Ariston Fast Evo 11C

Advantages: 1. After installation of the column and mandatory adjustment by a specialist, there is always hot water in the taps. You don't need to do anything with the column. It ignites and extinguishes itself. There is no need to change the batteries - the electronics are powered from the mains. I rarely go to the column, only if for some reason I needed water of a different temperature. 2. It is not necessary to regulate the gas and water supply to obtain the desired temperature. This column does not have a thermometer reading on the display, but the desired water temperature set by the user. Using the buttons, I set the required temperature on the display, and the automation itself will select the required gas supply. If I wash in the shower, and someone turned on the faucet in the kitchen, or flushed the toilet, or for some other reason the pressure or water flow rate or gas pressure changed, then I don’t need to run to the water pump and adjust something there. You just need to wait a little - the automation itself will select such a flame power so that the water temperature returns to the value previously set on the display. 3. The column works reliably even at very low water pressure. 4. A properly configured speaker is very quiet.

Disadvantages: 1. The water temperature does not stabilize instantly, but fluctuates for some time either higher or lower than the set value. This disadvantage will take some getting used to. If the column is tuned correctly, then the oscillations quickly damp and the temperature is maintained with high accuracy. 2. Powering the electronics from the mains eliminates the need to change batteries, but requires an electrical outlet near the speaker. The column does not work without electricity.

Comment: To maintain the guarantee, the commissioning of the column must be performed by a specialist of an authorized Ariston service center. For the column to work properly, it must configure and write four parameters into the control unit memory: 1. The type of gas used. 2. Maximum power (so as not to overheat the radiator). 3. Minimum power (at which the burner stably burns and does not extinguish). 4. Power of smooth ignition (such that the gas is ignited reliably, but smoothly - without a pop). The instructions tell you how to correctly set these parameters by monitoring the pressure at the outlet of the gas valve using a pressure gauge. A certified "specialist" came to me without a pressure gauge, who had never seen such a column or instructions for setting it up before. Therefore, after the commissioning marks appeared in the warranty documents, I had to do the setting myself. It was not so quick to set up without a pressure gauge, but the result is good.

Advantages: Small-sized, quiet (compared to the previous "shaggy" year of production) It ignites itself quickly and after 5 seconds after opening the water, hot water is already running.

Disadvantages: When the water pressure changes, it does not quickly regulate the water temperature. But after the habit, this is not at all a critical problem.

Comment: I have been using it for almost 3 years. Be sure to install water purification filters in front of the column. In my region, there is a lot of rust in the water, and because of this, after a year of using the column, the water flow sensor failed. The column stopped lighting up when the tap was opened. The sensor was bought for 1500r and put the filter. It has been working properly for two years. In general, it suits and does not require special attention. I rarely go to her. Once I set the water temperature and that's it.

Advantages: Just a good speaker.

Disadvantages: The quality of the water flow sensor.

Comment: The water flow sensor is repaired in 20 minutes. It just demagnetizes. It is necessary to remove the impeller and run a strong magnet over it several times. After that, it works for more than 2.5 years. You also need to adjust the minimum and maximum flame. And then you will be happy.

Advantages: very fast water heating and almost silent operation, stylish and cool design

Disadvantages: no

Comment: We bought this model about a year ago in an apartment. It was installed by the master, since then we do not know any problems with hot water. In summer and winter, they are provided with hot water, there is enough volume for a small family with a margin, we recommend this Ariston boiler

Advantages: Well-known brand, laconic design, mains connection (no need to change batteries).

Disadvantages: The display does not reflect the actual temperature. Very noisy. Requires customization. Price.

Comment: The most important thing! This unit requires gas adjustment. So don't try to install it yourself. Call the foreman under warranty, they usually have permission to install gas equipment. Gas adjustment is required to set the temperature, otherwise the column will not work correctly. Plus, it must be under warranty, so all actions must be performed by specialists.

Advantages: Design, price, safety, convenient operation.

Disadvantages: for three years of use, they did not notice anything.

Comment: After the Russian speakers, just heaven and earth !!!! European quality is immediately felt. I really liked the display, even my mom can handle the controls easily.
