Bosch WRD 13-2G

Advantages: It looks like high-quality components inside the column, neat assembly
Stable operation of the column itself, well maintains the set temperature
Easy and accurate adjustment of water temperature, the presence of the display
Water up to the set temperature smoothly, without jumps
There is no constantly burning fire and no need to change batteries.
2 years warranty, but with mandatory maintenance after one year

Disadvantages: Noisy hydrogenerator: whistles like a strong draft. A bit annoying, but generally tolerable. In studios and living rooms can be a problem. When water is turned on next to the column, it is almost inaudible. The column itself runs almost silently.
Capricious to pressure and water pressure. At 2.4 bar and 4 l / min barely started. It is necessary to open the second valve - goes out. Battery version, they say, less capricious.
Design and pens seem to be borrowed from Soviet household appliances. The display and the power button hang crooked, because in the new model, the electronic unit is smaller than the previous one, plastic is easily soiled.
The service life, according to the master, is 3-5 years. Repair almost senseless, because any node costs at least 1/3 of the cost of a new column plus work, and when the next one fails, you will not guess.
Column open bottom

Comment: In general, satisfied with the purchase. But it was worth all the same to take 10 liter and on batteries. She, though without a display, but less capricious to the pressure of water.
Of the closest competitors, he thought long over Ariston Gi7S, because it looks better and is easier to manage, but was afraid of the Chinese assembly and the closed combustion chamber, it is possible that nothing. From Vaillant refused because with the same parameters and service life, the price differs twice. Neva 6014 upset temperature fluctuations when turned on.
From the relative advantages of this column: the heat exchanger is not beautiful. It does not affect the service life, since corrosion comes from the inside, and it is easier to solder the fistula - no need to clean the paint :)

Advantages: Easy to use, appearance.

Disadvantages: It does not always turn on with low water pressure (when the water filter is clogged at the inlet), there is no protective (decorative) casing from the bottom

Comment: I use 1.5 years, in general I am satisfied. When installing, it was warned that after a year it is necessary to carry out maintenance to extend the warranty for another year. I do not carry out maintenance. missed the moment, it has been 1.5 years, now it will not be prolonged ... The neighbor has had a similar column without maintenance for 5 years already ... He took another 13t.r,

Advantages: size, lack of electro-dependent parts, modern functions

Disadvantages: generator sound

Comment: An unpleasant surprise was the buzz of the hydrodynamic ignition motor. If the old column was noisy with gas and water, and with all the usual things passing through the pipes, and with the flame itself, then this one seems to be noisy with water or flame, BUT whistles the engine of the turbine.In the conventionally distant room with the doors to the kitchen open and the bathroom door closed, I hear not so much the sound of the water of a washing person as the whistle of this unit.
The rest of the unit is not bad. True miracles from the maintenance of a given temperature on a small head of water were not expected - there was no disappointment)

Advantages: A good machine, the water heats quickly, it works quietly

Disadvantages: Not accurate support for a given temperature, that is, for example, set the temperature at the maximum open tap at 40 degrees, reducing the water flow by the tap, the temperature drops to 35 degrees. and vice versa.

Comment: The device is still not long enough (7 months) to judge its reliability, but so far the norm. The design inside is externally hlipkovat, many plastic parts and assemblies, hydraulic connections are movable, all on rubber rings, do not look reliable. His predecessor, the Neva 4510, lived for 5 years, let's see how much better Bosch.

Advantages: It just works - it lights up on its own, turns off on its own, warms enough. Wonderful, useful and convenient device.

Disadvantages: Sensitive to gas pressure. Inconvenient arrangement of inputs / outputs, traditionally (for Bosch) vague description of the connection in the instructions.

Comment: Pre-purchased all the adapters and stuff. He took off the old Neva-3212, and in its place stuck this one, right on the same pins in the wall. With the fact that where to connect, I slowed down for a long time - I chewed instructions, looked at the insides of the column ... As a result, I came to an unequivocal decision and connected. It worked right away (taking into account the reservation in the instructions that it is necessary to turn it on / off several times so that the gas passages are completely filled with gas), but at first it was very disappointed with the power. Everywhere they write that it is suitable for at the same time 2 water consumers - this is not so, there is not enough water pressure. Yes, what is there, and for one it is difficult enough, because for satisfactory heating of water (with some reserve) it was necessary to completely turn on the water flow reducer and open the gas to full.
But in the course of operation, over the course of the next few days, it turned out that what the column gives is enough with the head, since in winter the water warms up to 55-60 degrees, and if you reduce the pressure, then everything is 75. Then cold water to taste, and as a result a normal pressure with warm and hot water is obtained.
However, in early spring the pressure of the gas dropped several times, which is why the column heated up to a maximum of 40-45. Then I climbed inside and slightly "corrected" the mechanics of the gas valve. It began to work a little better, but after a couple of months it suddenly began to "explode" when turned on. It turned out that when opening water, the gas valve gradually goes through 3 stages of opening - only the pilot flame, the intermediate stage and only the main burner. At the moment of generation of the spark, the gas valve should be in the 1st stage, but due to my “edits”, it slipped through it, as a result of which a spectacular ignition of the main burner took place, which caused the “skirt” of the flame to appear at the bottom below, like a rocket.
I removed my edits and everything was fixed right away. I learned to control the gas consumption valve (described in the instructions), and it was possible that it was necessary to regulate it from the very beginning.
Now summer - gas set at a minimum, the gearbox loosened.

Advantages: Excellent appliance-1.5goda plows without problems-itself
I installed it. I had to run around, look for adapters, but the eyeliner after Proton-heaven and earth. You can adjust the minimum water pressure to fit 37-38, it is important if you have a water meter.

Disadvantages: NOT.

Advantages: quick install

Disadvantages: on the second day of use, it stopped working ((((we wash with teapots now ... constantly gives an error to A4 .... outweighed it two times .. there is traction ...Some kind of buggy model!

Comment: just one disorder
