Gas vs. Electric Tankless Water Heaters: Which Is Better?
Choosing between gas and electric tankless water heaters depends on your home's setup and priorities:
1. Energy Efficiency
- **Gas tankless water heater**: 80-98% efficiency (condensing models reuse exhaust heat).
- **Electric tankless water heater**: 99% efficiency but relies on grid power (cost varies by regions).
2. Installation Costs
- **Gas tankless water heater**: Requires gas line + venting (cost varies by regions).
- **Electric tankless water heater**: Needs 200A+ electrical panel (cost varies by regions,usually cheaper than gas).
3. Performance
- **Gas tankless gas water heater**: Better for large households (16-20L/min flow rates).
- **Electric tankless water heater**: Struggles in cold climates (limited temperature rise).
4. Operating Costs
- **Gas tankless water heater**: Cheaper where natural gas is affordable (cost varies by regions).
- **Electric tankless water heater**: Higher long-term costs in areas with expensive electricity.
5. Lifespan & Maintenance
- **Gas tankless water heater**: 8 years (minimal maintenance).
- **Electric tankless water heater**: 8 years (minimal maintenance).
Our Verdict:
Gas models like **GASTEK GWH-24L** excel for whole-home hot water demand synchronously, especially for big family.
