Navien Tankless Water Heater With Recirculation Pump

Hot Water When You Need It Without the Wait 

Say goodbye to waiting at the tap. Navien tankless water heaters with built-in recirculation deliver hot water faster, more efficiently, and without waste. Designed for Canadian homes and Ontario winters, these ENERGY STAR® certified systems combine continuous flow heating with an internal pump that keeps hot water close to your fixtures so it’s ready when you are. 

  

If you're wondering “Is there a tankless water heater that gives hot water instantly?” — this is your answer. 

How Navien’s Recirculation Technology Works?

Traditional tankless systems wait until you open the tap to start heating water which means a delay and wasted cold water. Navien solves this with ComfortFlow® technology, which uses an internal pump and buffer tank to circulate pre-heated water through your plumbing loop. 

  

This means: 

  

  • Faster hot water delivery to fixtures 
  • Reduced water waste 
  • No need for external recirculation hardware 
  • Lower standby energy use with smart scheduling or motion-based control 

  

Whether your home has a dedicated return line or needs a crossover valve, Navien has flexible options for setup.

Why Choose Navien with Built-In Recirculation? 

These units are a perfect fit for: 

  • Homes with multiple bathrooms or long pipe runs 
  • Busy families tired of waiting for hot showers 
  • Ontario homeowners looking to reduce utility bills 
  • New builds or tank-to-tankless upgrades 

Plus, Navien’s compact, wall-mounted design saves space, while its ultra-low NOx emissions make it a greener choice. 

Maintenance Tips For Long-Lasting Performance 

To keep your Navien system running at its best, we recommend: 

  

  • Descaling annually, especially in hard water zones 
  • Cleaning filters every 6–12 months 
  • Checking recirculation schedules to optimize efficiency 
  • Annual inspections to maintain warranty coverage
