Tank vs. Tankless: Pros and Cons
Every household has different needs. We’ll help you compare the advantages of each type of water heater so you can choose the best fit.
Traditional Tank Water Heaters:
- Store heated water in a 30–80 gallon tank
- More affordable upfront
- Simpler to install and repair
- May run out of hot water with heavy use
- Larger footprint requires dedicated floor space
Tankless Water Heaters:
- Provide hot water on demand, without storage
- Extremely energy efficient
- Endless hot water for large families or heavy use
- Compact wall-mounted design saves space
- Higher initial investment but long-term savings
Whether you opt for a tank or tankless system, we install only top-rated, manufacturer-approved units designed for durability and performance.

When Is It Time to Replace Your Water Heater?
While many issues can be repaired affordably, it’s not always the best solution. Here’s how to tell when replacement might be the smarter option:
- Your unit is more than 10–12 years old
- You hear loud banging or rumbling noises from the tank
- Water is discolored, rusty, or smells metallic
- You experience inconsistent hot water or water that never gets hot enough
- Leaks around the base or visible corrosion on the tank
- You’ve had to repair the unit more than once in the past year
We’ll always provide an honest recommendation based on your current unit’s condition, your budget, and your home’s hot water needs.
