Tankless vs. Tank Water Heaters: Which One is Best?

Hot water. It’s a household essential, but have you ever stopped to think about what’s behind the scenes making those steamy showers possible? We’re talking about your water heater, of course. But when it comes to choosing a new one, you might be surprised to learn there’s more than one option out there. The two main contenders? Standard tank and tankless water heaters.

Before you dive headfirst into researching gallons and BTUs, let’s break down the key differences between these two water heating systems. Understanding how they work, their pros and cons, and how they fit your lifestyle will help you select the perfect fit for your home. After all, who wants to be stuck with lukewarm showers or a constantly running (and energy-guzzling) water heater? Definitely not us! So, let’s take a look.

Tank Water Heaters

A traditional tank water heater works by constantly heating a large tank of water to a set temperature. This means you always have hot water on demand, but it also means you’re constantly using energy to keep that water hot, even when you’re not using it. Standard (or traditional) tank water heaters are available in both gas and electric models, allowing you to pick the fuel source that suits you and your needs best.

Pros:

  • Lower initial cost
  • Easier to install
  • Steady supply of hot water, even during high demand periods
  • Works with both natural gas and propane

Cons:

  • Less energy-efficient than tankless water heaters
  • They can run out of hot water if multiple hot water sources are used simultaneously (e.g., taking a shower while running the dishwasher)
  • Takes up more space

Tankless Water Heaters

Contrary to standard units, tankless water heaters heat water on demand. When you turn on a hot water tap, the unit kicks in and heats the water as it flows through. This can be a much more energy-efficient way to heat water, as you’re only using energy when you actually need hot water.

Pros:

  • More energy-efficient, especially in homes with low hot water usage
  • Endless supply of hot water (as long as the unit is properly sized)
  • Compact design takes up less space

Cons:

  • Higher initial cost
  • More complex installation process, may require additional plumbing upgrades
  • Flow rate may not be sufficient for multiple hot water sources being used simultaneously
  • May not be suitable for cold climates

Here are some additional factors to consider when making your decision:

  • Your hot water usage: If you have a large family or use a lot of hot water, a tank water heater may be a better choice to ensure you don’t run out. Those water heaters range from 40 gallon – 120 gallon usually. Even though tankless systems have an endless supply of hot water, the flow rate might not be able to keep up with high demand of hot water with larger families.
  • Your fuel source: Both tank and tankless units are available in gas and electric models. Gas models are typically more powerful and efficient, but electric models may be a better option if you have limited space or access to natural gas.
  • Your budget: Tankless water heaters usually have a higher upfront cost than tank water heaters. However, they can save you quite a bit of money on your energy bills over time.
