Ditch the Tank – Six Reasons to Switch to a Tankless Water Heater

Home | Blog | Published on September 24th, 2021

As anyone who has ever gotten the last shower in can tell you, when the hot water runs out, it can be pretty miserable. Having a professional tankless water heater company in Mt. Pleasant, SC, replace your old water heater and install a new water heater involves steps such as choosing the right location, measuring space, and installing new water lines and copper pipes for proper setup and safety. Replacing your old unit may involve installing new water lines and connecting pipes, including isolation valves and sediment traps, to ensure proper operation and prevent leaks. A hot water heater traditionally holds water and heats it continually until you are ready to use it. A tankless water heater works by instantly heating water to deliver it fresh and piping-hot, which means that you never run out! These are some other benefits of tankless water heaters. In gas models, a gas burner rapidly heats the water through a heat exchanger, providing a continuous hot water supply. When a hot water faucet is turned on, cold water enters the unit and is rapidly heated to the desired temperature before being delivered through your pipes, which distribute the hot water throughout your home. Tankless water heaters can be powered by gas, propane, or electricity, offering flexibility to suit different household needs. These are some other advantages to switching from a tank to a tankless model.

What are the benefits of tankless water heater installation?

  • Delivers hot water on demand with no waiting time
  • Reduces energy costs by heating water only when needed
  • Saves space with compact, wall-mounted units
  • Provides longer system lifespan than traditional tanks
  • Minimizes risk of leaks and water damage
  • Lowers environmental impact through efficiency and durability

Introduction to Tankless Water Heaters

Tankless water heaters, often called on-demand water heaters, are revolutionizing the way homeowners enjoy hot water. Unlike traditional water heaters that store and continually heat a large tank of water, a tankless water heater heats water only when you need it. This means you get heated water instantly, without ever worrying about running out. Tankless water heaters come in a variety of models, including tankless gas water heaters and electric tankless water heaters, each offering unique benefits to fit your home’s needs. When selecting a unit, it’s important to measure your household’s heated water demand to ensure you choose the right size and capacity for optimal performance and efficiency. Whether you’re looking to replace your old water heater or install a new gas tankless water heater or electric tankless water heater, these systems provide energy savings, space efficiency, and the convenience of endless heated water. Making the switch to a tankless water heater is a smart investment for any homeowner seeking comfort, efficiency, and long-term benefits.

Pre-Installation Considerations

Before you install a tankless water heater, it’s important to plan carefully to ensure the best results. Start by determining the appropriate size and capacity of the tankless water heater for your household. Measure the installation space and your hot water requirements to ensure the unit will fit and meet your needs. Consider how many bathrooms you have, how many appliances use heated water, and when your peak usage times are. This will help you select a unit that meets your needs without over- or under-sizing. Additionally, the flow rate, which is the maximum volume of hot water a tankless water heater can supply to meet demand, is a critical factor to consider when choosing the right unit.

Next, choose an installation location that offers easy access to water and gas lines, and make sure there’s proper ventilation if you’re installing a gas model. After selecting the location, check the incoming water pressure and consider installing a pressure reducing valve if necessary to ensure optimal performance and safety. The installation location should also comply with local building codes and safety regulations. It is crucial to comply with both local and national codes during the installation of a tankless water heater to ensure safety and proper operation.

If you are installing an electric tankless water heater, ensure proper wiring and circuit breaker sizing to maintain safety and optimal performance. Electric tankless water heaters require a dedicated high-voltage electrical circuit and may necessitate an electrical panel upgrade. Additionally, a plumbing, mechanical, and/or gas permit is required from the City of Charleston to install a tankless water heater. For the safest and most efficient water heater installation, it’s wise to hire a professional who specializes in tankless water heater installations. Careful attention to these details will ensure your new tankless water heater delivers reliable heated water for years to come. You should also read the product manual thoroughly before installation to familiarize yourself with the specific requirements and recommendations for your unit.

Professional Installation Requirements

Installing a tankless water heater is a job that demands careful attention to detail and a thorough understanding of plumbing and gas systems. Professional installation is highly recommended to ensure your tankless water heater is set up safely and efficiently. A licensed plumber with experience in tankless water heater installation will make sure the unit is properly connected to your home’s water and gas lines, and that all safety features, such as a pressure relief valve and sediment trap, are correctly installed. Some insurance providers may not cover damage from a DIY-installed tankless water heater unless installed by a licensed professional. Certain manufacturers may also void warranties if their water heaters are not installed by licensed contractors. This not only protects your home from potential leaks or gas issues but also ensures the system delivers heated water reliably. A professional can also help you determine the appropriate size and type of tankless water heater for your household, taking into account your hot water needs and the layout of your plumbing. By trusting a professional with your water heater installation, you can be confident that your new unit will be installed to code, operate safely, and provide years of efficient service.

Local Regulations and Codes for Installation

Before installing a tankless water heater, it’s crucial to be aware of the local regulations and building codes that govern water heater installations. These rules are in place to ensure safe operation and to prevent hazards such as gas leaks or improper venting. For example, many areas require that tankless water heaters be installed in a specific location with adequate ventilation and a properly installed exhaust vent, especially for gas models. Electrical connections and gas lines must also meet local standards to avoid safety risks. Failing to comply with these regulations can result in unsafe conditions and may even void your warranty or insurance coverage. A professional installer will be familiar with the local codes and will ensure your tankless water heater is installed in the right location, with all necessary safety measures in place, so you can enjoy peace of mind and reliable hot water.

New Unit Installation Process

The process of installing a new tankless water heater begins with preparing the installation location and disconnecting the old unit. First, the water and gas supply to the old water heater are shut off, and the old unit is carefully removed from the existing water and gas lines. The new tankless water heater is then mounted on the wall or in the chosen spot, ensuring it has proper access to both water supply lines and gas supply lines. Next, the installer connects the water and gas lines to the new unit, making sure all connections are secure and leak-free. For gas models, an exhaust vent is installed to safely direct combustion gases outside. Once everything is in place, the water and gas supply lines are turned back on, and the system is thoroughly tested for leaks and proper operation. You should test heated water at various fixtures after installation to ensure consistent performance. Following the manufacturer’s instructions during installation is essential for safe and efficient performance, ensuring your new tankless water heater delivers heated water whenever you need it.

Eco-Friendly

It is our duty to limit our carbon footprint for the next generations. A tankless water heater doesn’t have water sitting waiting while being heated. That means that you aren’t using energy around the clock. With a tankless system, you only heat the water when you need it. Also, thanks to the design, when it is time to replace your tankless system, it won’t end up in a landfill like tank systems. When installing a new system, it’s important to purge air from the water pipes to ensure efficient operation and prevent airlock issues. After purging, turn on the water supply to test for leaks and ensure the system is functioning properly. You should also insulate the heated water pipes after installation to improve energy efficiency and reduce heat loss. The average lifespan of a tankless water heater is 20 years or more, which is about twice as long as a conventional model.

Energy- and Cost-Efficient

By switching to a tankless water heater, you can save as much as 60% on your heating expenses, which is a huge cost savings! It might be more expensive to invest in than a tank water heater, but it will certainly pay off in the long run.

Safer to Use

Traditionally, tank water heaters have a storage tank that retains the heated water until you use it. That means the tank can rust and contaminate the water you use for bathing and drinking. Tankless water heaters deliver fresh rust-free water to your faucets; when you turn on a faucet, the tankless water heater detects the water flow and instantly activates to heat the water as it passes through the system. Tankless water heaters may use less fuel than conventional water heaters depending on usage, making them a more energy-efficient option. You also don’t have to worry about a tankless water heater rusting through and flooding your basement or developing a slow leak that can lead to water and mold issues.

Durable

A tankless water heater will last considerably longer than a tank water heater because they are made from extremely durable materials. Additionally, the price of tankless water heaters is decreasing due to innovation and increased installation familiarity among plumbers, making them a more accessible option for homeowners.

Endless Hot Water

One of the biggest advantages is that they supply an endless amount of heated water. Tankless water heater units work by taking cold water as it enters the system and rapidly heating it to provide a continuous supply of hot water. Unlike tank water heaters, there is no limit to how many gallons your home or family can use in a time period. If you have a large family, that is a great option!

Compact

A tank water heater can take up a significant amount of space. A tankless water heater is installed on the wall and takes up very little space. When selecting the chosen spot for your tankless water heater, it’s important to ensure proper ventilation and accessibility for maintenance. It can also be mounted indoors or outdoors, so you don’t have to find a place to put it, it can go pretty much anywhere! For gas models, installing an exhaust vent and properly connecting the vent are crucial steps to ensure safe operation and compliance with safety standards. During installation, it is also essential to inspect and verify or upgrade your gas line as necessary to ensure the system operates safely and efficiently. After installation, make sure to turn on the power to the unit and test its operation to confirm everything is working correctly.

Increased Home Value with Modern Plumbing

Upgrading to a tankless water heater is not just about comfort and efficiency—it can also boost your home’s value. Tankless water heaters are a sought-after feature for modern homes, offering a constant supply of hot water, improved energy efficiency, and a sleek, space-saving design. Potential buyers often see tankless water heaters as a sign of a well-maintained, up-to-date plumbing system, which can make your property more attractive on the market. In addition to the convenience and luxury of endless hot water, a tankless water heater reduces the risk of leaks and water damage, enhancing the overall safety of your home. By investing in a tankless water heater, you’re not only enjoying immediate benefits but also increasing the long-term value and appeal of your property.

Heater Installation Costs

When considering a tankless water heater, many homeowners are pleasantly surprised to learn that installation costs can be quite competitive with traditional tank water heaters. The total cost of installing a tankless water heater depends on several factors, including the type and model of the unit, the chosen installation location, and local labor rates. For example, non-condensing tankless water heaters can often be purchased for the same price or even less than a standard tank water heater. Condensing tankless heaters, while more expensive upfront, are more efficient and can provide greater energy savings over time. Additionally, a skilled plumber can typically install a tankless water heater in about the same amount of time as a traditional unit, which helps keep labor costs in check. When budgeting for your new tankless water heater, be sure to factor in the cost of the unit itself, any necessary installation materials such as copper pipe and isolation valves, and professional labor. By understanding these costs upfront, you can make an informed decision and enjoy the long-term savings that come with tankless water heaters.

Common Mistakes to Avoid During Installation

When installing a tankless water heater, avoiding common mistakes is key to ensuring safe and efficient operation. One frequent error is choosing a unit that’s too small for your household’s heated water needs, which can result in inconsistent water temperature and poor performance. Another mistake is improper venting, especially for gas models, which can lead to dangerous carbon monoxide buildup. Failing to connect the water and gas lines correctly or neglecting to check for leaks can cause serious safety hazards and system malfunctions. Skipping regular maintenance, such as flushing the system to remove mineral buildup and sediment, can reduce energy efficiency and shorten the lifespan of your unit. Always follow the manufacturer’s instructions, test the system thoroughly after installation, and schedule routine maintenance to keep your tankless water heater running smoothly. By steering clear of these pitfalls, you’ll enjoy reliable heated water and peace of mind for years to come.

Maintenance and Repair

To keep your tankless water heater running smoothly and efficiently, regular maintenance is essential. Schedule annual maintenance checks to inspect for leaks, flush the system to remove mineral buildup and sediment, and ensure all gas or electrical connections are secure. Testing your tankless water heater periodically helps guarantee safe operation and a steady supply of heated water. If you notice any issues, such as inconsistent water temperature or leaks, consult your owner’s manual or contact a professional for repairs. Proper maintenance not only protects your tankless water heater from unexpected breakdowns but also extends its lifespan and maintains its energy efficiency. By staying proactive with maintenance, you’ll enjoy reliable heated water and peace of mind for years to come.

Warranty and Support

When investing in a tankless water heater, it’s important to choose a model backed by a strong warranty and reliable customer support. Look for a manufacturer that offers comprehensive warranty coverage, including both parts and labor, to protect your system against unexpected issues. In addition, check if the manufacturer provides accessible customer support, such as online resources, phone assistance, and in-person service options. A solid warranty and support program ensures that you can quickly resolve any problems and keep your tankless water heater operating at its best. By selecting a reputable brand with excellent warranty and support, you’ll safeguard your investment and enjoy a worry-free experience with your new tankless water heater.
