Step 1: Cut circuit breaker and water supply
The first step in installing an electric tankless water heater is to prioritize safety by cutting off the power supply. Begin by locating the circuit breaker that controls the electric current to your existing water heater. Switch off the breaker to ensure no electrical current is flowing to the unit.
Next, it is important to shut off the water supply to the old water heater. Find the main water shut-off valve, typically located near the water meter or where the water line enters your home. Turn the valve clockwise to stop the flow of water, ensuring there are no leaks or drips.
By cutting both the circuit breaker and water supply, you minimize the risk of electrical shocks and potential flooding during the installation process. Safety should always be the first priority when working with electricity and plumbing.
Step 2: Drain water heater
Before removing the old water heater, it is important to drain the water from the tank to avoid any leaks or spills. This step is crucial in ensuring a smooth and safe installation process. To drain the water heater, follow these simple steps:
- Locate the drain valve at the bottom of the water heater. It is usually a small plastic or metal valve connected to a hose.
- Place a bucket or suitable container beneath the drain valve to collect the water.
- Connect a hose to the drain valve and extend it to a suitable drainage area. Make sure the hose is securely attached.
- Open the drain valve by turning it counterclockwise. This will allow the water to flow out through the hose into the bucket or container.
- Monitor the draining process and ensure that all the water is emptied from the tank. This may take several minutes.
- Once the water is fully drained, close the drain valve by turning it clockwise.
It is recommended to refer to a guide on how to drain a water heater for more detailed instructions specific to your model. Properly draining the water heater will prevent any unwanted leaks or spills during the installation process and ensure a clean start for your new electric tankless water heater.
Step 3: Remove Front Cover
Now that the circuit breaker is safely turned off and the water supply is shut off, it's time to remove the front cover of the electric tankless water heater. This step is crucial as it will grant access to the internal components of the unit for further installation.
To remove the front cover, carefully unscrew the screws that are holding it in place. Make sure to keep track of all the screws and ensure that they are completely removed to prevent any damage to the unit. Once all the screws are removed, gently lift off the front cover and set it aside.
Removing the front cover may reveal the heating elements, control panel, and other important components. Take a moment to inspect the interior of the tankless water heater to familiarize yourself with its layout and ensure that everything is in good condition before proceeding to the next step.
