.28 litres/hour on "Power". The Espar unit is one of the larger ones rated at ~60,000 BTU, with a conversion of 0.66 gallons/hour.

Espar heaters use less fuel than APUs, and save diesel by avoiding idling
Espar heaters are an internal combustion system that pumps fuel from a vehicle's tank to the heater, where it is ignited using a glow pin. They require a 12v power source capable of providing up to 18 amps at start-up.
The Espar Airtronic D2 heater, in particular, has been noted to use both electric power and diesel fuel to operate. It is a popular heater for van conversions as it provides a single fuel source, eliminating the need to carry additional propane. The heater is designed to stop drawing fuel when the tank drops below a quarter full, preventing users from running out of fuel.
The Espar heater is also known to be more fuel-efficient than Auxiliary Power Units (APUs). According to a user, the Espar heater uses about half as much fuel as an APU, if not less. This claim is supported by another user's calculations, which estimate that an APU consumes 4 hours per gallon, while the Espar heater consumes 12 hours per gallon.
Additionally, the Espar heater helps save diesel fuel by avoiding idling. This not only reduces fuel costs but also helps fleets comply with anti-idle laws and emissions requirements in different states.

Espar D2 heaters are dry fuel sources, so no moisture builds up
The Espar Airtronic D2 heater uses both electricity and diesel fuel to operate. It is an internal combustion system that pumps fuel from the vehicle's tank to the heater, where it is ignited using a glow pin. This heater is designed to save fuel, as it stops drawing diesel when the fuel tank gets a little below a quarter full. Diesel is also more energy-dense than propane, meaning it takes less fuel to heat your van. For example, the Espar D2 heater can run for 24 hours on just one gallon of diesel.
The Espar D2 heater is a dry fuel source, so no moisture builds up. This is in contrast to propane, which is a moist heat source that can cause condensation within the van. The Espar D2 heater is also designed to work best at lower altitudes, as the oxygen-to-fuel ratio is closer to the ratio originally set by the manufacturer. The original model worked up to 4,500 feet, but newer models can work at altitudes of up to 9,500 or even 9,800 feet.
The Espar D2 heater is a popular choice for van conversions due to its compact size and ease of installation. It can be mounted anywhere in the vehicle, and the air can be ducted to wherever heat is desired. It also has a timer and is programmable according to the user's preferences.

Espar heaters are designed for lower altitudes, where oxygen-fuel ratios are optimal
The Espar Airtronic D2 heater uses both electricity and diesel fuel to operate. This heater is designed to save diesel fuel by preventing idling for heat. The heater is also known to be economical, saving fleets a significant amount in operating costs.
The Espar heater requires a 12v power source capable of providing up to 18 amps at start-up. It is recommended that the heater be wired into a separate battery bank with a capacity of at least 100ah lithium or 200ah AGM.
Espar heaters are internal combustion systems. They require three things to run: electricity, fuel, and oxygen. The system pumps fuel from the vehicle's tank to the heater, where it is ignited using a glow pin. As the altitude changes, the amount of oxygen in the air changes, affecting the fuel-oxygen ratio. Therefore, Espar heaters are designed to work optimally at lower altitudes, where the oxygen-fuel ratio is closer to the ratio set by the manufacturer.
The original Espar models (D2 and B4) worked up to 4,500 feet in altitude. However, newer models, such as the D2L and B4L, have been designed to work at higher altitudes of up to 9,500 feet. These newer models feature integrated high-altitude adjustment, allowing operation at even higher altitudes of up to 9,800 feet.
It is important to note that as the altitude increases, the risk of carbon soot build-up in the heater also increases. This is due to the change in oxygen concentration, which affects the fuel-oxygen ratio. Therefore, Espar recommends using their heaters at altitudes below 6,500 feet and servicing them regularly to clear any soot build-up.

Espar heaters can be installed anywhere with clear access to the van's floor
The Espar Airtronic D2 heater is a popular choice for van conversions. It is compact, easy to install, and can be hidden in cabinets or under the bunk. It is also programmable and comes with a timer. The heater can be installed in any place with clear access to the van's floor. This is usually under the passenger seat, but it can also be installed inside a cabinet or storage box with ducting run to vents.
The first step is to figure out where the heater will be installed. It is crucial to know this beforehand so that you can measure all wires, ductwork, and fuel lines to ensure you have enough material. The heater must be mounted on a block of wood, and holes must be drilled for the intake, exhaust, and fuel line. The fuel line hole is very small, and a regular drill bit can be used. The heater must be oriented correctly, with the silver exhaust hose towards the back and the black intake exhaust hose facing the front.
Once the heater is mounted in place, you can start to run the control wires from the thermostat and fuel pump. After the wires are run, the control panel can be mounted, and power can be hooked up to the unit. Once the power wires are connected and the control panel is plugged in, the lights should turn on.
The Espar heater requires a 12v power source capable of providing up to 18 amps (start-up draw). It is recommended that the heater be wired into a battery bank separate from the vehicle starter battery. This is because, when other appliances are run off the starter battery, there is a risk of depleting the starter batteries, leading to a breakdown.
The Espar Airtronic D2 heater uses both electric power and fuel to operate. It is a dry fuel source, meaning it won't cause moisture to build up inside the van. It can run for 24 hours on one gallon of diesel, which is excellent in terms of consumption. Diesel is more energy-dense than propane, meaning it will take less fuel to heat your van.
