Conventional Storage Tank Water Heaters: The Reliable Choice

Let's take a closer look at conventional storage tank water heaters first. That sizable storage tank is the key feature here, holding onto a generous supply of water that’s continually heated. Whenever you need hot water, a tank water heater is ready to supply it.


  • Budget-Friendly Installation: Tank water heaters typically have lower up-front installation costs, thanks in part to a less complex design.
  • Easier Maintenance: A streamlined design also translates into fewer potential maintenance needs.


  • Continuous Energy Use: Tank water heaters have to keep water continuously heated, which inevitably leads to wasted energy if you’re not constantly using that water.
  • Bulky Size: The tank itself could become a hurdle in smaller 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 check out tankless water heaters, an innovative alternative that’s relatively modern. Compared to tank models, tankless water heaters operate when needed. They’re heating up water only when requested, thanks to robust heating elements as the water comes through the system.


  • Greater Energy Savings: Tankless models are much more energy efficient since they’re not always on.
  • Longer Life Span: With proper maintenance from a certified expert, tankless water heaters can enjoy many years of service.


  • Bigger Price Tag Up Front: Initial installation costs are higher as a result of the more intricate design.
  • More Frequent Maintenance: Tankless models do best when provided more regular servicing to keep their key elements working efficiently.
  • Compatibility Issues with Old Plumbing: Older homes aren’t always equipped for a tankless water heater. Plumbers can modify 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 going with the stronger energy efficiency that tankless water heaters provide. But this also depends on variables like 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. For instance, big families who are active in sports or have pets almost always need a lot more hot water than a single person living alone.
  2. Space for Installation: The dimensions of your home can affect how efficient a water heater operates. Consider all possible installation locations and consult with professionals if your model is capable of fitting where you want it go.
  3. Regional Climate: Long winters mean a water heater that works harder. This reduces the efficiency of tankless models, which are most efficient when there won’t be any large fluctuations in water usage.
  4. Energy Prices: Your local energy prices can make one option more attractive over the other.

Keep in mind, seasoned installers like those at TopTec can aid you in making a more informed decision. They understand which brands meet your specific needs before ensuring a smoother installation process.
