How does King’s hydronic system work?
The concept is simple: Redirect existing hot water rather than expend energy to
create a new heat source. King’s hydronic heating system uses hot water from your
hot water tank (any hot water source — gas, electric, solar, etc.), passes it through
highly efficient radiant heat plates, and returns the hot water to your tank. Inside the
heater, a gentle fan draws room-temperature air across the radiant plates where the
air is warmed before being pushed back out into the room. But the real magic is in
our thermostat system, which maintains consistent individual room temperatures
while using the smallest amount of energy possible.
How does King’s ECM fan and thermostat work together?
The King HW system-matched thermostat has two steps. The first makes sure hot water is moving over the
radiant plates, and the second activates the quiet, low-RPM fan once the radiant plates are up to
temperature. The energy-saving ECM (electrically commutated motor) version has a progressive RPM
which, in conjunction with the thermostat, adjusts airflow only as much as is needed to maintain room
temperature. The HW thermostat controls the room temperature as accurately as
+
/- one degree (compared
to
+
/- five degrees of other hydronic systems). Energy is saved because the unit begins heating when room
temperature drops slightly, and runs briefly, just enough to bring the room back to temperature.

Why King’s hydronic system makes sense today:
• Utilizes a hot water system already in place • Minimal components to install, uses flexible hot-water lines
• Minimal floor space used — no furnace footprint • Maximized energy savings with ECM fan and two-step thermostat
• Single room temperature control lowers cost • Near-silent operation, smooth, consistent, comfortable room heat
• Less temperature fluctuation than typical systems • High-quality, American-made constuction means low maintenance
• Easier to install than forced air ducting • Works with typical hot water energy source: gas, electric, solar, etc.
