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, holding onto an ample supply of water that’s continually heated. Whenever 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 in part to a straightforward design.
  • Easier Maintenance: A streamlined design also leads to fewer potential maintenance needs.


  • Continuous Energy Use: Tank water heaters have to keep water continuously heated, which equals extra cost if you’re not constantly using that water.
  • Space Requirements: The tank itself can be a challenge in tight quarters. If your home doesn’t have a basement or utility closet, installation becomes a bit trickier.

On-Demand Tankless Water Heaters: A More Modern Option

Now, let's check out tankless water heaters, an energy-efficient alternative that’s relatively modern. Distinct from tank models, tankless water heaters operate when needed. They’re heating up water only when needed, using robust heating elements as the water flows through the system.


  • Greater Energy Savings: Tankless models boast much higher energy efficiency since they aren’t constantly running.
  • Surprisingly Durable: With routine maintenance from a certified expert, tankless water heaters can enjoy many years of service.


  • Larger Initial Investment: Initial installation costs are higher as a result of the more sophisticated design.
  • More Frequent Maintenance: Tankless models do best when provided more routine attention to keep their key elements working efficiently.
  • Compatibility Issues with Old Plumbing: Older homes may not be ready for a tankless water heater. Plumbers can modify 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 greater energy efficiency that tankless water heaters are capable of. But this also depends on factors such as how much hot water you go through every day. You’ll want to reflect on your specific hot water needs before you make your selection.

  1. Your Average Hot Water Consumption: Assess how much hot water your household goes through on average. As an example, big families who are active in sports or have pets will need significantly more hot water than if you live by yourself.
  2. Space for Installation: The dimensions of your home can influence how well a water heater operates. Consider potential installation locations and confirm with professionals if your model is an appropriate size.
  3. Regional Climate: Harsh winters mean your water heater will need more energy. This isn’t ideal for tankless models, which are best suited when there won’t be any large fluctuations in water usage.
  4. Utility Costs: Your local utility rates can make one option more enticing over the other.

Don’t forget, a trained professional like those at Kohles & Bach Heating & Cooling can help you in making a more informed decision. They understand which makes and models meet your specific needs before delivering a smoother installation process.
