Review on 🔥 BOKYWOX 120W Hot Water Circulation Pump 3/4'' 110V for Solar Heater System - Stainless Steel Red by Rick Rogers

Only tested and not used for a long time but good pump so far. It works silently, which is a plus. It works great with my 20 year old Bosch instantaneous water heater in a special recirculation circuit. At first I was worried that due to its characteristics the pressure wouldn't be enough to activate the heater but it worked fine. I disconnected the pressure/flow switch that came with the kit and connected it to this circuit to control the temperature. In the end it will be an Alexa control with temperature backup. Time will tell how it holds up. Cons: Common complaints about straight threads. They are 3/4 inch but NOT NPT. The PEX's 3/4" plastic swivel adapters work great with it, as do the 1/2" NPT adapters that come with the kit.
