Efficient Power, Sized to Your Vision

The XLF features integral HeatNet® control that can act as a boiler management system, networking up to sixteen units without requiring any external control panel. Such advanced performance in such a small space can benefit older boiler systems by adding contemporary efficiency for either heating systems or domestic hot water. For new construction, XLF makes possible a modular configuration that is unmatched for output relative to size. It can even be networked with other boiler types, including condensing units: adding XLF to a condensing installation can reduce the number of condensing units required to meet load during peak heating months, when condensing units' efficiency drops.

This application, called base loading or front-end loading, can significantly reduce first costs without compromising fuel efficiency.
