Gorenje GBF 100 E/V9

First of all, it must be said that this is a convenient and reliable water heater, designed for long-term use over many years. The manufacturer provides a two-year warranty for any malfunctions and additionally guarantees 10 years of trouble-free operation of the tank. This is one of the longest warranties, and the company offers it for good reason. I'll start by noting that with a capacity of 50 liters, this boiler weighs 24 kg. The reason is simple - the inner tank, designed for high network pressure (up to 9 atm), is made of genuinely thick sheet metal. For comparison, I’ll say that cheap water heaters of the same capacity usually weigh no more than 18 kg. But its protection against leaks is not only due to the thickness. Protective enamel with primer and an increased magnesium anode reliably protect the metal from corrosion. Two so-called "dry" heating elements have a comparatively low power of 1400 W (2 x 700 W) and are controlled by a mechanical regulator. This scheme reduces scale build-up and allows for quick replacement of the heating element if it fails. Moreover, the heating elements are connected in parallel, so a failure of one of them will not affect the performance of the other, and the water heater will continue to work.
