Tankless Water Heaters: Types, Maintenance, & Installation

As energy efficiency and environmental sustainability become increasingly important for homeowners, many people are considering alternative options to traditional, tank-based water heaters. In this article, we will explore the world of tankless water heaters. This innovative hot water solution offers numerous benefits in terms of utility cost savings, space optimization, and eco-friendliness. Drawing from our extensive experience and expertise at Genuine Plumbing & Rooter Inc., our aim is to provide insightful information on the types of tankless water heaters available, how they function, the benefits they offer, and their maintenance requirements, ultimately helping you determine whether a tankless water heater is the right choice for your home.

Tankless water heaters, also known as on-demand or instantaneous water heaters, heat water as needed rather than storing preheated water in a large tank. This innovative technology provides a continuous supply of hot water, increases energy efficiency, and eliminates the risk of running out of hot water during peak usage times. By switching to a tankless water heater, homeowners can enjoy energy and cost savings, as well as reduced environmental impact.

In the sections that follow, we will delve deeper into the advantages of tankless water heaters, discussing the various types available—such as electric and gas models—and the factors to consider when selecting the right unit for your home. Additionally, we will share essential maintenance tips to keep your tankless water heater functioning efficiently and provide a consistent hot water supply. Finally, we will explore the importance of professional installation and the role that the team at Genuine Plumbing & Rooter Inc. can play in ensuring a seamless transition to this innovative hot water solution.

Advantages of Tankless Water Heaters over Traditional Tank-Based Systems

The numerous benefits associated with tankless water heaters make them an increasingly popular choice for homeowners. Let’s delve into the various advantages they offer over traditional tank-based systems:

1. Energy Efficiency: Tankless water heaters only heat water on demand, making them more energy-efficient than storage tank systems that continuously heat and reheat water to maintain a constant temperature.

2. Lower Utility Bills: Improved energy efficiency can translate to lower utility bills, often resulting in substantial long-term savings for homeowners.

3. Continuous Hot Water Supply: With a tankless water heater, you’ll enjoy an uninterrupted supply of hot water, as it heats the water only when needed.

4. Space-saving: Tankless water heaters are more compact than their tank-based counterparts, allowing for installation in smaller spaces and offering more flexible placement options.

5. Longer Lifespan: With proper maintenance, tankless water heaters typically have a longer service life than traditional tank-based systems, often ranging from 15 to 20 years.

Choosing between Electric and Gas Tankless Water Heaters

There are two primary types of tankless water heaters: electric and gas. Selecting the right one for your home depends on several factors, including your specific hot water needs and energy preferences. Here’s an overview of the key differences between gas and electric units:

1. Fuel Source: Electric tankless water heaters rely on electricity to heat the water, while gas units use natural gas or propane.

2. Energy Efficiency: Although both varieties are more energy-efficient than traditional water heaters, electric models are generally considered to be more energy-efficient than their gas counterparts.

3. Installation Costs: Gas tankless water heaters often have higher upfront costs due to additional components required, such as venting systems, while electric units are typically cheaper and easier to install.

4. Size and Space Requirements: Gas models are usually larger than electric models, potentially affecting where they can be installed in your home.

5. Climate Considerations: Colder climates can impact the performance of electric tankless water heaters, while gas models tend to be less affected by external temperatures.

Consult with an experienced plumbing professional, like the team at Genuine Plumbing & Rooter Inc., to determine the most suitable tankless water heater for your home.

Maintaining Your Tankless Water Heater for Optimal Performance

To ensure the longevity and efficiency of your tankless water heater, regular maintenance is essential. Follow these tips to keep your unit functioning optimally:

1. Annual Inspections: Schedule a professional inspection of your tankless water heater at least once a year to check for any issues or potential maintenance needs.

2. Flushing: Periodically flush your tankless water heater (once every six months to two years, depending on usage) to prevent scale buildup that can affect the performance of the unit.

3. Clean the Filter: Clean or replace your water heater’s filter (if applicable) according to the manufacturer’s recommendations to maintain optimal water flow.

4. Vent Maintenance: For gas tankless water heaters, inspect and clean the venting system annually to ensure proper ventilation and prevent any safety hazards.

The Importance of Professional Installation for Tankless Water Heaters

Choosing a trustworthy and skilled plumbing professional for the installation of your tankless water heater is crucial to ensure a seamless transition, optimal performance, and long-term satisfaction. The benefits of professional installation include the following:

1. Proper Sizing: A professional plumber can accurately determine the size and capacity of the tankless water heater you need based on your property’s hot water demands.

2. Correct Venting: For gas tankless water heaters, a professional will ensure proper installation of the venting system, which is crucial for both performance and safety.

3. Electrical or Gas Line Adjustments: An experienced plumbing professional can make any necessary electrical or gas line adjustments to accommodate the new system.

4. Warranty and Support: Professional installation often comes with a warranty on labor, providing you with peace of mind and support if any issues arise.


Tankless water heaters offer numerous advantages, such as energy efficiency, lower utility costs, and a continuous hot water supply. By understanding the differences between electric and gas models, and the importance of proper maintenance and professional installation, homeowners can make an informed decision and enjoy the benefits of this innovative technology.
