Completely Redesigned
The Tempra® series has been redesigned completely inside and out -
upgraded heavy-duty electronics, a simple single flow sensor design,
a hinged cover for easy access, and Advanced Flow Control™ for the
Tempra® Plus. Welcome to the next generation of German quality.
Unlimited supply of hot water
The Tempra® continually heats water instantaneously as you require
it - and only when you require it. The Tempra® unit completely
replaces a conventional tank heater with no disruption to your
comfort and hot water needs.
Advanced Flow Control™ ensures
the temperature remains constant no matter what! Tempra Plus
featuring Advanced Flow Control. The Tempra® Plus is the most
technologically advanced tankless water heater available on the
market today. Advanced Flow Control is exclusive to the Tempra® Plus
and ensures a constant temperature output no matter how great the
hot water demand is. Advanced Flow Control technology works by
automatically adjusting the flow of water to eliminate unpleasant
temperature fluctuation. What that means to you is a consistently
satisfying experience every time, all the time!
Control temperature simply by setting a dial
Set the knob on the front cover and enjoy water temperatures between
86°F (30°C) and 140°F (60°C). Change the desired temperature at
anytime. Advanced microprocessor technology ensures that the water
temperature never deviates from the set point.

Proven reliability
Stiebel Eltron has an enviable track record of engineering
excellence and product quality. The three years parts warranty is
unique in the industry. You can depend on the Tempra® for many years
to come.
Sleek design fits in anywhere
The Tempra® takes up considerably less space than conventional tank
type water heaters and saves valuable living space.

No venting required
The Tempra® has several advantages over a gas-type tankless water
heater. Compared to many similar gas tankless models the Tempra® is
less expensive to purchase. Installation is also much simpler and
cheaper since it is not necessary to vent a Tempra® to the outside.
The
venting that a gas unit requires causes anywhere from a 10 - 20%
efficiency reduction from heat escaping out the exhaust pipe.
Furthermore, for every cubic foot of gas burned, roughly two cubic
feet of air have to be mixed in to create ideal combustion. In a
cold climate, this hurts efficiency further.
When a
gas unit fires it draws in air around it, heats the water, and then
expels warm exhaust outside. Since no house is airtight, this
suction action causes a drafting condition where cold air from the
outside seeps back in through door cracks and other parts of the
house that may not be airtight.
By
nature of the design, the Tempra® is nearly 100% efficient;
converting 100% of the electrical energy it consumes into heat. All
that heat is then transferred to the water - none is lost to the
outdoors.
