300 Amp minimum total service to the residence， or an upgrade to this level， is necessary to install a Tempra 36 Plus as it has a maximum power draw of 150 Amps and requires 3 separate 50 Amp breakers with 3 separate runs of 8-gauge copper wiring
Tempra tankless electric water heaters must be correctly sized and you should consult the sizing guide to determine the correct model for you
This Tempra Plus model has German patented Advanced Flow Control that automatically reduces output flow to maintain temperature if demand temporarily exceeds capacity
Requires 240 Volt or 208 Volt electric service， and has a maximum output of 36，000 Watts at 240 Volts or 27，000 Watts at 208 Volts
Supplies endless hot water at a constant and steady temperature from 68 to 140°F (20-60°C) that can be set on the front panel digital display
Flow rate you achieve from this or any tankless water heater depends on how powerful the unit is and the temperature difference between the incoming cold water and the hot water being delivered
99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
Smart microprocessor technology unique to Tempra water heaters delivers steady water temperature even when flow rate vary as taps are adjusted
Must be installed vertically， water fittings pointing down， with detachable connections such as braided flex connectors to allow periodic filter cleaning and flushing for scale， and an anti-scale filter is recommended if hard water is present
Professional installation recommended
