What Is a Tankless Water Heater?
Unlike traditional tank water heaters that store 40-80 gallons of hot water, tankless units heat water on demand as it flows through the unit.
Pros of Tankless Water Heaters
- Endless hot water — Never run out during back-to-back showers
- Energy efficient — Only heats water when needed
- Space saving — Wall-mounted, compact design
- Longer lifespan — 15-20 years vs. 10-12 for tank units
- Lower operating costs — 20-30% energy savings
Cons of Tankless Water Heaters
- Higher upfront cost — $2,500-$4,500 installed
- May require upgrades — Gas line or electrical panel upgrades
- Flow rate limitations — May struggle with multiple simultaneous uses
- Maintenance required — Annual descaling recommended
