Tankless electric water heaters have become increasingly popular in recent years due to their energy-efficient and space-saving design. Unlike traditional water heaters, tankless electric water heaters provide hot water on demand, making them a reliable and convenient option for households of all sizes. In this article, we will discuss how to install a tankless electric water heater in your home, step-by-step.
Introduction
Before we dive into the installation process, let’s first understand what a tankless electric water heater is and the benefits it offers. As the name suggests, a tankless electric water heater heats water without the need for a storage tank. Instead, it uses heating elements to heat the water as it passes through the unit, providing hot water on demand. This means that you can have an endless supply of hot water without the need for a bulky storage tank taking up valuable space in your home.
Additionally, tankless electric water heaters are more energy-efficient than traditional water heaters, as they only heat water when it’s needed. This can result in significant savings on your energy bills over time. With that said, let’s take a look at how to install a tankless electric water heater in your home.
Preparation
Before you begin the installation process, it’s important to gather all the necessary tools and materials you’ll need. This will ensure that you have everything you need on hand and can complete the installation without any delays. Here’s a list of tools and materials you’ll need:
