Ariston ENS40H-6 Electric Water Heater 40 Gallon

Product Description

The ARISTON ENS40H-6 is a residential electric water heater in a tall configuration, designed for whole-home domestic hot water supply. With a 40-gallon storage capacity and a first-hour delivery rating of 21 gallons per hour (GPH), this unit suits households with moderate hot water demand. Licensed plumbers and HVAC technicians typically handle installation in new construction or replacement applications where a tall-form-factor tank fits existing utility space.

The ENS40H-6 is intended for residential use in standard utility rooms, basements, garages, or dedicated mechanical spaces where a tall electric water heater is specified. The 40-gallon capacity covers typical single-family residential demand. Its tall footprint is common in applications where floor space is limited but vertical clearance is available.

Key Features

• 40-gallon storage capacity for residential hot water supply
• Tall form factor fits standard utility room and basement installations
• 21 GPH first-hour delivery rating for moderate household demand

Compatibility

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the electrical supply at the breaker panel and close the cold-water supply valve before beginning work. Verify that the dedicated circuit voltage and amperage match the unit requirements before making electrical connections. Pressure-relief valve installation and discharge piping must comply with applicable local codes.
