Without a doubt, tank water heaters have proven then test of time, but since they started gaining popularity in the 1970s, tankless innovations have made them a worthy contender. So, which one is right for you?
A tankless water heater heats water only when needed, meaning it doesn’t store hot water in a tank, while a tank water heater continuously heats and stores a large volume of water in a tank, ready to be used at any time; tankless heaters are generally more energy efficient due to their on-demand heating, but often have a higher initial cost compared to tank water heaters.
Key Differences:
- Heating Method: Tankless: Heats water instantly as it flows through the unit; Tank: Heats a large volume of water and stores it in a tank.
- Energy Efficiency: Tankless: Typically more energy efficient as it only heats water when needed, reducing standby heat loss.
- Cost: Tankless: Usually higher initial purchase price.
- Lifespan: Tankless: Generally lasts longer than a tank water heater.
- Space Requirements: Tankless: Smaller footprint as it doesn’t need a large tank.
When to Choose a Tankless Water Heater:
✔ High energy efficiency is a priority
✔ Limited space available
✔ Consistent hot water demand, even during multiple uses
✔ You want to spend a little more upfront in exchange for long-term energy benefits
When to Choose a Tank Water Heater:
✔ Lower upfront cost is important
✔ Smaller household with moderate hot water needs
✔ Easier installation process
✔ Natural gas is not an option
