3. Construction of the water heater

The DAFI heater consists of the heating block placed on the water unit. The

water unit is made of the base which is provided with short stub pipes for

supply of cold water and discharge of hot water. Inside the heater, there is

the heating block provided with water channels with the heating element

(heating strand) and elements used for supplying electricity. The whole devi-

ce is enclosed in an enclosure.

4. Operating principle

After opening the hot water valve, the flowing water causes the flow con-

nector to be switched on (power is supplied to the heating element) and

the flowing water directed to the tap is heated. Water temperature depends

on the pressure and temperature of the water flowing into the heater. The

closure of the hot water valve causes the flow connector to be switched off

(the power supply to the heating element is interrupted). The temperature

of the water flowing into the heater can be adjusted only by closing and

opening of the hot water valve slowly within the scope of outflow of the hot

water from the heater.

The smaller water flow means the higher temperature.

The temperature of hot water flowing

out of the heater is adjusted

by closing or opening of the

hot water valve slowly.
