For homes that want a water heater that will last longer than conventional water heaters, be significantly more energy-efficient, require less maintenance, and save space in the process, tankless water heaters are fantastic, especially when big volumes of hot water aren’t always essential. The time it takes for the hot water to warm up before it can be dispensed is a common issue with tankless water heaters, even though they don’t have many drawbacks.
Money drains down the drain in the form of cold water while you wait for it to warm up. Fortunately, there is a solution to install a recirculation pump! It’s simple to locate a team of specialists with decades of plumbing experience who can explain how the recirculation pump can help your home’s water heater and hot water supply. We’ll also review additional factors before installing a recirculation pump.
Recirculation Pump: What Is It?
The major objective of a hot water recirculation pump is to guarantee that hot water is always accessible from your home, wherever and whenever you need it. It keeps all the advantages of having a tankless water heater while giving your house instant hot water that conventional water heaters are known for.
Is a recirculating pump necessary for a tankless water heater?
Yes, it is the answer. But it must be done correctly, or it could waste a lot of water, use up more energy, and make your hot water less convenient than it would be. The many alternatives for using a recirculating pump with a tankless water heater to conserve energy and water are described below.
Recirculation pumps: Are they included with tankless water heaters?
Recirculation pumps are optional on certain tankless water heater types but are standard on others. This is done primarily to keep tankless water heater prices down for consumers. While they can be purchased without one, it is always advised to start by getting a tankless water heater with one. Instead of buying a brand-new water heater, consider your choices for having a pump retroactively added to an existing tankless water heater that is already installed in your home.
Full Recirculation Pump System vs. Recirculation Pump Comfort System
Recirculation pipes can be installed in one of two ways:
Full Recirculation Pump System
If you choose this option, you’ll need to connect more piping to your system to create a “hot water loop,” ensuring that the water is circulated and kept warm until you turn on the faucet again. This may work best for new building projects due to the quantity of piping that needs to be put in!
Comfort Recirculation Pump System
The comfort system makes it simple to install this affordable solution within your pump without needing additional piping. It takes advantage of your system’s current cold-water line and offers your water heater the capacity to return water, keeping it from getting cold and being squandered the next time you use it.
It ultimately expedites the entire procedure. In conclusion, recirculation pumps are essential. Most homes have one-way plumbing; however, by adding a recirculation pump, you can gain various advantages.

This would be a choice if someone wanted to purchase a conventional tankless unit and add recirculation later rather than purchasing the more expensive unit. Unfortunately, this installation is more expensive, and the system does not function as effectively. We have utilized this technique to reduce water waste from waiting for hot water to reach fixtures if an older tank is installed. It’s unnecessary to replace a tankless just a few years old to reduce wait times and conserve water!
You’ll have to wait much longer for the hot water to come out of the kitchen sink or shower if they are located far from the water heater. We think it’s a win-win when you install a recirculation pump since you’ll notice that the hot water heats up and gets to you more quickly.
Avoid Wasting Water
Tankless water heaters have developed into a fantastic option for homeowners trying to lower their energy usage over time. By reducing the roughly 30 gallons of water wasted each day while waiting for hot water to reach your faucet, a water heater recirculation pump can also help your household avoid water waste.

Even if you hire a plumber to install your pump, the lower water, energy, and water bills will allow you to recoup your investment quickly. The ordinary homeowner can recover their initial investment in just a few years thanks to their annual savings of $50 to $100!

Use of farthest sink
The farthest sink from the water heater can use a crossover tee with some of the newest tankless water heater models we are installing. As the internal pump in the water heater pulls the hot water closer to the farthest fixture, this tee will allow some of the cooled-off water in the hot water line to enter the cold-water line.
The crossover tee stops letting water through when the water at the fixture heats up, keeping the cold-water line from heating up and turning off your tankless water heater. If you desire the convenience of a recirculating line but cannot install an insulated recirculating loop due to expense or because the pipes are inaccessible to run a line back to the water heater, this is a viable solution.
