How Does a Diesel Heater for Van Work?

Before understanding the general instructions for diesel heaters, it is very important to look at how they work.

As you understand from their names that they are working with diesel fuel. So, there is a diesel tank that we need to attach to a proper space. The system does not take diesel fuel from the van’s tank. There is a spare tank that you need to put diesel fuel inside it. So, the place o the tank must be easy to reach the place. When it runs out of diesel fuel, you must be able to replace the fuel easily without any difficulty.

So, there is a connection between the diesel heater and the fuel tank. The length of the connection is very important. Because there is a fuel pump that pumps the diesel fuel to the diesel heater system. And the length of this connection must not be very long. Because the capacity of the pump must not be exceeded which will prevent the fuel supply to the diesel heater for van. In most of the models, the length can be between 1-2 meters.

Also, there must be a clean air connection to the diesel heater. Because we need to mic the fresh air with diesel fuel to get combustion. And the system will take the fresh air from the outside. This means you need to open a hole to place the hose and intake system of the device that will provide fresh air from the outside.

And also there will be an exhaust hose. You need to place the exhaust hose that will look to the open atmosphere. You need to expel the burnt gases outside. And you need to make sure that the exhaust gases will not mix with the fresh air that we are taking to the system.

As you see that the placement of the system is very important. If you are building a van from scratch, it is very hard to select a proper space for it. We recommend that you find yourself a mechanic to do it.
