Choosing The Right Recirculating Pump
Understanding The Different Types Of Recirculating Pumps Available
Recirculating pumps are an essential component when it comes to ensuring hot water is readily available in your home. However, with the variety of options available, it’s important to understand the different types of recirculating pumps before making a choice.
Here are some key points to consider:
- Traditional recirculating pump: This type of pump uses a dedicated return line to continuously circulate hot water through the plumbing system, ensuring near-instantaneous hot water at each fixture. It is typically installed with a dedicated return line, which can be expensive and time-consuming.
- On-demand recirculating pump: On-demand pumps are designed to activate only when hot water is needed, eliminating the need for a dedicated return line. These pumps use a flow-activated sensor or a push-button to pump hot water quickly to the fixture. They are easier to install and more cost-effective than traditional models.
Factors To Consider When Selecting A Recirculating Pump For Your Tankless Water Heater
Choosing the right recirculating pump for your tankless water heater involves considering several factors. Here’s what you should keep in mind:
- Water heater compatibility: Ensure that the recirculating pump you select is compatible with your tankless water heater model. Different heaters may have varying flow rates and temperature settings, so it’s essential to choose a pump that can handle the specific requirements of your heater.
- Flow rate: The flow rate of a recirculating pump is a crucial factor to consider. It determines the speed at which hot water is pumped through the system. Check the flow rate of the pump and ensure it is suitable for your home’s hot water demands.
- Installation requirements: Consider the installation requirements and complexity of the recirculating pump you’re considering. Some pumps may require professional installation, while others are designed for easy diy installation. Evaluate your expertise and the time you can dedicate to the installation process.
- Noise level: Since recirculating pumps run continuously or intermittently, the noise level can be a factor to consider, especially if the pump is installed close to living areas. Look for pumps that are designed to operate quietly to ensure minimal disturbance.
- Reliability and durability: It’s essential to choose a recirculating pump from a reliable brand that offers a warranty and has a reputation for durability. Investing in a high-quality pump can significantly reduce the chances of frequent breakdowns and repairs.
Energy Efficiency Considerations For Recirculating Pumps
When it comes to energy efficiency, recirculating pumps can have an impact on both your energy consumption and utility bills. Consider the following energy efficiency considerations:
- Pump technology: Look for recirculating pumps that incorporate energy-efficient technologies such as variable speed motors. These motors adjust the pump’s speed based on demand, leading to energy savings.
- Thermal bypass valves: Some recirculating pumps feature thermal bypass valves that allow water to bypass the pump when it reaches the desired temperature. This prevents unnecessary operation of the pump, saving energy.
- Timer controls: Timer controls are another energy-saving feature found in many recirculating pumps. They allow you to set specific periods during which the pump operates, ensuring hot water is available only when needed.
- Insulation: Properly insulating hot water pipes helps reduce heat loss and eliminates the need for excessive recirculation. Consider insulating your hot water pipes to improve energy efficiency.
Choosing the right recirculating pump for your tankless water heater involves understanding the available options, considering factors like compatibility, flow rate, installation requirements, noise level, reliability, and durability. Additionally, prioritize energy-efficient features such as pump technology, thermal bypass valves, timer controls, and pipe insulation to minimize energy consumption and reduce utility bills.
With careful consideration, you can select a recirculating pump that meets your specific needs while optimizing hot water availability and energy efficiency.
Step-By-Step Installation Guide For Recirculating Pump On A Tankless Water Heater
Evaluating The Existing Plumbing System And Determining The Best Location For The Recirculating Pump:
Before installing a recirculating pump on your tankless water heater, it is important to evaluate your existing plumbing system and determine the best location for the pump. Here are some key points to consider:
- Assess the layout of your plumbing system. Identify the hot water supply line and the furthest fixtures from the water heater.
- Determine if your plumbing system has a dedicated return line or if you will need to use the cold water line as a return line.
- Choose a suitable location for the recirculating pump. It should be close to the water heater for easy installation and maintenance.
- Consider the noise level of the pump when selecting its location. You may want to install it in a utility room or other well-insulated area to minimize noise.
Shutting Off The Power And Water Supply To The Tankless Water Heater Before Installation:
Before installing the recirculating pump, it is crucial to shut off the power and water supply to the tankless water heater. Here’s what you need to do:
- Locate the circuit breaker or power switch connected to the tankless water heater and turn it off to cut off the power supply.
- Turn off the water supply valve connected to the tankless water heater to prevent any water flow during the installation process.
Connecting The Recirculating Pump To The Plumbing System And The Tankless Water Heater:
Once you have evaluated the plumbing system and shut off the power and water supply, it’s time to connect the recirculating pump to the plumbing system and the tankless water heater. Follow these steps:

- Install the pump on the selected location, ensuring that it is securely mounted.
- Connect the pump to the hot water supply line using appropriate fittings and connectors.
- Connect the pump to the cold water return line or the cold water line, depending on your system configuration.
Installing The Check Valves And Other Necessary Components:
To ensure proper functioning of the recirculating pump, you need to install check valves and other necessary components. Here’s what you should do:
- Install a check valve on the hot water supply line close to the pump. This valve prevents water from flowing back into the cold water line.
- Install another check valve on the cold water return line or the cold water line (if used as a return line), near the connection to the pump. This valve ensures water flows in the desired direction.
- Install any other necessary components according to the manufacturer’s instructions. This may include flow control valves, pressure relief valves, or additional fittings.
Testing The Recirculating Pump And Making Necessary Adjustments:
After installing all the components, it is important to test the recirculating pump and make any necessary adjustments. Here’s how:
- Turn on the power supply to the tankless water heater.
- Open any hot water faucet in the house to allow water to flow through the system.
- Activate the recirculating pump and observe the water flow. Check for any leaks or unusual noises.
- Adjust the pump settings if needed. Some pumps have adjustable timers or temperature sensors that can be modified to suit your preferences.
- Monitor the water recirculation and ensure it meets your expectations in terms of efficiency and convenience.
