Powerful, On-Demand Hot Water - Built for Ontario Homes 

Looking to replace your old water heater with something more efficient and reliable? Rinnai tankless water heaters are a top choice for Ontario homeowners who want instant hot water, compact design, and long-term energy savings. With advanced heating technology and built-in cold-weather protection, these systems deliver the performance you need without the wait. 

  

If you’re asking, “Is a Rinnai tankless water heater worth it?” or “Can I replace my 50-gallon water tank with a tankless?” — this is the upgrade you've been looking for. 

How Rinnai Tankless Systems Work ?

Rinnai’s tankless technology heats water only when you need it. Cold water flows through a high-efficiency gas burner that instantly brings it up to temperature — no storage tank required. The system adjusts output automatically based on usage, so whether you're showering, running laundry, or washing dishes, you’ll always have a steady supply of hot water. 

  

This on-demand design helps: 

  

  • Save energy by eliminating standby heat loss 
  • Deliver continuous hot water to multiple fixtures 
  • Reduce utility bills in both large and small homes 

  

And yes — it’s built to last. 

Designed for Performance, Built to Last 

Rinnai tankless systems are known for their longevity and reliability. With regular care, these water heaters typically last 15 to 20 years, outlasting most tank-style units. 

Ideal for: 

  • Ontario homes with 2–3 bathrooms 
  • Families of 4+ who want more efficient hot water delivery 
  • Replacing 40–50 gallon tanks without losing comfort 
  • Homes that value space-saving wall-mounted design 

  

These units are also ENERGY STAR® certified, offering efficiency ratings up to 0.94 UEF and compatibility with energy rebates in Ontario. 

Gas vs. Electric Tankless Water Heaters – Why Rinnai Stands Out?

If you’re comparing gas vs. electric tankless water heaters, gas models like Rinnai offer: 

  

  • Higher flow rates for multiple simultaneous uses 
  • Better performance in cold climates 
  • Greater long-term cost savings with natural gas 

  

Electric units are often suited for smaller setups, but for full-home coverage in Ontario, Rinnai’s gas tankless models deliver consistent results even during winter demand peaks. 

Maintenance Tips For Long-Lasting Performance 

To ensure long-term performance: 

  

  • Flush the system annually in hard water areas 
  • Clean the inlet filter every 6–12 months 
  • Inspect venting for any blockages or buildup 
  • Schedule a yearly service check with Go Lime 

  

Regular maintenance not only preserves efficiency but also extends the life of your Rinnai unit.
