A Noritz EZ111 Pro tankless water heater installation in Southern California costs between $5,499 and $7,999, all-in. That price includes labor, materials, the city permit, and haul-away of your old unit. There are no hidden fees.

Question 2

How long does a Noritz EZ111 Pro tankless water heater last?

Question 4

How long does it take to install a Noritz EZ111 Pro tankless water heater?

Accepted Answer

A Noritz EZ111 Pro tankless water heater installation typically takes 6 to 8 hours when converting from a traditional tank water heater, depending on exhaust requirements and whether a dedicated gas line needs to be run. In many cases, a second technician is needed to run the gas line and the exhaust vent. This is a job that typically takes a full day to complete. If the home already has a tankless water heater and we are replacing one tankless with another, the installation typically takes 3 to 6 hours.

Question 5

What is the flow rate of the Noritz EZ111 Pro and how many bathrooms can it serve?

Accepted Answer

The Noritz EZ111 Pro condensing tankless water heater has a maximum flow rate of 11.1 GPM, making it the right fit for a 3 to 4 bathroom home in Southern California. It is the highest-capacity EZ-series condensing tankless water heater in the TWHC lineup.

Question 6

Why does a tankless water heater cost more to install than a traditional tank water heater?

Accepted Answer

A Noritz EZ111 Pro tankless water heater installation costs more than a traditional tank replacement because converting from a tank to a tankless requires retrofitting the existing location to be compatible with the new system. The exhaust vent must be completely replaced. A dedicated gas line must be run from the gas meter to supply the higher BTU demand required for proper functionality and longevity. Condensing tankless models require a condensate drain line with a neutralizer to be run to the exterior or another approved location. An isolation valve kit is required for annual maintenance access. California plumbing and building codes also add requirements to every installation, including bonding and grounding, installation of a thermal expansion tank, and a gas debris trap on the gas line. These are not shortcuts — they are the right way to install a tankless water heater, and they are what separate a professional installation from one that creates problems down the road.
