10 best accumulators for water supply

The hydraulic accumulator is a completely mechanical system. It has no electronics, and the increase in pressure in the circuit is provided by a membrane that pushes water and inert gas pumped into the tank cavity. But even 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. It turns on and starts pumping 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. For the home, this device is indispensable, 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 has happened in your house, be sure to pay attention to this product.

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 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 able to rust.

Any coating sooner or later loses its qualities, 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 does not have a paintwork. No, the paint that covers the tanks is non-toxic, and has all the safety certificates, but not even that is here.Everything is as clean and safe as possible.

The budget hydraulic accumulator is made of 1 mm thick sheet steel and coated with enamel on the outside. The tank is designed for 24 liters and maintains a working pressure of 8 atm. When it falls, a command is given to start the pump. The membrane is made of ethylene-propylene diene monomer and lasts a long time, despite the cheapness of the product. The model is suitable for both hot and cold water supply, since the operating temperature range is +1…+99 ⁰С. The connecting flange is made of stainless steel, which ensures a reliable connection and long-term operation.

The case is distinguished by high-quality welded seams and uniform painting. Users are satisfied with the simplicity and reliability of the model, but complain about the components. For example, the flange fixing bolts are made of mild steel, so the threads can be stripped easily if overtightened. Also, the connecting thread can be less than 1”, so an additional layer of tow is needed. Otherwise, the product is of high quality and significantly relieves the work of the pump in the water supply system.

The hydraulic accumulator has a vertical mild steel construction. The bottom connection of the pump is provided. The flange is made of plastic, therefore it is not subject to corrosion and sticks to the tank less, which means it will be easier to remove it when replacing the membrane. The ends of the legs are equipped with rubber pads that prevent scratching the floor and reduce vibration. The warranty for the product is 1 year, but the model lasts up to 10 years.

In the reviews, buyers note the high-quality assembly of the accumulator, the durable polymer flange and the reliability of the design. People with hypersensitivity to odors say that the water that has passed through the membrane does not smell of anything. It is convenient to place a vertical structure in a corner, for example, in a boiler room or bathroom. And the bottom connection saves usable space. But the model is only suitable for cold water supply, since the pear material deteriorates at elevated temperatures.

An expansion tank and a hydraulic accumulator are, in fact, a simple system. It does not have complex elements and functions, and many manufacturers simply do not pay attention to external aesthetics. If the tank is in a prominent place in your house, and there is no way to hide it, it makes sense to take an attractive appliance. But if it is installed in a separate room, you can forget about beauty. And we have just such a tank. It looks as simple as possible, but behind such simplicity lies real German quality, which manufacturers assure us about.

According to them, this is the best hydraulic accumulator made in Germany, but especially for the Russian climate. Joint production. That is, the workshops are located with us, but all the equipment and quality control are German. Whether there are any advantages in this is difficult to say. There are no negative reviews online about this product. Everyone notes that he copes with his tasks one hundred percent, and does not fail. True, there are two drawbacks. First, instability. The tank's legs are at right angles, making 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 installed in a country house, then it does not make sense to overpay. You can buy the smallest 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 need to be fixed to a wall or floor, and it 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 performance of the system. It prevents air pockets in the circuit, and also facilitates the work of the pump, which no longer needs to maintain a constant pressure in the system. The hydraulic accumulator does this for him, while not spending a single watt of your electricity.

The hydraulic tank with a diameter of 480 mm and a height of 852 mm has a more robust design and is welded in three parts. The middle one is distinguished by an increased thickness of the metal. Initially, the tank is set to a working pressure of 4 atm., which is regulated depending on the pump power. But the maximum load limit on the container is 10 atm.This makes the hydraulic accumulator the best for a cottage to push water to the upper floors where there is a bath or toilet. The model is suitable for private and industrial systems of water supply, heating, fire extinguishing.

In the reviews, buyers are satisfied that a large 100-liter tank takes up little space due to its vertical installation. The manufacturer claims that this model will last up to 10 years without replacing the pear. For some, such a hydraulic accumulator has been serving for 17 years. Often, it is he who is recommended by masters who install plumbing in a private house. Of the minuses - it is difficult to remove the plastic cone at the end, designed to connect a pressure gauge and check the pressure. Some even scratched the paint while trying to do it.

In most cases, expansion tanks and 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 through the installation especially carefully so that the tank does not tear out of the wall and 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 design in terms of stability. The tank has three legs at an angle. This makes it as stable as possible, and even if it is accidentally hit, 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 the installation and connection to the water supply of the house. The total height of the tank together with the bed is 90 centimeters, and the discharge valve is located in the upper part, which greatly facilitates the process of pumping air into the system.No shortcomings were found in this device, as evidenced by the reviews of both users and specialists in the installation of such structures.

This Chinese company produces many elements for water supply systems. Including hydraulic 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 installation in a house where the whole family lives, and hot water is used very often.

The hydraulic 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 pipes, and the installation should take into account the total weight of the device. Without water, it is about 8 kilograms, plus one hundred liters of water. The location of the valve must also be considered. It is located at the back of the tank, and you need to install it so that you have unobstructed access. You will rarely need to pump air into the system, but sooner or later the pressure will drop anyway, and you need to pump up the tank.

The huge accumulator has dimensions of 955x500x500 mm and holds 150 liters of water. This makes it suitable for use in a large house. Thanks to such a supply of liquid, turning off the light will not be a problem if someone wants to wash the dishes, go to the bathroom or water the beds. The increased volume of 150 l significantly reduces the load on the pump, reducing the number of starts.The stainless steel flange is corrosion resistant and can be easily detached from the tank when replacing the diaphragm. The hydraulic accumulator is suitable for interaction with all types of submersible and surface pumps. Connects to the system via a 1" threaded fitting.

In reviews, the accumulator is called the best in terms of price to volume ratio. Users note high-quality painting that will not peel off over the years. The owners also share that, despite the huge dimensions, the hydraulic tank fits easily in the caisson due to the vertical design. From the bottom there is a place for connection, everything is compact and convenient. But you can use the model only for cold water, since the maximum allowed temperature is +35 ⁰С.
