  • Summary
  • Applications

    Multi-unit residential heating

  • Description

    The Armstrong Modular Boiler Systems (MBS) are fully integrated heating units combining the best in condensing-boiler and pumping technology for superior system energy performance. MBS modular elements can be easily maneuvered through tight spaces/doorways and quickly assembled once in place. The modular design and demand-based control allow for accommodating varying seasonal heating loads as well as changes in overall heating capacity.

  • Configuration

    Controlled through embedded Sensorless technology or in conjunction with a building automation system (BAS)

Lowest installed cost

  • Factory-designed, built and tested boiler units for fast and easy installation and up to 25% lower cost at commissioning compared to equivalent separate component supply installation
  • Plug-and-play connectivity for fast and foolproof installation
