Caldaria Condensing+

Benefits

  • Efficient, safe and flexible.
    A complete range of condensing boilers for outdoor installation.
    • High efficiency rating and reduction of energy consumption (ErP Class: A).
    • Wall-hung, suitable for outdoor installation.
    • Easy to install: boilers are equipped with high pressure water pump, expansion tank, safety valve and pressure gauge.
    • Safety valve outlet and condensate drain outlet, ducted separately.
    • High pressure pumps for systems with heat exchanger and/or water/glycol mix.
  • Easy installation.
    Outdoor wall hung installation, no occupation of thechnical rooms or ground space.
  • -25 °C operation.
    Down to -25 °C outdoor temperature operation (equipped with antifreeze system).
  • Totally modulating.
    A range of 3 units with different power; single unit power modulation 1:9 (1:18 for 100.2).
  • Modular and cascade.
    They can be managed in cascade, up to 8 boilers. Maximum system power up to 800 kW.
  • Domestic hot water.
    Management of a 3-way DHW diverting valve and DHW buffer tank probe. Centralized management of secondary circuit, DHW (through 3-way valve or dedicated delivery) and DHW recirculation circuits.
  • Multiple control choice.
    Manageable with single remote control, cascade control or via ModBus.
  • Wide pipe section heat exchanger.
    Caldaria Condensing+ boilers feature high quality heat exchanger.
    • Single circuit: no risk of overheating.
