HL / HLE Series Large Hydronic Heater - 6,700 to 27,250 BTU
King’s HL HLE Series large hydronic heater uses the energy from a building’s existing hot water source to offer
efficient, whisper quiet operation and the ability to reduce utility bills with individual room control. By installing hydronic heaters in
every room, you can easily heat only the areas in use and conserve energy. Designed to fit neatly between standard wall studs,
this in-wall heater provides out of the way positioning ideal for use in public areas, corridors, entry ways and large rooms or
hallways. For use in both residential and commercial applications. Provides 6700 to 27,250 BTU heat output. Recommended 17
BTU per square foot for new construction.

Motor: 2 speed shaded pole impedance protected. Permanently lubricated. Bronze
bearings.
Blower: Tangential blower to provide 150 to 375 CFM of air. Quiet operation of
less than 53 dBA weighted scale at high speed. Easily removed for service. Bronze,
not plastic, bearings.
Coils: 1/2" ID Copper tubes with Aluminum fins of no more than 4 fins per inch for
free flow of air and maximum circulation of air and water. Tested at 300 PSI for
leaks. Bleed valve to purge air. Copper tube used in coils is Alloy 122 made to
ASTM B-75 specifications.
Grill: 20 gauge mild Steel, louvered with Nickel-plated grille screws.
Powder-coated in white.
Wall Can: 20 gauge mild Steel, electrogalvanized to resist corrosion. 1/2" knockout
in bottom of can and QuickSet
™
bend out mounting tabs for fast installation.
Fan Switch: 3 position fan switch High / Off / Low. Rated at 10 Amps with wire
leads and insulated ¼" quick connects.
Terminal Board: All electrical connections will terminate at a phenolic terminal
board with ¼" male brass blades for easy wiring.
Water Connections: 1/2" bare Copper tubes de-burred. Tested at 300 PSI for
leaks. Clean out tubes for water connection.
ECM Motor: We program the motor to start at slowly and quietly at 50% of its
maximum speed. Over a 3 to 5 minute period, if the room is not reaching the
set point it will slowly ramp up to 100% airflow to heat the room. It not only
saves energy but also makes a large output heater have a soft quiet start, yet
can increase to its maximum output and sound level over time while not
disturbing residents.
