bayite BYT-7A014 12V DC Solar Hot Water Heater 🌞 Circulation Pump - Low Noise, 3M Discharge Head, +2.1GPM Flow Rate Review

I updated this review. Your mileage will likely vary based on usage. For me I had 3 units and after about a year one failed completely (the impeller's plastic shaft rubbed against the steel support rod and broke) and the other two became very noisy due to the same component wearing out. If you need it for occasional use to pump water with a decent stroke then this pump is for you. If you need reliable, 24/7 operation, choose something sturdier. It's a pretty good pump before it wears out…

I use this pump to circulate hot water through the radiator for my own 7 gallon RV shower. I've used it three ways: above the water tank and filled with a large pump, at the bottom of the water tank where it fills itself, and completely submerged in the water tank. Only works reliably when fully submerged. Still, in this configuration it's a solid little pump for the money (and they're cheap enough that you can keep a spare on hand). It pumps about 1.5 gallons per minute through a radiator (in…

My first one failed eventually, I think it lasted 2 years, installed with a highletgo thermostatic relay module, 20-30' wires soldered between probe and module, glued to Hot water distributor under my pier and beam home. In winter he turns on this pump several times an hour, in summer less often. There have been a couple of instances where I've removed and drained my tubes but forgot to fill the recirculation line and blow air through it, so I know it ran dry a few times and got very hot, but…

Update from 07/31/20: finally replaced the third by the fourth of the same one. Update 06/22/20: The impeller shaft of the third pump is now constantly vibrating in the bearing, although it is pumping normally. Update 10/19/19: I still use the third pump almost daily. I rebuilt my heat exchanger from 1/4" copper to 3/8" copper and the pump noise is completely gone now. The whole system is now 3/8 inch which is recommended. I suggest you follow this rule and also don't pulse through the impeller
