Hot water is something we take for granted—until we don’t have it. From morning showers to dishwashing and laundry, water heaters are at the heart of every home’s daily comfort. But when it’s time to replace or upgrade, homeowners face a big decision: should you stick with a traditional tank water heater or invest in a tankless system?
At Lincoln Plumbing & Rooter, we specialize in installing, repairing, and maintaining both types of water heaters. Here’s a clear guide to help you understand the differences, advantages, and potential drawbacks of each option, so you can make the best choice for your home.
How Tank Water Heaters Work
Traditional tank water heaters store a large volume of hot water—usually between 30 and 80 gallons—and keep it heated for when you need it. They are common in many homes and are known for their reliability and affordability.
Pros of Tank Water Heaters
- Lower upfront cost compared to tankless systems
- Simple installation and replacement
- Can supply hot water to multiple fixtures simultaneously
Cons of Tank Water Heaters
- Limited supply: once the tank is empty, you’ll need to wait for it to refill and heat
- Higher utility bills due to standby heat loss
- Shorter lifespan (typically 8–12 years) compared to tankless systems
How Tankless Water Heaters Work
Tankless water heaters, also called “on-demand” units, heat water only as you need it. Instead of storing hot water, they use powerful heating elements to provide a continuous flow.
Pros of Tankless Water Heaters
- Endless hot water supply
- Energy efficiency—no standby heat loss
- Longer lifespan (up to 20 years or more with proper maintenance)
- Compact size that saves space
Cons of Tankless Water Heaters
- Higher upfront cost and installation expense
- May require electrical or gas line upgrades
- Limited flow rate—can be challenging if multiple showers and appliances run at the same time
Factors to Consider Before Choosing
When deciding between tank and tankless water heaters, consider the following:
- Household Size: Larger families may benefit from a tank with ample storage, while smaller households often thrive with a tankless unit.
- Budget: Tank water heaters are more budget-friendly upfront, but tankless units can save money long-term through lower utility bills.
- Space: If your home has limited storage or utility space, the compact size of tankless units can be a big advantage.
- Hot Water Demand: Do you often run multiple showers, laundry, and dishwashers at once? A larger tank may handle that better.
