Our Tankless Water Heater Installation Process

We dispatch a fully stocked mobile warehouse with every Navien tankless component. Our box vans carry the mounting hardware, venting materials, and gas line fittings—circulating through Greater Houston so we complete your installation in one trip.

1

Step 1: Initial Consultation and System Sizing

We start with a thorough assessment of your home's hot water demands, plumbing infrastructure, and venting options. Our MPL-38162 licensed plumbers calculate your exact BTU requirements to recommend the perfect Navien tankless model for your needs. No guesswork—just precise sizing for optimal performance.

Step 2: Safe Removal of Old Water Heater

Our licensed plumbers safely disconnect, drain, and remove your old tank-style water heater. We clear the space for your new, compact unit while protecting your floors and walls. Clean removal means clean installation.

3

Step 3: Mounting and Venting Installation

We securely mount the new tankless unit and install the necessary high-efficiency venting system. Our mobile warehouse carries all mounting brackets and venting components—ensuring safe and proper exhaust of gases. Permanent mounting, permanent solution.

4

Step 4: Gas and Water Line Connection

We professionally connect the water lines and perform any necessary gas line upgrades. Our trucks stock the proper pipe fittings and gas connectors to ensure your new unit has the correct fuel supply for optimal, consistent performance. We don't chase parts. We bring them with us.

5

Step 5: Condensate Drain Setup

A dedicated condensate drain line is installed to safely manage the moisture created by the high-efficiency condensing process. This protects your home and the unit from water damage. Proper drainage prevents future problems.

6

Step 6: System Commissioning and Final Walkthrough

We power up the unit, run a full diagnostic test, and commission the system to manufacturer specifications. Our licensed plumbers then walk you through its operation and answer any questions. One trip. Done.
