Werkt heel goed.

Bought this and installed it. Works great!!! I have home assistant controlling the pumps on/off time. I now have instant hot water at all my top-floor taps, no more waiting for the hot water. I should have bought this years ago

Sieht hochwertig aus, gefällt mir.

Runs well , you need a a much better instruction booklet with clearer photos and larger print . .. be great if WiFi included in USA import circulators . A YouTube video would be helpful!

Great feature.

Semble de très Bonne qualité. Pas encore montée, donc je ne peux pas confirmer toutes mes très bonnes premières impressions.

Everything is perfect with this device however, in order to sweat it into a water system with three-quarter inch pipe, you need to buy extra adapters for the three-quarter G fittings on the volute discharge and inlet. Very inconvenient for users in USA. A three-quarter inch PT thread would’ve been more convenient and required less space to install.

Does the job- not quite the output of the $700 German pump it replaced but was an easy swap to get the system up and running at a tenth of the price.

Bought two of these to stop running water until it gets hot. I have not installed it yet but I tested them in air when they arrived and they run too quiet to hear. It'll take some time to set one up as it will be the return for the longest hot water line, back to the drain valve at the base of the hot water heater. 120 feet from "hot" out to "cool" return. Also plan on a programmable temperature controller to start pumping when the water is slightly warm and shut off the pump once the return temperature becomes hot...to save the pump from really hot water. That controller is about $20 on Aliexpress. Good luck with your project. Only 4 stars because I haven't installed and tested it yet.

Works well but is noisy if mounted directly to rigid galvanized pipe. I wish that one end of the pump had a 3/4" female union connection instead of male at both sides. I ended up installing it on the hot water tank outlet with a flexible connector from the pump to the house piping. Use a dielectric connector or lots of teflon tape on the pump nipples as stainless steel could pit in contact with copper fittings. Very good value all the same.
