Model overview based on user reviews  
The Zanussi Smalto water heater is praised for its compact design and efficient heating capabilities. Users appreciate its space-saving layout, which appears less bulky compared to traditional cylindrical models. It features two power settings, 1200 and 2000 watts, allowing for faster heating when needed, reducing waiting time by about 40%. An important safety feature is the built-in RCD, which protects against current leaks. The product comes with a two-year official warranty. However, some users note a slight noise when both heating elements are in use, similar to an electric kettle. Overall, the Zanussi Smalto is considered a reliable choice, especially for those experiencing frequent hot water supply interruptions.
Pros

Cons

Electric boiler with a convenient design and fast heating
28 June 2017 
Since our city's municipal services traditionally leave residents without hot water supply during the summer, I can't imagine life without a water heater anymore. Electricity prices are indeed biting now, but if you compare them with the price of hot water, the figures are comparable, if not cheaper. Our old Ariston electric storage boiler lasted 13 years, but it was time for a replacement, and there was a serious reason for that. During the last service and cleaning, the plumber said the tank inside was actively rusting and showed the rust in the sludge that was cleaned out of the electric boiler. According to him, once the process starts, it can't be stopped, and the water heater doesn't have much time left. So I decided to pull a "trick up my sleeve." I sold the old one for cheap, and instead bought a new one of the same model.
I really liked its layout. Compared to the old cylindrical one, it takes up much less space; to be precise, it looks less bulky and doesn't loom over. Another important and pleasant feature is its power. The old water heater had a heating element of only 1200 watts and it took a long time to heat up. This one, however, has two power settings: 1200 and 2000 watts. So, if all the hot water is used up and I need to quickly heat new water, I just switch the heating to the second setting, and the waiting time is reduced by about 40%. Another important feature, which we didn't have before, is the built-in RCD (Residual Current Device). It protects against current leaks that can occur in heating elements and will shut off the water heater if they become dangerous for people. Two-year official warranty.
When using both heating elements, there is a slight noise resembling the sound of an electric kettle heating up. This sound can only be heard in the bathroom or in the kitchen if the bathroom door is slightly open.

Many customers know the Zanussi brand for relatively inexpensive, but high-quality kitchen appliances. Water heaters that are included in the company's range can be given a similar characteristic. The Symphony series includes the most affordable models, while the Smalto series is more advanced. Smalto ZWH/S 80 with a flat body is suitable for those who do not like cylindrical boilers due to their design or are not suitable due to their great depth.

Half power mode

The Zanussi Smalto is equipped with two heating elements and can operate at half power (1.2 kW) or full power (2 kW). The first mode allows, if necessary, to save electricity or use various heating elements to extend their service life.

The temperature is regulated within 30-75°C. According to the manufacturer, the water in the tank heats up in 2.5 hours.

8 year warranty

The “minus” of storage water heaters is the possible leakage of water due to corrosion in the walls of the tank. Zanussi did not approach this issue in a stereotyped way. When water is heated, the enamel of a special composition on the walls of the tank "expands" in proportion to the metal. As a result, the risk of cracking and corrosion is significantly reduced. According to the company, the service life of such enamel is up to 10 years. At the same time, the warranty for the tank is 8 years. The standard safety features are not forgotten either: the device is equipped with a protective shutdown device, an overheating system and overpressure protection, which will surely please buyers.

The disadvantage of the model — the lack of a water temperature indicator — can be forgiven given its price. By sensors, you can only find out that the device is turned on and heats the water. If you want a similar model but with a "thermometer", check out the ZWH/S 80 Smalto DL (it costs $20 more).
