Eemax HomeAdvantage II 27 kW Whole-House Electric Tankless Review
The Eemax HomeAdvantage II 27 kW is the flagship whole-house electric tankless in Eemax's residential line. 27 kW capacity with commercial-grade brass construction throughout. Sized for whole-house demand in any US climate.
Specs: 27 kW, three 40-amp double-pole breakers, 113A continuous draw at 240V. Requires 200A service. Brass construction (commercial-grade durability). Patented modulation electronics. 3-year warranty on heat exchanger.
Capacity: 3.0 GPM at a 60°F rise (cold-climate winter) or 4.5 GPM at a 40°F rise (Sun Belt). Handles 2-bathroom sequential demand in cold climates, 2-bath simultaneous in warm climates.
Eemax positioning differs from EcoSmart in the same capacity class:
- Commercial-grade brass construction throughout — durability advantage for high-cycle use
- Shorter warranty (3-year vs lifetime for EcoSmart heat exchanger)
- Higher price ($1,400 vs $600 for EcoSmart ECO 27)
Right buyer: light commercial application or residential application valuing commercial-grade build over the longer warranty terms of EcoSmart. About $1,400 unit, $2,800 installed.
