How Does A Diesel Night Heater Work?

A diesel night heater is a rather simple mechanism. The following is a very simplistic explanation of how a diesel night heater works.

  • An intake pipe draws the air required for combustion into the diesel heater. This pipe connects the vehicle’s interior to the exterior via the floor.
  • The air is now forced into the combustion chamber, where it is combined with diesel fuel under pressure.
  • The temperature of the outer combustion chamber rises as a result of the heat generated by combustion. The associated heat exchanger is then heated.
  • After combustion, all exhaust gases are securely evacuated to the outside of the vehicle via an exhaust system.
  • The temperature of the air rises as it travels around the heat exchanger.

Can you run diesel heater all night?

If you’re considering purchasing a diesel heater, you’re undoubtedly asking yourself this question right now. Diesel heaters have been around for a long time and are widely utilized around the world due to their efficiency and dependability. They’re also thought to be extremely safe.

Diesel heaters come with numerous safety features that ensure that they are fully safe to use. For example, to avoid the risk of overheating, which can result in a fire, diesel heaters have an automatic shutdown feature that turns off the machine if the temperature rises above a specific level.

Furthermore, diesel heaters emit significantly less carbon monoxide than gasoline engines. Thermostatically controlled diesel heaters are also safe to use while sleeping at night.

Users are also not exposed to a naked flame when using diesel heaters. They start the combustion process using an electrical charge glow pin, which is regarded highly safe. Because of improved fuel quality and burner technology, the exhaust odor of most diesel heaters is nearly imperceptible.

This means you won’t inhale any hazardous fumes because the combustion chamber is entirely sealed and the exhaust is discharged to the outside. While sleeping, there is no risk of carbon monoxide poisoning.

How does a campervan diesel heater work?

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!

How does a night heater work in a truck?

On a cold or frosty day, imagine boarding a heated vehicle and driving away with clear visibility!

Or being greeted by a blast of energizing, fresh air circulating around the inside thanks to the ventilation system!

These are just a few of the benefits of installing a night heater in your car, truck, or van.

Safety through clear visibility

When you have a night heater, your visibility is perfectly clear from the start — without the need to brush ice away.

The parking heater also prevents harmful moisture condensation and re-icing from within the vehicle.

Warmth from the onset

From the start of your drive, the interior of your vehicle is at a comfortable temperature.

Ice scraping and large jackets, both of which can impair your driving, will be obsolete.

No ice scraping

The morning scraping of ice off your windscreen is no longer a concern thanks to the night heater.

The heating system guarantees that your day begins in a relaxing and comfortable manner, making you long to return to your warm vehicle.

User-friendly operation

You can use the digital control switch, remote controller, or GSM remote controller (app on your smartphone) to control it.

It is possible to control and operate the equipment using a different method – with technology, anything is possible!

Intelligent ventilation in summer

A night heater not only keeps you warm in the winter, but it also keeps you cool in the summer.

It cools your parked truck, van, or automobile by pumping outside air into it, preventing the accumulation of severe heat and extremely high internal temperatures.

How much fuel does a diesel night heater use?

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.

Will a diesel heater flatten my battery?

Unless the battery is relatively young, a simple one-amp pull can kill a starting battery overnight. Running the heater off the starting battery reduces the battery’s longevity. In an emergency, you might be able to get away with it for a few days, maybe even a few weeks, but you’re murdering the battery.

Is a diesel heater worth it?

Diesel heaters are commonly utilized and are thought to be extremely safe. They, like LPG heaters, include an auto-shutdown feature if the system temperature rises above a safe working threshold. A leaky LPG fuel line can cause more than just an explosion. It can also harm the nerve system and cause breathing problems.

Can you drive with diesel heater on?

Only a cowl top, which must be mounted freely in the air flow, can be used to operate the heater while driving with Truma S and Trumatic S heaters. T-3 or T-2 cowl tops are recommended by Truma. Otherwise, the flame may blow back, causing the heater to be damaged.

To ensure that the heater functions effectively, the cowl top must protrude at least 10 cm over roof attachments such as roof boxes, ski or luggage racks.

The UN ECE R 122 directive for mobile homes and caravans stipulates a safety shut-off device for heating while driving. This is met by the Truma MonoControl CS gas pressure regulation system. According to Directive UN ECE R 122, a type-tested LPG heater may be operated while driving in Europe if the system comprises this regulator and a suitably constructed gas installation. National laws must be adhered to.

Will a diesel heater stop condensation?

Moisture in the air causes condensation. It then clings onto a cooler surface than the air itself. This is why you’ll find it mostly on windows, but also on the inner roof and anywhere else that hasn’t been adequately insulated.

Where does this moisture come from?

Most of the time, it’s your breath! When you spend time in your van, the air you breathe out is likely to be warmer than the air you breathe in at home. Living in a van with two people and a dog? That multiplies it by a factor of ten!

It can also be caused by cooking without adequate ventilation. When you boil water, steam vegetables, or fry anything delectable, all of that moisture is released into the air.

Another source of condensation is the heating source you have. Some are superior to others. Propane, for example, is known for producing more moisture than other fuels. A diesel heater is known as dry heat since it produces 2x less moisture than a propane heater.

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.
