From the reviews of the gas column Neva 4511:
“A good column at an affordable price, but requires some skills and knowledge. The developers successfully took all the best from the columns of German and Chinese and maximally simplified. Bought specially for the garden. We use for more than 2 years, there were no serious problems "
“I work in a gas outlet, I know a lot about water heaters. The Neva 4511 column is the cheapest, it skips only 11 liters, so if someone is washing in the bathroom, you cannot open the tap in the kitchen at this time if you do not want to burn the washable one. The main disadvantage is that it does not control the outlet temperature. Explain popular. Here the water in the heater went 20 ° C, warmed to 15 °, went out 35 ° (20 + 15 = 35). When the input level is sharply changed, for example, to 30 (30 + 15 = 45) - you feel hot. You start to mix cold water from the second tap, but this cannot be done. So the column quickly breaks down. But the manufacturer provides service centers with inexpensive spare parts. ”
Advantages of the model:
- affordable price;
- easy to use;
- compact;
- classic appearance;
- works quietly;
- display with large clear numbers;
- Auto-ignition (automatically turns on when you open the tap, turns off when the water is blocked);
- works with low gas pressure (up to 0.1 Bar)
- indication of inclusion and heating;
- the minimum water pressure (below which the column is turned off) can be adjusted;
- gas control;
- many service centers;
- inexpensive repair and spare parts.
Cons of the model:
- small throughput (11 l / min);
- sensitive to pressure and water hardness;
- not on any wall can be hung (need good insulation, dry place);
- does not control the water temperature at the outlet, only the amount of heating (how many degrees plus);
- Efficiency is lower than that of foreign counterparts;
- Periodic battery replacement is required.
- weak point - microswitch;
- not very stable quality - the device can work for many years, and can quickly break.
