Energy Savings
The ECO*PAK MBS also provides environmental benefits through energy savings
- The boilers have a 96% AFUE rating
- In low temperature radiant applications, ECO*PAK MBS units can achieve efficiencies in excess of 98%


The ECO*PAK MBS uses a proprietary gas saving controls algorithm, that leverages variable speed technology. This control system provides the efficiency benefits of a condensing boiler, combined with low turndown capacities to provide industry-leading flexibility of operation.
The ECO*PAK MBS is an all-variable-speed solution that greatly extends equipment life and improves efficiency.
Potential Annual Energy Savings
The Potential Annual Energy Savings table shows the annual energy savings of the ECO*PAK MBS™ in comparison to a less efficient system. For example, if the existing boiler system has an AFUE rating of 80% (top row), then the potential annual energy savings of the ECO*PAK MBS™, will be 41% as seen in the bottom row for the same column.
