Steel hot water boilers CentroMini (nominal heat output 14 kW) are engineered for solid fuel, oil/gas or bio-mass (pellets) firing. They are used for heating in smaller premises as a primary or, nowadays, very frequently used as an alternative heat source.

Boilers can be easily recognized by the successful synthesis of modern technologies and by the high quality of material they are made of, as well as through their simple and easy assemblage and control. The wide application of double-checked technical solutions make these boilers safe and reliable. Their special distinction is the possibility of a simple connection to the burner, as well as the functioning through fully automatic process of heating with oil/gas fired burner and bio-mass firing plant.Produced in compliance with the European norm EN303-5.

Characteristics of CentroMini boilers:
- Hot water boiler for central heating systems is produced for solid fuel, oil/gas, or bio-mass (pellets)firing (nominal heat output 14 kW).

- Accordingly dimensioned combustion chamber assure a high performance of the boiler with high efficiency rate. This makes it very "economical".

- Ecologically acceptable.

- The combustion chamber is made out of high quality 5mm thick steel sheet.
- The big door enables firing with big peaces of wood, as well as easy cleaning and maintainance.

- If required a termical safety system can be built in through already prepared holes.

- The thermostat for pump steering is built in.

- The body of the boiler is delivered separately from the casing with thermal insulation which enables easier transportation and assemblage without unnecessary risks.

- For an easy and simple casing assemblage no screws necessary.

- Basic delivery includes the thermometer for the water temperature as well as cleaning accessories and ashtray.

- For the oil/gas firing burner application the lower door of the boiler has already prepared assemblage holes.

- In case of bio-mass (pellets) firing, a lower door bound to the connection of the burner as well as the dosing plant shall be delivered as a part of additional equipment.

- The basic regulation of the burner (oil/gas) is delivered additionally and is to be connected on already prepared place situated on the upper casing lid.

- 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.

Hot water supply demands:
In order to meet this requirement, the boiler CentroMini can be connected to one of our hot water heaters. Therefore we suggest the combination with hanging hot water heaters SKB Digi or LKB Digi , with standing hot water heaters TB (120 - 200 l) and TB (300 - 800 l) or with solar hot water heaters STEB, as well as with combined hot water heaters CAS-BS, if there is a need to build in a solar heating system in the future.

Additional equipment:
Obligatory (solid fuel firing) - draught regulator, manual 4-way mixing valve if the boiler connected to the closed central heating system - thermal safety valve, heat exchanger, safety-air vent group (2,5 bar) and expansion vessel .
Obligatory (pellet firing) - Cm Pelet-set, if the boiler connected to the closed central heating system - thermal safety valve, heat exchanger, safety-air vent group and expansion vessel.
Obligatory (oil/gas firing) - boiler regulation for boiler EKO-CK, oil/gas burner, if the boiler connected to the closed central heating system-safety-air vent group and expansion vessel.
