Eemax SPEX48 Electric Tankless Water Heater 4.8 Kw

Product Description

The EEMAX SPEX48 is a commercial-grade electric tankless water heater designed for point-of-use hot water delivery without a storage tank. Rated at 4.8 kW and 240 volts single-phase, it draws up to 20 amps and heats water on demand as it passes through the unit. The multi-directional feed design allows flexible inlet and outlet plumbing connections, reducing installation constraints in tight spaces. Water connections are 3/8 inch compression fittings. Licensed plumbers and commercial contractors install this unit in commercial facilities where a compact, dedicated hot water source is required at a single fixture or zone.

The SPEX48 is suited for commercial point-of-use applications such as restroom hand-washing sinks, break room sinks, and utility stations where running a long hot water line from a central heater is impractical. Its tankless design eliminates standby heat loss, making it appropriate for low-flow, intermittent-use fixtures in offices, light commercial buildings, and service facilities. Single-phase 240-volt power is standard in most commercial panel configurations, simplifying electrical integration.

Key Features

• 4.8 kW heating capacity for point-of-use on-demand hot water
• 240 volt single-phase operation at 20 amps
• Multi-directional feed design allows flexible inlet and outlet plumbing routing
• 3/8 inch compression water connections for straightforward plumbing tie-in
• Tankless design eliminates standby heat loss at the fixture
• Commercial-rated construction for professional installation environments

Compatibility

Designed as a commercial point-of-use electric tankless water heater suitable for single-fixture hot water supply in low-flow commercial applications.

Installation Notes

Installation must be performed by a licensed plumber and a licensed electrician, as the unit requires both a dedicated 240-volt circuit and compression plumbing connections. Shut off water supply and de-energize the circuit breaker before making any connections. A dedicated 20-amp double-pole breaker is required; consult local NEC requirements for wire gauge and breaker sizing. Do not operate the unit without water flow established through the heater to avoid dry-fire damage to the heating element.
