Selecting the Ideal Location for Your Electric Tankless Water Heater

-- When it comes to choosing the right water heating solution for your home, electric tankless water heaters are gaining popularity for their energy efficiency and on-demand hot water capabilities. However, to fully reap the benefits of this technology, it's crucial to select the ideal location for installation. The placement of your electric tankless water heater can significantly impact its performance, energy efficiency, and overall convenience. In this blog, we'll guide you through the process of selecting the perfect spot for your electric tankless water heater.

Consider Safety First

Safety should be your top priority when selecting a location for your electric tankless water heater. Ensure that it complies with local building codes and manufacturer's guidelines. Here are some safety considerations to keep in mind:

  • Install the unit in a well-ventilated area to prevent the accumulation of gases, and to dissipate excess heat.

  • Keep it away from flammable materials and sources of open flames.

  • Install it at a height that's inaccessible to children and pets.

  • Assess Accessibility

  • Accessibility is another crucial factor to consider. Choose a location that provides easy access for installation, maintenance, and repairs. A location that's too difficult to reach can lead to increased labor costs if you ever need service on your unit. Make sure there's enough clearance around the unit for plumbers or technicians to work comfortably.

Determine Flow Rate and Distance

To ensure you have adequate hot water flow at all fixtures and appliances, consider the distance between your electric tankless water heater and your points of use (sinks, showers, and other hot water outlets). Longer distances can result in delays in receiving hot water. Plan the installation to minimize these delays and reduce the amount of wasted water while waiting for hot water to arrive.

Electrical Requirements

Electric tankless water heaters require specific electrical requirements, and you must choose a location that can meet these needs. Ensure there is an appropriate electrical circuit, with the right voltage and amperage, available at your chosen location. If the electrical panel is far from your desired location, be prepared to invest in wiring and circuit upgrades to meet the unit's needs.

Water Quality

Water quality can significantly impact the performance and lifespan of your tankless water heater. Avoid installing it in areas with hard water as mineral buildup can reduce efficiency and cause maintenance issues. Consider using a water softening system if hard water is prevalent in your region.

Environmental Considerations

Tankless water heaters are eco-friendly due to their energy efficiency, but the installation location can further enhance their environmental impact. Placing your unit in an area with a reliable source of renewable energy, such as solar power, can make your hot water system even more sustainable.

Aesthetics and Space

Consider how the installation will impact the aesthetics of your home. Tankless water heaters are typically smaller and more compact than traditional tanks, making it easier to find a discreet location. You can choose to install it under a sink, inside a closet, or even outdoors with proper protection.


Selecting the ideal location for your electric tankless water heater is a crucial decision that impacts safety, convenience, and efficiency. By considering factors such as safety, accessibility, flow rate, electrical requirements, water quality, environmental considerations, and aesthetics, you can ensure that your electric tankless water heater operates at peak performance, providing you with energy-efficient and on-demand hot water for years to come. Proper installation and placement will help you make the most of this modern water heating technology and improve your overall home comfort.
