Beacon-Morris 55K84 TWIN-FLO III Hydronic Kickspace Heater – Compact Hydronic Heating for Tight-Space Applications
The Beacon-Morris TWIN-FLO III is a hydronic kickspace heater engineered for supplemental heating in confined spaces where traditional baseboard or panel radiators are impractical. Designed for concealed installation beneath cabinets, in recessed wall enclosures, or other low-clearance areas, it provides an effective solution for heating small, enclosed zones without disrupting usable space.
This model operates by drawing heat from a hot water supply and distributing it through a fan-assisted convector core. With a heating range from 3,370 to 10,360 BTU/hr, it delivers variable output based on water temperature and flow rate, making it suitable for integration into hydronic systems with zone control.
Common Applications:
Under-cabinet installations in kitchens and bathrooms
Hallways and entry vestibules
Laundry rooms, mudrooms, and enclosed porches
Residential additions where ducted supply is limited

Installation Notes:
Installation is best performed by a licensed contractor familiar with hydronic systems and electrical hookups. The TWIN-FLO III requires connection to a hot water loop and a 115V power source. Proper placement relative to cabinetry and airflow clearance is critical for safe and effective operation. Verify compatibility with system design pressure and temperature requirements.
