Tank vs Tankless Water Heaters

When it comes time to replace your water heater, one big question comes up: Do I stick with a traditional tank water heater, or upgrade to a tankless system?

Both options have their pros and cons, and the right choice depends on your home, your lifestyle, and your budget. At Home Run Mechanical, we help Ann Arbor homeowners weigh the options and make the best call for their comfort. Here’s a breakdown of how these two systems compare.

How They Work

Tank Water Heaters

  • Store hot water in a large tank (usually 30–50 gallons)

  • Keep the water heated until it’s needed

  • When the tank is emptied, it needs time to refill and reheat

Tankless Water Heaters

  • Heat water on demand—no storage tank required

  • Provide hot water instantly and continuously

  • Use powerful gas burners or electric elements to heat water as it flows

Benefits of a Traditional Tank Water Heater

  • Lower upfront cost than tankless

  • Reliable supply of hot water for multiple uses at once

  • Simple installation and replacement

  • Works well in homes already set up with a tank system

Best for: Homeowners looking for affordability and reliability, with predictable hot water use.

Benefits of a Tankless Water Heater

  • Endless hot water—never run out during showers or laundry

  • Energy-efficient, since water is only heated when you need it

  • Compact design, freeing up storage space

  • Longer lifespan (often 20+ years with proper maintenance)

Best for: Families with high hot water demand, or homeowners looking to save energy and space long-term.

Things to Consider

  • Cost: Tankless units cost more upfront, but can save money on utilities over time.

  • Installation: Switching from tank to tankless may require plumbing or electrical upgrades.

  • Usage: If multiple people use hot water at once, tankless is ideal—but sizing matters.

  • Maintenance: Both systems need periodic flushing and checkups to maintain efficiency.

So, Which One Should You Choose?

If you want a budget-friendly, dependable solution, a traditional tank water heater is the way to go.

If you’re ready to invest in energy savings and endless hot water, a tankless water heater might be the best choice.

Either way, Home Run Mechanical has you covered. We install, repair, and maintain both types of systems—and we’ll help you make the best decision for your home.
