These innovative devices provide hot water on demand, saving energy and space while ensuring you have a constant supply of hot water. To help you make an informed decision, this buying guide will walk you through the key factors to consider when choosing the best electric tankless water heater for your needs.

Water Heater Type

a. Whole-House or Point-of-Use

• Whole-House: These electric tankless water heaters are designed to supply hot water to your entire home. They are suitable for large households and can handle multiple applications simultaneously.
• Point-of-Use: smaller units that are installed closer to the point of use, like sinks or showers. These are ideal for smaller households or for specific hot water needs, such as a remote bathroom.

Flow Rate (GPM)

The flow rate, measured in gallons per minute (GPM), indicates how much hot water the heater can deliver. Consider your household’s hot water demands to choose the right GPM for your needs. A higher GPM is necessary for larger families and homes with multiple hot water appliances.

Temperature Rise

Look for water heaters with a high energy efficiency rating. Electric tankless water heaters are already more energy-efficient than traditional tank-style heaters, but some models are more efficient than others. Energy Star-certified models are a good choice, as they meet strict efficiency standards.

Installation

Consider the ease of installation and the availability of suitable electrical connections. Some tankless water heaters may require substantial electrical upgrades, which can add to the installation cost. If possible, choose a unit that fits your existing electrical setup.

Find out what maintenance is required for the unit you’re considering. Many electric tankless water heaters are relatively low maintenance, but they may need occasional descaling or cleaning to maintain efficiency.

In most cases, it’s advisable to have your electric tankless water heater professionally installed. Certified plumbers or electricians can ensure the unit is correctly installed, reducing the risk of issues down the line.

Local Regulations

Check your local building codes and regulations regarding the installation of electric tankless water heaters. Compliance with local codes is essential for safety and to avoid potential issues in the future.
