Are You Wasting Energy? Uncover The Truth About Tankless Water Heaters And Recirculation Pumps

Tankless water heaters have gained popularity due to their energy efficiency and compact size. However, many homeowners wonder whether tankless water heaters come with recirculation pumps. This blog post explores the relationship between tankless water heaters and recirculation pumps, providing a comprehensive understanding of their functionality and applicability.

What is a Recirculation Pump?

A recirculation pump is a device that continuously circulates hot water through the plumbing system, ensuring instant access to hot water at all fixtures. This eliminates the need to wait for cold water to run out before hot water reaches the tap.

Does Tankless Water Heater Have Recirculation Pump?

Typically, tankless water heaters do not come with built-in recirculation pumps. However, it is possible to install a separate recirculation pump in conjunction with a tankless water heater. This can provide the benefits of instant hot water without the need for a large storage tank.

Benefits of Installing a Recirculation Pump with Tankless Water Heater

• Instant Hot Water: Eliminate the wait for hot water at any fixture.
• Energy Savings: Reduce energy consumption by eliminating the need to reheat standing water in pipes.
• Comfort and Convenience: Enjoy the luxury of having hot water on demand.
• Reduced Water Waste: Minimize water usage by preventing the flow of cold water while waiting for hot water.

Considerations for Installing a Recirculation Pump

• Cost: Installing a recirculation pump requires additional equipment and labor costs.
• Energy Consumption: The pump will consume electricity to circulate water, which can add to energy bills.
• Optimal System Design: The pump should be properly sized and installed to ensure efficient circulation.
• Maintenance: Recirculation pumps require regular maintenance to ensure proper operation.

How to Install a Recirculation Pump with Tankless Water Heater

Installing a recirculation pump with a tankless water heater requires the following steps:

• Determine the pump location: Choose a central point in the plumbing system.
• Install the pump: Connect the pump to the plumbing system and power supply.
• Connect to tankless water heater: Install a tee fitting to connect the pump to the hot water outlet of the tankless water heater.
• Set the timer: Program the pump to circulate water during peak usage times.

Alternatives to Recirculation Pumps

If installing a recirculation pump is not feasible, there are alternative methods to reduce wait times for hot water:

• Insulate Pipes: Insulating hot water pipes can minimize heat loss and reduce the time it takes for water to reach fixtures.
• Install Point-of-Use Water Heaters: These small, under-the-sink heaters provide instant hot water at specific fixtures.
• Use a Demand Water Heater: A demand water heater heats water only when needed, eliminating the need for a storage tank.

Recommendations

While tankless water heaters do not typically have built-in recirculation pumps, it is possible to install a separate pump to provide instant hot water. However, it is important to consider the costs, energy consumption, and maintenance requirements before making a decision. By understanding the benefits and considerations of recirculation pumps, homeowners can make an informed choice to enhance the efficiency and convenience of their tankless water heating system.
