I’m thinking of buying the same one, but the old one says VILO, and on the Internet it’s WILO, but I saw WILLO on the market, and they say it’s some kind of analogue. So where can I look for at least the same quality as I had? And where is the guarantee that this one will work for at least 6 years? Mess? Worked for 6 years. It worked for 6 years and started making noise. I wonder how long it will last?

The pump is reliable and quite well assembled. Installed a year ago, no problems yet. The house is small, two-story, and in addition to installing the pump, a lot of work was also carried out during the same period, so the craftsmen did everything, and quickly, and installed it right away. It has three speeds that can be adjusted, depending, for example, on the outside temperature; in winter it gets quite cold here. The operating range of this pump is from -10 to +110. It hasn't broken down yet, no problems have arisen. We were afraid that it would work noisily, but its operation is not felt at all, sometimes something like gurgling and that’s all. There were no particular problems. I really can’t say anything about special gas savings; if it saves, it’s not a very large amount, so we didn’t particularly notice. use Wilo Star-RS 25/4 month or more i recommend it should buy |
He worked honestly for 10 years and began to rattle! I think he justified his cost for all the years! Reliability Price |
