It was necessary to buy and install a high-quality gas double-circuit boiler in a small, but two-story, private house. Chose Viessmann because German design. True, it is not entirely clear where it is collected. The boiler was decided to take an ordinary, rather than fashionable condensing one. I think that the simpler, the more reliable. There were also size requirements and in the end I took this model. Small size and light weight. You can hang it anywhere and on anything. We connected ourselves, the process is simple and clear. Gas workers were needed only to seal the gas meter. The developers adapted the design to the specifics of our gas networks. The boiler can operate at a significantly reduced gas pressure from the nominal value. Controlled (as the developer says, modulated) gas burner made of high quality stainless steel. Such a controlled burner does not allow excessive consumption of gas and flexibly regulates the heat output of the boiler. Two heat exchangers - copper and stainless steel, respectively, for heating and hot water supply. Good capacity of the heat exchanger-water heater. Holds temperature even at a decent pressure. Well thought out boiler control unit. Very, very quiet. The neighbor has some kind of cool Italian boiler, so when it is ignited it slams on the whole house, and then just a quiet click. Sensitive to water hardness. Developers do not recommend working on hard water. You can work more precisely, but you must definitely install a flow block with a replaceable filter cartridge. |
No advantages complete nonsense, German rip-off, I don't recommend anyone to buy Viessmann...  Roman: use Viessmann Vitopend 100-WH1D258 23 kW more than year i recommend it don't buy |
High performance. Compared to ATONs, it consumes less gas. I can compare, the neighbors in the entrance have two of these. And the Viessmann Vitopend is much smaller in size. Works quietly. The start, of course, is audible. But, unlike the same ATONs, it starts without cotton. But then the pump is almost inaudible. Provides hot water quickly. Well, not instantly, of course, but when compared with the old Soviet column, it’s very, very fast))) The hot water pressure is also very decent. Adapted to our not very stable gas networks. Convenient and detailed control. You can quite accurately regulate the temperature of the batteries and heat the hot water to your liking. On the LCD screen, all the most important parameters of the boiler are immediately visible. A ten-year warranty is incredibly cool in today's times! But I hope I don't need it. German quality. I love German cars and home appliances. We have to learn and learn from them. The price for a European boiler is simply excellent and the price / quality ratio is very attractive. Sometimes the boiler lives its own life. Turns on and immediately turns off the burner, then after a pause it starts fully. But since it works quietly, it cannot be said that it is very disturbing. I had to buy an electric stabilizer. Otherwise, in the evenings, due to voltage dips in the power grid, the boiler stupidly turned off. use Viessmann Vitopend 100-WH1D258 23 kW month or more |
