Storage Tank Water Heaters: A Time-Tested Favorite

Let's get to know conventional storage tank water heaters first. That sizable storage tank is the key feature here, ensuring you have an abundant supply of water that’s constantly heated. The moment you need hot water, a tank water heater is ready to supply it.


  • Lower Initial Costs: Tank water heaters typically have smaller expenses for installation, thanks in part to a straightforward design.
  • Simplified Upkeep: A streamlined design also means fewer potential maintenance needs.


  • Nonstop Heating: Tank water heaters must keep water perpetually heated, which equals extra cost if you’re not constantly using that water.
  • Bulky Size: The tank itself could become a challenge in cramped spaces. If the property lacks a basement or utility closet, installation becomes a bit trickier.

On-Demand Tankless Water Heaters: A More Modern Option

Now, let's consider tankless water heaters, an advanced alternative that’s comparatively recent. Compared to tank models, tankless water heaters operate on-demand. They’re heating up water only when you ask for it, thanks to efficient heating elements as the water passes through the system.


  • Greater Energy Savings: Tankless models can improve your plumbing’s energy efficiency since they’re not operating nonstop.
  • A Smart, Resilient Design: With regular maintenance from a certified expert, tankless water heaters can boast many years of service.


  • Higher Setup Cost: Initial installation costs are higher due to the more intricate design.
  • More Frequent Maintenance: Tankless models do best when provided more routine attention to keep their vital components functioning smoothly.
  • Potential Need to Update Plumbing Infrastructure Updates: Older homes aren't always prepared for a tankless water heater. Plumbers can adapt your plumbing to accommodate one, but it might complicate your installation project.

Picking Your Water Heater: Consider What Suits You Best

For a majority of homeowners, we’d recommend the higher energy efficiency that tankless water heaters are capable of. But this may be dependent on factors such as 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: Estimate how much hot water your household goes through on average. As an example, large families who enjoy sports or have pets almost always need much more hot water than if you live by yourself.
  2. Space for Installation: The size of your home can impact how effectively a water heater operates. Review potential installation locations and consult with professionals if your model is capable of fitting where you want it go.
  3. Regional Climate: Harsh winters mean your water heater will need more energy. This isn’t ideal for tankless models, which are most efficient when there won’t be any large fluctuations in water usage.
  4. Fuel and Electricity Rates: Your community’s energy prices can render one option more enticing over the other.

Remember, seasoned installers like those at Kohles & Bach Heating & Cooling can help you in making a more knowledgeable decision. They understand which brands meet your specific needs before ensuring a smoother installation process.
