EcoSmart ECO MINI 2.5-Gallon Point-of-Use Mini-Tank Review
The EcoSmart ECO MINI 2.5-Gallon is a small mini-tank water heater designed for point-of-use applications where even the 4-gallon ECO MINI 4 is oversized. The 2.5-gallon reservoir provides instant hot water at a single low-demand fixture without the long supply-line wait from a distant household water heater.
Specs: 2.5 gallons stored, 1440W heating element on standard 120V (no 240V required), recovery rate roughly 6 gallons per hour, wall-mount or floor-stand form factor. 1/2" NPT connections. About 10" diameter × 14" tall.
Use cases: handwash basin in a powder room far from the main heater, secondary kitchen sink in a converted basement (wet bar), garage utility sink, ADU kitchenette, outdoor mudroom sink. The 2.5-gallon capacity supports approximately 30 seconds of moderate flow at full hot before requiring recovery time — fine for handwash use, inadequate for sustained tasks.
Right buyer: very specific point-of-use application where the bigger ECO MINI 4 or 7 would be oversized. The space-savings versus a 6-gallon unit are real but small (about 30% smaller footprint).
About $130 unit, $250–$400 installed. 6-year warranty on the tank, 5 years on parts. Reasonable DIY install for any homeowner with basic plumbing skill.
