Introduction

A tankless water heater, also known as an on-demand water heater, is an increasingly popular choice for homeowners looking to upgrade their water heating system. Unlike traditional water heaters that store and heat a large amount of water in a tank, tankless water heaters heat water directly as it passes through the unit, providing a continuous supply of hot water on demand.

The benefits of tankless water heaters are numerous. One of the main advantages is energy efficiency. Traditional water heaters continuously heat and reheat water in the tank, even when it’s not being used. In contrast, tankless water heaters only heat the water when it is needed, resulting in significant energy savings. According to the U.S. Department of Energy, switching to a tankless water heater can save homeowners up to 30% on their energy bills.

Another advantage of tankless water heaters is their compact size.
