The boiler Π (PI) is intended for low-temperature central heating installations, where the temperature of the heating medium does not exceed 90 ° C. It can be installed in installations made of steel, copper, polyethylene, polypropylene, CPVC, etc. and with all types of radiators installed as well as heaters and air curtains.
The Π (PI) boiler is an induction central heating boiler based on an electromagnetic device. The heat is generated by means of the electromagnetic field directly in the heating chamber located on the transformer's columns. This design allows to reduce the electromagnetic field losses. The chamber itself is made of high quality acid resistant steel. The estimated lifetime of the boiler is 50 years. The main element of the Π boiler is a three-phase transformer with a compact secondary winding. The secondary winding forms a heating chamber in this construction.The heat generated in the chamber is entirely transferred to the water that flows through the chamber.
WARRANTY: For induction boilers of the π series, on the day of purchase, a standard warranty is granted for a period of 24 months for efficient boiler operation, as well as a 24-month warranty for components such as eg a controller or sensors (etc.). However, it is possible to extend the warranty even for 20 years by registering the boiler on the manufacturer's website and receiving a written 20-year warranty on the boiler.

To ensure the most economical operation of the induction boiler, it is best to combine it with a buffer tank, storage tank, along with the electrical connection working in the night tariff (G12) time. If it is not required by other heat sources, it is recommended to use a buffer without coils. Through a buffer tank, accumulation tank, we understand an insulated container, which is designed to accumulate thermal energy produced by the boiler and transfer this energy to the installation when the boiler is not operating. During the boiler operation, the circulation pump constantly mixes the water in the buffer, drawing cold water from its lower part and supplying it with warm water from the top. For an average home, it is enough to mount an accumulator tank, buffer, with a capacity of approximately 700 - 800 liters. The dimensions of such buffers are so small that they can be installed in every boiler room.
If you are planning or already have a solar installation, you can completely or partially cover the demand for electricity. Such energy sent to the network can be used in 80% at any time and used for heating the house or hot utility water.
