How to use a catalytic hand warmer. Catalytic heating pad: instructions for using the device. What is the heating temperature of the heating pad

A catalytic heating pad works on the principle of gasoline vapor oxidation on a catalyst, where a chemical reaction takes place with the release of heat, which is transferred to the metal body of the heating pad.

Read this manual carefully before using!

Use only special refined gasoline for lighters as fuel. The use of other types of fuel most often leads to the failure of the heater;
Do not fill the heater with fuel along the edge. There should be at least 1 cm between the catalyst and the upper limit of the fuel level;
If the heating pad cools down completely, gasoline evaporation stops and the heating pad dies out. Use the supplied cover to prevent the heating pad from completely cooling down, or always keep it in minimal heat;
In room conditions, the heating pad heats up to 60-70 ° C. Be prepared for the fact that in the cold, the temperature of the working heating pad will be much lower;
In cold weather, to start the heater, it is recommended to heat the heater body itself, in addition to the catalyst, this will facilitate starting;
In an upright position, the heater heats up most of all, due to the more intense evaporation of fuel, the consumption of which, accordingly, increases;
It is recommended to run the heating pad in advance, while still in a comfortable environment, without wind and in a warm place. It will be extremely difficult to do this in the cold, with frozen fingers, in the wind;
Do not allow children to use the heating pad;
To avoid poisoning, do not inhale fuel vapors and oxidation products.

The operating procedure of a catalytic gasoline heater

Remove the heating pad cover;
Remove the catalyst;
Insert a funnel for filling fuel into the opening of the container;
Make sure that the lever on the funnel is in the “lock” position;
Place the heating pad vertically and pour the required amount of fuel into the funnel. Move the lever on the funnel to the “open” position and the fuel will go inside the heater. If fuel overflows, wipe off the heating pad with a dry cloth or rag. To fill the heating pad completely, add 12, 24 or 36 ml. fuel for different heaters, which corresponds to 1, 2 or 3 funnels;
After refueling, reinstall the catalyst;
Turn the heating pad to a horizontal position and bring a lit match or lighter to the catalyst;
Warm up the catalyst for 10 - 15 seconds until the feeling of heat transfer to the metal case of the heating pad;
Replace the cover of the heating pad and place it in the cover;
When the heating pad cools down, repeat the filling and heating procedure;
To stop the heating process, remove the heating pad cover and carefully remove the catalyst using a thick cloth. He's very hot! Risk of burns on contact with skin! After cooling down, reinstall it. The hot water bottle will now run until you reheat the catalyst.

Today I want to tell you about one of my very old purchases.
A catalytic heating pad that I bought on ebay two years ago.
Now it is getting cool here, and I again began to use this useful thing. At the same time I decided to talk about her.
I'll start with a definition. Suddenly someone does not know exactly how catalytic heating pads work:

What is a catalytic heating pad:
This device is a chemical heating pad, the purpose of which is to individually warm a person with the help of flameless oxidation of high-purity gasoline vapors. Over the four years of the First World War, the inventors of England, Japan and the United States created several versions of pocket-type liquid heating pads. To start the device, the reservoir was filled with alcohol, which was absorbed into the cotton wool, after which the device was heated by the flame of a match - as a result of this, a catalytic reaction occurred. Today, a catalytic warmer for hands and heating other parts of the body has found wide application among lovers of hiking, fishing, hunting, and winter sports. She gained great demand in the conditions associated with working on the street. In the Soviet Union, manufacturers produced a gasoline heating pad GK-1, which, when fully refueled, was capable of generating heat for 8-14 hours with a temperature indicator of up to 60 degrees.
The principle of operation of a catalytic heating pad:
The catalytic heater device is relatively simple, because the device consists of a body made of metal, without additional external parts. In terms of size, most models are about the size of the palm of an adult man. A reservoir is located inside the housing, and a catalyst is attached to the neck. The latter contains cotton wool, which is soaked in gasoline. The neck is closed with a tight lid, but there are holes in it through which air flows to the catalyst.
The principle of operation of the device is based on the release of heat, which is accompanied by flameless oxidation of gasoline vapors in the presence of a catalyst. Gasoline vapors pass through a special catalytic cartridge. They are oxidized by oxygen on the surface of an already heated catalyst, i.e. these vapors burn out without a flame. Oxidation products escape from the instrument through the ventilation holes in the cover. At the same time, air containing oxygen begins to flow through them to the catalyst surface. The catalyst (catalytic gauze) is a platinum piece that looks like a wick - this is the most important component of the heating pad. Inside it is a steel mesh cartridge. To start the mesh in a catalytic cartridge, it must be heated for 10-15 seconds using a flame that does not give off soot, for example, a lighter. The fuel used for the heater is gasoline that has passed the highest degree of purification. The use of other types of fuel leads to rapid deterioration of the mesh - a phenomenon called "catalyst poisoning".

Ntthm after a short introduction, you can move on to the subject of the review.
I bought a heating pad on ebay. I bought on the basis of the “cheapest offer” principle. The link where I took it is no longer there, so in the header there is a link to the cheapest option that I found. Although it may be cheaper.
I, then as I remember, took two heating pads. One for myself, one for my father. Both heating pads work perfectly, they warm up.
At the time of arrival in the parcel, the heating pad was in the box, but it is clear that the box had not been preserved in two years. At normal times, the heating pad is kept in my felt bag, which was included in the kit. Here it is:

The heating pad itself is a metal remnant that slides very strongly in the hands. For two years of wearing it in a case, the heating pad did not fade in any way, did not get scratched and nothing happened to it. See for yourself:

And what will happen to her if she is always in a case?
For those who are interested, I will show the sizes:

The body of the heating pad is made entirely of metal. I can assume that this is stainless steel, but I could be wrong. The body itself is collapsible and consists of several parts: a lid, a nozzle with a catalyst, and a tank with cotton wool. In the photo you can see that the heating pad has been used many times, so the catalyst nozzle has traces of carbon deposits. But this has not yet affected the heating properties of the heating pad:

If you remove the catalyst, you can see cotton wool, which needs to be impregnated with gasoline or other flammable liquid:

For fun, I tried to remove the lid to look at the insides, and it took off. Before that, I had never looked inside. And inside there is ordinary cotton wool, laid in layers:

In the photo, the condition of the heating pad is everywhere after two years of not very frequent use in the cold season.
Now I'll tell you about how I use the heating pad.
As a flammable liquid, I use gasoline for lighters, which I buy offline at a price of 400 tenge (about $ 1.1) offline:

The heating pad also included a special filler funnel:

With its help, I pour gasoline into the heating pad. I usually fill in the first division of the funnel. Sometimes more.
Then I put the catalyst in place and set it on fire with ordinary matches:

In the description of the product, and in the instructions above, it is written that you need to heat the catalyst for 15-20 seconds. But in my case, it takes 2-3 matches to heat the catalyst. The faster the catalyst does not ignite.
By the way, in this photo you can see that the center of the catalyst is no longer heating up:

Most likely due to the constant touching of matches in this place, it is already spoiled.
After the catalyst has lit, it takes a few minutes for the heater to heat up. If you do not put it in a cover, then literally in 2-3 minutes the heating pad in your hands feels hot enough:

But the promised 60 degrees as in the Soviet KT-1, this heating pad is clearly not typed.
One refueling of a heating pad is enough for me on average for 4-7 hours. Depends on how much gas I poured in.
I use this heating pad in several versions. In the fall, at work, heating has not yet been provided, but the premises are already cool. I light the heating pad, put it in the cover, and put it in the back pocket of my jeans. The ass is warmed up, the heat goes to the lower back, and as a result, the whole body is warm.
Of course there is another option:

Heaters "Dobroe teplo"!
Our couriers will deliver them directly to your apartment in containers 0.5, 0.7 and
1 liter…

But not everyone at work has it.
Also, I always take this heating pad with me on winter fishing. No matter how good and warm clothes I stock up, the heating pad, which is in the inner pocket behind the bosom, gives a pleasant warmth, which heats very pleasantly. Moreover, I am opposed to the adoption of liquids for sugrevu fishing.
Based on the results of two years of use, I can safely say that this is a very successful purchase.
But now I would probably have better added money and bought an original Zippo heating pad. Here in this color:

According to reviews, the quality of these heating pads is much higher than that of Chinese ones. They contain catalysts made from a real titanium alloy, which is more reliable and durable. Well, plus the appearance is more interesting.
That's all. I wish you all warmth, in these already cool autumn days. Take care of yourself and your health. I plan to buy +60 Add to favourites I liked the review +92 +148

The catalytic heating pad is interesting because it can be used many, many times... With active use heating pad lasts for several years... They come in different shapes and colors, but the principle is the same for all catalytic heaters. For those who have never used a catalytic heating pad - this article will be very useful, and those who already have it will be able to find useful advice on prolonging the "life" of a heating pad.

So, what is a catalytic heating pad and how does it work. It is a small device that disassembled into three parts: reservoir, cap with catalyst and lid. The heater generates heat during the flameless oxidation of gasoline vapors in the presence of a catalyst. Gasoline vapors come from the reservoir and pass through the cap with the catalyst, where oxidation occurs on the surface of the already heated catalyst at a temperature slightly above 100 degrees, with heat transfer to the heating pad body.

How to refuel and what kind of gasoline to use for refueling.

When people hear about gasoline, everyone has a question: "How difficult is it to refuel a heating pad?" Actually heating padyou can refuelvery easy and neat... Any gasoline is suitable for her, but it is recommended to use only cleaned... First, it doesn't stink! Secondly, if you use regular gasoline, then this will significantly reduce the "life" of your heating pad. We use the cheapest refined gasoline for the heater - this is gasoline "Galosha"... You can buy it at any hardware store and it costs about 20 UAH.
The heating pad comes with a special watering can for easy refueling. You can use a syringe to accurately fill the catalytic heater, then the chances of spilling gasoline or getting your hands dirty are minimal. Gasoline syringe can be poured into a watering can or directly into the reservoir of a heating pad, as it is convenient for anyone. But if you get gasoline on your hands, then there is nothing terrible, just wash your hands with soap.

How to calculate how many hours to fill a catalytic heating pad

If you do not need the heating pad to keep warm all day, but only several hours then you should fill the heating pad at the rate of 1 ml for 1 hour of work... And add a few extra milliliters for stock.
If you want the heating pad to work all day, then fill it completely. How do you know if a heating pad is full? In the tank you will see a cotton wool, it is needed in order to retain gasoline. While dripping gasoline onto a cotton swab, turn the tank over from time to time. When the tank will be full, cotton wool will no longer be able to hold gasoline and you will see how gasoline is dripping from the tank... If, when you turn over the tank, gasoline flows out of it, then you have filled the heating pad completely. Wait for the gasoline to drain, close the heating pad.

If you are using a heating pad for the first time, then the catalyst must be "started".

Before starting work absolutely a new heating pad, the catalyst must be "started" for a better job. This requires a lighter, preferably a turbo lighter. We carefully take the cap with the catalyst with pliers (in the absence of scissors) and heat well on both sides over the fire. If you do not have a lighter, you can do this over the stove, but this must be done very carefully so as not to spoil the catalyst. It is not recommended to do this over a fire. since you smoke the catalyst and shorten its life.
There is no need to calcine the catalyst before the next use., it is enough to hold the lighters over the fire for 10 seconds.

What to do next?

After the performed operation, we put on the cap with the catalyst on the tank, on top of the lid... For better work, let's warm up the tank in our hands and through for a couple of minutes we already feel warm... Then we can put the heating pad in a pocket or in a mitten, put it in a case and hang it around the neck.

What is the heating temperature of the heating pad?

Hot water bottle can heat up to 60 degrees, but in this case it is worth keep in a case which is included. The heating temperature of the catalytic heater depends on the environment. If it is severe frost outside, then in your pocket the heating pad will be about 45 degrees. The main thing give the heating pad oxygen... If you put a heating pad in your mittens, then periodically pull it out, otherwise it will go out.
If you take a heating pad with you, grab a lighter to her. If the heating pad goes out, you turn it on again in less than a minute.

How to "turn off" a heating pad?

When oxygen supply stops, warmer stops working... You can close access to oxygenfor a few minutes andthe heating pad will cool down... Or you can remove the capwith a catalyst and hewill go out instantly... Only careful, the cap is hot!

What if there is no longer a need to use a heating pad, but the gasoline remains in the tank?

It must always be borne in mind that gasoline evaporates... If gasoline remained in the tank, then in a few days (depending on how much of it is left) he evaporate... So he evaporated more slowly, put on food(or construction) film on the tank where gasoline is poured. In order not to breathe in vapors (although they are insignificant, for example, on the street from cars the vapors are much stronger), put the heating pad in a cover, or even better on the balcony.

If you decide to purchase catalytic heating pad in our store, then we will deliver it in a convenient way for you, as well as provide detailed advice on the application! Order from us right now! Enjoy winter with us!

There are several different devices that are used for heating small spaces and for personal heating of a person. One of them is a catalytic heating pad, available on the market in a large assortment. A prerequisite for the creation of this compact device was the inconvenience experienced by soldiers during the First World War in the winter. Find out everything about this device: how it works, models and prices.

What is a catalytic heating pad

This device is a chemical heating pad, the purpose of which is to individually warm a person with the help of flameless oxidation of high-purity gasoline vapors. Over the four years of the First World War, the inventors of England, Japan and the United States created several versions of pocket-type liquid heating pads.

She gained great demand in the conditions associated with working on the street. In the Soviet Union, manufacturers produced a gasoline heating pad GK-1, which, when fully refueled, was capable of generating heat for 8-14 hours with a temperature indicator of up to 60 degrees.

The principle of operation of a catalytic heating pad

The catalytic heater device is relatively simple, because the device consists of a body made of metal, without additional external parts. In terms of size, most models are about the size of the palm of an adult man. A reservoir is located inside the housing, and a catalyst is attached to the neck. The latter contains cotton wool, which is soaked in gasoline. The neck is closed with a tight lid, but there are holes in it through which air flows to the catalyst.

The principle of operation of the device is based on the release of heat, which is accompanied by flameless oxidation of gasoline vapors in the presence of a catalyst. Gasoline vapors pass through a special catalytic cartridge. They are oxidized by oxygen on the surface of an already heated catalyst, i.e. these vapors burn out without a flame. Oxidation products escape from the instrument through the ventilation holes in the cover. At the same time, air containing oxygen begins to flow through them to the catalyst surface.

The catalyst (catalytic gauze) is a platinum piece that looks like a wick - this is the most important component of the heating pad. Inside it is a steel mesh cartridge. To start the mesh in a catalytic cartridge, it must be heated for 10-15 seconds using a flame that does not give off soot, for example, a lighter. The fuel used for the heater is gasoline that has passed the highest degree of purification. The use of other types of fuel leads to rapid deterioration of the mesh - a phenomenon called "catalyst poisoning".

Method of using a catalytic heating pad

It is possible to increase the efficiency of a device that has been clogged by calcining the mesh cartridge together with the catalyst in a muffle furnace or on a gas (non-smoking) flame. Remember that the use of individual catalytic devices in closed rooms is hazardous to health, because gasoline oxidation products are highly toxic. It is necessary to use a catalytic type heating pad in accordance with the instructions:

Place the device on a flat surface. If the weather is cold, then warm up the device before starting - for example, you can for 10 minutes. place it under your clothes.
Enter the required volume of gasoline for lighters or any other option that has passed the highest purification into the tank using a special watering can / funnel (included in the set). Please note that you cannot refuel the heater with gasoline.
Be sure to fix the watering can using a special clip. This approach will help avoid leaks.
Remove the watering can and put the catalyst in its place.
Make sure that there is no spilled fuel on the body of the device, after which you can heat it up with a match or a lighter.
The catalyst will heat up to the desired temperature in about 5-10 seconds.

For long-term use of this pocket device, it is very important to follow certain rules of care. The main thing is that before each refueling, it is imperative to shake out the remaining fuel from the tank. Over time, when the surface of the device becomes dirty, warm it up for 1-2 minutes. over the flame of a gas stove - this way you will restore the device to its previous state. This will bring the heating pad back to its maximum temperature.

During operation, the surface of the catalytic device is capable of heating up to 60 degrees. This temperature is somewhat high for contact with the human body, therefore, in addition to the device, the kit also includes a special bag - in it you need to hold the device. This kind of cover is also necessary to protect the device from cooling, because cold air may cause it to stop working due to insufficient fuel evaporation. Typical uses:

warm your hands by placing a heating pad in a mitten or keeping it in your pocket;
dry shoes by placing the device inside the shoe;
keep warm at night by placing the device in a sleeping bag.

Catalytic heating pad manufacturers

The final cost of a heating device depends on the country of origin and firm. On the market there are models of domestic production, Korean, Chinese, etc. High-quality models cost from 1.5-2 thousand rubles and more. Their difference from cheap counterparts lies not only in the quality of manufacture, but also in fuel consumption - they are more economical and at the same time emit less gasoline odor during operation. Well-known manufacturers of heating pads that are widely used by fishermen, hunters and travel enthusiasts include:

ZIPPO;
KOVEA;
