The Eemax LavAdvantage line is purpose-built for commercial lavatory (handwash sink) applications. These are point-of-use electric tankless heaters installed under or adjacent to a single sink, sized specifically for handwash flow rates and the commercial code compliance requirements that public restroom installations must meet.
LavAdvantage vs general POU tankless
General point-of-use tankless heaters handle various single-fixture applications. LavAdvantage is engineered for the specific demands of commercial lavatory:
- UL/ETL listings specific to commercial installation (food service, healthcare, education)
- ASSE 1070 compliance (anti-scald tempering valve integration where required)
- Flow rates matched to faucet aerators (typically 0.5 GPM commercial)
- Recovery and standby behavior optimized for intermittent commercial use patterns
LavAdvantage capacities
Available in 3.0, 3.5, and 4.5 kW variants depending on flow rate and temperature rise requirements. The 3.5 kW version at 0.5 GPM delivers approximately 105°F outlet from 65°F inlet — appropriate for handwash applications. Sizing depends on actual inlet water temperature at the site and the desired outlet temperature.
Mixing valve integration
Commercial lavatory code typically requires anti-scald protection via mixing valve. LavAdvantage installations either include a separate ASSE 1070 mixing valve at the fixture, or use a model with integrated tempering. Verify local code requirements for your specific application — restaurants, healthcare, and educational facilities have stricter requirements than office buildings.
Installation requirements
- Dedicated 20–30A 240V circuit (depending on kW rating)
- Cold water supply with isolation valve
- Hot outlet to faucet or mixing valve
- Mounting bracket on wall or under-counter
- GFCI protection per local code
Where LavAdvantage installations make sense
Public restroom retrofits where running hot water from a central source is impractical (long pipe runs, energy loss). Food service handwash stations requiring instant hot water for code compliance. Healthcare facility patient-room handwash sinks. Educational facility restroom retrofits where central hot water capacity is insufficient.
Maintenance schedule
LavAdvantage in commercial service requires more frequent maintenance than residential. Inlet screen cleaning monthly. Annual descaling (or more frequent in hard-water areas). Element inspection at year 3. Most commercial installations contract with a service company for quarterly checks — the cost is justified by avoiding outage during business hours.
Lifespan in commercial service
LavAdvantage units in typical commercial restroom service achieve 10–15 year lifespans with proper maintenance. Heavy-use facilities (high-traffic restaurant, large school) may see closer to 8–10 years. Element replacement is the most common service event at year 5–7.
