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
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
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
