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 pump operated for 12 years in a rural house with a heated area of 100 sq m and was replaced with a new one of the same model when the heating boiler was replaced. The used pump, in absolutely working condition, was removed, underwent thorough maintenance, and was stored as a spare. Its low power consumption allows it to be used with a computer uninterruptible power supply, and the battery lasts for 3 hours of operation, which is very valuable in rural areas with frequent power outages. Throughout its use, the pump operated at minimal capacity. A wonderful device! Reliability, stable performance, low power consumption, inexpensive (at the time of purchase, the price was less than 2000 rubles).

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. |
