A tankless water heater recirculation pump works by keeping hot water flowing through the system. It pumps unused hot water back to the heater, ensuring immediate availability of hot water when needed.
Hot water is a necessity in every household, yet waiting for it to heat up can be frustrating. A recirculation pump solves this problem by instantly providing hot water. It’s an energy-efficient solution to minimize water wastage and reduce utility bills.
This pump is installed in-line with the tankless water heater and the furthest plumbing fixture in the home. When the fixture is turned off, the pump circulates the unused hot water back to the water heater, so the next person who turns on the hot water will not have to wait. In this article, we will dive deeper into the process of how a tankless water heater recirculation pump operates.

Understanding Tankless Water Heater Recirculation Pump
Tankless water heaters are regarded as one of the most efficient ways to provide hot water supply to homes. However, when using tankless water heaters, users often face the issue of waiting for hot water to reach their faucets or showerheads.
To avoid this problem, installing a recirculation pump is essential. In this section, we will explore how a tankless water heater recirculation pump works.
Explanation Of How Tankless Water Heaters Work
Tankless water heaters are compact and wall-mounted units that only heat water when needed. Unlike traditional tank water heaters that store hot water, tankless units utilize an internal heat exchanger to heat cold water on-demand. When hot water demand arises, the tankless unit’s sensors detect water flow and triggers the internal heat exchanger to heat the water.
Once the hot water tap is closed, the tankless unit automatically shuts off, resulting in significant energy savings.
Overview Of How Recirculation Pumps Work
A recirculation pump makes hot water available instantly by circulating hot water through the pipes. It works by continuously circulating hot water through the pipes and back to the water heater. The pump is wired to the tankless unit and has a sensor that triggers the pump each time hot water is demanded.
When hot water is demanded, the pump circulates hot water through the pipes, minimizing the amount of cold water that has to be drawn out of the pipes. This results in hot water instantly available at the tap, without waiting for the cold water to be flushed out of the pipes.
Importance Of Installing A Recirculation Pump With A Tankless Water Heater
The benefits of installing a recirculation pump go beyond instant availability of hot water. Here are some reasons why you should install a recirculation pump with a tankless water heater:
- Saves water: A recirculation pump reduces water waste by minimizing the amount of cold water wasted while waiting for hot water to arrive.
- Energy efficient: A recirculation pump reduces energy consumption by minimizing the amount of hot water used to flush out the cold water.
- Cost-effective: A recirculation pump can save homeowners up to $100 annually in water and energy bills.
- Comfort and convenience: Installing a recirculation pump eliminates the wait for hot water, ensuring comfort and convenience for home users.
- Eco-friendly: By reducing water and energy use, a recirculation pump also has a lower carbon footprint, helping to preserve the environment.
A tankless water heater recirculation pump is an essential component in providing instant hot water supply to homes. By understanding how it works and its benefits, homeowners can save water, energy, and money while ensuring comfort and convenience.
How Tankless Water Heater Recirculation Pump Works
Tankless water heaters are a popular choice among homeowners for their energy efficiency and space-saving features. However, these systems often require a recirculation pump to ensure hot water is readily available at all times. In this post, we’ll dive into how a tankless water heater recirculation pump works and what components are involved in the process.
Explanation Of The Recirculation Process
The recirculation process is designed to keep hot water flowing through the pipes and eliminate the need for users to wait for the water to heat up. The tankless water heater recirculation pump works by constantly circulating hot water through the pipes, ensuring that the water in the tankless unit is always hot and ready to use.
Detailed Breakdown Of The Components Involved In The Recirculation Process
Several components are involved in the recirculation process, including:
- Recirculation pump: This is the primary component of the system. It pushes hot water from the tankless unit through the pipes to ensure that there’s always hot water available.
- Check valve: The check valve prevents the flow of hot water from the pump back into the tankless unit. This ensures that the hot water is always flowing in the right direction.
- Sensor valve: The sensor valve detects when hot water is flowing through the pipe and automatically shuts off when it senses cold water. This prevents the hot water from being wasted.
- Aquastat: The aquastat is a sensor that detects the temperature of the water in the tankless unit. It sends a signal to the pump to start circulating hot water when the temperature falls below a certain level.
Steps Involved In Setting Up A Tankless Water Heater Recirculation Pump
The steps involved in setting up a tankless water heater recirculation pump are as follows:
- Choose the right recirculation pump for your needs. Make sure to check the pump’s flow rate, head pressure, and power requirements before making a purchase.
- Install the check valve and sensor valve in the recirculation line. Place the check valve before the pump and the sensor valve after it.
- Install the aquastat on the tankless unit and connect it to the recirculation pump.
- Set the temperature on the aquastat to the desired level.
- Turn on the pump and test the system to ensure everything is working correctly.
A tankless water heater recirculation pump is an essential component that ensures hot water is readily available at all times. By understanding the recirculation process and the components involved, you can install and maintain the system correctly, guaranteeing hot water on demand.
Conclusion
A tankless water heater recirculation pump is a device that helps to provide hot water on demand without waiting for long before it gets to your faucet. It recirculates water through a loop from the fixture back to the heater to keep it warm and ready for use at any time.
The pump ensures that you have hot water without wasting time or energy. This technology is a great investment for homeowners who value convenience and want to reduce water wastage. With a tankless water heater recirculation pump, you can enjoy a more comfortable living experience while saving on energy bills.
Remember to hire a professional plumber to install your pump in the right location, and ensure that you maintain it regularly to keep it working correctly. Thank you for reading and we hope you found this information helpful in guiding your purchase decision.
