Steel hot water boilers CentroPlus-B (nominal heat output of 25 and 35 kW) have two separate combustion chambers inside the common water chamber with an stainless steel domestic hot water heater submerged inside the boiler`s water chamber.

The left combustion chamber is used for solid and liquid fuel firing. The right combustion chamber is used for pellets and liquid fuel firing. The possibility of combined firing and the automatic start-up of the oil and pellets burner, in the moment when the solid firing does not meet needs any more, make this boiler extremely interesting.

Other special feature, which makes CentroPlus-B even more interesting, is the submerged stainless steel domestic hot water heater, which provides a constant temperature level of domestic water without additional investments.

Successful application of modern technologies and high quality building materials as well as double-checked technical solutions, make these boilers safe, reliable and easy to assemble. The boilers are produced in compliance with the European norm EN 304 and EN 303-5.

Characteristics of CentroPlus-B boilers:

- Hot water boiler for central heating systems is produced for all kinds of fuel (solid and liquid, solid and pellets, liquid and pellets) and has a nominal heat output of 25 and 35 kW.

- Possibility of interchangeable use of combustion chambers.Only one flue exhaust connection.

- Possibility of connecting thermal safety unit onto prepared openings.

- The body of the boiler is delivered separately from the casing with thermal insulation, oil burner and pellet set.

- This enables uncomplicated transport and reduces the damaging risk to the minimum.

- Special distinction is its extraordinary thermal and acoustic insulation.

- Among all above mention characteristics, the CentroPlus-B boiler has a built-in stainless steel water heater, which does not require a separate circulation pump. This would be necessary if the water heater would be separated from the boiler.

- The boiler is tested and certified according to the European norm EN 303-5 and EN 304 at the Faculty of Engineering in Zagreb. Production in compliance with ISO 9001/2000 norm.

Solid fuel / liquid fuel combustion chamber:
Accordingly dimensioned combustion chamber, 3-passes flue gas flow and additional ribbed surface for temperature exchange assure a high efficiency operating rate of the boiler, which makes it very “economical”. It is ecologically acceptable, which has been proved by very demanding certificate of the Austrian County Styria (FanIG). The big combustion chamber door enables firing with big peaces of wood, as well as its easy cleaning and maintenance.

Liquid fuel / pellet combustion chamber:
Accordingly dimensioned combustion chamber assures a high efficiency operating rate of the boiler, which makes it very “economical”. The big quantity of water inside the boiler reduces the number of firings, prolongs its life and saves energy. The boiler door is prepared for connection of the pellet/oil burner.

Additional equipment:
Safety valve (6 bar), expansion vessel, check valve for domestic hot water are obligatory.It is also recommended a pressure regulator, 3-passes thermal valve for domestic hot water.
