FI-B - Boiler

General issues

- the boiler is a tank with the capacity defined in its name and it has inside a cooling coil.
- Boilers accumulate heat in time and transfer it upon request. In this case the equipment operates in accumulation regime. Yet, if hot water is used, the boiler operates as a continuous flow heat exchanger.
- FI-B boilers are assembled on the floor, in a vertical position and they are equipped with threaded connections to be connected to the source of heat agent production ands to the consumers.
- the tank is made up of high quality steel sheet of 4, 5, 6 or 8 mm thick (thickness according to the size of the tank), they have cylindrical shape and with curved and enamel coated covers according to DIN 4753 which are coated on the interior with a special enamel approved by the Ministry of Health.
- the heat exchanger is made up of one or two helicoids coils depending on the construction option, made of copper pipe.
- the hot water in the boiler design for consumption is heated by: connecting this boiler to a different boiler or to a heating plant and the primary heat agent supplied by the boiler and passing through the coil transfers heat to the household hot water; when connecting the boiler coil to a system of solar panel; or with electrical resistance with thermostat control (the range 100 L – 1000 L);
- the boiler can be optionally equipped with: thermo manometer, electrical resistance (the range 100 L – 1000 L equipped with connection socket), magnesium anode, immersion thermostat for the circulation pump control, safety valve.
- heat insulation made up of mineral wool mattresses over which a protection cover with zipper is assembled.



Benefits

- long life due to the solid construction and the quality materials used.
- the main advantage of the FI-B boilers is the large quantity of prepared hot water at constant temperature and the equal flow for each consumer.
- the boilers with bivalent accumulation (with two coils) are designed to cope with a significant consumption of hot water in a short term , the energy is accumulated from two sources of heat, thus obtaining higher output.
