Cabin air heater (dry heater)

It is impossible to imagine operating a modern car without using the latest climate control equipment. One of the most popular samples of such equipment is an autonomous heater, also known as an air dryer. The device allows you to quickly create a comfortable environment in the cabin or cabin of the car, and stably maintain it for a long time. The most popular among Belarusian consumers are dry heaters Webasto and Eberspacher, produced by the German company. A leader in the field of automotive air-conditioning. They are installed as standard on numerous models of trucks and cars, buses and vans. Also dry interior Webasto is very popular as additional equipment. over, these devices can be used for heating cargo compartments, garages and domestic premises, cabins and holds of river and sea vessels, etc.

Thus, cabin air heaters can be used with high efficiency, which makes them simply indispensable in many situations!

What they are, heaters?

Actually, there are two groups to which such devices belong:


The autonomous heater of such type is intended only for heating of a car salon. The principle of operation of such devices strongly resembles the work of a hair dryer, when the incoming air is heated. The figure below will help you to understand the structure of this autonomous heater.

In such a device the fuel (either regular tank of the car is used, or additional tank is installed) burns in a special combustion chamber. The heat generated heats the incoming air, and then it is sent to the cabin heating. As a rule, such a heater is installed inside and it is necessary to lay the fuel pipe to the tank and the exhaust system.

What to choose an autonomous heater for your car

Webasto is the name of the most famous German company, the manufacturer of autonomous engine preheaters and autonomous air heaters of passenger compartments and cabs. This firm produces a number of other automotive products, but it is known, first of all, already mentioned equipment.

Let’s divide the areas of application into:

About the first ones you can look in the corresponding section of our site.

Let’s talk about the second point.

The air heater, it is the same among the truckers “dry heater”, an indispensable thing in the cold season (in our climate not less than 8 months a year).

Working principle: the heater consists of 2 circuits. In the first circuit in the combustion chamber burns fuel (usually diesel), there is supplied cold air from the street to support the combustion process. The flame heats the heat exchanger, on the outside of which air taken from the cabin is passed through. In the process of its movement along the second circuit, it is heated to specified parameters. It heats the interior.

Exhaust gases are exhausted from the 1st circuit to the outside of the cab dimensions. No penetration of combustion products into the passenger compartment.

The process of air and fuel is regulated by the automation of the electronic control unit. It is started either with a rotary switch or a timer with a display.

Fuel. usually diesel with kerosene, but there are also petrol variants (so far only the Germans)

Power of the air heater:

2) 3 or 4 kW for absolute majority of the cabs (“long distance trucks”, dumpers, etc.).д)

3) 5 and 8 kW are usually used for the caravans and motorhomes

Producers of air heaters:

  • Webasto. Germany. The most famous brand.
  • Eberspacher. Germany. The second brand, not inferior to the first.
  • Planar.Russia. Great heater. Cheap. Reliable. Proven by. Equal to the Germans.
  • Pramotronik. Russia. Distant descendant of Webasto. They say the reliability has gone up. Did not check.
  • SHAZ. Russia. Former Russian defense industry. Ruined brand. dead than alive.
  • BELIEF. China. expensive than Planar, cheaper than Germans. Without normal service support.
  • BRIZ. Czech Republic. Rare guest in Russia.

Our clients get an opportunity to provide a driver with a full-fledged rest and very quickly recoup the funds invested in the purchase of equipment by dramatically reducing fuel consumption during stops (rest, loading-unloading, customs, downtime, repairs, etc.).п.). If cabin heaters are installed on construction special equipment, the economic effect is achieved by increasing the productivity of the operator, providing better visibility and increasing the safety of construction operations.For payback calculation of air heater we offer the best price-quality ratio. below.For the specified time, we have sold tens of thousands and installed thousands of autonomous cabin heaters of various firms on the most various cars.

We believe heaters PLANAR from ADVERS plant in Samara today have the best price-quality ratio. The products have long gained the respect of the truckers and, without a doubt, are on a par with the most famous German brands Webasto and Eberspacher.

PLANAR has all necessary European quality certificates, successfully sold in Europe and America.

We sell and install all 3 first brands, but the ratio of sales is 200/1 in favor of Russian products (according to our long-term statistics).

As for the German devices. First of all it’s brand. Now you pay 50% of the heater price ( like a Mercedes or Bentley). They are good, but expensive. You choose what suits you best. We can only advise based on our experience.

Buying and installing from us our customers can be sure that:

  • Installation will be carried out by specialists with extensive practical experience in this field
  • The equipment is provided with a real warranty in any point of Russia
  • Warranty periods are as stated
  • Equipment is bought either directly from Samara factory ADVERS, or from distributor Webasto or Eberspacher without additional intermediaries. We do not have “gray” heaters that can cause warranty problems.
  • We repair often and a lot of all heaters, so the masters have great experience in repair. There are enough pseudo-masters on the market, who can “put” heater in the car, but there are only a few good repairmen. We have them.
  • We have one of the largest warehouses in Russia for Samara heaters. Almost all spare parts are available. We deliver all necessary things to our warehouse by our own transport directly from the factory.

Calculation of the payback on the cabin heater for the “long-haul”:

Let’s take an average output of 3kW at Samara PLANAR-4DM2-12/24v and 2kW at Germans (by price Webasto and Eberspacher are identical on heaters of one output) Average time of night parking. 10 hours.30 /litre ( autumn 2019)Average fuel consumption of these heaters is 200g/hour., т.е. 2 liters/night, which is equal to 88 /nightThe idle consumption of a long-haul truck is about 5 liters/hour, t.е. 50 liters/night, which equals 2217 /nightTotal savings of 48 liters/night, which equals 4844.30=2126 /nightThe cost of heaters (the from the sites of distributors for 5.09.19)

We divide the cost heater cabin on the cost of fuel saved and get payback period air heater: PLANAR-4DM2-12/24v 21900/1632 = 14.06 (13 nights) German heater 45600/1632 = 21.44 ( 22 nights)The difference in price and payback time is almost 3 (. ) times with the same performance indicators.In this calculation, the simplest variant was taken. We have not counted rest, loading-unloading, customs, downtime, repairs, etc.п. That makes up a very large chunk of the driver’s time during the trip.

CONCLUSION: the operation of vehicles without self-contained cabin air heater deprives the owner of a significant portion of profits due to the overspending of spent fuel, which could be saved without damage to the case. Saved means BORROWN !

For heating minivans and large American vans we can recommend 4kW and 5kW equipment, and 8kW equipment for truck boxes.

Dry hair dryer in the car: lessons learned after a year of use

I already wrote about the hair dryer last year, but a year later I decided to write a more detailed post for those who doubted the necessity of the installation before the new season of cold weather.

The issue of heating in my car arose for several reasons at once:

The choice of systems for heating, by and large, comes down to two technically different options: a dry hair dryer only for the cabin (the most popular. domestic Planar and German Ebershpacher) or “wet” heating (most often put a version of Webasto, although there are many others). For myself, I chose a dry hair dryer, in favor of which played a complete independence of the technical systems of the car (Webasto heats the coolant and it goes warm air into the cabin at the expense of the regular heater). The second important factor was lower consumption of fuel and energy for air heating. The ability to heat the engine for me is not so important, as severe winters in our region does not happen, the problems with starting even at.30 my car has never had any problems starting and in home mode most starts either in a warm garage or before it has cooled down completely (for example, after a trip to the mall).

Of the dry dry dryers, I chose Planar, but completely by chance I managed to buy a brand new Ebershpacher for similar money on a well-known free ads site.

The hair dryer was integrated under the car’s rear fender trim, the fuel intake is from the regular tank, and the combustion air is from the street, from underneath the car. The muffler and the exhaust are in the same place. We didn’t have to make any new holes in the body, we used the ones we already had. The power to the hair dryer is independent of the ignition key position. This on the one hand allows to fully unplug the circuits and use the hair dryer without plugging in other consumers and without leaving the key in the car, on the other hand it adds a risk that I would forget to turn it off in the parking lot. But I found the risk acceptable.

The first winter showed: even 20-30% of 2 kW power is enough to keep the car warm in any frost. 50% power is already very hot. Fuel consumption of 100-200 liters per hour (in comparison with 3-4 liters at starting up the engine of an SUV in frosty weather) and electricity consumption, which in no way affects car starting even after 10 hours of hairdryer working is quite a modest payment for comfort and saved motoresource in any weather.

The entire installation project cost 25,000 for the hair dryer, and 10,000 for the installation, which is also not expensive.

As for the sound. you can only hear the rustling of air entering the cabin and you can hear the quiet noise of the exhaust outside the car. The sound does not disturb your sleep in any way, that is the main thing.

Popular producers of heaters for a car

Autonomous heaters (heaters) for cars are produced by many companies. But not all brands can boast of reliability. The best brands are listed below:

  • Webasto. The German company is widely known for the quality of its products. It has been on the market for over a century and traditionally surprises consumers with innovative technology.
  • Eberspacher. A small family brand from Germany for more than 150 years of existence, has managed to grow into a serious brand with offices in different countries.
  • Belief. A well-known company that produces different types of equipment. It is characterized by reliability and innovative approach to product line development.
  • Planar. The Russian brand, whose plants are located in Samara, produces affordable and high-quality products adapted to Russian realities.

What is a dry and wet hair dryer?

Autonomous heating systems. Are used to maintain a given temperature in a closed room.

They are used in mobile cabins or trailers, in cabins of various machinery, where own heater is not enough (or it is simply not provided by construction). They are widely used for heating truck cabins during night parkings or to maintain a comfortable temperature while driving (for example, the heating system of the Mexican-made Peterbilt truck is simply not designed for sub-zero temperatures below zero).10). The independent heaters can be air and liquid.

The air heater (dry hair dryer) works due to heating of sucked air by electric heating elements powered from the car battery. Such a heater is usually installed outside the heated room, the air ducts are winded inside. The air intake can be carried out both from outside and from inside the room.

The air independent heater is simple and convenient in operation (modern dry heaters are equipped with electronic block of temperature regulation and support the thermal mode like a climate system). The disadvantages of such heater are its considerable power consumption and, as a consequence, the accelerated discharge of storage batteries.

Liquid heater (wet heater). Such an independent heater is built into the cooling system of a car engine. Principle of its operation is as follows. Heating element (or boiler) through the combustion of fuel heats the antifreeze in the small cooling circle up to 70.80 degrees, thereby heating the engine cylinder block and feeding hot antifreeze into the car’s own cabin heating system. Circulation of the antifreeze occurs naturally (some models have a small pump built-in), and the motor of the car’s climate system is powered by the battery. The benefits of a wet hair dryer. confident maintenance of comfortable temperature of the engine and automobile saloon, small power consumption and insignificant (up to 0,7 l. per hour ) fuel consumption. Minus. very complex device, requiring installation and service only by specialists.

What is a dry and wet hair dryer

Nissan Safari I have a diesel. In general, all the cars that I had. it’s diesel and manual. If you like, it’s such a religion: I think an SUV should roar, be tractive and omnivorous. Well, and I enjoy driving a car with a manual.When in the year 2011, I decided to put a heater, I reasoned as follows. The fuel may freeze or thicken in extreme cold, and then I would not only be unable to drive, but also heat in the car. But if I put a gasoline heater, I can sit in a warm car and wait for help. It would seem logical. And now when I start saying that, I get approving nods, agreeing with the seemingly common sense reasoning. That’s not even remotely true! For two reasons. First of all, if you’re going on a trip in severe cold, be kind enough to prepare your car. There is no problem nowadays to equip a car so that the fuel in it does not freeze even at.50 degrees. Rather, the iron will start to burst from the frost, and the diesel can be kept from freezing.For this purpose there are now produced: flow-through fuel heaters, fuel filter nozzles, band heaters, put on the fuel pipe, nozzles on the regular fuel. intake. You can also direct the flow of hot air from the cabin heater exhaust pipe to heat the sump and fuel tank. The air comes out very hot. But! I warn you right away, it is necessary to do it competently, otherwise sooner or later your car will simply burn down!

If you did it right, then not only are you guaranteed to have a working cabin heater in freezing weather, but more importantly, and the engine will always run.Secondly. Installing the heater, working on a different fuel than the one that consumes your car, requires a very competent installation and more complicated. And where there’s extra complexity, there’s a greater chance that something won’t work. Well, to find a good craftsman. big problem. often than not, it’s the wrong hands. And even if you find a clever craftsman, who has repeatedly put heaters, not the fact that in a year or two they will work.That’s how I did it. After suffering for several years and wasting a lot of money and effort, I came to the conclusion that it is better on a diesel car to put a diesel Webasta and do not wiggle. The heater Webasta. German and made of very high quality. It requires electricity and fuel. Give it to her and you’ll never have a problem. And, of course, the fuel must be normal.

Nissan Safari decided to put a fuel tank in the rear power bumper. Which is actually not a smart idea, because on impact, there could be a spark and there would be a fire.The first tank was welded from ordinary metal and immediately began to rust inside. Anyone who’s seen a Webasto knows how thin its piping is. Hole for fuel with a needle. So any crumbs or dross immediately clogs it. After agonizing for a while, decided to order a stainless steel fuel tank. I paid 3000 for the first tank and 7000 more for the new one.But these modifications didn’t make it better, the heater still wouldn’t start every once in a while or wouldn’t start at all. Went to the installer a couple of times, and he thought of the piping for 100. Didn’t last long.In 2012, after traveling all over Mongolia, we stopped in Mongolian Altai. Since it was pretty cold out there, I decided to turn on the heater. It wouldn’t start, of course.Already at home I tried to deal with the heater. The reason it wouldn’t work was because the pipes were too clogged. The heater would give me an error and then turn off.In all the years of use only on one trip to Baikal in January, the heater worked properly.Last year in the north of Buryatia on the lake Baunt I had to heat four nights on the stove with the engine running. This is not very comfortable: in addition to high fuel consumption, the car shakes quite a lot and there is a chance of getting burnt by the car’s exhaust.The last straw of patience was a trip to the Baikal-Amur Mainline in March 2015. At night the temperature dropped to.35. I had to save fuel, otherwise it might not be enough. So until I got the heater going, I didn’t go to sleep. Thus, every night began a tambourine dance, which lasted from half an hour to an hour. This is instead of going to bed and resting after quite a hard day. I’ve done everything: I’ve reset the heater by disconnecting the electrical plugs, I’ve blown into the fuel tank when the temperature.20 degrees, and repeatedly turning the heater on and off. As a result, I never slept with the engine running.The reasons for which the heater would not work, I think there are several: the wrong, not fen-style height of the fuel tank and pump, debris in the tank, improper pipe routing.In principle, every night I could unscrew the pipe clamp, blow through it and after that, most likely, the heater would start. That’s what I did once in the garage. For this purpose I had with me on the trip a pair of medical tweezers which was very handy for taking off the hose and clamping it, and a special copper tube without which it is impossible to reach the hose with one’s lips for blowing. But in severe frost, at night, climbing in the snow under the car, as it is not very much wanted. It was a shame. After spending more than 60,000 on the heater, I could not use it properly.The homemade tank has a blind plug, resulting in a vacuum. In the regular fuel tanks in the lid has a valve, through which the air is etched. The hole for the cap in the tank is made without a rim or neck, so the tank gets debris. There are a lot of such subtleties, and they all interfere with the normal work of the cabin heater.So when I bought the Land Cruiser 100, I had no doubts that I would put a diesel cabin heater. Since in July I may need a Webasta, I decided to install it now.In principle, almost everything is satisfactory. Although there were some doubts. About them now and tell you.This is how it turned out as a result.

It is difficult for me to change after the Safar in a quiet, calm way. All the time out of habit, something you want to change or improve. At least a little bit. But then I stopped, remembering the words of my good friend Alexander Kanin (link to video), who has repeatedly said: Andrew, do not get into the car, do not try to change something. Thousands of engineers and technicians were thinking when they were creating the car and we were so clever, trying to screw around and then it breaks. Alexander has the right to say that, he was going through the tuning of cars and got sick over it. Our trip to Mongolia illustrated just how right he is. Back then, everything was breaking for me and nothing for him.So when installing the heater in the Land Cruiser, I may not have thought this through all that well.I put the heater, like in Safari, in the trunk of the car. Although you could put it under the front seat, or try to put it under the trim. But under the interior trim has already begun work on the installation of the inverter. And under the front seat. At first it didn’t seem like it would fit in there. Actually it is not so: Webasta goes in there, you only need to trim the mat, and there is quite a deep recess.Before I put it in.

The location of heater in a cabin or under a front seat has some basic differences. Under a seat the heater doesn’t obstruct you and it is reliably hidden from mechanical damage. In the trunk, it’s in the middle. And if you fold the seats, it will be the only uneven spot in the trunk of the car. This can sometimes cause problems. I didn’t think of that when I was installing it. If I had it in the Safar, I put it in the 100.

Equally important is the difference in the way the heater is connected to the fuel line. If the heater is installed in the trunk or hidden under the trim behind the car, it is usually connected through a tee near the fuel tank. It’s feng shui, as the manufacturer strongly recommends. The upside: do everything the right way as much as possible, the downside. There is no fuel purification, and our fuel is far from ideal. Especially on long trips and in other countries. I’m talking primarily about Asia.Button is mounted high enough in the tailgate area to make it easy to turn on the heater after installing the sleeper.

Installation under the seat allows you to connect the heater to the fuel system after the fuel filter. So the fuel will be clean. That’s a plus. But in this case, the Webasta pump is under extra strain because it is not designed to pull/suck fuel through the fuel filter and the car’s piping. And this is already a minus. In the forums, however, write that this method of connection is quite normal and time-tested.Extended exhaust line connected through the muffler. Made in order not to get burnt while sleeping.

If I manage to install a small diesel filter in front of the heater pump, then the problem will be solved. I will change it every six months and that’s it. The only thing is not very convenient location of the heater in the middle of the trunk. But it is possible that the sleeping bag, which I will put in the trunk will not dismantle after every trip, then it will not be a problem.I have deliberately painted in detail, in the hope that the information will be helpful to someone. Well, it’s up to you to draw conclusions).
