1 PRODUCT TECHNICAL SPECIFICATION
1.1 FUNCTION DESCRIPTION
The heater is designed for accumulation heating of service water using electricity. Water is heated
by an electric element in an enamelled thermally insulated tank 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 tank is then used for consumption. The tank keeps
constant pressure of water from the water main. If the combination faucet hot water valve is opened, water
from the water supply conduit pressed out by cold water pressure flows out of the heater.
Hot water flows
out through the top part, and water flowing in remains in the bottom part of the heater. Pressure principle
allows hot water withdrawal at any place from the heater.
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 heater 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 heater'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 electric element's pit.
1.2.3 EMERGENCY POWER CONSUMPTION
If no heated water is taken from the tank, a small amount of heat leaks. This loss is measured
for a period of 24 hours at the temperature of 65°C in the heater, and at 20°C in its ambient
area.
The resulting value is expressed in units [kWh/24h] and indicates the amount of power
needed to maintain the set temperature.
