6. Overview

6.1 General Description

The Mini tankless water heater differs from conventional storage

type water heaters in several ways. It does not store hot water.

Instead, water is heated instantaneously as it ﬂows through the

unit. The powerful heating elements are activated by a ﬂow

switch as water is drawn from a hot water faucet connected to

the Mini. Due to the absence of stand-by losses, the Mini offers

greater energy efﬁciency than storage type water heaters. The

unit will continuously supply hot water as long as the faucet is

open.

The temperature of the hot water delivered by the Mini depends

on the wattage of the heating element, the temperature of the

incoming cold water, and the water ﬂow rate through the unit.

In order for the Mini to operate properly, it must be carefully

matched to the application.

In case you have questions regarding the way you plan to use the

Mini, please call our technical service line at 800-582-8423 (USA

and Canada). For service outside the U.S. and Canada, please call

us at USA 413-247-3380. You can also e-mail us at info@stiebel-

eltron-usa.com or fax us at 413-247-3369.
