Grundfos 98420224 Comfort PM AutoAdapt Hot Water Recirculation Pump – 1-1/4 Inch NPSM, 115V With ECM Motor & Check Valve

About This Product

If you're tired of waiting forever for hot water to reach your tap, this Grundfos Comfort PM recirculation pump is a total game changer.

It's designed for residential homes and uses a super quiet permanent magnet motor that sips power—as little as 5 to 8.
5 watts.
The real star is the AutoAdapt mode, which learns your household's hot water usage patterns and only runs the pump when it's actually needed.

That means you get fast hot water without wasting energy or water, and it's way more efficient than old-school pumps that run constantly.

Besides AutoAdapt, you can also set it to run at 100% or by temperature, depending on your preference.

It handles a max head of 3.
9 feet and comes with a built-in check valve to prevent backflow.

The 1-1/4 inch NPSM union makes it easy to hook up, and it runs on standard 115V with a 6-foot line cord.

The ECM motor is reliable and whisper-quiet, so you won't even notice it's there except for the instant hot water.
Perfect for upgrading an older system or building new—it's the kind of smart home tech that actually pays for itself over time.
