How Diesel Heater Works?

The diesel heater is based on a simple concept. You can tell if it will work for you if you understand how it works. Let us take you through the process.

First, cold air from outside the car is drawn in through an exterior pipe. After there, it makes its way to the combustion chamber. It uses a high-pressure ignition method to combine with diesel to generate heat. According to the temperature setting you’ve chosen, this will offer adequate heat.

Warm air is contained in a huge heat exchanger, which is then exchanged with cool air. The exhaust pipe exhausts any potentially dangerous combustion exhaust gas outside of the car, ensuring that you do not inhale it.

How does a diesel heater work?

As previously stated, the differences between a diesel air heater and a diesel water heater are minor.

Nonetheless, it’s critical to understand what distinguishes them and what they have in common.

This, I feel, will assist you in deciding which type of heater to choose from these two possibilities.

How does Diesel Air Heater vs. Diesel Water Heater Work?

A diesel air heater works by bringing in fresh air from outside and mixing it with fuel (diesel).

After that, the mixture is ignited to generate heat, which is subsequently dissipated from the heater into the surrounding environment.

In contrast, a diesel water heater heats water from the vehicle’s reservoir to provide hot water or steam.

The steam then passes via a heat exchanger, dissipating heat that is subsequently dispersed to the outside environment.

The hot water also travels to the engine, warming it up to prevent cold starts.

Diesel Air Heater vs. Diesel Water Heater Similarities

  • You have a variety of control choices for both. This implies that whether you buy an air or water heater, you’ll be able to operate it with a smartphone, a remote, or a timer.
  • Their structures are frequently identical, with the exception that the latter substitutes air with water.

Diesel Air Heater vs. Diesel Water Heater Differences

To be honest, the distinction between a diesel air heater and a diesel water heater is minor.

Fuel is mixed with air from the vehicle’s interior to generate heat in the diesel air heater.

The hot air is then forced into the heat exchanger, where it is dispersed into the surrounding environment by the blower fan.

When air and water mix in a diesel water heater, heat is generated when the combination is ignited by the ignition plug.

The blower fan extracts the heat from the hot water and blows it into the surrounding surroundings.

This water will also go to the vehicle/engine, vessel’s heating it and eliminating the possibility of a cold start.

The water heater heats both the interior and the engine of the car, whereas the diesel air heater simply heats the vehicle’s interior atmosphere.

Another distinction between these two types of diesel heaters is the installation process.

The diesel air heater can be installed in the vehicle/marine vessel’s cabin or chassis.

This is because all it need for combustion is air from the outside environment.

On the other hand, a diesel water heater must be installed in the engine compartment of your vehicle/vessel.

Because the heater will need to use the vehicle’s water circuit system to generate heat, this is the case.

You can use the water heater to raise the temperature in your vehicle and warm up your engine in the winter.

Essentially, this is all there is to know about diesel air heaters and diesel water heaters.

Consider the advantages and disadvantages of these two types of heaters and select the one that best meets your needs.

How does a 12v diesel heater work?

A diesel heater uses an intake duct to direct the caravan’s cold air. After that, it travels over a hot cylindrical metal surface. Any air that passes through it is heated. After that, the ducting delivers fan-assisted air to an outlet.

Can you run a diesel heater indoors?

Yes, diesel heaters can be used inside. They are extremely quiet, so they won’t bother you while you’re working or resting. They also have outstanding safety measures that make them suitable for indoor use.

Diesel heaters, for example, have an automatic shutdown feature that prevents the temperature from rising above a specific level while in use. This means that the heater will not cause a fire if it becomes too hot.

Because the combustion chamber is totally sealed and the exhaust is discharged outside, there is no risk of carbon monoxide poisoning. If you’re considering of using a diesel heater indoors but aren’t sure if it’s safe, don’t be concerned; they’re completely safe.

How much fuel does a diesel heater use per hour?

What is the fuel consumption of a diesel heater? The total fuel consumption every hour is totally dependent on a lot of factors such as the heater model, ambient temperature, and even altitude, but you’ll normally be looking at 100ml per Kw.

Does a diesel heater need electricity?

Diesel heaters are powered by the vehicle’s main diesel tank as well as a recreational battery or an electric source. They’re common in larger cars since they can have both hot air and hot water systems. If you’re camping all year and want to take a hot shower, this is a great option!

A typical diesel heater uses 0.1 litres of diesel per hour as a rough estimate. It’s worth noting that the heater only consumes fuel when combustion is taking place.

The thermostatic controls and the fan both require 12 volts of power.

The consumption varies depending on the heating power required and the type of heater; as a general rule, it ranges from 10 to 50 watts.

The lowest wattage your electrical input must be in order for the heating to work is specified in the user handbook.

Most diesel (and gas) heaters warm the air with a heat exchanger before blowing it around the vehicle with a 12v fan. Without entering the car, the air required for combustion and exhaust is routed directly from the outside into the sealed combustion chamber and then back out. It is critical, as usual, to ensure that all safety criteria are met when installing. (See this blog’s safety section!)

Cons of diesel heating in campervans

  • They (usually) consume more electricity than a gas heater. If you have solar panels, this can be offset.
  • Webasto heaters range in price from £800 to £2000, depending on the KW output.
  • Alternative models, such as this one, are becoming more popular, but if you’re fitting yourself, be wary of the dangers of buying from abroad.
  • You could find that you need to translate a lot of Chinese instructions…

Simon, Finn’s owner, has solved many of these concerns in his Mercedes Vito campervan conversion by installing a completely new style of diesel stove. It’s called a Refleks 66MK, and it resembles a wood stove but functions more like an AGA, with a convenient stealth mode!

Do diesel heaters smell?

It’s usual to smell diesel when the engine first starts up because the engine isn’t yet hot and the first spray of diesel hasn’t completely burned. Inside the van, there should be no odor at all. Tell us a little more about the heater, such as the brand, model, and so on.

Can you run kerosene in a diesel heater?

Before using diesel in a kerosene heater, there is no need to add anything to it. However, many people claim that using chemicals improves their performance.

  • Isopropyl alcohol: For each 5 gallon can of diesel, add 40ml (a little more than 1/8 cup) of 91 percent isopropyl alcohol. I’ve also seen far greater alcohol-to-diesel ratios advocated, such as 80ml per gallon.
  • Kerosene: Kerosene and diesel can be mixed in any ratio and burned in your heater. The most common recommendation is to use a 1:4 ratio (1 part kerosene to 4 parts diesel).

Keep in mind that you should always have a backup plan in case of an emergency. Other emergency home heating methods can be found here.

Do you have a kerosene heater that runs on diesel? What advice do you have to offer? Please share your thoughts in the comments box below.

Is it better to use kerosene or diesel in heater?

Because kerosene has a lower viscosity than diesel, it burns hotter. This can assist heat the house, but it can also cause issues if the heater isn’t designed to manage heat that’s hotter than regular heating oil heat. The heat from a kerosene heater may readily heat a standard home in a warm environment if your furnace is suitable for kerosene, according to “The Decatur Daily News.” When diesel is unavailable, kerosene heating oil K-1 is typically utilized; nevertheless, it is more expensive than its diesel cousin. Installing a fuel oil heater also makes it comparable to standard No. 1 heating oil, which is useful if you choose to swap oils later.

Are Chinese diesel heaters safe?

Chris feels that many of these low-cost heaters are made of low-quality materials. The heat exchanger’s thickness, for example, which is prone to burning through to the heated air outlet, allowing exhaust gases to escape. Not only is this a fire hazard, but it also implies that carbon monoxide could infiltrate the caravan’s living space.

Carbon monoxide poisoning is a serious threat, especially in caravans and motorhomes. Due to the enclosed nature of the room, proper ventilation is necessary to prevent the build-up of toxic vapors. Items placed in the RV, unfortunately, can partially or totally obstruct these vents. If a heater is left on overnight and carbon monoxide builds up, the inhabitants will be utterly ignorant of the danger, putting their brains at risk of death or brain damage. This is compounded by the fact that carbon monoxide detectors are still not required in recreational vehicles (even if the unwary still insist on using the gas stove to heat the van).

The brand-name heaters make a big deal about how safe they are. Webasto, for example, promotes safety measures such as:

  • The pump will switch off in the event of an error or fault code, preventing the burner chamber from flooding with fuel.

Before making a purchase, Chris advises checking the specifications of any diesel heater to make sure it includes these safety features.
