When installed properly, a quality diesel heater will work without any issues for 8-10 years. All you need to do is to start the air heater every two months, allowing the fuel and combustion system to work for 15+ minutes, and that’s it. So, after you finish installing the air heaters, you may realize how the power cord leftover is too long and that you need to coil it up and secure it in place. This is the only right thing you should do if the cable is too long – anything else might result in electromagnetic wave interference. You have probably noticed that the exhaust muffler has a small hole in it. That hole allows the condensation droplets that form when diesel burns to flow out. But, for that to happen, that hole needs to be facing down when you install the muffler. Direction of exhaust muffler Steve the tuning of these heaters is important, not very difficult, but seems like a thing of mystery and complication when you read instructions or are a first timer. YouTube has a lot of well intentioned instructional videos that show the process and it’s a good medium for showing rather than describing which in this task is useful. Since diesel heaters use a fuel pump and can require a high fuel flow rate, it’s recommended to use a screen filter.

But, if you don’t have enough room for the fuel pump to be mounted tilted, mounting it horizontally can work too.To this I first added a cheap visual (but not functional) copy of a Webasto exhaust silencer (bottom left in photo right). This has a straight-through hole from end-to-end surrounded by a spring stretched from end to end. You can enjoy the warm, fresh air in the cold weather in a cabin with the Warmda diesel heaters installed.

At low temperatures, the water will freeze, reducing the diameter of the exhaust pipe, and affecting the combustion performance of the diesel heaters.

That’s why we recommend that all diesel heater manufacturers and sales stores, and customers should use an exhaust pipe with a spiral connection. Only this type of connection will allow the exhaust pipe to hold the diesel heater exhaust system in place securely. 14. Selecting Exhaust Pipe Material And Construction Adding gasoline or additives to prevent fuel gelling offers no real solution but only seem to help on a limited basis. They can have a negative effect on the engine´s performance and life cycle, not to mention, they must already be added before it turns cold. Screen fuel filter I installed in my Vevor portable diesel heater. What Fuel Filter is Best for a Diesel Heater?

It is also a good idea not to mount the heater’s control panel too high. As you know, hot air is lighter than cold air, and if you install the control panel too high, near the roof/ceiling, the air around it will be the first to heat up, and the sensor inside the control panel will turn on the heater prematurely. The construction of this ‘upgrade’ muffler is interesting. The housing is a rectangular aluminium extrusion and the ends (hardly visible) are identical aluminium castings. Inside is an S-shaped air path defined by two S-shaped perforated half-tubes, also cast from aluminium. Unlike the first filter, this one does have glass fibre wadding wrapped around the outside of the perforated tube.The fuel line is held together with some simple clamps that can be loosened using a flathead screwdriver. I’ve been running my portable diesel heater for a few days now and so far I’ve had zero issues with the fuel filter. Warmda LLC also has a silent fuel pump option. It is installed in exactly the same way as a regular oil pump. 10. Proper Distance Between The Fuel Pump And The Main Engine One common mistake when installing the tube of the diesel heater’s cooling air intake systems is that people set it up so that it draws the air from the outside and blows it into the compartment’s interior. Some portable all-in-one diesel heaters will have a fuel filter already installed, but many Chinese diesel heaters don’t come with one.

The ideal location for the control panel is halfway up the height of the cabin. If you install it at this height, the heater will operate perfectly. And the fuel efficiency is the highest. To secure the exhaust pipe to the diesel heaters exhaust port securely, you need to have a spiral exhaust pipe connection. The diesel heater directly connected to the combustion exhaust pipe. The outlet is made of aluminum, while the exhaust pipe is made of stainless steel. It relies on an exhaust pipe clip to secure it to the exhaust port. Spiral interface of Warmda exhaust pipeMany manufacturers recommend you to install a fuel outlet at the bottom of the tank. That will connect it to the fuel delivery line directly—a simple installation method and very easy to use.
