The Hibrew H7A Barista Pro Dual Boiler excels with a real big-barrel, double boiler, the pressure and temperature values can be adjusted, it has its own grinder, it uses a catering industry standard, so this is the full range of Hibrew's home range.
Hibrew H7A Barista Pro Dual Boiler - It's not that big of a face
The Hibrew H7A is a real big gun, the flagship of home lever coffee makers, a giga machine that satisfies everything. We have already tested something similar BlitzHome BH-CMM5 personally, which wasn't a bad machine, but then I wasn't as familiar with more serious coffee makers as I am now. In additionthe 3-year-old machine also disappeared from the market, so the Hibrew H7A has no opponents in this price range based on its parameters. That is,what the company put together on paper is amazingly impressive, and due to the lack of Chinese brand power, this is not reflected in the price in the form of tens or hundreds of thousands, as in the case of a Sage or a De'Longhi. I could have even mentioned an AVX coffee maker, and then I didn't mention the premium brands.
I expected a bigger box, so I was surprised its spatial extent is not so dangerous, although I wouldn't dare to use the adjective compact for it. 331x332x347 mm, which is not small, a Hebrew H10A, as a reference, as the prototype of the unit coffee maker, which is 260x230x320, so there should be room on the kitchen counter if you choose a Hibrew H7A Barista Pro Dual Boiler.
At this HUF 150-200 level the packing of accessories in the box is no longer very small, which would also be strange because, in principle, baristas working with serious expertise can be included in the picture. So the manufacturer wants to do them a little favor too Based on 58 mm catering industry standard in the case of a machine. The lineup is as follows:
- 1 pieces of 58 mm metal tamper
- 1 piece 58 mm portafilter
- 1 gram coffee scale
- 1 silicone portafilter holder
- 1 milk frothing glass
- 2 piece, non-pressurized coffee basket
- 1 magnetic coffee funnel (so that the coffee doesn't fall next to it and it's easier to use the WDT tool)
The accessories looked so high quality and heavy that I quickly threw them on the gram scale to see which one was which.
The all-metal tamper is 412 grams, while the portafilter is 555 grams, if I also put the basket in it. Everything is of high quality, not just the machine, which also looks good, and which reminds me of the miniature, single-lever solutions of La Cimballi machines from Mc Donald's. There is material in everything, there is no smell of saving, but of course certain parts cannot be made out of plastic. Such is the 2,8-liter, brutal space-sized water tank, the coffee bean tank and surprisingly, the cup warmer tray too, which is a bit of a disappointment.
It is important to clarify that Hibrew produces two types of maxi machines:
- it's cheaper the Hibrew H7 Barista Pro (single boiler)
- the more expensive the Hibrew H7A Barista Pro Dual Boiler (worth buying)
I had the latter, so you can really expect the maximum from this, in return you also need to have a minimum understanding of the art of coffee making.
What does this mean? The fact that you must be aware of what needs to be set up and how the errors can be seen. THE Hibrew H7A Barista Pro not only prepares coffee, but also grinds it, so when viewed from the front, the unit on the left, which also includes a portafilter holder, is a conical grinder, only this was integrated next to the lever coffee maker. It's to his right Spout opening using 58 mm standard and the steam pipe is located, and moving upwards is the control panel.
This is also interesting because the Hibrew H7A Barista Pro is very clever at hiding this when turned off. The touch panel that blends into the design comes to life when you turn on the device, similar to the Hibrew H13A coffee maker with milk frother. The controls are neatly arranged to the left and right, by definition, you can see the parameters of the grinder on the left, and the parameters of the coffee maker on the right. In the middle of the pressure display clock that completes the overall picture. Which really feels like it although this is the top model of the middle category, you can't take everything apart. For example, the left section has:
- switching on
- grinding for 1 serving
- grinding for 2 serving
There's a counter here that shows how long it takes to grind, but the Hibrew H7A Dual Boiler does not fully allow intervention in the process, as a separate grinder. You cannot change the size of the portafilter - that's right - you can't set grams and there is no continuous grinding either. however, the grinding time can be regulated. According to the manual, 1 serving is 13! - not that much, as you can see later - he uses 19 grams for two, which is completely incomprehensible. The standard is usually 9 and 18 grams for a 51 mm portafilter, but I have read about less than this - a 7,5 gram dose is also popular - but not so much about more. Fortunately, the gram scale is here, so you can measure it, it's just strange that you can't set it directly, but of course you can play with the grinding time. The grinding fineness can be changed by rotating the coffee bean container, the conical grinder can use 30 levels, espresso requires a value below 5. It has a powder blower, i.e. a pump suitable for blowing out coffee powder, there is no mention of grinding loss, and the container does not seal airtight either, which is a shame.
The controller on the right is also not overcomplicated, extracting one or two portions of coffee, and the flow time and temperature can be changed between 90-96 degrees Celsius. So, to summarize the above, the Hibrew H7A Barista Pro Dual Boiler lets you tease out the important parameters, you can get into finesse, temperature and pressure values as well. So I enthusiastically started "tweaking" things, let's see what I came up with.
Every coffee maker has some kind of boiler that produces hot water and steam.
The cheapest solution is a thermal block, you have no chance of finding anything else for up to HUF 100. The reason for this is that everything else is quite expensive. The problem with the thermo block is that its ability to retain heat is not good, in return heats the water quickly. There are many other problems - for example, it produces steam from water splashes, which is why the seed tube spits - but the biggest one is how hard it is with this solution to produce a uniform temperature, which the thermostatic design of the cheap machines puts on top of it with a shovel. The thermostat does exactly what the heating controller does at home: it turns on at a certain temperature point and turns off at another.
The Hibrew H7A Barista Pro Dual Boiler uses NOT a thermo block and NOT a thermostat, but (probably) 2 steel - possibly aluminum - boilers and a PID controller.
The property of boilers is that they serve as a kind of buffer tank, not only does the water pass through them, but they keep the liquid at a given, relatively stable temperature, which is controlled by a PID controller. Why are there two boilers in it? The reason is that for making coffee you need roughly 90-95 degrees Celsius, for steaming 120-130, so you have to wait continuously for the equipment to heat up and then cool down. Hibrew H7 Barista Pro it can steam and make coffee at the same time, which is a typical mainframe feature. Of course it is this is also only the upper part of the middle category, because this could be further enhanced with a copper boiler and other clever things, but only black belts could take advantage of this when drinking coffee.
The result of the above is that you have to push the water with two pumps at the same time, which can be both positive and negative.
Based on the fact that in these generally there is a vibrating pump - designed for use in the catering industry rotary pump they get - this is the cheaper solution and it cannot be connected to waterproofing. Have you ever seen water being poured into the plane in the Meki? Not very likely.
Not because they are connected to water resistance, all those intended for industrial use are like that. I read earlier that the part that breaks the most is the vibration pump, fortunately Hibrew has a service in Hungary and sells this machine, so it's not that big of a deal. The point is that in principle, everything is given to make a great coffee.
I uploaded the Hibrew H7 Barista Pro Dual Boiler 250 gram container of beans with coffee beans, and after turning it on, I noticed that while the coffee maker is heating up, the coffee grinder is already active, which is a smart move. I picked up the magnetic coffee funnel - dosing funnel in English - which is the best thing among coffee accessories, because it doesn't allow the coffee grounds to fall out, plus you can use the coffee needle in it, I loved it. I set the fineness to 3-4, which is roughly what I need for espresso, and then I ground the factory quantity. Do you know that the H2500A consumes 3000-2850 W - I measured 7? These more serious espresso machines are no slouch when it comes to performance.
I clicked the portafilter into the machine, then pushed down the first coffee, I didn't hear the pre-soaking - the pre-infusion – his voice, hmm, doesn't the machine know? The pressure display didn't even move, the juice turned into a pile of poop. I wonder what I messed up? What you need to know about the Hibrew H7 Barista Pro Dual Boiler is that there is no booster portafilter, so you have to have some understanding of coffee making, that is, puck prep – the process of preparing coffee – cannot be just any kind. It seemed that I messed up the plug, so I checked the single portafilter instead of the double portafilter, I paid attention to the cleaning and the plug.
And oops, the pointer of the pressure gauge crept up to between 9-12 bar, good crema, pleasant aroma, that's it.
Then I messed something up again with the double coffee basket and again the brew was not good. So I came up with the idea of halving the amount of grinding and filling it halfway, and the result was even better.
What stood out is that the coffee drips from the Hibrew H7 Barista Pro Dual Boiler after extraction, so there is no solenoid valve,
amit for three-way they also call me, it's a bit of a disappointment. Fortunately, OPV does, i.e. pressure compensator, in the name of safety. Then I found the scale, I started to measure how much the grinder grinds, 1 for 16,5 portion! grams - completely incomprehensible, moreover, the manual states 13 grams -, 2 servings are 22! grams came out instead of the factory 19. I felt it, and then my heart skipped a beat from a single shot that was elevated to a doppio instead of an espresso. I reset the settings but it didn't change so I started experimenting with the grind time to unlock things. What can be done? The grinding time of 9 and 13 seconds must be taken back approx. By 6 and 10 and everything will be fine.
Finally, I found the settings I liked, a sufficient amount of crazy coffee, I was finally able to keep the pressure stable between 9-15 bar, the taste was good, and so was the texture of the brewed juice,
steaming barista milk substitutes could come. I thought I would knock over the coffee maker, turn on the steam tap and print the coffee at the same time, AND IT COULD do both at the same time. So it really has two boilers, we can go on.

Solid, even steam came out of the Hibrew H7 Barista Pro Dual Boiler's steam generator, not sputtering like thermo block coffee makers that dispense steam like old men peeing with prostatitis. I'm still not a handy person when it comes to latte art, but The Bridge's barista latte frothed like a dream. I tried to draw nice pine trees for you, but let's just say that it's better if you don't see the end result, because I ended up with a maximum of tree stumps.
The Hibrew H7 Barista Pro Dual Boiler knows everything you need, the result does not depend on it, but on the person who uses it, but it does not help you either, the minimum knowledge is a mandatory element here.
Summary
I'm glad I got to try the Hibrew H7 Barista Pro Dual Boiler, though I felt a bit like I had to constantly improve my knowledge of the machine. What I regretted it does not have a solenoid valve, and so on drips his own tray, I would have gotten away with cleaning for that much. No pre-infusion, which surprised me how nor a pressure-boosting coffee basket, the machine does not help you make good coffee. You know, but the tennis match with Roger Federer doesn't start with Frédi explaining to you how to hit, right?
On the technology side, you get almost everything, what you might need, double boiler, coffee grinder, great control, 2,8 liter, never-ending water tank, very good tamper, milk frother, and I could list more. Besides beats the competition in price, but many people won't need it. The Hibrew H10A is a much more "beginner friendly" machine with almost the same skill and the coffee grinder adds more to good quality overall than the coffee maker itself, but it is not certain that combining them together is the right solution. But I don't want to take away the merits of the Hibrew H7 Barista Pro Dual Boiler, it knows almost everything you need, you just have to go after it in terms of knowledge.
What is a PID controller?
The PID (Proportional-Integral-Derivative) controller is used to precisely adjust the water temperature, which is crucial for preparing high-quality espresso. The controller keeps the temperature stable, minimizing fluctuations, thus avoiding overheating - burn – or too low – improper extraction – errors caused by temperature. In fact, not only coffee machines use PID control, but also, for example, drones for their flight. It is a mathematical model based on P, I and D values. Without going into more details, the point is that the model takes both past and planned future data as a basis and corrects fluctuations in order to maintain the temperature as stable as possible. In contrast, the thermostats they operate within preset temperature limits, that is, if it falls below the lower threshold, they are switched on, if it goes above, they are switched off.
