Stop Wasting Water and Energy: Find the Best Recirculating Pump for Your Tankless Water Heater

A growing number of people are using tankless water heaters because of their compact form and high energy efficiency. The time it takes for the hot water to reach the faucet is one disadvantage, though. Recirculating pumps can help in this situation. We shall explain the top recirculating pumps for a tankless water heater in this article.

How a Recirculating Pump Works

A recirculating pump works by continuously circulating hot water from the water heater to the faucet, ensuring that hot water is always readily available. The pump is installed at the furthest point from the water heater, and it draws hot water from the heater and pumps it back to the faucet via a dedicated return line. There are two types of recirculating pumps: on-demand pumps and timer pumps.

On-demand pumps operate by sensing a drop in temperature and immediately pumping hot water to the faucet. Timer pumps, on the other hand, operate on a schedule set by the user. They turn on the pump at specific intervals throughout the day, ensuring hot water is available during peak usage times.

Factors to Consider When Choosing a Recirculating Pump

When choosing a recirculating pump for your tankless water heater, there are several factors that you need to consider. Each of these factors is essential to ensure that the recirculating pump you select meets your specific needs and requirements. Here are the key factors to consider:

  1. Flow Rate and Head Pressure: The flow rate and head pressure of the pump are crucial factors to consider. The flow rate determines how quickly water is circulated through the system, while head pressure determines the height that the pump can pump the water to. You need to choose a pump with a flow rate and head pressure that match the requirements of your tankless water heater. A pump with a low flow rate may not provide enough hot water, while a pump with insufficient head pressure may not be able to pump water high enough to reach all the fixtures in your home.
  2. Power Consumption: The power consumption of the recirculating pump is another critical factor to consider. You want to choose a pump that is energy-efficient and won’t add significantly to your energy bills. A pump with a higher power consumption may lead to higher energy costs, which can be a significant expense over time.
  3. Motor: The motor of the recirculating pump is also an essential consideration. A powerful motor can provide better performance, while a smaller motor may be more energy-efficient. It is essential to select a pump with a motor that matches the requirements of your tankless water heater and provides the necessary power and performance.
  4. Material: The material used in the construction of the recirculating pump is another critical factor to consider. You want to choose a pump made of high-quality materials that can withstand wear and tear over time. Materials such as cast iron, stainless steel, and bronze are popular choices for recirculating pump construction due to their durability and resistance to corrosion.
  5. Noise Level: The noise level of the pump is another crucial consideration. Some recirculating pumps can be quite noisy, which can be a significant concern if you plan to install the pump near living areas. Choosing a pump designed to be quiet can help to reduce noise levels and improve the overall comfort of your home.
  6. Compatibility with Tankless Water Heater: It is essential to select a recirculating pump that is compatible with your tankless water heater. Check the manufacturer’s specifications before making a purchase to ensure that the pump you choose will work correctly with your water heater.
  7. Ease of Installation: The ease of installation is another critical factor to consider. Look for a recirculating pump that comes with clear instructions and is easy to install without professional help. Choosing a pump that is easy to install can help to save time and money on installation costs.
  8. Price: Finally, consider the price of the recirculating pump. While it is essential to choose a high-quality pump, you do not want to overspend. Look for a pump that fits within your budget and meets your needs.

Step-by-Step: How to Install a Recirculating Pump for Tankless

Installing a recirculating pump for your tankless water heater is a smart move that can save you both time and money. This device can help you achieve a more consistent flow of hot water, and prevent you from wasting water and energy waiting for the hot water to arrive. Here’s a step-by-step guide on how to install a recirculating pump for your tankless water heater:

Step 1: Choose the Right Recirculating Pump

The first step is to select the right recirculating pump that fits your tankless water heater. You can choose between a dedicated recirculating pump or a retrofit pump. A dedicated pump is designed to work with your specific tankless water heater model, while a retrofit pump can work with any tankless water heater model.

Step 2: Turn Off the Power and Water Supply

Before you begin the installation process, make sure to turn off the power supply to your tankless water heater and shut off the water supply.

Step 3: Locate the Return Line

Locate the cold-water supply line that enters your tankless water heater and look for the return line. This is usually a small pipe that leads away from the water heater. If you cannot locate the return line, you may need to consult the manufacturer’s instructions or hire a professional plumber to help you.

Step 4: Install the Pump

Once you have located the return line, you can begin installing the recirculating pump. Connect the pump to the return line, making sure to follow the manufacturer’s instructions carefully. Make sure that the pump is securely attached and that all connections are tight.

Step 5: Install the Check Valve

Next, you’ll need to install a check valve on the hot water supply line. This valve will prevent hot water from flowing back into the cold-water supply line. Follow the manufacturer’s instructions to install the check valve correctly.

Step 6: Connect the Recirculating Line

Connect the recirculating line to the hot-water supply line and the recirculating pump. Make sure that all connections are tight and secure.

Step 7: Turn On the Water Supply and Power

Finally, turn on the water supply and power your tankless water heater. You may need to wait a few minutes for the pump to prime and start circulating the hot water. Check the manufacturer’s instructions for specific guidelines on how long it takes for the pump to prime.
