Consider the above factors and your budget to help you determine the best recirculating pump for your home. We recommend consulting a professional to make an informed decision. A consultation can also address any concerns you may have about installation, maintenance, and potential energy savings.

Technological advancements have made recirculating pumps smarter and more efficient in recent years. Modern systems can learn your household’s hot water usage patterns and adjust operations accordingly. Some of these systems integrate with home automation platforms, allowing homeowners to control and monitor their recirculating pumps via smartphone apps.

The recirculating pumps themselves can be included in several different systems that work for different home layouts and hot water needs.

While a hot water recirculating pump does consume some electricity, modern efficient models used properly (with a timer, for example) can minimize energy consumption. The energy savings from reduced water heating needs can often offset the pump’s electricity usage.

Some systems can use existing cold water lines as the recirculation line, simplifying installation. These solutions often involve a pump at the water heater and a valve at the farthest fixture to move heated water as needed. This method reduces the need for extensive plumbing modifications, but cold water still recirculates back to the heater instead of being wasted down the drain.

Full recirculation systems require a dedicated return line from the farthest fixture back to the water heater. While these systems are effective, they can be challenging to install in existing homes due to the need for additional plumbing. However, they eliminate cold water in the lines, providing the easiest, most efficient path for getting hot water from your fixtures.

Hot water recirculating systems provide instant hot water at your faucets, eliminating the need to clear the pipes with cold water. This is particularly helpful in larger homes or buildings where the water heater is far from the point of use.

Are you tired of waiting for hot water to reach your faucets? A hot water recirculating pump might be the solution you’re looking for. This device can save time, water, and energy by making hot water readily available at your taps. We recommend professional installation for this project, but it’s helpful for homeowners to understand how these systems function.

Proper maintenance extends your hot water recirculating pump’s lifespan and keeps it operating efficiently. Here are some maintenance tips to keep your system in top condition.

Installing a hot water recirculating pump requires careful planning and execution. Here are some key factors to consider:

Point-of-use pumps are installed at specific fixtures, as Trethewey shows with the system in the bathroom vanity. These are easier to retrofit in existing homes but may not be as efficient as full systems. They’re convenient for homeowners who want instant hot water at particular locations.

We recommend having a licensed plumber install a hot water recirculating pump for you. As Trethewey says, “A recirc[ulating] line improperly controlled could be one of the biggest energy wasters in the whole building.” Do-it-yourself (DIY) installers could end up accidentally wasting hot water and overworking the water heater. A professional also knows how to comply with local building codes.

In the video above, This Old House plumbing and heating expert Richard Trethewey explains how a recirculating pump works and its benefits. Below, we’ll recap these details and answer some common questions about hot water recirculating pumps.

Integration with home automation systems allows homeowners to set schedules, monitor energy consumption, and receive maintenance alerts. These features make it easier to manage the system efficiently and ensure continuous optimal performance.

With a properly functioning recirculating pump, you should have hot water almost instantly when you turn on the tap. The exact time may vary slightly depending on your home’s plumbing layout and the distance from the water heater, but it should be significantly faster than without a pump.

Installing a hot water recirculating pump benefits the environment by reducing water waste and optimizing your energy use. However, it’s crucial to use timers and aquastats effectively to ensure you’re saving rather than expending extra energy. Also, consider the energy source for your water heater. Homes using renewable energy sources will find even more environmental benefits.

No, a hot water recirculating pump should not run continuously. Using a timer or smart controls to operate the pump only during peak usage times can significantly reduce energy consumption while still providing the convenience of instant hot water when needed.
