Traditional Storage Tank Water Heaters: Tried and True

Let's get to know conventional storage tank water heaters first. That ample storage tank is the key feature here, holding onto an ample supply of water that’s always heated. Whenever you need hot water, a tank water heater can provide it.


  • Lower Initial Costs: Tank water heaters typically have lower up-front installation costs, thanks in part to a simpler design.
  • Streamlined Maintenance Needs: A streamlined design also translates into less potential maintenance needs.


  • Higher Energy Use: Tank water heaters have to keep water perpetually heated, which inevitably leads to extra cost if you’re not constantly using that water.
  • Bulky Size: The tank itself is sometimes a challenge in cramped spaces. If your home is missing a basement or utility closet, installation becomes a bit trickier.

On-Demand Tankless Water Heaters: A More Modern Option

Now, let's explore tankless water heaters, an innovative alternative that’s comparatively recent. Unlike tank models, tankless water heaters operate only as required. They’re heating only when you ask for it, thanks to efficient heating elements as the water flows through the system.


  • Greater Energy Savings: Tankless models can improve your plumbing’s energy efficiency since they aren’t operating nonstop.
  • Longer Life Span: With proper maintenance from a certified expert, tankless water heaters can offer a longer life span.


  • Higher Setup Cost: Initial installation costs are higher as a result of the more complex design.
  • Higher Service Needs: Tankless models may require more routine attention to keep their important parts in sync.
  • Retrofitting Challenges: Older homes may not be ready for a tankless water heater. Plumbers can adapt 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 suggest the greater energy efficiency that tankless water heaters are capable of. But this may be dependent on variables like how much hot water you use each day. You’ll want to have a basic idea of how much water is needed to meet your specific hot water needs before you make your selection.

  1. Typical Hot Water Use: Assess how much hot water your household uses on average. For instance, big families who enjoy sports or have pets almost always need a lot more hot water than if you live by yourself.
  2. How Much Space the Heater Itself Needs: The dimensions of your home can affect how effectively a water heater operates. Review all possible installation locations and consult with professionals if your model is an appropriate size.
  3. Regional Climate: Brutally cold winters mean a water heater that works harder. This reduces the efficiency of tankless models, which are best suited when there won’t be any huge jumps in water usage.
  4. Energy Prices: Your community’s fuel or electricity costs can render one option more appealing over the other.

Remember, a trained professional like those at Temperature Doctors Heating & Cooling can assist you in making a more educated decision. They understand which brands meet your specific needs before delivering a smoother installation process.
