Our Comprehensive Tankless Water Heater Service Process

Our service process is designed to maximize the efficiency, lifespan, and safety of your tankless water heater, whether it is a new installation or a maintenance service.

Step 1: Sizing Assessment and Site Preparation

For new installations, we perform a detailed flow rate and temperature rise calculation to ensure the unit is correctly sized for your home’s peak hot water demand. We then prepare the site, which often involves upgrading gas lines, electrical service, and installing the specialized venting required for high-efficiency units.

Step 2: Precision Installation and Code Compliance

Our certified technicians install the unit with meticulous attention to detail, ensuring all gas, water, and venting connections are secure and compliant with local codes. We integrate the unit seamlessly into your existing plumbing system, including the installation of necessary service valves for future maintenance.

Step 3: Annual Maintenance and Descaling

Tankless water heaters require annual maintenance, primarily descaling (flushing the unit with a vinegar solution) to remove mineral buildup caused by hard water. This process is critical to maintain efficiency and prevent premature failure. We also inspect the burner assembly, heat exchanger, and all safety controls.

Step 4: System Commissioning and Performance Verification

After installation or maintenance, we commission the unit, verifying the flow rate, temperature output, and ensuring the unit is operating at its maximum efficiency. We provide a detailed walk-through of the system and discuss the long-term benefits of a tankless unit compared to a traditional Gas Water Heater or Electric Water Heater.

Tankless Water Heater Installation FAQ

  • What is the main advantage of a tankless water heater?

    The main advantage is endless hot water. Because the unit heats water on demand, it never runs out, unlike a traditional tank that can be depleted. Additionally, they are highly energy-efficient because they do not waste energy constantly heating a large tank of water.

  • How long do tankless water heaters last?

    Tankless water heaters have a significantly longer lifespan than traditional tank units, typically lasting 20 years or more with proper annual maintenance, such as descaling. This is nearly double the lifespan of a conventional tank.

  • What is the difference between a tankless water heater and a traditional tank water heater?

    A traditional tank water heater stores and constantly heats a large volume of water, leading to standby energy loss. A tankless water heater heats water instantly as it flows through the unit, only when a hot water tap is opened. This on-demand heating eliminates standby loss, making it more energy-efficient.

  • Can a tankless water heater supply my entire home?

    Yes, a properly sized tankless water heater can supply the entire home. The key is correct sizing, which is based on the maximum number of hot water fixtures that might be used simultaneously (e.g., two showers and a dishwasher). Our technicians perform a detailed sizing assessment to ensure the unit meets your peak demand.

  • Do tankless water heaters require maintenance?

    Yes, tankless water heaters require annual maintenance, specifically a process called descaling or flushing. This involves circulating a cleaning solution through the unit to remove mineral deposits (scale) that accumulate from hard water, which is essential for maintaining efficiency and preventing damage.
