/ About the Pyroclast™

Reliable Heat Pump Technology Meets Revolutionary Thermal Storage

The Pyroclast™ Commercial Integrated Heat Pump Water Heater combines cutting-edge heat pump technology with revolutionary, non-oil-based Phase Change Material (PCM) thermal storage to deliver unmatched performance in commercial water heating. This integration not only maximizes energy efficiency but also drastically reduces installation time and the overall system footprint. With thermal storage that is four times denser than water, the Pyroclast™ offers the equivalent of 375 gallons of storage without requiring bulky tanks. 

Design and built in collaboration with Htec Packaged Systems, this innovative solution allows facility managers to reduce energy costs by over 60% when compared to traditional heating methods.

In addition to its energy efficiency, the Pyroclast™ is designed with ease of use and reliability in mind. Its compact, all-in-one design ensures seamless integration into new builds or retrofits, while its advanced heat pump system delivers consistent hot water in even the most demanding climates. Whether installed indoors or outdoors, the unit can handle a variety of environmental conditions, all while maintaining low global warming potential (GWP) and ensuring the lowest possible environmental impact.

The Pyroclast™ also incorporates multipurpose service valves, allowing for maintenance without interrupting hot water availability. This ensures that buildings continue to operate smoothly, with no downtime or service interruptions—a critical feature for hospitals, hotels, or multi-family residential complexes. Whether for new construction or retrofit projects, the Pyroclast™ offers a future-proof solution, reducing both upfront costs and long-term energy expenses, all while being incredibly simple to install.
