Heat Recovery Systems
Economizers, heat pump integration and skid-mounted rooftop platforms that recapture exhaust energy already leaving the building.

Codes and listings
- ASME
- ASHRAE 90.1
- Title 24
- UL 508A controls
The energy leaving a boiler stack has already been paid for. Recovery systems capture it before it clears the roof and put it back into hot water, hydronic heat, or a process loop.
Modular economizers capture thermal energy from boiler, furnace, and prime power exhaust in condensing and non-condensing configurations up to 3,200 boiler horsepower, with an integrated automatic bypass that adapts to swinging thermal loads. Actively condensing exhaust moisture also eliminates the visible vapor plume, which matters on cold-weather microclimates and architecturally sensitive rooftops.
Where a project is targeting electrification, exhaust recovery pairs with industrial air-to-water or water-to-water heat pumps. Using low-grade exhaust energy as the thermal baseline instead of ambient outdoor air produces a materially higher coefficient of performance for domestic hot water, hydronic heating, and process loops, and a predictable year-round yield.
For occupied facilities that cannot take downtime, skid-mounted rooftop platforms consolidate heat exchangers, circulation pumps, modulating bypass dampers, exhaust fans, and controls onto one structural skid. Pre-piped, pre-wired, and factory-commissioned, they drop into an existing exhaust run with under 30 minutes of operational interruption.

Heat Recovery Systems, answered plainly.
- How large a plant can an exhaust economizer serve?
- Platforms are engineered for commercial and industrial configurations up to 3,200 boiler horsepower, in both condensing and non-condensing service.
- Why pair heat recovery with a heat pump?
- A heat pump drawing on low-grade exhaust heat instead of ambient air runs at a much higher coefficient of performance, which is what makes fully electrified hot water and hydronic heating economical.
- How much downtime does a skid-mounted platform require?
- Because the skid ships pre-piped, pre-wired, and factory-programmed, field integration into an existing exhaust run is typically under 30 minutes of operational interruption.
