Stiebel Eltron Tempra 20 Plus 3.7 GPM 19.2 kW Whole House Tankless Electric Water Heater

PRODUCT DESCRIPTION

Stiebel Eltron developed tankless electric water heating technology almost 90 years ago and continues as the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products. Our Tempra models are whole house tankless electric water heaters, never wasting energy storing hot water, but delivering it as you need it, for as long as you need it. The compact design needs no venting, allowing installation close to your draw off points, making your wait for hot water as short as possible and maximizing your energy savings. Tempra tankless water heaters are sized based on the number of bathrooms and your climate. Refer to the Tempra Sizing Guide under 'More Views' to determine which model you need. Call Stiebel Eltron at 800.582.8423 if you have high flow showers, or any sizing questions. Tempra water heaters supply water at a constant temperature from 86 to 140 degrees F that is settable on the front panel. We recommend setting the actual highest temperature you use, typically 107 degrees for a shower. Tempra Plus models incorporate an Advanced Flow Control that automatically reduces flow to deliver water at the set point if demand exceeds capacity. Regular Tempra models do not have this feature and should be considered if this is not of concern. Tempra 20 models provide hot water for 1 or 2 bathrooms in Warm Climates, or 1 bathroom in Cool Climates.

• Professional installation required
• Tempra 20 models require 208 or 240 volt electric service, with a maximum draw of 14,400 watts at 208 volts or 19,200 watts at 240 volts
• A minimum of 200 amp total service to the residence is necessary, with 2 separate 50 amp breakers and 8 gauge copper wiring for the Tempra 20
• The flow rate you achieve from a Tempra 20 Plus may less than 3.7 GPM as that figure is based on heating incoming water 35 degrees F which may not be the temperature rise necessary for your area
• Tempra tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank-type water heaters
• Tempras use only the amount of energy necessary to heat the water needed
• The sleek European design is considerably smaller than a tank, saving space and allowing flexibility to determine the best location for installation
• Tempra units must be installed vertically with the water fittings pointing down
• Tempra tankless water heaters work better than tank-type water heaters in hard water environments because they can be set to lower temperatures, which minimizes scale formation
• Water connections for Tempra water heaters must be detachable (such as braided steel flex connectors) to allow periodic filter cleaning, including flushing for scale if hard water is present
• Tempra tankless water heaters are ETL Listed for compliance with CSA and UL safety standards in the US and Canada
• Tempra tankless electric water heaters are exempt from seismic code
• Overheat safety protection and thermal protection reset are standard
• See warranty for complete details of the 3-year residential and commercial warranty against defects in workmanship and materials under normal use
• This is a Tempra Plus model that incorporates an Advanced Flow Control to automatically reduce flow to deliver water at the set point if demand exceeds capacity
