2. Understanding Tankless Water Heaters
What exactly is a tankless water heater, and how does it differ from traditional models?
Tankless water heaters, also known as on-demand water heaters, heat water directly without using a storage tank. High-powered burners heat the water as it passes through a heat exchanger, providing hot water only when needed. These units are powered by either electricity or gas.
2.1. Traditional Water Heaters vs. Tankless
Most older homes use traditional water heaters with tanks, typically holding 30 to 50 gallons of water. These tanks heat and store water, ready for use. Like tankless models, traditional water heaters can be powered by natural gas or electricity.
2.2. Key Differences Summarized
| Feature | Traditional Water Heater | Tankless Water Heater |
|---|---|---|
| Water Storage | Stores 30-50 gallons | Heats on demand |
| Energy Efficiency | Lower | Higher |
| Lifespan | 10-12 years | 20+ years |
| Space Requirement | Larger | Smaller |
| Hot Water Supply | Limited by tank size | Unlimited, but can vary |
| Repair Complexity | Often requires full replacement | Individual components can be replaced |
