flexibility. They can be installed in a closet, garage, pantry or laundry room without consuming valuable

floor space. Outdoor installation is easy with the available recess box and hard-wired, remote
temperature controls. True workhorses, EverHot water heaters were designed to handle multiple,
simultaneous hot water draws. EverHot water heaters feature a modulating burner system with inputs
A
A
ranging from 15,000 to 199,000 BTU’s.
Important reasons to consider a Laars® EverHot ®
Tankless Water Heater for your next installation.
Save Money and Energy
EverHot units only run when there’s a call for hot water.
When the tap is opened, the energy efficient heating
process quickly raises water to the desired temperature.
When the tap is closed, the water heater simply shuts off,
thereby saving energy.
Save Space
The small overall size of EverHot water heaters allows
them to be tucked away in a closet, a utility room or any
convenient corner. And, since they are a wall-hung unit,
floor space isn’t an issue.
Application Flexibility
When the demand calls for it, EverHot water heaters can
be manifolded together or spaced strategically throughout
a home or business. They can also be used in tandem with
a storage tank for filling a hot tub or any other volume
water circumstance.
Multiple Points of Use
Don’t let the small size fool you. Both residential and
commercial models can handle applications where multiple
hot water draws are common.
Remote Controller Convenience
Indoor models have a primary control integrated into the
face of the water heater. Outdoor models are shipped with
a separate primary remote controller. Residential indoor
and outdoor models can have two additional remote
controllers hardwired at multiple use locations. Commercial
models may have only one remote controller.
Installation Options
EverHot models can be installed indoors or out, on the roof
or in the basement. The direct venting design of indoor
models allows for vertical or horizontal vent runs with or
without multiple bends.
Intelligent Design
EverHot tankless water heaters self-modulate gas flow
requirements, self-monitor outflow temperature and selfdiagnose any rare malfunction in the water heating
system.
Continuous Flow
A super-efficient, nine pass heat exchanger and selfregulating inputs of up to 180,000 BTU’s for indoor
models and 199,000 BTU’s for outdoor models ensure a
continuous flow of hot water.
Residential Models
• Continuous Flow—Supplies hot water continuously at
the temperature set point.
• Heat Exchanger—Nine pass design to maximize heat transfer
and efficiency.
• Remote Control—Interior models have a primary control
integrated into the face of the water heater. Exterior models
are shipped with a primary remote controller. For both interior
and exterior models up to two controllers can be hardwired at
multiple locations. Provides 96˚-160˚F. Optional controls
provide 96˚ -120˚F setting.
• Direct Electronic Ignition—No standing pilot.
• Very Low Noise Level—49dB.
• Fully Automatic Controls—Outgoing water temperature is
monitored by a built-in sensor. Burner and combustion blower
modulate between minimum and maximum input to maintain
setpoint temperature. If the temperature of the water exceeds 6
degrees above the set point temperature the burner will shut
down. The burner will ignite once outgoing water temperature
falls below the set point.
Commercial Models
• Interior and Exterior Models—Self regulating inputs, Interior
Models=15,000-180,000 BTU's, Exterior Models=15,000199,000 BTU's.
• Diagnostic Controls—Error messages in numerical
codes are displayed on primary control.
• Cut Energy Waste—Appliance runs only when there is a
demand for hot water.
• Space Saving Installation—Compact size for tight installations
(mounts on the wall).

• Lime Accumulation Sensor—Built into heat exchanger, alerts
of build-up.
• Direct Electronic Ignition—No standing pilot.
• Venting (interior model)—Can be vented horizontally through
a wall or vertically through the roof. Maximum equivalent vent
length is 41 ft. Vertical venting maximum height is limited to

monitored by a built-in sensor. Burner and combustion blower
modulate between minimum and maximum input to maintain
setpoint temperature. If the temperature of the water exceeds 6
degrees above the set point temperature the burner will shut
down. The burner will ignite once outgoing water temperature
falls below the set point.
• Ten year limited warranty on heat exchanger.
• Interior and Exterior Models—Self regulating inputs, Interior
Models=15,000-180,000 BTU's, Exterior Models=15,000199,000 BTU's.
• Diagnostic Controls—Error messages in numerical codes are
displayed on primary control.
• Cut Energy Waste—Appliance runs only when there is a
demand for hot water.
• Space Saving Installation—Compact size for tight installations
(mounts on the wall).
• Lime Accumulation Sensor—Built into heat exchanger, alerts
of build-up.
• Very Low Noise Level—49dB.
• Five year limited warranty on parts.
• Venting (interior model)—Can be vented horizontally through
a wall or vertically through the roof. Maximum equivalent vent
length is 41 ft. Vertical venting maximum height is limited to
21 ft. Maximum of 3 elbows (vertical and horizontal). Interior
models have dedicated venting system components that must
be ordered separately.
• Five year limited warranty on heat exchanger.

• The maximum equivalent length of the vent/air intake system is 41 feet.
Maximum overall height is limited to 21 feet. For vertical vent heights over
five feet, an approved condensate collector must be used. A 45° elbow
equals 1.5 feet of vent/air intake run. A 90° elbow equals 6 feet of
vent/air intake run.

• No additional venting accessories are required for outside wall
installations.
• Indoor installations require 3" exhaust air pipe inside 5" concentric air
intake pipe (only one hole to cut in wall or roof).
Data shown in chart and table is based on indoor models.
Flow rates for outdoor models are slightly higher.
Meets the low NOx emission requirements for water heaters.
