Not sure what you mean. You kind of need a pump to move water through your system for baseboard/heated floors. Pump turns on when there is a call for heat, or pump plus zone valve depending on if there are multiple zone or multiple pumps. Not sure how you can cap it off unless you have a tankless with a built in pump.

Hot water for all your other stuff just comes from water pressure.

He's talking about a recirculation pump for the hot water heater. You can use this same type of pump to keep the water in your hot water lines hot all the time, like Pat said.

My brain broke when he said they aren't pumps. And I'm a fake engineer not even a real one.

Sure. They can't self prime and are 1/32 HP.
Probably produce 6" of head.
The 15psi on the gauge is the weight of the column of water in a two story building.

I guess it is a class of pumps...

Yeah, hot water dedicated loop for faucets, showers and such. It was originally the model home for our development so it has quirky things like this and 12" on floor joists. Guess half of the loop has 20yo water...Screenshot_20251118-225706.pngPXL_20251119_034240115.MP.jpg
