We have two pumps in operation, they have worked for 16 seasons, but they are genuine, there were no Chinese ones back then. After the 15th season, one seized up a bit :-)

About five years ago, I bought another one, but it turned out to be Chinese, still working for now :-)

Very easy to install, no gaskets or gaskets needed. At the same time, the build quality is high, nothing backlashes and does not depart. In a word, brand quality. It works absolutely silently, even if you stand nearby, you can not hear anything. Vibrates, it is, but also not critical. At the same time, the pipes do not tremble, as it was with the old one. Three speeds of work. To be honest, I have never switched to the maximum, the first two are enough to ensure good pressure in the system. Suddenly, consumes a little electricity. Compact and looks like modern technology.

The pump was installed a few months ago. I can immediately say that the main goal - saving at least partial gas - is being achieved, I won’t say that we saved a lot, but still some amount, albeit a small one. They delivered it to us quickly, there were no problems. I immediately felt that the rooms, which were previously poorly heated, now became much better. It works almost silently, sometimes there is a small sound, like normal from a battery, but it doesn’t interfere. The pump itself is small, can be installed almost anywhere, it does not interfere. So I see virtually no downsides, it works fine, and consumes almost no electricity. In the cold season, we realized that we could turn the gas on almost to minimum and the house would still warm up normally.
