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.
