Boiler with two fireboxes – Centrometal CentroPlus / CentroPlus-B

Steel hot water boilers CentroPlus and CentroPlus-B with nominal heat output of 25, 35 and 49 kW have two separate furnaces in common boiler water. The left firebox is used for heating with solid or liquid fuel, and the right for heating with pellets or liquid fuel. The possibility of combining solid fuel heating and automatic switching on of the oil or pellet burner at the moment when the solid fuel does not meet the need for heat, makes this boiler especially interesting. A special feature of CentroPlus-B boilers is the built-in stainless steel boiler for domestic hot water dissolved in the boiler water, which makes it extremely interesting, because it ensures constant heating of hot water in the boiler without additional investment. The successful combination of modern technologies and quality building materials with proven technical solutions give the boilers safety and reliability in operation with ease of installation and use. They are made in accordance with the European standard EN 304 and EN 303-5.

Basic characteristics of CentroPlus i CentroPlus-B:

• CentroPlus hot water boiler intended for central heating intended for heating with solid fuel, solid and liquid fuel, with solid fuel and pellets and liquid fuel and pellets, rated heat output of 25, 35 and 49 kW
• Possibility of alternating use of both fireboxes
• Only one flue connection
• Possibility of installing thermal safety on factory-prepared openings
• A separate boiler body, separate formwork with thermal insulation and a separate oil or pellet set are supplied, which enables easy transport and installation and reduces the risk of damage.
  Delivery content:
  – boiler body with boiler door on a wooden pallet (with flap for the left hearth door, flap of the right hearth register, ashtrays, grate of the left and right firebox and turbulators);
  – cardboard box with boiler casing, thermal insulation, thermometer, draft regulator (as CALEFFI 529 500 or ESBE C 20/25), rear ash box, cleaning accessories (accessory holder, brush, rake and poker), protective box for extension for pellet burner and set with screws and snaps
• A special feature is the exceptional thermal and sound insulation
• A special feature is the exceptional thermal and sound insulation
• The boiler was tested and certified according to the European standard EN 303-5 and EN 304 at the Faculty of Mechanical Engineering and Naval Architecture in Zagreb and manufactured in accordance with the standard ISO 9001: 2008

Solid fuel / liquid fuel firebox:

• Appropriately dimensioned combustion chamber and combustion of combustion gases in three passages ensure a high degree of boiler efficiency, which makes it “economical”
• The large door and the firebox of the boiler enable heating with large solid fuel and easy cleaning and maintenance

Liquid fuel / pellet furnace:

• Properly dimensioned firebox with turbulators ensures a high degree of efficiency of the boiler, which makes it “economical”
• The high water content in the boiler reduces the number of starts and prolongs the life of the burner and saves energy
• The boiler door is prepared for the installation of a pellet / oil burner
