The COMFORT Series focuses exclusively on domestic hot‑water recirculation. These pumps are compact, quiet, and extremely energy‑efficient, making them ideal for residential applications where homeowners want instant hot water without wasting energy.
Why COMFORT Pumps Exist
Waiting for hot water wastes time, water, and energy. COMFORT pumps solve this by keeping hot water circulating through the system so fixtures deliver hot water almost immediately. They’re designed for simplicity, low power consumption, and long service life.
COMFORT (Global + NA) — Ultra‑Low‑Power DHW Recirculation
COMFORT pumps are the smallest and most efficient circulators in the Grundfos lineup. They use only 5–7 watts and offer multiple control modes, including temperature control, timers, Temperature+, AUTOADAPT, vacation mode, and disinfection cycles. They’re ideal for small and medium homes with a dedicated return line.
ALPHA HWR — Higher‑Performance Return‑Line Recirculation
For homes that need more control or higher performance, ALPHA HWR adds ECM efficiency and advanced modes like AUTOADAPT and vacation scheduling. It’s built with potable‑approved materials and is quiet enough for residential installations.
ALPHA Comfort System — Recirculation Without a Return Line
Many homes don’t have a dedicated return line. The ALPHA Comfort System solves this by using a bypass valve under the sink to create a temporary loop through the cold line. It’s a retrofit‑friendly solution that avoids opening walls or running new piping. Temperature‑based control modes ensure efficient operation.
Where COMFORT Pumps Fit Best
Homes with long waits for hot water
Tank, tankless, solar, and heat‑pump water heaters
Single‑family homes with or without return lines
Installations where noise and energy use must be minimal
Where They Don’t Fit
Bottom Line
The COMFORT Series is designed to deliver instant hot water with minimal energy use. Whether the home has a return line or not, there’s a COMFORT or ALPHA‑based solution that fits the application.
