Steps for Tankless Water Heater Installation Preparation 

Below are the steps from preparing to set up your water heater to complete the installation process seamlessly. Ensure you choose a suitable location, gather the necessary tools and materials, and follow manufacturer instructions for a successful installation. 


Step 1: Assess Your Home’s Needs

Assessing your home’s hot water requirements is crucial before installing. Consider factors such as the number of occupants, peak demand times, and existing plumbing infrastructure. Our experts at Kerivan-Lane, Inc. can help you determine the right size and model of tankless water heater to meet your household’s needs efficiently.


Step 2: Choose the Right Location for Your Water Heater

Selecting the optimal location for your tankless water heater is essential for maximizing performance and convenience. Look for a well-ventilated area with easy access to gas and water lines, preferably near the point of use, to minimize heat loss in transit. Our experienced technicians can help you identify the ideal placement for your new tankless water heater, ensuring optimal functionality and safety.


Step 3: Prepare the Water Heater Installation Site

Once you’ve chosen a location, prepare the installation site by clearing the area and ensuring adequate space for the unit and any necessary venting components. If retrofitting, carefully remove the existing water heater and disconnect the plumbing and gas lines. At Kerivan-Lane, Inc., our skilled installers take every precaution to safeguard your home and ensure a smooth installation process from start to finish.


Step 4: Install the Tankless Water Heater

With the site prepared, installing the tankless water heater is time. Begin by mounting the unit securely to the wall using manufacturer-approved brackets. Next, the gas and water lines must be connected according to local building codes and manufacturer specifications. Our certified technicians at Kerivan-Lane, Inc. have the expertise to handle these connections safely and efficiently, ensuring proper function and compliance with all regulations.


Step 5: Ensure Proper Venting and Exhaust

Proper venting is critical for the safe operation of a tankless water heater. Venting requirements may vary depending on the unit’s location and fuel type. Install vent pipes to exhaust combustion gasses safely outdoors, following local building codes and manufacturer guidelines. We prioritize safety and compliance, ensuring your tankless water heater is correctly vented to protect your home and family.


Step 6: Test and Commission

Once the installation is complete, it’s time to test and commission the tankless water heater. Turn on the unit and check for plumbing and gas connection leaks. Adjust temperature settings as needed and verify that hot water flows consistently at the desired rate. Our technicians at Kerivan-Lane, Inc. perform thorough testing to ensure that your tankless water heater operates flawlessly, providing endless hot water whenever you need it.


Step 7: Enjoy Endless Hot Water With Your New Water Heater

With your new tankless water heater installed and commissioned, you can enjoy endless hot water and energy savings. Say goodbye to cold showers and hello to consistent comfort and efficiency.

Post-Installation Steps for Your Tankless Water Heater 

Now that we’ve successfully set up the water heater and completed the installation process, it’s time to explore the steps you can take post-installation to ensure optimal performance and longevity.


Step 1: Educate Yourself on Water Heater Maintenance

To maintain your tankless water heater effectively, it’s essential to educate yourself on proper maintenance techniques and troubleshooting tips. Familiarize yourself with the owner’s manual and follow recommended maintenance procedures outlined by the manufacturer. Kerivan-Lane, Inc. is here to support you every step of the way, providing guidance and resources to help you keep your tankless water heater in top condition for years to come.


Step 2: Schedule Regular Maintenance for Your Water Heater

It’s essential to schedule regular maintenance checks to ensure optimal performance and longevity of your tankless water heater. At Kerivan-Lane, Inc., we offer comprehensive maintenance plans to keep your system running smoothly year-round. Our technicians will inspect the unit, flush the heat exchanger to remove mineral buildup, and check for potential issues. By staying proactive with maintenance, you can prevent costly repairs and extend the lifespan of your tankless water heater.


Step 3: Monitor Your Water Heater’s Energy Usage

One key benefit of a tankless water heater is its energy efficiency. By heating water only when needed, these systems can significantly reduce energy consumption compared to traditional tank-style heaters. To maximize energy savings, monitor your tankless water heater’s energy usage and adjust temperature settings as needed. 


Step 4: Consider Additional Upgrades for Your Water Heater

While installing a tankless water heater offers numerous benefits, there are additional upgrades you can consider for your home’s efficiency and comfort. For example, installing a recirculation pump can minimize wait times for hot water, ensuring instant hot water at every faucet. Integrating a smart thermostat or remote control system allows you to monitor and adjust your water heater’s settings from anywhere, adding convenience and control to your daily routine.

Step 5: Plan for Long-Term Savings

Investing in a tankless water heater is beneficial for immediate comfort and long-term savings. While the initial cost may be higher than traditional water heaters, tankless models’ energy efficiency and durability result in lower utility bills and reduced maintenance expenses. By planning for these long-term savings, homeowners can make a wise investment that pays off in the coming years, providing financial and environmental benefits.


Step 6: Explore Rebate and Incentive Programs

Many utility companies and government agencies offer rebates and incentives for homeowners who upgrade to energy-efficient appliances such as tankless water heaters. These programs can offset the initial cost of installation and provide additional savings in the form of tax credits or cash incentives.


Step 7: Schedule Regular System Inspections

To ensure your tankless water heater’s continued efficiency and longevity, schedule regular inspections with Kerivan-Lane’s expert technicians. During these inspections, our team will thoroughly assess your system, check for any signs of wear or damage, and perform preventive maintenance to keep it operating at peak performance. By staying proactive with inspections and maintenance, you can extend the lifespan of your system and avoid costly repairs down the road.


Step 8: Regularly Check for Leaks and Issues

Even after installation, checking for potential leaks or issues with your tankless water heater is important. Look for signs of water leakage around the unit, unusual sounds, or fluctuations in water temperature. Addressing any issues promptly can prevent damage to your home and ensure that your tankless water heater continues to operate smoothly. We offer prompt repair services to address any problems that may arise, keeping your system running efficiently.


Step 9: Consider Water Quality Factors

Water quality can significantly impact the performance and lifespan of your tankless water heater. Hard water, which contains high levels of minerals such as calcium and magnesium, can lead to scale buildup within the unit, reducing efficiency and potentially causing damage. Consider installing a water softener or descaling system to prevent scale buildup and protect your tankless water heater investment.


Step 10: Prepare for Emergency Situations

While tankless water heaters are known for their reliability, it’s essential to be prepared for emergencies that may arise. Familiarize yourself with the location of the gas and water shut-off valves, as well as any emergency procedures outlined in the owner’s manual. In the event of a gas leak or other emergency, knowing how to shut off the supply quickly can help prevent accidents and protect your home and family. 


Step 11: Stay Informed About Warranty Coverage

Most tankless water heaters come with manufacturer warranties that cover parts and labor for a specified period. Familiarize yourself with the terms and conditions of your warranty coverage, including any regular maintenance or servicing requirements. At Kerivan-Lane, Inc., we can help you understand your warranty coverage and ensure you meet any maintenance obligations to keep your warranty valid. Our goal is to provide peace of mind and reliable support throughout the life of your tankless water heater.


Step 12: Share Your Experience

Once your tankless water heater installation is complete and you’re enjoying the benefits of endless hot water, consider sharing your experience with others. Word-of-mouth recommendations and online reviews can help other homeowners make informed decisions about upgrading to a tankless system. By sharing your satisfaction with Kerivan-Lane, Inc.’s expert installation and superior service, you can help others experience the comfort and efficiency of a tankless water heater in their homes.
