Conclusion
This tankless water heater does its job well but finding its parts becomes a bit difficult after a while. Another drawback is that it requires two 40amp breakers. This makes it a bad choice if saving energy is your top priority as the unit will consume a lot of energy. Buy it if you require plenty of hot water or have a bigger family.
