Welcome to our Complete Buying Guide for the Best Electric Tankless Water Heaters in 2023. Today’s technology has enabled us to use tankless water heaters, which are significantly more efficient than traditional electric hot water tanks. We have researched and compiled all the important information you need in order to decide on which of these products will be the best fit for your needs.
In this guide, we will talk about the differences between electric and gas tankless hot water heaters, along with a few other factors that can help you make an informed decision when it comes time to buy. We will also cover certain features and specs of each product, such as flow rate and BTU rating, as well as preferences when it comes to size and warranty coverage.
Explanation of electric tankless water heaters
Electric tankless water heaters are an efficient, cost effective solution for providing hot water in the home. Unlike traditional tank-style water heaters, electric tankless models heat water on demand, meaning that hot water is always available when needed without energy being wasted first heating and storing a large tank of hot water. Electric tankless units also save space as they do not require the installation of a large storage tank.
The typical electric tankless model requires an increase in incoming electrical service of up to 200 amps and a dedicated wire to provide the needed power. This style heater uses sophisticated electronics to monitor incoming flow rates and depending on the model may shut down if flow rates become too low to operate efficiently or too high for safety reasons. It is important to understand that there may be a greater initial cost associated with this style heater due to both equipment costs and upgraded electrical service upgrades; however, these are typically outweighed by the advantages in lowered energy use and improved efficiency over taking advantage of one value-priced promotion after another on big box store units.
When looking at electric tankless water heaters make sure that you look at size of heater (in gallons per minute or GPM) necessary for your household’s needs rather than just comparing prices alone. The size should take into account type and number of faucets needed simultaneously (i.e., showers, laundry machines), location(s) these appliances need their heated water (how far away from where heater will be located), as well as local climate/water temperature trends year round as colder climates may require additional backup with either inline booster heating element or cold climate compatible model specifically designed with special components such as power vents/exhaust fan motors ensuring safe released outdone gas expansion).

Factors to consider when choosing electric tankless water heaters
When choosing an electric tankless water heater, it is important to consider several factors that can influence the effectiveness and efficiency of the unit. This includes the size and power requirements of the unit, as well as its features. Additionally, it is important to know how much hot water you will need at a given time, and what type of delivery system you would like your hot water to take. The following section looks into each factor in greater detail.
- Size and Power
- The size and power of an electric tankless water heater should be chosen according to the amount of hot water that it can provide for your home or business needs. Most units are rated by their gallon-per-minute (GPM) capacity; this measurement tells you how much hot water the unit can supply at one time. It is important to choose a unit that can adequately satisfy your needs without overloading the system, as this could lead to decreased efficiency or performance issues.
- Features
- When selecting an electric tankless water heater for your home or business, consider which features are included with the unit. Some models may come with additional accessories such as adjustable temperature controls or additional safety features such as a built-in shutoff valve if temperatures exceed safe levels. Additionally, some models may include a timer so that they can be programmed automatically to turn on at specific times throughout each day in order to save energy costs by only heating when needed.
- Delivery System
- An electric tankless water heater can deliver hot water either through dedicated pipes or through storage tanks which store heated water until needed by faucets or appliances in different parts of a building.
Flow rate
Flow rate is an important factor for selecting the right electric tankless water heater. It describes how quickly a heater can deliver hot water, measured in gallons per minute (GPM).
To determine the required GPM value you will need to measure your peak hourly demand – the maximum amount of hot water you need at any given time. Flow rate also affects how many simultaneous users and appliances can be served by a water heater.
For whole house purposes, we recommend using a heater with at least 10 GPM and that can fluctuate from 8 GPM to 12 GPM depending on the volume of usage needed. Any lower than this for whole house purposes could result in uneven temperatures or reduced delivery of hot water, especially to multiple fixtures being used simultaneously.
Temperature rise
Before making a purchase, you should also consider the temperature rise of your proposed electric tankless water heater. As the name implies, temperature rise is the amount of temperature increase from incoming cold water to outgoing hot water. It is important because it determines how much hot water will be available when multiple outlets are used at once. Make sure that you choose an electric tankless heater with a temperature rise suitable for your home.
There are many factors that can affect temperature rise such as:
- Incoming and outgoing water temperatures
- Flow rate of each appliance being used
- Efficiency rating of your heater and other appliances connected to it.
Generally speaking, the higher the incoming water and outlet temperatures, the lower the total temperature rises for each appliance or combination of appliances being used simultaneously.
