Preparing for Installation

Installing a water heater, especially an electric tankless one, requires careful preparation. At Sanz Plumbing, we understand the importance of the initial steps of the installation process and how they can impact the entire project. Let’s walk you through these steps.

Safety Measures: Switching Off Circuit Breaker and Water Supply

The first step to install an electric tankless water heater is to ensure safety. This means switching off the circuit breaker and water supply. Cutting off the power is crucial to avoid any accidental electric shocks while working, while shutting off the water supply prevents any potential flooding during the installation process.

As pointed out in our research, flooding can lead to thousands of dollars in damage, which makes this step paramount in the installation process. It’s not just about saving time and money; it’s about making sure you can work safely and efficiently.

Draining and Disconnecting the Old Water Heater

If you’re replacing a tank-type water heater, the next step is to drain it and disconnect it. Draining helps prevent any water spillage that could damage your property or create a mess. As referenced in the research, this process requires a hose and a container, like a bucket.

Once the water heater is drained, you can then unscrew the connecting pipes and remove the old wiring and wall-mounting brackets. But remember: caution is key. The old wiring and pipes should not be damaged during this process. If they are, replacements will be necessary, which could add to the project timeline and costs.

Importance of Not Damaging Connecting Pipes

During this phase, it’s critical to protect the integrity of the connecting pipes. Damaged pipes can lead to leaks and other issues that could hinder the proper functioning of your new water heater.

At Sanz Plumbing, we emphasize the importance of careful handling during the disconnection process. It’s not just about getting the old water heater out; it’s about preparing the space for the new unit in such a way that it supports optimal performance.

In the next section, we’ll guide you through the actual installation process, where we’ll be connecting the new unit and ensuring it’s properly mounted and ready to provide you with efficient hot water supply. The journey to understanding how to install an electric tankless hot water heater continues, and we’re here to guide you every step of the way.

Installation Process

Now that we’ve prepared for installation, it’s time to get into the heart of the matter. We’ll guide you through each step of the installation process.

Removing the Front Cover of the New Tankless Unit

First things first, you need to remove the front cover of the new tankless unit. Use a screwdriver to carefully remove the screws, placing them in a safe spot so you won’t lose them. As we often remind our clients, every part is crucial for the optimal operation of your water heater. Be extra careful if there are any cables connected between the cover and the unit. Unplug these gently before fully removing the cover.

Mounting the Unit to a Wall

Next, you’ll need to mount the unit to the wall. Make sure to choose a clean, uncluttered area for installation. Also, ensure that the unit is within easy reach in case of an emergency. Mounting the water heater is a straightforward task. You can use screws and the mount included in the package. Just follow the instructions provided with your unit.

Connecting Pipes for Hot Water Distribution

Once the device is mounted, it’s time to connect the pipes that distribute hot water throughout your home. These connections will go in and out of your water heater, located towards the bottom of the unit. If you received an installation diagram with your unit, refer to it to determine exactly where the connections should go.

Installing Flow and Pressure Valves

The next step in understanding how to install an electric tankless hot water heater is to install flow and pressure valves. These valves are crucial for regulating the flow and pressure of water going through your heater.

Bleeding the Hot Water System to Remove Air

Lastly, ‘bleed’ your hot water system to remove any trapped air. Air in the system can cause a banging or rattling noise often referred to as ‘water hammer’. It’s also an essential step to ensure the smooth operation of your water heater.

In the next section, we will discuss the electrical connections and how to safely establish them.

Electrical Connections

After connecting the pipes and allowing the system to bleed, it’s time to focus on the electrical connections of your tankless water heater. It’s crucial to remember that electricity can be dangerous if not handled correctly, so it’s advisable to contact a professional electrician if you’re unsure about this step. Sanz Plumbing has a team of experienced professionals who can ensure the electrical connections in your water heating system are safe and efficient.

Inspecting Electrical Connections

Before you proceed, carefully inspect all the electrical components of the water heater. Make sure there are no damaged or frayed wires, and double-check that all the components are firmly connected. It’s important to ensure that the electrical connections are safe and securely fastened to prevent any electrical issues down the line.

If you come across any damaged wires or loose connections, don’t hesitate to contact us at Sanz Plumbing. We can provide prompt and efficient repair services to ensure your water heater is working perfectly.

Reattaching the Cover

Once the inspection is complete, it’s time to reattach the front cover of the unit. Using the screws that you safely put aside earlier, firmly fix the cover back in place. Be cautious not to over-tighten the screws as it might damage the cover or the unit.

Switching On the Circuit Breaker

The final step in how to install an electric tankless hot water heater is to switch the circuit breaker back on. This step should only be performed after you’ve double-checked all connections and reattached the front cover.

Once the circuit breaker is on, your water heater should start working. However, you should give it a few minutes to heat the water before you start testing it.

Safety should be your top priority when handling electrical components. If at any point you feel unsure or uncomfortable with the process, don’t hesitate to reach out to us at Sanz Plumbing. We’re here to help ensure the installation process is smooth, safe, and efficient.

Post-Installation Checks

Once your electric tankless water heater is installed, you’re not quite done. There are a couple of crucial checks that need to be done to ensure your unit is functioning correctly and safely.

Configuring the Temperature Settings

The first check involves the temperature settings. As you switch on your water heater, you’ll want to ensure that the system’s temperature settings are correctly configured. These units can indeed get very hot when set at the highest settings, so it’s recommended to avoid using them this high to prevent potential burns (homeserve.com).

We at Sanz Plumbing suggest starting at a moderate temperature setting and adjusting it gradually as needed. The goal is to provide sufficient hot water for your needs without risking scalding or unnecessary energy consumption.

Testing All Hot Water Outlets in the Home

The second check involves testing all hot water outlets in your home, including faucets, showers, dishwashers, and clothes washers. This step ensures that all connections are correct and that hot water is being distributed evenly and quickly throughout your property.

Turn on each outlet one by one and observe the water temperature. It should heat up quickly and reach a comfortable temperature. If the water is too hot, you may want to adjust the temperature settings down. If there’s no hot water, or if it’s taking longer than expected to heat up, this might indicate an issue with the installation that needs to be addressed.

While this might seem like a lot of work, especially if you’re eager to start using your new water heater, these post-installation checks are crucial to ensure the safe and efficient operation of your unit. Knowing how to install an electric tankless hot water heater involves not only the installation process but also understanding how to properly test and adjust it post-installation.

At Sanz Plumbing, we’re committed to providing our clients with comprehensive support, from the choice of the best water heater for their needs through installation and post-installation checks. If you’re unsure about any aspect of your water heater installation or adjustment, don’t hesitate to contact us. Our team of experienced professionals is always ready to help.
