GENERAL
Description
EN
Electrical tank water heaters are used for supply of hot water in country houses, cottages, baths,
and other utility spaces, which are not connected to the central hot water supply network. Such
heaters can also be used as standby equipment in apartments for the preventive maintenance
period of the hot water supply network.
The operation principle of the water heater assumes that water pressure in the water heater
meets water pressure in the water main. As water is consumed, the water heater tank is continu-
ously refilled with cold water.
The electrical tank water heater of Niagara series is designed for heating of tap water in house-
hold use. It is capable to prepare a lot of hot water and maintain the set temperature auto-
matically. The water heater has a steel outer casing. Water is heated in a steel enameled tank
using a copper heating element. Heat insulation made of an environmentally friendly material is
provided between the outer casing and steel tank. The dense insulation layer ensures reduction
of heat loss and significant saving of electrical energy.
For mitigation of corrosion effect and provision of consumers with water free from contamina-
tion, the water heater is equipped with a magnesium anode of extended length. The water heater
has a water heating indicator and a water temperature control knob located on the bottom
cover. The knob controls an integrated thermostat allowing the user to set various water heating
temperatures in the range from +35°C to +75°C. A temperature limiter installed in the appliance
excludes overheating of water above 88°C, while a combined check valve / pressure safety valve
ensures safe operation of the water heater. If pressure inside the tank exceeds 0.75 MPa, the
pressure safety valve will automatically open and exclude rupture of the casing.
