If you’re having trouble with the temperature of your water, you’re probably in the market for a new water heater. Water heaters come in tank and tankless options, which can both help improve the efficiency of your plumbing system.
Switching from a traditional tank water heater to a tankless model is a common upgrade for homeowners looking for better energy efficiency and long-term savings.
Tankless water heaters are one option that offers many benefits. If you’re wondering why you should upgrade to a tankless water heater, explore the following benefits and see if this option is right for your home.
A tankless water heater, also known as an instantaneous or on-demand water heater, is a device that only heats water as you need it. Unlike traditional tank water heaters that store water, tankless units heat water as it flows through it.
When you turn on the hot water at any faucet or fixture in your home, cold water will enter the tankless water heater. As the water passes through the unit, it is heated by either an electric element or a gas burner. A gas fired unit is a type of tankless water heater that uses a burner fueled by natural gas or propane to heat water on demand. Gas tankless water heaters, powered by natural gas or propane, are known for their energy efficiency and ability to provide continuous hot water. As water flows through the system, it passes through heat exchangers before reaching the faucet, ensuring a steady supply of hot water. The hot water is then delivered to the faucet.
Tankless water heaters, often called on-demand water heaters, operate by heating water only when you need it—eliminating the need for a bulky storage tank. When you turn on a hot water faucet, cold water travels through the tankless water heater, where it is rapidly heated by either an electric element or a gas burner. This process delivers a constant supply of hot water directly to your faucet, so you never have to wait for a tank to refill or continually heat water when it’s not in use.
Because tankless water heaters only heat water as it’s needed, they are much more energy efficient than traditional models. This means you can save energy and reduce your utility bills, all while enjoying hot water on demand. Whether you choose an electric or gas-powered tankless water heater, you’ll benefit from a system that heats water quickly and efficiently, providing the right amount of hot water whenever you need it.
You may consider upgrading to a tankless water heater if you are constantly running out of hot water, need to save space in your home’s utility room, or want to reduce your monthly energy bills. However, it’s important to assess your specific needs and budget first before determining if this is the right investment for you.
By carefully considering the following factors, you can determine if upgrading to a tankless water heater is the right choice for you.
One of the most compelling reasons to switch to a tankless water heater is the endless hot water supply it can provide.
Unlike traditional tank-style water heaters that have a limited capacity, tankless units heat water on demand. This means that you don’t have to wait for a tank to refill every time you need more warm water.
Whether you’re hosting a houseful of guests, tackling a big laundry day, or simply enjoying a long, luxurious bath, you’ll never run out of hot water again.
Tankless water heaters are known for being more energy efficient than traditional tank styles. Tank-style water heaters must constantly heat and reheat their tank of water to keep up with demand. Since tankless units only heat when hot water is necessary, energy consumption is significantly reduced, resulting in lower utility bills.
Additionally, tankless water heaters don’t experience heat loss through tank insulation, further enhancing their efficiency. Reducing energy consumption also means that these units can lower your carbon footprint by eliminating the risk of water leaks.
While tank-style water heaters take up a significant amount of space, tankless units are smaller and offer flexible installation options. This makes them ideal for homes with limited space, especially in utility areas like closets or basements.
Whether you want to mount the unit on a wall or install it in a closet, upgrading to a tankless water heater allows for seamless integration in your home.
Low water pressure is a common issue in many homes, especially when multiple fixtures or appliances are being used simultaneously. This is a common problem when homes have a tank-style water heater.
On the other hand, tankless water heaters deliver consistent water pressure, even if multiple faucets, showers, or appliances are in use. You can easily enjoy a refreshing shower or wash your laundry without fluctuations in water pressure.
Tankless water heaters are typically more durable than traditional tank-style ones. With proper water heater maintenance, tankless units can last a lot longer. This reduces the frequency of replacements and the associated costs that come with installing a new unit.
Water filtration systems are the main contributor to improved water quality, which can be incorporated with tankless water heaters for fresher, healthier water. Treating your water with a whole-home system is the best way to improve its taste and quality.
When deciding between tankless water heaters and traditional tank water heaters, it’s important to weigh the benefits and drawbacks of each system. Tankless water heaters stand out for their energy efficiency, as they only heat water when you need it, reducing energy waste and helping you save on utility bills. They also provide a constant supply of hot water, so you never have to worry about running out during a shower or while doing laundry. Plus, their compact design means they take up less space, making them a great fit for smaller homes or apartments.
However, tankless water heaters typically come with a higher upfront cost and often require professional installation to ensure optimal performance. Traditional tank water heaters, while generally less expensive to purchase and install, are less energy efficient because they continually heat and store water, which can lead to higher energy consumption and utility bills. They also take up more space and may not provide enough hot water for larger households with high demand. Ultimately, the choice between tankless and tank water heaters depends on your budget, space, and hot water needs.
While tankless water heaters offer numerous benefits, you’ll still want to consider a few factors before upgrading. This includes:
Upfront Costs: Tankless systems typically have a higher initial cost compared to traditional models. However, the long-term energy savings can offset this investment.
Water Flow Rate and Sizing: Tankless water heaters have a maximum flow rate. If you have multiple high-flow fixtures or a larger household, you might need a larger unit or install multiple tankless systems to meet your hot water demands. Proper sizing is essential for optimal performance.
Gas Line Requirements: Installing a gas tankless system may require upgrading the gas line or gas lines to meet higher BTU requirements. Professional expertise is needed to ensure safe and proper gas supply connections.
Water Usage: Understanding your household’s water usage is important to select the right tankless system and ensure it meets your hot water needs.
Professional Installation: Proper installation is crucial for optimal performance and safety. It’s recommended to hire a qualified plumber for the installation, especially when modifying gas lines.
Hard Water: Mineral buildup can affect the performance of tankless water heaters. If you have hard water, consider installing a water softener to protect your unit.
Maintenance: Tankless systems generally require less maintenance than traditional tanks, which need to be drained or have the water inside cooled for safety and maintenance purposes.
To keep your tankless water heater running efficiently and extend its lifespan, regular maintenance is essential. One of the most important tasks is preventing mineral buildup, which can reduce the efficiency of your tankless water heater and even shorten its life. Performing a vinegar flush every 500 hours of use helps dissolve mineral deposits and keeps your system operating smoothly. It’s also important to check and clean the unit’s filters regularly to maintain proper water flow and ensure you always have enough hot water.
If you notice a drop in hot water flow or a spike in your energy bills, it could be a sign that your tankless water heater needs repair. Addressing issues promptly with the help of a professional can prevent more serious problems and costly repairs down the line. With proper maintenance and timely repairs, your tankless water heater will continue to deliver energy efficient, reliable hot water for years to come.
Consulting with a plumbing professional is the best way to determine whether it’s time to upgrade to a tankless water heater. A plumber can help you make the most informed decision based on your home’s hot water needs.
