Espar Airtronic D2 vs Espar Airtronic D4

The Espar Airtronic D2 and D4 are both models of diesel-fired air heaters, but they differ in terms of their heating capacity, applications, and size. Here’s a comparison of the two models:

Espar Airtronic D2:

Heating Capacity: The Espar Airtronic D2 is a smaller model with a lower heating capacity compared to the D4. It typically provides a heat output of around 2.2 kW (7,500 BTU/h).

Applications: The D2 model is often suitable for smaller vehicles and spaces, such as cars, vans, camper vans, and smaller RVs.

Size: Due to its lower heating capacity, the D2 is generally more compact and takes up less space when installed.

Fuel Consumption:The D2 consumes less diesel fuel compared to the D4 because of its lower heat output.

Heating Time: It might take a bit longer for the D2 to heat up the interior space compared to the D4 due to its lower heat output.

Espar Airtronic D4:

Heating Capacity: The Espar Airtronic D4 has a higher heating capacity than the D2, typically providing a heat output of around 4 kW (13,600 BTU/h).

Applications: The D4 model is suitable for larger vehicles and spaces, such as trucks, buses, larger RVs, boats, and construction equipment.

-Size: The D4 heater is larger compared to the D2 due to its higher heat output and capacity.

-Fuel Consumption: The D4 consumes more diesel fuel due to its higher heat output. However, it can heat up larger spaces more quickly and effectively.

Heating Time: The D4 can heat up larger interiors faster compared to the D2 because of its higher heat output.

Choosing Between D2 and D4:

When deciding between the Espar Airtronic D2 and D4, consider the following factors:

– The size of the vehicle or interior space you need to heat.

– The heating needs and comfort level you require.

– Fuel consumption and available fuel tank capacity.

– Available installation space.

– Budget considerations, as the D4 is generally more expensive due to its higher capacity.

In summary, the main differences between the Espar Airtronic D2 and D4 are their heating capacities, applications, and sizes. The D2 is suitable for smaller spaces, while the D4 is designed for larger spaces and vehicles with higher heating requirements.
