  • Tankless Water Heater Installation Gwinnett | All You Need To Know

    The tankless water heater installation Gwinnett residents want is affordable. But how much does it cost to go tankless in Lawrenceville, Buford, or Norcross? Contact us for a quote for tankless water heater installation. Keep reading to learn about the costs, the benefits, and more.

    Tankless water heaters, or demand-type or instant water heaters, only provide hot water when needed. As the name suggests, they do not have a tank that constantly keeps multiple gallons of water hot. Instead, they quickly heat water when you turn the faucet on, providing a constant stream of hot water. However, not all tankless water heating systems can supply enough hot water for several faucets and showers simultaneously. But suppose you install the right size and number of tankless water heaters. In that case, you can genuinely have endless hot water.

    How Much Does Tankless Water Heater Installation Cost in Gwinnett?

    tankless-water-heater-installation-gwinnettHere is a guide to learn all you need to know about tankless water heater installation costs in Gwinnett. The cost of a tankless water heater installation hinges on several factors.

    Factors To Consider:

    Most homeowners pay around $3,000 for a tankless water heater installation. However, costs may dip to around $1,000 or rise as high as $5,500 based on factors specific to your installation situation.

     1. Tankless Water Heater Cost Based on Size

    Tankless water heaters vary in price depending on size. And size is a function of the flow rate measured in gallons per minute or GPM. Tankless water heaters vary in cost depending on whether they are a point-of-use available for $150 – $500 or whole-home unit for $500 – $2,000. Units can cost as low as $150 for a 1–2 GPM unit and over $900 for an 8-plus GPM unit.

    2. Fuel Type And Tankless Hot Water Heater Prices

    Tankless water heaters are popular for homeowners who want an energy-efficient, space-saving alternative to traditional tank-style water heaters. Different power sources for tankless water heaters are available, each with advantages and disadvantages. Please keep reading to learn more about electric, natural gas, oil, propane, solar, and tankless water heaters and how they compare.


    An electric tankless water heater is the easiest to install and maintain, making it the most popular option. It is also one of the more affordable options, making it an excellent choice for budget-conscious homeowners. Electric water heaters typically cost between $500 and $1,000.

    They are readily available in the most petite sizes. So, electric tankless units are ideal for a two-person household living in a tiny house or somewhere with limited space. However, electric tankless water heaters are generally a poor choice for supplying enough hot water for a four-person household.

    Natural Gas:

    Natural gas-powered on-demand water heaters are generally more expensive than other options. So, the equipment costs more, and on top of that, installation is more complex. It will involve gas lines and connections that require more labor, increasing the overall installation cost.

    So, natural gas instant water heaters cost more than electric units. However, gas units are not only energy efficient but also can supply high water demand households. They are an intelligent choice for homes with four or more people. Natural gas water heaters range from $750 to $2,000.


    Some tankless water heaters heat water using oil and electricity. In these highly efficient units, a burner with an electric spark ignition lights an oil and water mixture to heat water. Oil water heaters typically range in cost from $1,000 to $3,000. The ignition and heating process allows these water heaters to provide quick heating times. They are suitable for homes with high water demand.


    Propane tankless water heaters supply on-demand hot water using propane exclusively. However, you will find some natural gas units that can run on propane by installing a converter. Converting a natural gas water heater to run on propane adds to the total cost of installation. On average, propane water heaters cost $500 to $2,000. These models are prevalent in rural areas where natural gas lines are unavailable, and propane tanks are commonplace.


    Solar, tankless water heaters provide an eco-friendly water heating system. These units have low operating costs since they are sun-powered. However, these cost the most to install and maintain. As the most expensive option, upfront costs range from $1,500 to $4,000. However, a solar unit provides the most cost savings of all the options over time. It will begin paying for itself immediately in energy savings.

    The cost of a tankless water heater varies based on the type of fuel powering it. The average cost for a tankless water heater in various fuel types follows. An electric unit costs $500 to $1,500. Natural gas models range from $750 to $2,000. Oil-fueled on-demand heaters cost from $1,000 to $3,000. And Propane-powered units cost from $500 to $2,000. Solar, tankless hot water heaters are the most expensive on the front end at $1,500 to $4,000 per unit.

    3. Brand Name and Average Tankless Water Heater Price

    The brand name of your tankless water heater can significantly impact the final cost of installation. While some brands offer more affordable products, others, especially well-known brands, come with higher price tags. As the cost of the water heater is part of the installation price, the brand plays a crucial role in determining the total cost. It is essential to note that while tankless water heaters take up less space than traditional tank units, they may have a lower capacity, so consider this factor when searching for a unit.

    There are a handful of tankless water heater manufacturers with brand names most people find familiar. It is not worth it to purchase a substandard water heater from an unproven company to save a moderate amount. The best plan is to consult with a water heater expert like us to help you choose a quality heater that meets your needs for the best price.

    4. Water Heater Installation Labor Costs In Gwinnett County

    Tankless water heaters are popular for Gwinett area homeowners due to their energy efficiency, space-saving design, and longer lifespan. However, the cost of installing a tankless water heater depends on factors other than the ones mentioned previously: size, brand, and fuel type. The total cost includes the appliance, materials for installation, labor, and necessary home structural changes.

    The labor portion significantly contributes to the total costs of installing a tankless water heating system. Labor costs vary based on the complexity of the job. Nearly every aspect of installation influences the level of difficulty of the project. It directly relates to how much labor will cost you.

    For instance, electric units are a breeze for a professional plumber to install. Solar units are the most challenging and time-consuming to install at the other end of the spectrum, requiring a highly skilled plumber. So, naturally, solar installation labor takes longer and costs more due to the complexity of the task.

    We can estimate labor costs for installing tankless water heaters powered by different fuel sources. Regarding the electric versus solar comparison, Electric labor can range from $150  to $1,000. On the other hand, solar labor falls in the $1800 to $4000 range—natural gas and propane installation costs for labor in Gwinnett range from around $900 to $1500.

    5. More Factors That Add To Tankless Water Heater Installation Cost

    When estimating the total cost of installing a tankless water heater, it is essential to consider all the factors influencing total cost to avoid surprises. We discuss five factors.

    1. Required Parts and Materials

    When installing a tankless water heater, various parts and materials are necessary, depending on the type of heater you choose. For instance, gas water heaters need special gas connectors and must vent gas exhaust. These requirements add to the cost of labor and materials to install a gas-powered tankless heater.

    Apart from the necessary parts, you will also incur costs for mounting brackets, fittings, valve sets, piping, insulation, and other miscellaneous materials. Installation of new piping and insulation is a function of the length of pipe required. The other items typically are under $200.

    1. Condensing versus Non-Condensing

    You should know that tankless water heaters can be condensing or non-condensing. Condensing models offer better energy savings by capturing and using exhaust heat in a secondary heat exchanger. However, they tend to be more expensive. On the other hand, non-condensing tankless water heaters use a single heat exchanger. They are about 17% less efficient than their condensing counterparts but have lower upfront costs to manage.

    1. Renovation and Retrofitting Requirements

    The total cost will reflect if the new tankless system requires significant electrical or structural changes to your home. The exact amount you will pay is highly variable, depending on the difficulty of the project and the type of retrofitting or renovations that are necessary.

    1. Uninstallation and Disposal of Old Tank Water Heater

    Suppose you have an old heater that needs replacing, such as a tank-style water heater. In that case, you will incur costs to uninstall, remove, and dispose of it. Tasks include disconnecting and draining the old unit, safely removing the heater from your home, and safely disposing of it at a local area waste facility.

    The accessibility and size of the system will determine how expensive this part of the project will be. The average cost to remove an old water heater setup is around $500, taking over an hour. Ensuring that the quote includes removing and disposing of the old system is essential for accurately estimating the total expense of installation.

    Tankless Water Heater Benefits

    Tankless water heaters are superior to traditional tank-style water heaters in many ways. If you are considering getting a tankless water heater for your home, here are some benefits to keep in mind that may help you decide.

    1. Save on Energy Bills

    Tankless water heaters are highly energy efficient, which makes them a cost-effective way to heat water for your home. Unlike tank-style water heaters that constantly heat and reheat water stored in the tank, tankless units deliver on-demand hot water to your faucets, significantly reducing energy usage. As a result, you can save up to 50% on energy costs compared to a tank-style water heater.

    1. Never Run Out of Hot Water

    Tankless water heaters provide endless hot water, ensuring you always have hot water when needed. They produce hot water on demand, so you do not have to worry about running out of it, even if multiple people use it simultaneously.

    1. Take Advantage of Tax Credits

    Tankless water heaters are eligible for various tax credits due to their energy-efficient design. These tax credits help reduce your tax bill and minimize your debts during the next tax season.

    1. Save Space in Your Utility Room

    Tank water heaters are typically large and can take up a lot of space in your garage or utility room. Switching to a tankless water heater frees up this space for other purposes. The space-saving aspect is especially beneficial when space is hard to come by.

    1. Longer Lifespan

    Tankless water heaters typically last much longer than tank-style water heaters, so you will not have to replace them as frequently. So, you save money eventually since water heaters are expensive. Suppose you want a more energy-efficient, space-saving, and longer-lasting water heating solution. In that case, a tankless water heater is worth considering.

    Tankless Water Heater Installation: Should You DIY or Hire a Professional?

    You might consider doing it yourself when installing a tankless water heater to save money. However, this is not a good idea. DIY installation is risky for you and your plumbing system. Do not attempt the project yourself unless you have the knowledge, tools, and experience. Hiring a professional is best.

    DIY Installation

    If you are an experienced DIYer, that does not mean you can handle a tankless water heater installation. Please leave it to the professional plumbers. Improper installation can be dangerous, resulting in explosions or carbon monoxide poisoning. If you are not sure what you are doing, hire a professional.

    Professional Installation

    Hiring a pro plumber for your tankless hot water heater installation is the safest and most reliable option. You can count on correct installation, and the unit will function properly for years. You usually get the best warranty coverage when a professional installs your system. Moreover, DIY tankless installations often void equipment warranties.

    How to Choose a Professional

    To find a professional to install your tankless water heater:

    1. Start by researching local experts.

    2. Ask co-workers, neighbors, friends, and family for recommendations, and get quotes from a few providers.

    3. Compare the plumbers to find the best option, then schedule an installation date with your chosen provider.
