EcoSmart ECO 36 Review

Easy to Use, Very Adjustable, and Self-Modulating

Though you need hot water for cooking meals, washing yourself and cleaning your home, some water heaters are better than others. Tankless models do not have the large tank that other models do and let you save money on heating costs. Water moves over heated coils to reach the temperature that you desire.

The EcoSmart ECO 36 36kw 240V Electric is one of the excellent tankless water heaters we’ve seen. It can help you save significantly on your water heating bills and also save on the space that your old product used.
