Eemax HomeAdvantage II 24 kW Whole-House Electric Tankless Water Heater
Eemax HomeAdvantage II 24 kW Whole-House Electric Tankless Water Heater Review
The Eemax HomeAdvantage II 24 kW is a whole-house electric tankless water heater, positioned in Eemax's residential lineup as the mid-size option between smaller point-of-use units and the 27 kW HomeAdvantage II flagship.
Specs: 24 kW, two 50-amp double-pole breakers, 100A continuous draw at 240V. Requires 200A service or 100A service with substantial load-shed. Brass construction throughout (commercial-grade durability versus EcoSmart's plastic-housing parts). Patented modulation electronics.
Capacity: 2.9 GPM at a 60°F rise (cold-climate winter) or 4.2 GPM at a 40°F rise (Sun Belt). Right-sized for 2-bath warm-climate homes or 1-2 bath cold-climate homes with sequential demand.
Eemax positioning differs from competitors:
- Commercial-grade brass construction throughout — higher durability for higher cycling than typical residential
- Shorter warranty than EcoSmart (3-year vs lifetime for the heat exchanger)
- Significantly higher price ($1,200 vs $400-$600 for EcoSmart equivalent)
Right buyer: light commercial application (light commercial water heating), or residential application where the user values commercial-grade build over the longer warranty terms of EcoSmart. About $1,200 unit, $2,400 installed.
