1 APPLIANCE TECHNICAL SPECIFICATION
1.1 FUNCTION DESCRIPTION
The water heater as well as the storage tank (thereinafter the appliance) is designed for accumulation
heating of service water using electricity or thermal energy via an exchanger. Water is heated by an electric
element or a heat exchanger in an enamelled thermally insulated vessel at the time defined by the power
supplier. The element is at the time of heating controlled by a thermostat the temperature of which can be
adjusted continuously (within the range between 5°C and 74°C). Once the selected temperature is reached,
heating interrupts automatically. Water accumulated in the vessel is then used for the consumption. The
appliance keeps constant pressure of water from the water main. Is the combination faucet hot water valve
opened, water from the water supply conduit pressed out by cold water pressure flows out of the
appliance. Hot water flows out through the top part, and water flowing in remains in the bottom part of the
appliance. Pressure principle allows hot water withdrawal at any place from the appliance (Figure 5).
1.2 ADVICE FOR CUSTOMERS
1.2.1 HOT WATER CONSUMPTION
Consumption of hot water in households depends on the number of people, amount of
sanitary equipment, length, diameter and insulation of piping in the flat, or on individual
habits of users. The cheapest option of water heating comes at the time when the
electricity rate is reduced.
Find out in what time intervals your electricity supplier provides reduced tariff and,
depending on that information, select relevant volume and power input of the appliance so
that your hot water consumption covered the needs of your household.
1.2.2 ENERGY SAVING
Hot utility water reservoir is insulated by means of top-quality polyurethane foam with zero
CFCs content. Adjust the temperature of the appliance's thermostat to that level only that
you need to run your home. Thus you will reduce electricity consumption, as well as the
amount of lime sediments on the walls of the receptacle and on the heat exchanger.
