Each Rinnai job is different, each home is different. Sometimes the home does not have enough gas to supply the tankless, sometimes the venting will need to be replaced. I have found that the average Rinnai Tankless Water Heater from start to finish with all parts and labor costs average to be between $5,000 to $7,000 for a single tankless.  This is of course a rough estimate and does not include any discounts.

Conventional water heaters heat water to the desired temperature all day long. The Rinnai Tankless Water Heater only heats that water as you use it. This alone helps improve the utility costs as you are only heating water instantly as you need it verse all the time, every day and even during the night.

Most Rinnai Tankless Water Heater installations that I have performed are a result of the homeowner or business wanting a higher performing, longer lasting and more efficient method to heat water. The Rinnai systems outperform all other tankless water heaters.
