10 best hydraulic accumulators for water supply
Heating systems in private and country houses operate on the principle of a closed loop. This is when the water, heating up, begins to move, thereby filling the entire system. If you have a one-story house, and the boiler is installed on the same level with the circuit, there will be no problems. But the owners of two or more storey buildings are faced with the fact that hot water does not rise above the first floor, creating a traffic jam. As a result, this leads to the boiling of the liquid in the system and failure of the boiler or the entire circuit.
The same problems arise with the water supply, when the water simply does not rise above the first floor, since the capacity of the initial pump is not enough. A pump will help to cope with these tasks, and in addition to it, a hydraulic accumulator. This is a special expansion vessel that can significantly extend the life of the pump. The principle of operation, in a nutshell, is as follows:
- The pump pumps water into the water supply system, including the tank.
- The inert gas in the tank is compressed and creates the required pressure.
- As soon as you start using tap water, the pressure in the system drops.
- When the pressure drops below the critical mark, the accumulator gives a signal to the pump and it turns on, pumping water again.
Without a hydraulic accumulator, when the tap is opened, the pump will immediately start working, and the heating system simply will not have time to warm up the running water. Using the tank, when you open the tap, you get exactly hot water, and filling occurs only when the critical level is reached. Thus, the accumulator is not only a convenient, but also a practical item that allows you to reduce the load on the pump, and in addition, it protects the water supply system from water hammer that invariably occurs in a closed circuit when it is filled with liquid from the outside.
TOP 10 best hydraulic accumulators for water supply
10 Bison ZRD
The accumulator is a fully mechanical system. It has no electronics, and the pressure increase in the circuit is provided by a membrane pushing water and inert gas pumped into the tank cavity. But here it is not complete without electronics. For example, the system uses a special relay. When the pressure in the tank drops, the relay receives a signal about this, and it transmits it to the pump. He turns on, and begins to pump water into the tank.
It is the relay that is the weakest part of the accumulator system, and even the best devices fail sooner or later. Fortunately, replacing them is not difficult, and it is better to immediately buy a more expensive and high-quality option, like the one presented here. This is a relay from a well-known Russian brand, of the highest quality and at an attractive price. This device is indispensable for the home, as it serves for a very long time and does not require replacement for many years. Of course, standard relays also rarely fail, but if this does happen in your house, be sure to pay attention to this product.
9 Unipump 100L horizontal
The Russian company Unipump produces the best elements for water supply systems. All their products are of high quality and attractive prices. But you always have to choose what is more important to you: reliability and quality, or an affordable price. Before us is one of the most expensive accumulators, and its main advantage is the stainless steel used in the manufacture. Its peculiarity is that it never loses its protective qualities, and is not capable of rusting.
Any coating sooner or later loses its quality, and stainless steel itself is not subject to corrosion. Of course, the price of this device is high, even very high, but it should be borne in mind that you buy it once and for many years. In addition, it is as safe as possible, since it has no paintwork.No, the paint that covers the tanks is not toxic, and has all the safety certificates, but even that is not here. Everything is as clean and healthy as possible.

Water supply to a private house is not the cheapest pleasure. The whole system is very expensive, but some elements can be saved. For example, we have the cheapest tank in front of us, and this is the best way to save money, since, judging by the reviews, it copes with its main tasks perfectly.
Only 1200 rubles for a full-fledged hydraulic accumulator and an expansion tank with a volume of 12 liters. The tank mount is vertical, wall-mounted, and not very convenient. Fasteners are at the rear and installation can be difficult. Also, the valve is located on the top of the tank, and when pumping, you will have to climb there. All these nuances must be taken into account during installation, and do not hang the tank too high to the ceiling, so as not to block access to the delivery valve. Simply put, at the initial stage this device will be enough for you, and it is never too late to change it to a more expensive and convenient one, and it will not take much effort.
7 Aquarebot
A hydroaccumulator for water supply is an independent device that performs its own, specific functions. But to ensure the full performance of the system, it requires additional elements. For example, a relay that turns a pump on and off. It must be of high quality in order to ensure the flow of water in a timely manner, and not to drive the pump just like that. It is also required to monitor the air pressure in the tank so that the accumulator works properly. This requires a pressure gauge.
All this needs to be bought separately, but you can take this kit and not bother with the bundle at all. Here, on one 24-liter tank, everything you need is installed. The tank itself was manufactured by Unipump, and the automation and control sensors were manufactured by Aquareobot. Both companies are Russian, and have been cooperating for a long time, releasing systems of maximum compatibility. You don't have to worry about whether the elements fit together or not. Everything is as balanced as possible, and therefore, of high quality and durable. The tank is installed horizontally, and the pressure gauge, like the delivery valve, are located on the side, which allows you to monitor the pressure, as well as pump air without unnecessary problems.

The expansion tank and accumulator are essentially a simple system. There are no complex elements and functions in it, and many manufacturers simply do not pay attention to external aesthetics. If the tank is in a conspicuous place in your house, and there is no way to hide it, it makes sense to take an attractive outwardly device. But if it is installed in a separate room, you can forget about beauty. And in front of us is just such a tank. It looks as simple as possible, but behind such simplicity lies the real German quality, which the manufacturers assure us of.
According to them, this is the best accumulator made in Germany, but especially for the Russian climate. Joint production. That is, the workshops are located with us, but all equipment and quality control are German. It is difficult to say whether there are any advantages in this. There are no negative reviews on the network about this product. Everyone notes that he copes with his tasks one hundred percent, and does not fail. However, there are two drawbacks. First, there is instability. The legs of the tank are at right angles, which makes it wobbly. And secondly, the price. Exactly the same tanks, but exclusively of Russian or Chinese production, can be bought much cheaper.

The size of the expansion tank is selected depending on the average water consumption. The larger it is, the more often you can use water without turning on the pump, and the system does not have to heat running water and spend a lot of energy on it. But if you do not have such a need, and you rarely use water, for example, when installing in a country house, then it makes no sense to overpay.You can buy the smallest hydraulic accumulator that will cope with its tasks no worse than its larger counterparts.
Before us is the smallest expansion tank with a volume of only 2 liters. It does not require anchoring to a wall or floor, and adheres perfectly directly to the pipe. Of course, he will not be able to give out a large amount of hot water, and the main function here is to ensure the safety and operability of the system. It prevents the formation of air pockets in the circuit, and also facilitates the operation of the pump, which no longer needs to maintain a constant pressure in the system. For him, the hydroaccumulator does it, while not spending a single watt of your electricity.
4 Unipump 100l. (stainless steel)
Almost all expansion tanks and accumulators are made of ordinary steel, on which thermal paint with polymers is applied. There is nothing wrong with this, and all dyes pass the necessary certification. But, as you know, nothing is eternal, and any, even the best paint, sooner or later loses its qualities, and bare steel begins to rust. Of course, this will happen very soon, but if you want maximum service life, then be sure to pay attention to this device.
Its main advantage is the material from which it is made. It is high grade food grade stainless steel. It does not rust and does not peel off. It should be understood that this is not paint, nor is it chrome applied to the surface. The entire tank is made of stainless steel, therefore, it simply cannot rust. In addition, stainless steel is as safe as possible for health. Yes, ordinary tanks also pass the necessary certification, but safety is never superfluous. This is the best option if you have children and you use water from your home water supply to prepare your meals.

In most cases, expansion tanks and hydraulic accumulators require complex installation. If we are talking about mounting to the wall, and a rather large tank of 80 or 100 liters, you need to think over the installation especially carefully so that the tank does not rip out of the wall and it does not fall. With this model, there will be no such problems, since it does not require installation, and is installed on the floor. This is the best construction in terms of stability. The tank has three angled legs. This makes it as stable as possible, and even if you accidentally hit it, it will not fall.
The inlet is at the bottom. The distance from the floor to the entrance is 40 centimeters. This is quite enough to carry out installation and connection to the water supply at home. The total height of the tank together with the frame is 90 centimeters, and the discharge valve is located in the upper part, which greatly facilitates the process of pumping air into the system. The disadvantages of this device were not found, as evidenced by the reviews of both users and specialists in the installation of such structures.
2 LadAna 100l.
This Chinese company produces many elements for water supply systems. Including accumulators of various capacities and capacities. Before us is one of the largest expansion tanks with a capacity of one hundred liters. This is the best option for a family home and hot water is used a lot.
The accumulator operates at a minimum pressure in the circuit of 0.2 atmospheres and this is the best indicator, since the pump resource is saved as much as possible. Installs the tank on the floor, vertically, or on a shelf at the highest point above the water supply pipes, and the total weight of the device should be taken into account during installation. Without water, it is about 8 kilograms, plus one hundred liters of water. The location of the valve should also be considered. It is located at the back of the tank and must be installed so that it is easily accessible. It will not be necessary to pump air into the system often, but sooner or later the pressure will still drop, and it is necessary to pump up the tank.

Accumulators, as a rule, have only one type of installation.They are either horizontal or vertical. But there are models that you can install at your discretion, depending on the type of contour and the characteristics of the room. Before us is just such a device from a well-known Russian manufacturer. Here, at the junction of the device with the water supply system, a splitter is installed.
The tank itself has no fasteners, that is, it does not need to be fixed to the wall. It rests on pipes, and since its volume is only 5 liters, this is quite enough to keep the tank stationary and not create a load on the circuit. The inlet valve is equipped with automation from another popular brand Aquarebot. It has long established itself on the market as a reliable and durable system that very accurately determines the pressure in the pipes. It is the automation that will turn on your pump when the pressure in the expansion tank drops.
