Why Consider a Tankless Water Heater for Your Brentwood Home?
Tankless water heaters, also known as on‑demand water heaters, offer significant advantages over their traditional counterparts, making them an excellent investment for many homeowners in Brentwood:
- Continuous Hot Water on Demand: Unlike tank models that can run out of hot water, tankless units heat water instantly as needed, providing an endless supply for simultaneous showers, laundry, and dishwashing without interruption.
- Significant Energy Bill Savings: By heating water only when it's needed, tankless units avoid the standby energy losses associated with traditional tanks constantly keeping water hot. This efficiency can lead to noticeable reductions in your monthly utility bills.
- Compact, Space‑Saving Design: Tankless water heaters are much smaller than bulky storage tank models, allowing for flexible installation in various locations, freeing up valuable space in your garage, utility closet, or basement.
- Extended Lifespan & Reliability: With proper maintenance, tankless water heaters typically last 15 to 20 years or more, significantly longer than traditional tanks (which average 8–12 years). This longevity translates to a greater return on your investment.

Signs You Need a Water Heater Replacement
Stewart Heating, Plumbing & Air Conditioning recommends paying attention to these common indicators:
- Unit Age: Traditional tank water heaters typically last 8–12 years, while tankless models can last 15–20 years or longer. If your unit is nearing or has surpassed these averages, replacement is often more cost‑effective than continued repairs.
- Frequent Repairs or High Repair Costs: If you're consistently calling for Plumbing Service or if the cost of a single repair approaches half the price of a new unit, it's time to consider replacement.
- Inconsistent Hot Water or Running Out Too Quickly: For tank models, this signals sediment buildup or a failing heating element. For tankless units, it might indicate sizing issues, mineral buildup, or component failure.
- Leaks, Rust, or Unusual Noises: Puddles around your unit, rusty water, or strange banging, rumbling, or popping sounds can all be signs of internal corrosion or significant wear, often necessitating replacement.
- Desire for Modern Efficiency & Comfort: Even if your current unit isn't failing, upgrading to a new, highly efficient tankless model can significantly improve your home's comfort and reduce energy consumption.
Our Seamless Tankless Water Heater Replacement Process
Replacing a water heater, especially upgrading to a tankless system, requires specialized knowledge and adherence to local codes. Stewart Heating, Plumbing & Air Conditioning follows a professional process to ensure a smooth and efficient transition:
- Personalized Consultation & Assessment
Our expert plumbers begin with a thorough assessment of your current hot water usage, household size, and existing plumbing, gas, and electrical infrastructure. This helps us determine the ideal tankless unit size and type for your Brentwood home and evaluate the best placement for the new unit, considering venting requirements and accessibility. - Expert Unit Selection
We guide you through choosing the perfect tankless water heater—natural gas, propane, or electric. We discuss top brands and their features, such as flow rate, efficiency ratings (Energy Factor or Uniform Energy Factor), and smart technology, ensuring the chosen unit aligns with your budget and requirements. - Preparation & Permitting
Tankless water heater installations often require specific permits in Brentwood and Contra Costa County. Our team handles all necessary permitting paperwork to ensure compliance with local building and safety codes. We also prepare the work area, safely shutting off utilities and protecting your property. - Safe Removal of Your Old Unit
We meticulously drain and disconnect your old tank or tankless water heater. Our technicians ensure safe, environmentally responsible disposal of the old unit, minimizing any hassle for you. - Precision Tankless Installation
This critical step involves professional plumbing connections for reliable hot water delivery, expert gas line or dedicated electrical circuit installation, and precise venting setup. Proper venting is crucial for gas units; our team adheres to strict safety protocols for all installations. - Testing, Calibration & Customer Walkthrough
Once installed, we thoroughly test the new tankless water heater to ensure proper function, optimal efficiency, and leak-free operation. We calibrate the unit and then provide a detailed walkthrough of your system’s operation, features, and Plumbing Maintenance tips to ensure longevity and efficiency.
