You’ll have to analyze several factors when deciding whether to buy a traditional water heater or a tankless model. The best unit for your home depends on:
1. The number of people living in your home
2. Upfront and annual operating cost
3. The energy efficiency
4. Lifespan
5. Fuel type, availability, and its cost Maintenance and repair information
