 Traditional vs Tankless Water Heaters: Key Differences

What Are Traditional Water Heaters?

Also known as conventional or storage tank heaters, these systems are the most common type found in homes. A standard unit comprises a large insulated tank to continuously heat stored water, ensuring your hot water faucets don’t run out. Traditional systems use natural gas, electricity, oil, or propane to maintain the desired water temperatures. This makes them budget-friendly, reliable, and versatile; ideal for homes with large usage.

What Are Tankless Water Heaters

As the term suggests, tankless systems don’t require a storage tank to heat water. These modern systems use strong heating elements to heat water on demand, making them faster. In addition, tankless water heaters reduce energy loss when not in use, making them more energy efficient than conventional units. However, tankless systems use either gas or electricity, limiting them to homes with stable utility infrastructure.

The Difference Between Tankless and Traditional Water Heaters

When choosing between a tankless and a traditional water consider vital factors to ensure you make informed decisions. With that said, working with a reputable plumber can help you choose. Here are crucial factors to guide your decision and ensure you get your money’s worth.

Energy Efficiency

Energy use is a crucial consideration when choosing a water heater. As stated, water heater models heat water on demand, reducing energy waste. On the other hand, tankless systems keep water hot continuously, leading to higher energy use. Although tank systems are ideal for homes with more hot water needs, tankless models are more energy efficient. Before deciding, consult a plumber in Columbus, OH to avoid inefficiencies and disruptions to your routine. Plumbers understand how different systems function and their limits, ensuring you install the right system for your home without compromising efficiency and comfort.

Installation Complexity

Another factor when deciding which system to install is complexity. Tankless systems don’t require a tank, which makes them less rigorous to integrate into your home. However, these systems require modifications to your plumbing and electrical, or gas connections. Professional installation is crucial to navigate these complex processes and prevent costly water heater repair and replacements down the line. Conversely, traditional units are easier to install, especially when replacing an existing water heater. This makes the process straightforward and time-efficient.

Space Requirement

The space a water heater takes is a deciding factor, especially if you have limited room. A tankless system doesn’t require a storage tank to heat water, saving a lot of space. The plumber will simply install it on a wall, allowing you to maximize your indoor spaces. Traditional water heaters need ample space for the large tank, often taking up space in the garage, basement, or attic. Whether space is an issue or not, tankless systems are better, as they expand your living spaces.
