The reality is that both types have their unique advantages and disadvantages. When deciding on any addition to your home for better heating and air, Atlanta HVAC experts are the best resource to know for certain which is best for you.

However in this article, you will learn the key differences between the two water heater types. That way, you can be more prepared to make an informed decision for your home.

Tank vs Tankless Water Heater: The Differences

Which is better — A tank water heater or a tankless water heater? Well, first it helps to know the fundamental differences that make each type unique, both good and bad.

Tank Water Heaters

A tank water heater, as its name suggests, uses a tank that stores hot water. The hot water storage tank has several components inside to heat up cold water.

The tank is connected to both a cold water supply and a heat source via gas or electricity. The incoming water is heated and rises to the top, making it available for your hot water needs.

Tank Water Heater Pros

  • Lower upfront cost
  • Can meet higher peak water demand for multiple people
  • Heats more water at one time, before it’s needed
  • Easier to use and to repair

Tank Water Heater Cons

  • Longer waiting period for hot water to refill
  • Only lasts around 10 years
  • Energy bill is higher
  • More prone to leaks which are inconvenient and can damage the home

Tankless Water Heaters

A tankless water heater doesn’t need a hot water storage tank. It heats water typically within a few minutes, as you need it. Typically, tankless water heaters are powered by gas or electricity.

The power source allows a heat exchanger to rapidly heat up incoming water in real time. So when you turn on hot water, you’re not pulling from a storage tank but rather the water is passing through the heater and flowing to your faucet or showerhead.

You may have heard that tankless water heaters have a higher cost at the beginning, so is a tankless hot water heater worth it? Here’s a look at the pros and cons:

Tankless Water Heater Pros

  • More energy efficient, heating the right amount of water on demand
  • Smaller, allowing you to use more of your home’s space
  • Lasts 2x longer, up to about 20 years
  • Less likely to leak

Tankless Water Heater Cons

  • Higher upfront cost
  • May need to install additional lines or power sources
  • Not as widespread or easy to find
  • May need to wait longer for hot water

Tank vs Tankless Water Heater — Costs

The cost of your tankless or tank water heater is an important factor in assuring you can enjoy hot water without breaking the bank.

Every tank and tankless water heating unit is unique, including total price. Furthermore, different HVAC professionals charge different installation fees.

While you’ll need to talk with an expert to get exact pricing, it’s helpful to know if you are looking for the lowest short-term cost or the lowest long-term cost.

Whereas water heaters with tanks cost less upfront, they may end up costing more in the long run due to a shorter lifespan and more maintenance.

On the other hand, water heaters without tanks tend to come at a higher initial price point, while saving you significant maintenance and replacement costs over the years.
