DIY vacuum heating radiator

A functional heating system is crucial for keeping our homes warm and comfortable during the winter. A popular technique for effectively heating a room’s air is the radiator. Traditional radiators, however, can occasionally be inefficient, resulting in uneven heating and increased energy costs. Fortunately, a do-it-yourself remedy called the vacuum heating radiator is becoming more and more well-liked.

Now, describe a vacuum heating radiator in more detail. It’s basically a vacuum-operated, modified version of a conventional radiator. This means that radiation is used in addition to convection to heat the air, resulting in a more uniform distribution of heat throughout the space. It can also heat up faster and maintain a constant temperature because it runs on a vacuum, which will ultimately reduce your energy costs.

Although it may seem impossible, building your own vacuum heating radiator is actually fairly doable with the correct equipment and knowledge. You can make a heating solution that keeps you warm and lessens your carbon footprint by following a few easy steps and using easily found materials.

The affordability of DIY vacuum heating radiators is one of their key advantages. Constructing your own radiator is far less expensive than buying a new heating system or paying a professional to install one. You can also customize it to fit your unique requirements and tastes because you have creative control over the design and materials.

Materials Needed Steps to Follow
Vacuum cleaner 1. Turn off the radiator and let it cool down. 2. Attach the vacuum cleaner hose to the radiator. 3. Turn on the vacuum cleaner and move it along the radiator"s surface to remove dust and debris.

Vacuum radiator. The true truth and shameless lies.

Using a standard heating radiator, lower the pipe so that it passes through the entire radiator, add a small amount of ethanol solution or lithium-bromide salt to the radiator, then pump out air to lower the internal pressure. You were given the so-called "vacuum radiator," which operates on the "heat tube" principle and is the subject of numerous online debates.

Through a pipe that is inserted into a radiator, hot coolant flows. When the radiator working fluid comes into contact with the pipe’s exterior, it rapidly evaporates and condenses on the interior of the radiator ribs. Thermal energy moves quickly from the coolant-filled pipe to the radiator’s interior surface.

At low temperatures, the working fluid evaporates because of the decreased pressure. The steam condenses on the radiator’s inner wall and returns to the coolant pipe to touch it once more.

The temperature differential between the inner and outer surfaces of the pipe’s steel wall determines how much heat moves through it. The heat flux is significantly higher when the outer wall is continuously cooled by a working fluid than when it is in contact with the air.

Liquid evaporation causes a significant quantity of thermal energy to be absorbed from the pipe’s surface. This appears to explain a seemingly paradoxical fact: the coolant-filled pipe’s high heat transfer despite its small surface area.

Based on the aforementioned analysis, it is reasonable to conclude that even the smallest fracture in the radiator’s body, or breach of integrity, will cause the internal atmospheric pressure to return. As a result, the working fluid’s boiling point will rise and either no steam will form at all or very little will.

The use of this miracle radiator, according to persistent advertising, saves money and improves the effectiveness of any heating system. Here’s why the statement is more than questionable:

Transfer of heat. First off, some manufacturers’ certificates of conformance contradict paragraph 5.4 of GOST 31311-2005. which states: "Deviations of the heating device’s nominal heat flux value from the manufacturer’s declared value should be within the range of minus 4% to plus 5%."

Given how unstable this vacuum radiator parameter is, it makes sense. For instance, Wikipedia states the following regarding the "heat pipe" request:

Possess a limited range of effective use. The entire coolant may turn into steam if the predicted temperature is higher than that, which will cause the tube’s thermal conductivity to drastically drop (by up to 1/80). Conversely, at low temperatures, the liquid evaporation is poor.

There is very little information available on the Internet about vacuum radiator testing protocols to ascertain heat transfer, with the exception of this document. To encourage more clicks on the image, I provide a diagram that I cite in the figure. (Reproduction)

As you can see, the temperature of the coolant and its flow—that is, the rate at which water moves through the pipe—have a significant impact on the radiator’s ability to transfer heat. Here’s how this is explained:

A phase transition corresponding to intense condensation and evaporation of the lithium-brown mixture within the radiator is linked to sharp increases and decreases in heat transfer.

Therefore, it’s either not true or it’s difficult to plan for the use of automation given these erratic qualities. Given this instability, it should go without saying that even identical radiator copies will differ in certain ways.

Rapid heating of the radiator’s surfaces while continuous broadcasting of advertisements makes up nearly the entire case for its efficacy, even though there isn’t much of an impact. Radiators are not the only part of the home’s heat engineering plan. These are still floors, walls, and furniture, all of which are composed of a specific mass with a large heat capacity.

You must heat not just the air but also this entire mass in order to increase the indoor air temperature by even one degree. The entire mass receives thermal energy from the heated air produced by the radiator, which is not isolated from it. Furthermore, this does not occur instantly. Thus, very little determines how quickly the radiator will warm up after turning on—it may do so in a matter of seconds or minutes.

A tiny quantity of coolant. Remember to promote the argument in question. However, after giving it some thought, this is once more not a case in support of the vacuum.

You only need to compare the amount spent on coolant and radiators—both of which are sold at amazing prices—if we are discussing a country home where the owners are compelled to use non-freezing liquids that they bought. It is typically more profitable to purchase non-freezing.

Normal water is typically used as a coolant in private homes with permanent residents. Talking about any kind of savings is absurd by definition because water in wells, rivers, and streams is unmeasured and free.

Typically, those who oppose assert that a smaller coolant volume will warm up more quickly than a larger one. It obviously refers to a summer home where the owners frequently show up during raids. As soon as I got there, I turned on and felt comfortable. It never occurs immediately. The coolant needs to be warmed up first. Second, you can’t expect comfort until the coolant has been heated enough to warm the air as well as a variety of walls and ceilings. This will operate with the same efficiency using standard radiators.

What more is broadcast advertising? The majority of resources advise saving twice. Moreover, the most fervent pledge and 4. Already, this is a blatant lie. If you remember the law of conservation of energy and that heat loss should be fully replenished, then nothing further needs to be proved. The radiator merely translates energy; it doesn’t create any. Furthermore, there are no savings from the remaining previously stated arguments.

Among other things, if there is natural circulation available in a private home with a heating system, it should be given more careful thought. In a system like this, the coolant moves very slowly because of gravity alone. (This situation poses a significant challenge to a vacuum radiator’s ability to operate.) Additionally, this pressure will be less than that of regular radiators.

It’s easy to understand why. This is a plan using standard radiators. The size H, which establishes the separation between the boiler’s and radiator’s centers, controls the pressure. More precisely measured, this is the separation between the radiator and boiler’s locations of water that is the same temperature. The gravitational pressure increases with this distance. Continue reading.

And this is a vacuum radiator circuit. The fact that the distance H is smaller here is very evident. Consequently, the downward gravitational pressure. Consequently, this lowers the system’s overall effectiveness.

Lastly, some real-world examples of vacuum radiator applications from consumers rather than dealers are allowed. These are some examples that are taken from here.

Dahnik: Alright, so I purchased an 8-section as a sample. Unfortunately, heat transfer is not 1 to 1, but rather about 70% (i.e., the pipe is significantly warmer than the radiator itself); either that, or I was unlucky and the Chinese there failed to report anything regarding bromine; or, still another divorce. or perhaps in its entirety. Furthermore, there was a continuous crackling sound, despite the seller’s assurances that it was just the old structure’s batteries crackling on some dry powder.

Suneco: Hi to all of you! I purchased an eight-section vacuum radiator and ran an experiment. Initially, eight sectional aluminum radiators were submerged in water. A 1.6 kW electric heating element with a thermo-rell that reached 80 degrees was screwed into the radiator, and the device’s measured operation and energy consumption were connected. a thermometer was installed in a shower booth, the electricity was turned on for an hour, and the process was repeated using a vacuum radiator.

Difference in temperature: 16 °C at 782 Wand 7 °C at 356 W In conclusion, physics cannot be tricked. Install a vacuum radiator on heaters, such as those made of aluminum. Equal routes are given to us.

Site exploration. It is possible to modify the search term.

Not to be overlooked is the second example. After an hour of operation, the vacuum radiator used half as much electricity as usual. but even though the relay was set to 80 degrees, it heated the room twice as much! What’s wrong? inadequate heat transfer. Additionally, two vacuums must be inserted to achieve the same heat transfer as in the case of an aluminum radiator.

As you can see, saving doesn’t really work that way. Furthermore, by paying a hefty price for a vacuum radiator, we incur unnecessary costs.

Vacuum heating radiators: available, effective, high quality

Because of the climate in our areas, the majority of financial resources are allocated specifically to ensuring a comfortable standard of living. You can cut your heating expenses in half by using a vacuum heating radiator.

The radiator’s appearance

Acquaintance with a vacuum radiator

The primary benefit is that only the lower portion of the battery receives heated water, or coolant. A vacuum containing a toll mixture fills the remaining space in the section.

There are only 0.05 liters of coolant in one section of this type of radiator. It is 0.35 l when compared to the volume of the aluminum battery.

A minor conclusion that emerges from the above is that it is easier to heat something with a smaller volume because less heat is required to bring it to a temperature. The mixture in the battery’s vacuum space boils at a temperature equal to plus or minus 35 degrees Celsius. This characteristic causes the radiator to heat up completely very quickly when coolant enters the lower section.

Using a thermal imager, compare cast-iron (right) and vacuum (left) batteries.

We also note that air traffic jams, pipes, erosion, and erosion in general, as well as the resulting heat transfer coefficient, frequently occur in the simplest systems. In this instance, it takes a long time and a lot of coolant to accelerate the heating system.

Vacuum heating radiators effectively address the aforementioned issues.

They will function from a variety of heat sources and will be an amazing substitute for standard, antiquated heating radiators:

  • Stoves;
  • Natural gas;
  • Electricity;
  • Boiler;
  • Solar manifold and pr.

Vacuum radiators and solar collectors


The following benefits are obtained by the owner when using such a radiator:

  • A decrease in the number of heating for heating by at least eighty percent;
  • Reducing the use of heat by counters from central heat supply by more than double. During the operation of induction boilers, saving electricity by thirty to forty percent;
  • Simple installation, it can be performed even with your own hands;
  • The impossibility of corrosion in the sections of the battery, as well as the absence of problems of importing;
  • Small local resistance during the circulation of the coolant through the entire heating system;
  • High level of heat transfer.

Security of vacuum batteries

When purchasing heating equipment, attractive design and excellent heat transfer are typically the main considerations. Questions like life and safety are pushed to the side.

People start worrying about safety and life only after the radiator breaks and gives unpleasant surprises. Because of this, leaks on plugs, footballs, and other objects could occur, resulting in monetary losses (which are not insignificant). People don’t start paying enough attention to the device’s safety until after such incidents.

Counseling! We suggest that you save time and money by carefully examining the features of the devices before making a purchase. To assist with this, each device comes with operating instructions.

The following factors contribute to such devices’ safety:

  • There are no Maevsky cranes in the radiator, gaskets, freezes, plugs, nipples. The battery has only two threaded connections that serve to connect the device to the heating system. The possibility of depressurization on a threaded connection is practically excluded;
  • In the heating device, the minimum volume of the secondary coolant, which exactly depends on the model. If the radiator fails, then there is no flooding;
  • The hydrostatic pressure in the device is only in the through metal pipe, the latter provides the passage of the coolant through the battery. The pressure in the battery at the secondary coolant of ethanol and at a temperature on the surface of the device fifty degrees is 0.29 atmospheres, at sixty degrees – 0.47 atm. and seventy – 0.78;
  • The process of depressurization will entail only the failure of the device and nothing else.

Installation of batteries with your own hand

Installing a vacuum heating radiator is a simple task that can be completed by hand.

In order to accomplish this, we will bring to your notice a rough plan of action:

  • If the reconstruction of the heating system is performed and the radiators must be replaced, then the first thing is the old. First you need to drain the entire coolant from the heating system;
  • Make markings for fasteners of new heating devices;
  • We attach the bracket to the wall and fasten our vacuum heating device to it. Pay attention to the quality of the installation of the bracket, it must be securely fixed;
  • The next step will be the installation of ball valves and connecting pipelines. By mounting taps, it is better to use dad and sealant;

  • The last step is to check all our work done for tightness.

What will be needed to perform installation work

To perform installation tasks on your own, you will require the following equipment:

  • Roulette;
  • Pencil;
  • Building level;
  • Set of rye keys;
  • Passatigi;
  • Hammer drill.

Crucial! Please do not use sandpaper, files, or other similar instruments to clean the connected surfaces in the future. Poor sealing may result from their use.

A vacuum radiator is the perfect heating appliance for any kind of space. In addition to being inexpensive and dependable when in use, they also don’t require any specialized installation knowledge.

How to choose a vacuum heating radiator. Vacuum heating radiators: reviews

February 21, 2015.

Before the heating season begins, we’re all considering installing more contemporary, and thus more efficient, equipment. Yes, it is better if the radiator heats the space as effectively as possible. Installing a more powerful boiler will often enable you to adequately heat your entire home or apartment. However, installing a vacuum heating radiator is an alternative solution. This gadget works by decreasing the amount of heat that escapes the room through the pipes and radiators.

Do you want to increase the effectiveness of your home heating system while saving money? DIY vacuum heating radiators are one idea. These radiators use less energy and more efficient heating than traditional models because they use vacuum technology. These are reasonably priced heating and insulation options that are simple to install at home with the correct equipment and supplies. Furthermore, you can alter the size and style of DIY vacuum heating radiators to suit your unique requirements and aesthetic tastes. These radiators can contribute to your comfort and energy savings by evenly distributing warmth throughout your house with proper installation and upkeep.

A little about the device

We can say that a vacuum heating radiator is not a revolutionary discovery. It has been known for a long time, another thing is that popularity has gained popularity only in recent years. The device is quite simple. In appearance, we have a regular sectional radiator, but not water is used as a coolant, but a lithium-bromide solution, which begins to boil at +35 degrees Celsius. To maximize the pressure in the system, it is necessary to completely remove the air from there, hence the name – vacuum. In the lower part of the radiator, water flows, which does not contact with the coolant. Contact these liquids through the wall of the metal pipe. It turns out that the water warms the coolant, and he quickly gives heat to the walls of the radiator.

In details about the principle of action

Since we have already met a little with the design, I would like to better deal with the operation of the device better. So, hot water comes from the system, which transfers heat to the lithium-brimmer solution. Due to the low boiling point, it quickly evaporates, then the condensate flows down and again turns into steam. For this simple reason, intensive cooling of the lower pipe wall occurs. The temperature difference contributes to the fact that the heat flow increases. From all this it follows that vacuum heating radiators have advantages such as heating speed and high heat transfer. In addition, for a radiator of 10 sections, only 0.5 liters of solution are enough for efficient operation. To achieve the same effect, it is necessary to pour 4, and in an aluminum radiator, approximately 3.5 liters of liquid, in an aluminum battery.

To whom this heating method is suitable

In most cases, it makes sense to think about buying radiators of this type in the country or in a large country house. This is due to the fact that in rooms with a large area it is necessary to heat a large amount of coolant to high temperature. And vacuum heating radiators can significantly reduce heating costs. Moreover, the room will bask much faster. In addition, radiators have several sensors. Когда будет достигнута нужная температура, они сами отключатся, а котел перейдет в режим ожидания. What else is interesting: completely any boiler is suitable. It doesn’t matter if it works on solid or liquid fuel. Of course, one cannot say that such batteries do not have their own nuances and shortcomings, they are. But we will talk about this a little later. Now let"s deal with the choice.

How to choose a vacuum radiator?

Before buying, it makes sense to pay attention to the quality of the product. We can say that the liquid used as a coolant is poisonous. Therefore, you should not have any contact with her. In order not to be mistaken, pay attention to the quality of the assembly, connection and tightness. Of course, the last moment is very significant, and it is almost impossible to determine it by eye, but when testing the system, everything will immediately fall into place. In principle, the number of lithium bromide plays the role. There should not be too many. To check this, take the radiator in your hands and try to rock it. If you hear only a small rustle, then everything is in order. When is the transfusion of fluid, this indicates its excessive amount. Do not forget that vacuum heating radiators, the principle of operation of which we have already considered, should be completely tight.

Vacuum heating radiators: consumer reviews

Statistics show that a lot of people favor alternative heating methods. There’s a simple explanation for this: a vacuum radiator may leak. She might not seem like much, but she is. Yes, you agree that a device like that shouldn’t be in a child’s room. Is it advantageous if the case’s gap is found right away, and if not? The outcomes might not be optimal. Some prospective customers claim that this is possibly the biggest disadvantage.

But there are those who are extremely positively speaking about such radiators. Many say that this can significantly save on average 20-40% of electricity. You can believe it, because the boiling temperature of the coolant is quite low, and its heat transfer is at a high level. In addition, there are responses regarding the appearance of the slightest crack in the case. You can be sure that in this case it will quickly become cold in the room. Depressurization will lead to the fact that the system will have atmospheric pressure, and this, in turn, will increase the boiling point of the coolant. In principle, these are all the advantages and disadvantages that, according to users, are vacuum heating radiators. The reviews, of course, largely depend on the manufacturer.

About Energyeco

It is safe to say that these are the most well-known vacuum radiators produced in Russia for heating purposes. The company produces 1.5 mm thick carbon steel devices. At a working pressure of 0.6–1.3 MPa, one section’s approximate heat transfer is 170 kW. The product is capable of withstanding pressures up to 2 MPa in theory, but at 5 MPa it is annihilated. Customers hardly ever leave negative reviews for Yenerjouko products; instead, they are all compliments on the excellent assembly.

This is not to suggest that you will pay a low price for such a pleasure. Hence, the total cost of a 12-section battery is 550 euros, or roughly 300 euros for a six-section battery. Nevertheless, despite this serious disadvantage, people still purchase electric vacuum heating radiators to heat offices and commercial buildings in addition to flats and country homes. Since they are significantly less expensive than cast-iron and aluminum radiators, they are very popular, as was already mentioned.

Install a vacuum heating radiator with your own hands

It is quite possible to survive on their own if there is no desire to pay experts money for the assembly. Even though you lack real-world experience, theoretical knowledge is still preferable. Nothing complicated is going on here; everything is done in a few easy, steady steps.

First you need to dismantle the old heating system, unless, of course, you have done this yet. To do this, the coolant is pre -drained. After applying the fasteners for vacuum radiators. Set the brackets and check them for stability and strength, and only then hang the battery. If suddenly the mount does not withstand, the radiator can fall and damage. At the next stage, ball valves are sealed. To do this, you can use the usual sealant. The main pipeline must be connected to the taps and re -seal the system. Please note that during the cleaning of the joints it is impossible to use abrasive. This is due to the fact that in the system metal particles are a danger to the pump and seals. At the last stage, the coolant is poured into the system.

On the advantages and disadvantages of vacuum radiators

The majority of these devices’ benefits have already been discussed. A vacuum radiator, for instance, can run on gas or coal in addition to firewood. Innovative solutions like solar batteries and t, along with electric power sources, are not an exception. P. In addition, the system’s water content is drastically decreased—by roughly 70%. It is only required to warm the coolant. Furthermore, you can permanently disregard the existence of air traffic congestion and radiator rusting. The majority of manufacturers claim that their devices are 98% efficient and have a service life of roughly 30 years.

You are undoubtedly curious as to why vacuum heating radiators are not that common in Moscow and many other Russian cities. It’s all about how expensive they are. Nonetheless, this kind of indoor heating is highly common in Europe, where radiators are scarce.

For homeowners hoping to save money on heating expenses and increase energy efficiency, switching to a do-it-yourself vacuum heating radiator system can be a wise choice. You can make sure that heat is distributed efficiently and uniformly throughout your house by clearing the air out of the radiators. Over time, you may save a lot of money on your energy bills with this straightforward yet efficient solution.

The comparatively low cost of a DIY vacuum heating radiator when compared to other heating system upgrades is one of its main advantages. Homeowners can save money on installation costs by doing this project themselves with simple tools and supplies. Additionally, you’ll see a return on your investment in the form of lower heating bills thanks to the system’s increased efficiency.

Additionally, DIY vacuum heating radiators give you more control over the heating system in your house. You can guarantee that every room has even heating by getting rid of air pockets in the radiators. This will prevent cold spots and increase overall comfort. This degree of control makes your home more environmentally friendly and sustainable while also improving your quality of life.

It’s crucial to remember that although many homeowners can install a DIY vacuum heating radiator system, it does involve close attention to detail and adherence to safety precautions. In order to sustain the vacuum and guarantee peak performance, the system must be sealed properly. Furthermore, seeking advice from experts or consulting reliable guides can offer helpful direction all through the installation process.

To sum up, DIY vacuum heating radiators present an economical and effective way to enhance residential heating systems. These systems improve heat distribution, boost energy efficiency, and offer more control over indoor comfort levels by sucking air out of the radiators. For homeowners looking to upgrade their heating systems, the installation may require some do-it-yourself expertise and attention to detail, but the long-term advantages make it an investment worth doing.
