95+% Efficient
1. The quiet, brushless DC blower prepurges the submerged
combustion chamber for 8 seconds and turns off.
2. The hot surface igniter is energized and glows red hot.
3. The blower turns on, precisely mixing air and gas for combustion.
The mixture is forced through the metal fibre burner and is ignited
by the hot surface igniter. A blue flame is evenly distributed
across the entire burner, resulting in clean combustion with low
nitrous oxide emissions.
4. The combustion chamber wall transfers high temperature heat
from the flame to the water.
5. The blower pushes hot combustion gases through the spiral coil,
which scrubs the remaining heat from the hot gases.
6. As combustion gas exits the bottom of the spiral coil, it is barely
warm to the touch. Over 95% of the heat from the flame is
transferred to the water.
7. Combustion gases are vented through PVC, CPC or ABS plastic
pipe.

.
Condensation formed by cooled combustion air is captured by a
condensate trap and drained through a drain line.
The Quiet Way to
Efficiently
Heat Water
An ultra quiet radial blower is combined with a submerged burner for
whisper quiet operation. Indicator lights illuminate when the power is on
and when the igniter and burner are operating.
The Best Choice for
Hot Water
Polaris is ideal for large homes. For dishwashing,
showers, baths, clothes washing, or hot tubs, Polaris is
the best choice. Polaris models heat up to 257 GPH
at a 90PF temperature rise, compared to 41 GPH for
standard gas water heaters.
Polaris Combines Water Heating with Space Heating
Forced Air
Hydronic Heat
Polaris can be used to combine an air handler for comfortable
forced air hydronic space heating with potable hot water. Hot
water is circulated through a coil in the air handler. Air from
the home is warmed as it is blown across the coil. Warmed air
is returned to the home through air ducts. With up to 199,000
BTUs, Polaris can heat most homes, large or small.
Radiant Hydronic
Heat
Polaris works great for homeowners who prefer radiant
hydronic heat. With radiant floor hydronic systems,
potable hot water is circulated through tubes under the
floor. The floor absorbs heat from the tubes and radiates it
into the room. With radiant baseboard heat, potable
hot water is circulated through finned tube baseboard.
Heat rises from the baseboard heaters, warming the
home. All water components must be approved for
use with potable water.
