1 TECHNICAL SPECIFICATION OF PRODUCT
1.1 FUNCTION DESCRIPTION
After the heater is connected to electric network, the heating element starts heating water. The element is
turned on and off by a thermostat.
Thermostat can be set as per your need within the range from 7°C to 74°C. We recommend setting service
water to max temperature of 60°C. This temperature ensures the optimal operation of the heater. After
reaching the temperature set, the thermostat switches off the electric circuit and thus discontinues water
heating. The control light signals if the element is in operation (light is on) or if it is off (the light goes out).
In case of longer operation without using the heated volume the thermostat has to be set to position 5°C to
12°C (set the "snowflake" symbol on the thermostat selector) to avoid its freezing.
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
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 [kWh/24h] and indicates the amount of power
needed to maintain the set temperature. Its benefit is that it heats up water by power in an
unlimited all-day time range. The time of heating service water to the recommended
temperature of 60°C is about 31 minutes. With its design, the electric accumulation heater
TO - 20 is suitable for installations in bathrooms, lavatories, kitchens or near sanitary units of
panel flats, and complies with the requirements of Standards, with the IP 44 protection class.
