Introduction

5.1

About the water heater

The AMP water heater is intended for heating
water for sanitary purposes.
The AMP is a electric storage water heater. The
electric heating elements transfer their heat
directly to the water.
5.2

Working principle

Cold water enters the tank through the water
inlet. When the water temperature drops beneath
the set temperature, the electrical heating
elements are activated and the water is heated.
The heating elements directly transfer the heat to
the water and the hot water leaves the tank
through the water outlet.

The tank of the water heater has to be
completely filled during operation. The tank at
least must remain under mains water supply
pressure at any time. Fresh cold water is
immediately added when hot water is drawn from
the water heater. The regulation thermostat on
each heating element, is equipped with a contact
thermostat. This thermostat measures the water
temperature, on the outside of the tank.
