Stiebel Eltron STIEBEL-224198 Tankless Water Heater 19kw

Product Description

The Stiebel Eltron STIEBEL-224198 is a whole-house electric tankless water heater from the Tempra 20 Plus series. It delivers on-demand hot water without a storage tank, heating water only as it flows through the unit. Rated at 19 kilowatts and 240 volts, it is designed to meet the simultaneous hot water demands of multiple fixtures in a residential setting. The unit features electronic temperature control that maintains a consistent output temperature and Advanced Flow Control technology that moderates water flow rate to preserve steady hot water delivery when demand approaches the unit's capacity.

The Tempra 20 Plus is intended for whole-house applications in moderate-climate regions or as a primary heater in smaller households. It is also suited for multiple point-of-use scenarios where a single centralized unit serves several fixtures at once, such as showers, sinks, and a dishwasher running simultaneously. The copper-sheathed heating element is encapsulated in a copper cylinder, which supports efficient heat transfer and long service life. The seismic-proof construction is appropriate for installations in regions with seismic activity requirements.

Key Features

• Advanced Flow Control technology reduces flow rate to maintain consistent hot water temperature under high demand
• Electronic temperature control for precise, stable output temperature
• Copper-sheathed heating element housed in a copper cylinder for efficient heat transfer
• Tankless design eliminates standby heat loss associated with storage tank heaters
• Seismic-proof construction suitable for installations in seismically active regions
• Unlimited on-demand hot water with no recovery wait time

Compatibility

Designed as an OEM whole-house electric tankless water heater replacement or new installation for residential applications requiring a 240-volt, 19-kilowatt on-demand heating solution.

Installation Notes

Installation must be performed by a licensed plumber or electrician in accordance with local plumbing and electrical codes, including NEC requirements for dedicated circuit sizing and overcurrent protection appropriate to a 19-kilowatt, 240-volt load. Shut off the main electrical supply to the installation circuit before any wiring work begins and close the cold water supply valve before connecting plumbing. Do not energize the unit until it is fully filled with water, as operating the heating elements dry will cause damage. Consult local authority having jurisdiction for permit requirements before installation.
