Source: ecosmartus.com (verified 2026-07-11) · corroborated by tankthetank.com. The EcoSmart manufacturer product page (ecosmartus.com) confirms this is the ECO 24, a 24 kW / 240 V electric tankless unit, and provides its spec table: 24 kW power input, 0.3 GPM activation flow, 80–140°F digital temperature range, 14.25 lb weight, no venting required (electric), and a stated efficiency of "UEF up to .94"; it lists no price. Model identity is corroborated by Tank The Tank, whose "EcoSmart ECO-24 24KW" listing matches the 24 kW / 240 V / 100 A / 3×40 DP electrical profile and supplies the US retail price of $ 525.00 with free shipping. An Amazon listing (Model Number ECO24, Style Name ECO 24) further confirmed the exact model, but rendered its price in EUR, so it was not used for pricing; maxFlowRateGpm was left null because the manufacturer table states no peak GPM and retailer figures conflict.
