Installing a tankless water heater in your home can be a great way to save energy and money while ensuring you never run out of hot water. Tankless water heaters are more efficient than traditional tank water heaters because they only heat water as it is needed, eliminating the standby heat loss associated with tanks. In this guide, we will walk you through the steps to install a tankless water heater in your home.
Pre-Installation Considerations
- Determine the Right Size: Before purchasing a tankless water heater, calculate your household’s peak demand for hot water. This will help you determine the appropriate size unit for your needs.
- Choose the Location: Select a location for your tankless water heater that allows for proper venting and access to gas and water lines. Ideally, it should be close to the main point of use to minimize hot water pipe length.
- Check Local Codes: Make sure to check local building codes and regulations before installing a tankless water heater to ensure compliance with safety and installation requirements.
- Prepare Installation Tools: Gather all necessary tools for the installation process, including pipe wrenches, tubing cutters, gas leak detector solution, and a screwdriver.
Installation Process
- Turn off Utilities: Before starting the installation, shut off the gas and water supply to your home to prevent accidents and leaks.
- Remove Old Water Heater: If replacing a traditional water heater with a tankless unit, turn off the power supply and disconnect the old water heater. Drain it completely and remove it from its location.
- Mount the Tankless Water Heater: Securely mount the tankless water heater to the wall, making sure it is level and stable. Follow the manufacturer’s instructions for proper mounting.
- Connect Water Lines: Use copper tubing or flexible hoses to connect the water lines to the tankless water heater. Make sure to follow the manufacturer’s guidelines for proper sizing and connection.
- Connect Gas Line: Install a new gas line if necessary and connect it to the tankless water heater using a gas leak detector solution to ensure there are no leaks.
- Install Venting System: Install the venting system for the tankless water heater according to the manufacturer’s instructions. Venting requirements may vary based on the type of unit you are installing.
- Adjust Temperature: Set the desired water temperature on the tankless water heater and adjust the settings for optimal performance.
- Test the System: Turn on the gas and water supply to the tankless water heater and test the system for leaks or malfunctions. Make any necessary adjustments to ensure proper operation.
Post-Installation Maintenance
- Flush the System: Regularly flush the tankless water heater to remove mineral deposits and maintain its efficiency. Follow the manufacturer’s recommendations for flushing intervals.
- Check for Leaks: Periodically check for leaks in the gas and water lines to prevent potential damage and ensure the safe operation of the tankless water heater.
- Inspect Venting System: Inspect the venting system for any blockages or obstructions that could impede proper airflow and ventilation.
