Expert Review
The EcoSmart ECO 27 is an attractive option for Long Island homeowners wanting to go tankless on a budget. Its 0.99 UEF means virtually zero wasted energy. However, with Nassau County's cold winter groundwater temperatures (around 45°F), the effective flow rate drops to about 3 GPM — enough for one shower and a sink, but not for simultaneous heavy use. The lifetime residential warranty on the heat exchanger is a standout feature. Best suited for smaller homes or as a supplemental unit.
