Storage Tank Water Heaters: A Time-Tested Favorite

Let's examine conventional storage tank water heaters first. That sizable storage tank is the central feature here, holding onto an ample supply of water that’s continually heated. As soon as you need hot water, a tank water heater can provide it.


  • Lower Initial Costs: Tank water heaters generally have lower up-front installation costs, thanks to their straightforward design.
  • Simplified Upkeep: A streamlined design also means fewer potential maintenance needs.


  • Continuous Energy Use: Tank water heaters must keep water continuously heated, which means extra cost if you’re not frequently using that water.
  • Large Overall Size: The tank itself can be a problem in smaller spaces. If your home lacks a basement or utility closet, installation can be a bit trickier.

On-Demand Tankless Water Heaters: A More Modern Option

Now, let's consider tankless water heaters, an innovative alternative that’s providing more flexibility to homeowners. Distinct from 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.


  • Less Energy Used: Tankless models can improve your plumbing’s energy efficiency since they aren’t operating nonstop.
  • Surprisingly Durable: With regular maintenance from a trained technician, tankless water heaters can enjoy many years of service.


  • Larger Initial Investment: Initial installation costs are higher because of the more sophisticated design.
  • May Need More Upkeep: Tankless models will usually need more regular servicing to keep their important parts in sync.
  • Retrofitting Challenges: Older homes aren't always prepared for a tankless water heater. Plumbers can modify your plumbing to accommodate one, but it could add further costs to your installation project.

Deciding on Your Ideal Water Heater: Every Home Has Unique Needs

In general, we’d suggest the greater energy efficiency that tankless water heaters are capable of. But this is based on aspects including how much hot water you use each day. You should think about your specific hot water needs before you make your selection.

  1. Your Home’s Usual Hot Water Requirements: Gauge how much hot water your household goes through on average. As an example, big families who are active in sports or have pets usually need significantly more hot water than a single person living alone.
  2. Space for Installation: The layout of your home can affect how effectively a water heater operates. Consider potential installation locations and consult with professionals if your model is an appropriate size.
  3. The Area’s Average Temperatures Through the Year: Long winters mean a water heater that works harder. This reduces the efficiency of tankless models, which are better in situations when there won’t be any big spikes in water usage.
  4. Fuel and Electricity Rates: Your local fuel or electricity costs can render one option more appealing over the other.

Remember, seasoned installers like those at AZ Air Conditioning and Heating can assist you in making a more informed decision. They understand which makes and models meet your specific needs before delivering a smoother installation process.
