1 PRODUCT TECHNICAL SPECIFICATION

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. At the

time of the heating, the element is controlled by thermostat on which the desired temperature can be set

(ranging from 5 to 74℃). 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.

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.

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.

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.
