How Does A Diesel Air Heater Work?

A diesel air heater is a device that helps maintain a steady temperature in the cabin of a car or boat.

It sucks in air from the surroundings, mixes it with fuel, and then ignites it to raise the temperature inside.

This allows the unit to be easily connected to the existing fuel system, making installation even simpler.

Are diesel air heaters safe?

I was on Facebook not long ago when I came across someone who said that a diesel heater was the best investment they had made for their van. They appeared to be a cost-effective way to heat a mobile house.

Modern diesel heaters are extremely safe, particularly when used inside. They emit less carbon monoxide and are usually more fuel efficient than gasoline engines. In order to prevent overheating and fires, these heaters are frequently equipped with shutdown mechanisms.

Here are some of the safest diesel heaters I recommend if you’re thinking about buying or using one. And here’s what you’ll need to know ahead of time:

Do diesel heaters need to be vented?

It’s always an experience to live in a caravan. What could be more enjoyable than hopping from one location to the next, taking in the sights and enjoying the company of those around you?

Even if your destination is warm and tropical, you will almost certainly experience some cold nights, necessitating diesel installation for those who live in trailers.

People who plan to stay in a caravan have a lot of questions, and one of them is whether or not diesel heaters need to be vented. In summary:

Ventilation is required for diesel heaters. When diesel is burned, it produces a number of gases. These gases are hazardous to your health as well as the health of people within the caravan or vehicle. As a result, there must be a method for the gases to be evacuated from the diesel heater.

I’ve listed some of the safest diesel heaters I can think of. Continue reading to learn more about how diesel heaters work and why venting them is so crucial.

How does diesel space heater work?

Air is drawn into the combustion chamber by a diesel space heater from an external intake line. The air is then mixed with atomized diesel for an internal combustion process that ignites the diesel while also heating the heat exchanger’s surface.

In the industrial, commercial, and construction industries, diesel space heaters are an efficient source of heat.

Do diesel heaters produce carbon monoxide?

Diesel heaters are generally considered to be safe devices. While they do emit carbon monoxide, it is at a lower quantity, so as long as there is adequate ventilation, it should not affect users. They also have a sealed combustion chamber and exhaust that is vented to the outside. As a result, you don’t have to be concerned about inhaling toxic fumes because the exhaust pipes discharge waste from the combustion process outdoors, leaving the air in your cabin clean and safe to breathe.

Do diesel heaters stink?

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.

Do diesel heaters cause 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.

Can a diesel heater heat a house?

Yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes Diesel is near enough to home heating oil to be used as a replacement, and it burns safely. In fact, our experts advises keeping a moderate amount of diesel on hand in case of an emergency, as you never know what can happen, such as terrible weather or an unforeseen supply shortfall.

However, keep in mind that if you decide to keep diesel at home, it must be stored in the proper container (yellow denotes diesel, red denotes motor gasoline, and blue denotes kerosene, just so you know!). You should never keep diesel fuel for more than six months at a time since the quality diminishes and it becomes dangerous. Even if you use fuel additives to extend the life of the fuel, storing it for a year is the maximum amount of time that is prudent.

However, this should only be a short-term remedy! While diesel is totally safe and functional as a temporary heating oil substitute, it isn’t meant to be stored in your tank for long periods of time. Diesel fuel is an excellent alternative in a pinch, but it is ineffective and not recommended for long-term heating.

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!

Can a diesel heater run on red diesel?

Any diesel-powered engine or machinery can use red diesel. It’s also frequently substituted for heating oil, however we don’t recommend using it in boilers or furnaces. Our furnace fuel for household consumers, kerosene, is a better solution for heating reasons for industry.

It’s permissible to utilize it in vehicles and machinery that don’t travel on public roadways. It is significantly rebated to help businesses like as construction, agriculture, and others deal with the financial burden of fuel costs.
