Booster & Recirculation Pumps
Whole-house pressure boosters, hot water recirculation pumps and hydronic circulators, compared on horsepower, flow, pressure and voltage.
A booster pump raises low household water pressure, usually installed after the meter or pressure tank; constant-pressure models vary their speed to hold a set pressure. Recirculation pumps keep hot water near the taps so it arrives in seconds, often with a timer or a sensor valve under the farthest sink.
Circulators are the small pumps that move water through boilers and radiant heating loops. They look similar to recirculation pumps but are sized for heating systems.

Waiting for hot water
Recirculation pumps keep hot water close to the farthest tap.
Hot-water heating
Hydronic circulators move water around boiler heating loops.
Before you buy
- Code. Boosting a city supply can require a backflow device; check local code.
