Tank vs. Tankless | Which Water Heater is Best For You?

Buzzell • April 22, 2025

While owning your home has a host of benefits, it also has its downsides. One of them being the fact that homeowners have to make tough decisions on big purchases. One common purchase for homeowners is deciding what kind of water heater they’ll need once it’s time for a replacement. It can be a daunting task, because buying a water heater is not only an expensive purchase, but a commitment as well.


Water heaters can last well into a decade, with some even lasting 20 years. So, it’s not a decision that’s taken lightly. Let us help you determine which one’s the best option by breaking down the two main types: tank and tankless water heaters. By evaluating their pros and cons, you’ll have a better idea of which is right for your home. 


Tank Vs. Tankless water heaters | A comparison


Tank Water Heaters


Pros: 

  • Less expensive –  Tank heaters have a relatively straightforward design, which makes them easier to install, especially in older homes with older plumbing and electrical. Because they are easier to install, less labor is required, making their initial installation cheaper than tankless water heaters.


Cons: 

  • Limited heater water – Because the tanks can only hold a certain amount of water, homeowners can run out of hot water. This may be a problem for larger families, especially if your tank isn’t big enough to accommodate the amount of water being used in the home.
  • Requires more space – Traditional tank water heaters take up more space because they need to store a large volume of heated water, typically between 30 to 80 gallons. This makes them less ideal for smaller homes, apartments or utility rooms where floor space is limited. 
  • Shorter lifespan than tankless Tank water heaters typically last between 6 to 13 years, depending on usage and maintenance. This is significantly shorter than tankless models, which can often last 20 years or more. For homeowners looking for a longer-lasting investment, a tankless system may offer better long-term value despite the higher upfront cost.


Tankless Water Heaters


Pros: 

  • Unlimited heated water – Because they don’t have tanks, tankless water heaters can produce an unlimited amount of water. This may be better for large families who tend to use more hot water for showers and cleaning. 
  • Energy efficient – Tankless water heaters are more energy efficient, which means they use less water than tank heaters. This is not only more environmentally friendly, but it saves homeowners on monthly utility bills.
  • Requires less space – Tankless water heaters require less space, making them easier to store in your smaller homes, apartments and closets.
  • Longer lifespan – Tankless heaters last 15 to 20 years, which is several years longer than tank water heaters.


Cons: 

More expensive – Because tankless water heaters are more complex in their design, they take longer to install. With higher labor costs, the overall installation is more expensive than it would be if it was a tank heater. 


So, what’s the best option for homeowners? 


While tankless water heaters offer plenty of advantages, they’re not always the perfect fit for every home. Although they typically come with more benefits than traditional tank models (like improved energy efficiency and endless hot water) the right choice ultimately depends on your household’s needs, lifestyle and budget.

If you're working with a tighter budget or have lower daily hot water demands, a traditional tank water heater might be the smarter, more cost-effective option. However, if you have more flexibility and are looking to lower your long-term utility costs, a tankless may be the better option for you.

Choosing the right system to heat your home is crucial for both comfort and energy efficiency, especially in Central Georgia. While the winters are not harsh, they can be damp and chilly. Two of the most common heating options for homeowners are heat pumps and furnaces. While both are deigned to keep your home warm in colder months, they operate in different ways. Because of this, heat pumps and furnaces come with their own set of pros and cons.
By Buzell March 6, 2025
Although we don’t see extremely low temps often here in Central Georgia, when the temperatures do drop, your furnace becomes one of the most important appliances in your home. A properly functioning heating system ensures that you stay warm and comfortable during the cold months of winter. However, like any mechanical system, furnaces experience wear and tear over time – and if you don’t know what to look out for, you could be left with a complete system failure when you need it most. If you notice any of the following signs, it may be time to schedule immediate furnace repair to prevent further damage and ensure your home stays warm and safe. Call Buzzell Plumbing, Heating & Air Conditioning today for a furnace inspection to keep your home warm for the rest of winter! 1. Strange Noises Coming from Your Furnace A furnace typically makes some noise as it operates, but loud, unusual sounds can indicate a serious problem. If you hear any of the following, it’s time to call a professional: Banging or booming – This could indicate a delayed ignition , where gas builds up before igniting, causing a mini explosion in your furnace. This can crack the heat exchanger and lead to carbon monoxide leaks. Squealing or screeching – A high-pitched noise may indicate a worn-out blower belt or issues with the motor bearings. Rattling or vibrating – Loose parts or ductwork issues could be the cause. Clicking – A continuous clicking sound could mean a failing ignition system or a faulty flame sensor . Ignoring these noises can lead to major furnace damage or even a breakdown. If your furnace sounds different than usual, don’t wait— call us today and schedule an inspection immediately. 2. Weak or No Airflow from Vents Our furnace should distribute warm air evenly throughout your home. If you notice weak airflow or cold spots, your furnace may have one of these problems: Clogged air filters – Dirty air filters block airflow, forcing your system to work harder and reducing heating efficiency. Replace filters every one to three months. Blower motor issues – If the blower motor is failing, it won’t push air through the ducts effectively. Blocked or leaky ductwork – Holes, leaks, or blockages in the duct system can prevent warm air from reaching every room. Failing fan or belt – If the fan or belt driving airflow is damaged, it needs repair or replacement. If your furnace is running, but your home still feels cold, it’s time to have an HVAC technician inspect and diagnose the problem. 3. Frequent Cycling (Turning On and Off Too Often) A properly functioning furnace should run in cycles, heating your home to the appropriate temperature and then shutting off. If your furnace turns on and off frequently (also known as short cycling ) this could be a sign of: Overheating – A dirty air filter, blocked vents, or malfunctioning components can cause the system to overheat and shut down prematurely. Thermostat issues – A faulty thermostat may misread temperatures, causing the system to turn on and off unpredictably. Improper furnace size – If your furnace is too large for your home, it will heat the space too quickly and shut off before completing a full cycle. Flame sensor problems – If the flame sensor is dirty or failing, it may shut off the burner too soon. Short cycling leads to higher energy bills, increased wear and tear and uneven heating . If your furnace isn’t running in proper cycles, it will save you money to have it repaired! Call us today to schedule an inspection if your furnace is short cycling. 4. Unusual or Burning Smells If your furnace produces any strong or lingering odors, it may be a sign that an urgent repair is needed: Burning dust smell – If you smell burning dust the first time you turn on your furnace for the season, this is usually normal and should disappear quickly. However, if the smell lingers, it could indicate dirty components or an overheating motor . Rotten egg or sulfur smell – This is a sign of a gas leak , which is extremely dangerous. Turn off your furnace immediately, evacuate your home, and call your gas company and Buzzell Plumbing, Heating & Air Conditioning . Electrical or burning plastic smell – This could indicate wiring issues, overheating components or a failing blower motor . Shut off your system and call for a repair. Musty or moldy smell – If your furnace smells damp or moldy, moisture could be trapped in the ducts, leading to mold growth and poor indoor air quality . If your furnace is producing any unusual smells, it’s best to have it inspected by a professional before it becomes a serious problem. 5. High Energy Bills Without Explanation If your energy bills are rising unexpectedly—even though your heating habits haven’t changed—your furnace might be losing efficiency. Some possible causes include: Clogged air filters – Restricted airflow forces your furnace to work harder, consuming more energy. Aging system – If your furnace is over 15 years old , it may no longer operate at peak efficiency. Malfunctioning components – A faulty thermostat, leaky ductwork, or a failing motor can cause your furnace to work overtime. Short cycling – If your furnace turns on and off frequently, it uses more energy than necessary. Ignoring these signs can lead to higher heating costs and potential system failure . Scheduling routine maintenance and addressing repairs promptly can help reduce energy waste and save you money. When to Call Buzzell Plumbing, Heating & Air Conditioning If you notice any of these warning signs, don’t wait until your furnace breaks down completely. Prompt repairs can prevent costly damage, dangerous carbon monoxide leaks and uncomfortable winter nights . Call us if you experience: Unusual noises (banging, screeching, rattling) Weak or inconsistent airflow Frequent cycling (turning on and off too often) Strange or burning odors Unexpectedly high energy bills Regular furnace maintenance can help catch minor issues early , extending the lifespan of your system and keeping it running efficiently.
