heat exchanger
, which has number of electric heaters, allowing easy
maintenance and operation;
•
control module
, which allows manual adjustment of the thermal capacity
and operating mode of the boiler;
•
circulating pump,
which makes forced movement of the heat transport
media (the circulating water). The pump has serially connected mechanical
