If you're looking for a more energy-efficient way to heat your water, a tankless electric water heater might be the solution you need. Unlike traditional water heaters that store hot water in a tank, tankless electric water heaters heat water on demand, providing hot water only when you need it. This means you're not wasting energy keeping a tank of water hot all day long, and you'll have hot water whenever you need it.

At Wilson Plumbing, we specialize in plumbing, heating, cooling, and electric services in Northeast Ohio, and we recommend tankless electric water heaters to our clients who are looking for a more energy-efficient way to heat their water. Not only do these systems use less energy than traditional water heaters, but they also last longer and take up less space. Plus, with a tankless electric water heater, you'll never run out of hot water.

If you're interested in installing a tankless electric water heater in your home, our team of experts at Wilson Plumbing can help. We'll work with you to determine the right size and type of water heater for your needs, and we'll install it quickly and efficiently. With our help, you'll have hot water on demand and a more energy-efficient home in no time.

Preparation and Safety

Before installing a tankless electric water heater, it is important to follow proper preparation and safety procedures. This includes understanding local building codes, gathering necessary tools and materials, and taking safety precautions.

Understanding Local Building Codes

Local building codes vary by location, so it is important to research and understand the specific codes in your area. This will ensure that your installation is up to code and safe. Failure to comply with local building codes can result in fines or even danger to your home and family.

Gathering Necessary Tools and Materials

To install a tankless electric water heater, you will need a variety of tools and materials. These may include:

  • Pipe cutter
  • Adjustable wrench
  • Screwdrivers
  • Teflon tape
  • Copper pipes
  • Electrical wiring
  • Circuit breaker

Having all of the necessary tools and materials on hand before beginning the installation process will help ensure a smooth and efficient installation.

Safety Precautions and Professional Considerations

Installing a tankless electric water heater can be a complex and potentially dangerous process. It is important to take proper safety precautions, such as turning off the electricity and water supply before beginning the installation.

Additionally, it is recommended to seek professional installation from a licensed plumber or licensed electrician. This will ensure that the installation is done safely and up to code.

Installation Process Overview

Installing a tankless electric water heater can be a complex process, but with the right tools and knowledge, you can do it yourself. In this section, we will provide an overview of the installation process, including assessing the installation area, mounting the water heater, and making plumbing connections.

Assessing Installation Area

Before installing the water heater, it is important to assess the installation area. You should choose a location that is easily accessible and has enough space for the water heater. Make sure the location is near the main water and gas lines to avoid additional plumbing work. Also, ensure the area is well-ventilated to prevent any carbon monoxide buildup.

Mounting the Water Heater

Once you have chosen the installation area, it's time to mount the water heater. The mounting process varies depending on the type of water heater you have. For instance, some water heaters require wall mounting, while others need to be installed on the floor. Follow the manufacturer's instructions carefully to ensure the water heater is mounted correctly.

Making Plumbing Connections

After mounting the water heater, the next step is to make plumbing connections. This involves connecting the water and gas lines to the water heater. Make sure you use appropriate fittings to prevent any water leakage. Also, ensure the connections are secure to avoid any future issues.

When it comes to installation, it's always best to hire a professional plumber to ensure the job is done correctly.

Final Steps and Testing

Congratulations, you have successfully installed your new tankless electric water heater! But before you start enjoying the benefits of endless hot water, there are a few final steps to take.

Checking for Leaks and Functionality

First, check for any leaks around the unit and connections. Turn on the water supply and power to the unit, and run hot water from a faucet for a few minutes. Check the unit and connections for any signs of leakage. If you notice any leaks, turn off the water supply and power to the unit and contact a professional plumber like Wilson Plumbing for assistance.

Next, test the functionality of the unit. Make sure the hot water is flowing properly and that the water pressure and flow rate are sufficient. Refer to the manufacturer's instructions to adjust the flow and pressure valves if necessary.

Final Inspection and Warranty Registration

Once you have confirmed that the unit is functioning properly, perform a final inspection of the installation. Ensure that all connections are secure and that the unit is properly grounded. Refer to the manufacturer's instructions for any additional steps required for your specific unit.

Finally, register your warranty with the manufacturer. This will ensure that you are covered in case of any defects or issues with the unit. Keep a copy of the warranty registration and any other relevant documents in a safe place.
