Upgrading to a tankless water heater under your kitchen sink can be a game-changer for your home, providing endless hot water on demand without the hassle of a bulky storage tank. While the process may seem daunting, with the right tools and a step-by-step guide, you can tackle this DIY project with confidence. This comprehensive guide will walk you through every step of the installation process, ensuring a seamless transition to your new water heating system.

Step 1: Gather Your Materials

Before you begin, gather all the necessary materials:

• Tankless water heater
• Electrical wire (12-gauge or thicker)
• Electrical conduit
• Water supply lines (flexible or copper)
• Gas supply line (if using gas-powered heater)
• Vent pipe (if using gas-powered heater)
• Drain pan
• Mounting bracket
• Screwdriver
• Wrench
• Pliers
• Pipe cutter
• Wire strippers

Step 2: Choose the Right Location

Select a location under your kitchen sink that provides ample space for the water heater and allows for easy access to the connections. Ensure that the area is well-ventilated, especially if using a gas-powered heater.

Step 3: Mount the Water Heater

Install the mounting bracket on the wall or cabinet under the sink. Carefully lift the water heater into place and secure it to the bracket using the provided hardware.

Step 4: Connect the Water Supply Lines

Cut the water supply lines to the appropriate length and connect them to the water heater‘s inlet and outlet ports. Use wrenches to tighten the connections securely.

Step 5: Connect the Gas Supply Line (Gas-Powered Heaters Only)

If using a gas-powered heater, connect the gas supply line to the heater’s gas inlet port. Ensure that the connection is leak-free using a gas leak detector.

Step 6: Install the Vent Pipe (Gas-Powered Heaters Only)

Connect the vent pipe to the heater’s exhaust port and extend it to the outside of the building. Ensure that the pipe is properly sealed and slopes downward to prevent condensation buildup.

Step 7: Connect the Electrical Wires

Connect the electrical wires to the heater’s electrical terminals. Use wire strippers to expose the wire ends and insert them into the terminals. Tighten the screws to secure the connections.

Step 8: Install the Drain Pan

Place the drain pan under the water heater to collect any potential leaks. Ensure that the drain pan is large enough to catch any dripping water.

Step 9: Test the System

Turn on the water supply and gas supply (if using gas-powered heater). Open the hot water faucet to allow water to flow through the heater. Check for any leaks or abnormal noises.

Troubleshooting Tips

• If the water heater is not heating properly, check the gas supply, electrical connections, and water flow.
• If there is a leak, tighten the connections or replace the faulty component.
• If the heater is making strange noises, contact the manufacturer for assistance.
