Induction - elektric boiler PEREKO π - PI - 21 kW on electricity
Π (PI) is designed for low-temperature water central heating systems, where temperature in system does not exceed 90°C.It can be installed in central heating installations made of steel, copper, polyethylene, polypropylene, CPVC, etc. pipes on which heaters of all types are mounted, as well as it cooperates with all types of heaters and air curtains.
Boiler Π (PI) is an inductive central heating boiler based on an electromagnetic device. The heat is created by an electromagnetic field directly in heating chamber which is located on the transformer columns. This design allows to reduce loss of electromagnetic field to a minimum. Exchanger chamber is made of high quality acid resistant steel. Expected boiler life is 50 years. Main element of boiler Π it is a three-phase dry transformer with a compact secondary winding. Secondary winding forms a heating chamber. All heat generated in chamber is transferred entirely to heating medium (water) which flows through chamber.)
WARRANTY: For induction boilers of &pi series; at the date of purchase, a standard 24-month warranty is given for smooth running of boiler as well as a 24-month warranty on components such as controller or sensors (etc.). However, it is possible to extend warranty even for period 20 years by registering boiler on manufacturer's website and receiving a written 20 year warranty for boiler.)

Boiler is an electromagnetic device that converts three-phase electrical energy (current) into heat by means of an electromagnetic field. In this process water is subjected to electromagnetic treatment.

To ensure the most economical operation of induction boiler, it is best to combine it with a buffer, accumulation tank, together with an electrical connection operating at a tariff (G12), i.e. night-time. If this is not required by other heat sources, a buffer without coils is recommended. By buffer, accumulation tank, we mean an insulated tank, which has the task of accumulating the heat energy produced by the boiler and putting this energy into the installation when the boiler is not working. During the operation of the boiler the circulation pump constantly mixes water in buffer, drawing cold water from its lower part and feeding hot water from upper part. For an average house it is enough to install a storage tank, buffer, with a capacity of about 700 - 800 liters of water. Dimensions of such a buffers are so small that they can be installed in any boiler room.
