Key Factors to Consider When Choosing a 60-Amp Tankless Water Heater
1. Flow Rate (GPM)
- For smaller homes or point-of-use applications, a GPM of 2.5-4.5 is typically sufficient.
- If you need to run multiple fixtures (like a shower and kitchen sink), aim for a heater with at least 3.0 GPM to prevent fluctuations in water temperature.
2. Temperature Control and Climate
- Digital temperature control allows for precise settings, which is crucial when water temperatures vary based on climate.
- In colder climates, incoming water temperatures are lower, which can reduce GPM. Choose a model with higher GPM if you live in a cold area.
3. Energy Efficiency
- Most electric tankless water heaters are highly efficient, with ratings of 99%, meaning almost all the energy consumed goes into heating the water.
- Look for features like self-modulating technology (EcoSmart) or Advanced Flow Control (Stiebel Eltron) to optimize energy use and prevent overheating or cold water bursts.
4. Installation Space
- These units are compact and wall-mounted, saving space. Ensure you have enough room for installation near the necessary water and electrical connections.
- Consider the electrical panel capacity—if your panel isn’t able to handle the amperage, you may need an upgrade before installing a 60-amp water heater.
