Overview of Water Heater Types
What Is a Tank Water Heater?
A tank water heater stores a set amount of hot water—typically 30 to 80 gallons—and keeps it heated at all times. These systems are powered by electricity, natural gas, or oil and are common in older homes and multi-family buildings across NYC.
What Is a Tankless Water Heater?
Also known as on-demand water heaters, tankless units heat water only when needed. They don’t store hot water but activate when a hot water tap is turned on. These compact units are wall-mounted and powered by gas or electricity.
Pros and Cons of Tank Water Heaters
Pros

Cons

- Larger footprint, taking up significant floor space
Pros and Cons of Tankless Water Heaters
Pros
- Highly energy-efficient—no standby heat loss
- Provides a continuous hot water supply
- Compact, wall-mounted design saves space
- Longer lifespan (15–20+ years with maintenance)
Cons

Which Water Heater Is Better for New York Homes and Businesses?
For Residential Homes
Traditional tank heaters work well for smaller households or homes with modest hot water needs. However, NYC apartments and townhomes often benefit from space-saving tankless systems, perfect for maximizing living space and reducing utility bills.
For Commercial Properties
Tankless systems are ideal for businesses such as salons, cafés, and office buildings where hot water usage is spread throughout the day. Multiple tankless units or commercial-grade tank systems may be appropriate for larger businesses or buildings with heavy usage.
Installation Requirements and Considerations
Choosing between tank and tankless water heaters isn’t just about preference—it also depends on your building’s infrastructure.
- Tankless heaters may require upgraded gas lines or dedicated 240V electrical circuits.
- Gas tankless units require proper ventilation (usually outdoor venting or flue)
- Permits and NYC plumbing code compliance are necessary for all water heater installations.
If you’re unsure what space allows, a licensed plumber can help you evaluate your system and make an informed decision. Learn more on our Plumbing Services page.
Maintenance and Long-Term Costs
Tank Heaters
- Require annual flushing to remove sediment buildup
- Shorter lifespan (typically 8–12 years)
- Energy costs are higher due to constant reheating
Tankless Heaters
- Should be descaled annually in hard water areas like NYC
- Last significantly longer with proper maintenance
- Reduced monthly energy costs can offset higher initial investment

Can I install a tankless water heater in an apartment?
In many cases, yes. However, you’ll need proper permits, space, and possibly electrical or gas line upgrades.

There’s no one-size-fits-all answer when choosing between tank and tankless water heaters in New York. Your decision should be based on energy efficiency goals, space availability, usage patterns, and budget. While tank water heaters offer affordability and simplicity, tankless systems provide long-term savings and endless hot water, which is especially beneficial in NYC’s compact living environments.
