A solid pump that is suitable for inclusion in any home heating system. There are no special problems, it lasts a long time. Built with integrity, the body does not leak, parts do not wobble, and the threading does not leak. It's immediately clear that this is true German build quality. It does not remind you of its presence at all. It operates extremely quietly, only occasionally bubbling when air gets into the pipes. This is probably the main advantage of the model because I had a hard time with noise from the last pump. It's convenient to adjust the operating speed, though even at the minimum, it works quite efficiently. It is relatively inexpensive for a branded German pump. I tend to be cautious with inexpensive equipment, but this one has never let me down. It looks good and doesn't need to be hidden behind a curtain or wallpaper. It's immediately apparent that this is a modern and expensive unit, not a cheap mass-produced item with peeling paint on the body. Switching rheostats on power control can act up. This appears after many years of work and, in principle, is not critical. If you wish, you can either disassemble and repair it yourself, or call the master. |
Solid German circulation pump, which is worth the money that they ask for it. Works silently, long and reliably. It operates completely silently, you set it up and forget about it. I remembered about the pump for the first time only when, due to a minor battery malfunction, the house cooled down for the first time. Before that, there was no noise from it at all. You can adjust the speed of operation depending on the temperature in the apartment. It adjusts smoothly and conveniently, I rarely switch it to maximum power, the first two speeds are usually enough. It does not fail due to voltage fluctuations. Even if the voltage in the network fluctuates to the point where the computer shuts down and the lights noticeably flicker, the pump continues to work. Good price-quality ratio. There is no hotel switch, that is, the pump shutdown system will have to be organized independently, for example, from a socket. Graphite bearings sometimes break. use Wilo Star-RS 25/2 month or more |
The old circulating pump broke down, which lasted about six or seven years. So, I had to urgently replace it. I decided to buy this particular model because I trust the manufacturer (the previous one was also Wilo brand) and it has suitable specifications. This pump is not cheap; there are a lot of cheap Chinese options on the market now, but I decided not to tempt fate and chose the German-made one instead. For now, I can say that at first glance the model is of high quality. The price, of course, is not the most attractive, but it is compensated by German quality. I think it's better to buy this pump once than to buy cheap Chinese counterparts before every heating season. The pump is compact, installation is simple thanks to the screw system. As for the work itself, there are no complaints - he copes with the tasks set without question. The manufacturer has provided three modes of operation: the difference lies only in the speed of water circulation in the heating system. In practice, it is enough to set the appropriate mode and never return to this issue. I want to note that at any speed the pump works almost completely silently. With a sufficiently powerful engine, it does not consume a lot of electricity, which is very good. The pump works great, no issues. |
