Trying to choose between a classic water heater with a storage tank or a newer, tankless water heater is a decision you’ll probably face at some point. After all, water heaters are the gold standard for a reliable source of hot water. Because your plumbing fixtures and home appliances depend on this hot water, it’s always important to consider all your options carefully.

This handy guide from the local experts at B & G HVAC lays out tank and tankless water heaters. You’ll learn more about the differences in their design as well as some benefits and drawbacks of each kind. These key details will help you make an informed choice that meets your home's hot water needs. Once you’ve decided, keep us in mind for expert tank water heater installation.

Conventional Storage Tank Water Heaters: The Reliable Choice

Let's get to know conventional storage tank water heaters first. That ample storage tank is the central feature here, ensuring you have an ample supply of water that’s always heated. The moment you need hot water, a tank water heater can provide it.


  • Budget-Friendly Installation: Tank water heaters typically have smaller expenses for installation, thanks to their straightforward design.
  • Easier Maintenance: A streamlined design also translates into less potential maintenance needs.


  • Higher Energy Use: Tank water heaters must keep water perpetually heated, which equals extra cost if you’re not regularly using that water.
  • Large Overall Size: The tank itself could become a hurdle in tight quarters. If your home lacks a basement or utility closet, installation is a bit trickier.

Tankless Water Heaters: Cutting-Edge Comfort

Now, let's consider tankless water heaters, an energy-efficient alternative that’s providing more flexibility to homeowners. Unlike tank models, tankless water heaters operate on-demand. They’re generating hot water only when needed, thanks to efficient heating elements as the water flows through the system.


  • Greater Energy Savings: Tankless models are much more energy efficient since they’re not constantly running.
  • Surprisingly Durable: With regular maintenance from a trained technician, tankless water heaters can offer a longer life span.


  • Larger Initial Investment: Initial installation costs are higher because of the more intricate design.
  • More Frequent Maintenance: Tankless models will usually need more routine attention to keep their important parts working efficiently.
  • Compatibility Issues with Old Plumbing: Older homes aren’t always equipped for a tankless water heater. Plumbers can retrofit your plumbing to accommodate one, but it might complicate your installation project.

Choosing the Right Water Heater: Tailored to Your Comfort

For a majority of homeowners, we’d recommend the greater energy efficiency that tankless water heaters can offer. But this also depends on factors such as how much hot water you use each day. You should have a basic idea of how much water is needed to meet your specific hot water needs before you make your decision.

  1. Typical Hot Water Use: Estimate how much hot water your household consumes on average. For instance, larger families who are active in sports or have pets will need significantly more hot water than a single person living alone.
  2. How Much Space the Heater Itself Needs: The layout of your home can impact how effectively a water heater operates. Check out all possible installation locations and consult with professionals if your model is capable of fitting where you want it go.
  3. Regional Climate: Brutally cold winters mean much higher energy use that time of year. This isn’t ideal for tankless models, which are most efficient when there won’t be any big spikes in water usage.
  4. Fuel and Electricity Rates: Your average fuel or electricity costs can render one option more attractive over the other.

Keep in mind, seasoned installers like those at B & G HVAC can help you in making a more educated decision. They understand which brands meet your specific needs before delivering a smoother installation process.
