Our Tankless Water Heater Installation Process
Pre-Installation Planning
Code Compliance
Every installation begins with a detailed evaluation of your home. We confirm fuel type, installation location, venting paths, and utility connections to ensure the system is properly designed from the start.
Mounting & Venting
Gas Line Setup
The unit is securely mounted with proper support and clearances. Venting is installed according to manufacturer specifications, and gas lines are verified or upgraded to handle the increased demand of a tankless system.
Water & Electrical
Condensate Connections
Hot and cold water lines are connected with service valves for future maintenance. Electrical connections are verified for safety, and condensate drainage is installed when required.
Testing & Startup
System Calibration
Before completing the job, we test all connections, inspect venting, restore utilities, and verify proper operation. Hot water temperature and system performance are checked at multiple fixtures.
Gas Tankless Water Heater Installation & Safety Standards
A gas tankless water heater installation requires careful attention to safety. These systems often require larger gas supply lines, proper sediment traps, and precise venting to operate correctly. Our plumbers follow strict safety protocols to ensure your system operates reliably and efficiently without risk to your home.
Tankless Water Heater Replacement & Upgrades
Replacing a traditional tank water heater with a tankless system is a popular upgrade. We safely remove your old unit, evaluate existing connections, and make any necessary upgrades to support the new system. The result is a modern hot water solution that delivers consistent performance and long-term value.

Frequently Asked Questions
How long does tankless water heater installation take?
Most tankless water heater installations take 4–8 hours. If upgrades are needed (like gas line sizing, venting changes, or electrical updates), it could take a full day. Replacing an existing tank with a tankless system typically requires additional adjustments to ensure everything meets code and operates safely.
Do I need a gas line upgrade for a tankless water heater?
Possibly. Tankless units require more BTUs than traditional tank heaters, so many homes need a larger gas line to supply enough fuel. A professional assessment will determine if your current gas line can handle the demand or if an upgrade is necessary for safe, efficient operation.
How much does tankless water heater installation cost?
Installation typically ranges from $3,000–$6,500, depending on: Gas line upgrades, venting requirements, electrical work, brand and unit size, and location of installation. While the upfront cost is higher than a traditional tank heater, tankless systems often last longer and can lower energy bills over time.
How often should a tankless water heater be flushed?
A tankless system should be professionally flushed once a year to remove mineral buildup (especially in areas with hard water). Regular maintenance helps maintain efficiency, extend lifespan, and prevent costly repairs.
Can a tankless water heater supply hot water to multiple fixtures?
Yes — as long as it’s properly sized. A correctly sized tankless unit can supply hot water to multiple showers, sinks, and appliances at the same time. The key is matching the unit’s flow rate (GPM) to your household’s peak hot water demand.
