Excuse me, how noisy is the domestic heating circulating pump? Let's talk about what everyone has used! Give points as appropriate! !

I don't think it's noisy The noise of the heating circulating pump in my house is not as big as that of the computer and refrigerator. It's not obvious unless you listen carefully.

But my circulating pump is connected to the stove in the yard. And there are horizontal and vertical heating circulation pumps, which have high noise and low noise! My house is horizontal, only two or three hundred dollars. I used it for a year last year, and I still use it this year. A good circulating pump costs 1000 yuan.
