Ariston Fast Evo 11B
This automatic device, the heater is able to turn on and off independently. The productivity is about 14 liters per minute, making it one of the optimal for centralized water supply systems, which produces about 9-11 liters per minute. The temperature is adjusted only once - in the future the water heater will maintain it independently.
Operating the device is very simple - there is only one handle on the body, which is responsible for adjusting the temperature. This heater does not have a display, so you need to adjust the water according to your feelings. To the left of the rotary handle there is a special indicator light. If it lights up, it means that there is a need to replace the batteries located in the piezoelectric element. When it flashes one to five times in a row, you need to call a technician. The heater has a bottom water supply, which makes connecting the device easier. Near the water inlet, the device has another knob that adjusts the volume of water entering the heater. In essence, this is a standard faucet regulator.
Advantages:
- Attractive appearance;
- High build quality;
- Ease of use.
Flaws:
- The copper radiator is quite thin - some models leak quickly;
- The batteries in the piezo ignition discharge quite quickly;
- It becomes clogged with scale if the water is hard.
