Our Precision Gas Water Heater Replacement Process

Our replacement service is a comprehensive, multi-step procedure designed to ensure optimal performance and safety from day one.

Step 1: Comprehensive Assessment and Sizing

We begin with a thorough assessment of your current unit’s condition and your household’s hot water needs. We use the latest sizing calculations to recommend a new gas water heater with the correct First-Hour Rating (FHR) and energy factor, ensuring it meets your demand while maximizing efficiency. We also check the installation location for compliance with current building codes.

Step 2: Safe Removal and Site Preparation

Safety is our top priority. We safely shut off the gas and water supply, drain the old tank, and disconnect the gas and vent lines. The old unit is removed and disposed of according to environmental regulations. We then prepare the site, ensuring the new unit’s base is level and secure, and that all necessary safety features, such as the T&P (Temperature and Pressure) relief valve, are in place.

Step 3: Precision Installation and Code Compliance

The new gas water heater is installed, and the water lines are connected. Our certified technicians meticulously handle the gas line connection and venting, which is the most critical step. We ensure a leak-free gas connection and correctly install the vent pipe to safely exhaust combustion gases, guaranteeing compliance with all local building codes.

Step 4: System Commissioning and Client Education

We turn on the gas and water supply, check for leaks, and test the system to ensure the burner is firing correctly and the water is heating to the set temperature. We provide a full orientation on the unit’s operation, including the importance of annual Gas Water Heater Maintenance to preserve the warranty and safety. If the old unit was leaking, we also recommend a Plumbing Inspection to check for any secondary damage.

Gas Water Heater Replacement FAQ

What are the clearest signs that my gas water heater needs replacement, not just repair?

The clearest signs are age over 12 years, leaking from the tank itself (which is irreparable), and rusty or discolored hot water, which indicates severe internal corrosion.
How long does a gas water heater replacement typically take?

A standard gas water heater replacement typically takes between 4 to 6 hours. This includes the time for draining the old tank, installing the new unit, connecting the gas and water lines, and ensuring all safety checks are complete.
Is it necessary to replace my gas water heater with another gas model?

No. While many homeowners prefer to stick with gas for its fast recovery rate, this is an ideal time to consider a high-efficiency Tankless Water Heater or a heat pump water heater, depending on your home’s infrastructure and energy goals.
Does replacing my old unit save me money on utility bills?

Yes. Modern gas water heaters have significantly higher Energy Factor (EF) ratings than units 10-15 years old. Replacing an old, inefficient unit can lead to substantial savings on your monthly gas bill due to reduced energy consumption.
What is the most important safety consideration during a gas water heater replacement?

The most important safety consideration is the venting of combustion gases. Improper venting can lead to the buildup of deadly carbon monoxide (CO) inside the home. Professional installation ensures the vent is correctly sized and sealed.
