KD Navien was the first Korean company to adopt the EN
(European) standard for all its boilers. This assures world class
quality in every country where our products are sold.
Today KD Navien retains the largest market share for boilers in
South Korea. As a leading boilermaker, the largest exporter of
boilers from Korea, KD Navien proudly exports that leadership in
dependability, design, green technology, social responsibility and
customer service to over 30 countries.
Everyone said it would be extremely difficult to export boiler
equipment to the United States. KD Navien pushed its way forward.
Since the foundation of its local subsidiary in the US in 2006, it
has targeted the North American market. As a result, it became one
of the top three companies for instanta-neous gas water heaters in
two years, and has taken the largest market share of instantaneous
condensing gas water heaters on the market.

Low exhaust gas temperature allows use of PVC, CPVC and
polypropylene vent systems, reducing installation time and costs.
System can use ø60mm venting for up to 20m, or up to 45m with ø75mm
venting.
Our negative pressure gas valve ensures maximum performance all
the way down to a minimum gas pressure of 8.7mbar.
The sophisticated gas flow control system provides a high turn
down ratio, reducing energy waste and excessive boiler cycling and
enhances tempera-ture control for DHW.
Low NOx high efficient pre-mix-ture combustion system allows
easy field convertibility from NG to LP operation. Orifice for LP
conversion included.
For extraordinarily large domestic hot water demand, the NCB can
be cascaded with our NPE water heaters.
Save time and effort in retrofit application with 15mm gas lines
for up to 7 meter.

What is Navien Wireless Zone Control System?
Navien’s Wireless Zone Control System is a system that can be
easily set up at existing houses or renovated apartments without
electric wiring work. Navien’s Wireless Zone Control System is
installed with the wiring of existing boilers, room thermostats and
the rest by using RF(wireless) technology, making the whole
installation convenient. This installation can be applied.
If you choose Navien boiler, an ideal heating can be realized
with DHW temperature control and energy saving.

NAVIEN micro-CHP
EXCELLENT
SAVINGS BASED ONULTRA EFFICIENCYHeat + Electricity
ENERGY AND COST
Why Navien HYBRIGEN?
m-CHP is technology that simultaneously generates electricity,
while providing heat and hot water by burning fuel such as natural
gas.
There are many versions of m-CHP available today: stirling
engine type (external combustion engine), gas engine type (internal
combustion engine) and the fuel cell type (PEMFC, SOFC and
etc.).
Navien HYBRIGEN Stirling Engine
Navien HYBRIGEN SE provides an innovative solution to the global
power supply crisis.This is the next generation green technology
capable of resolving the global power supply crisis, while reducing
fossil fuel consumption and greenhouse gas emissions!
Navien HYBRIGEN SE is m-CHP for home use that produces
electricity by driving a stirling engine. The heat generated in the
process is used for heating and domestic hot water.
When the space, which contains the piston and cylinder �lled
with Helium gas, is heated by a burner, the piston goes down as the
volume of the Helium gas expands. In turn, the piston goes up when
the volume of the Helium gas is compressed as it is cooled by
coolant. Through the repeated up and down of the piston, an induced
current is generated in the linear generator located inside the
engine, producing electricity.
The stirling engine is one of the leading external combustion
engines in the world. Unlike an internal combustion engine, a
stirling engine produces much less noise, vibration, and toxic
emissions.Since stirling engine has a simple engine structure, it
is extremely durable and does not require excessive
maintenance.
How does it work?
Heating
Down Up
CoolingStirling Engine
47
m-CHP
SE
For heatingWhen heat is applied to the engine from outside, the
Helium gas inside the cylinder expands and pushes the piston.
For coolingWhen the expanded Helium gas is cooled, the gas is
compressed and the piston is pulled back.

Navien HYBRIGEN SE primarily consists of a stirling engine and a
condensing boiler.The stirling engine section is made up of an
engine burner for combustion, an engine heat exchanger, a piston
for generation and a generator. This section is involved in power
generation.The high temperature exhaust gas generated in the
combustion process, is used not only for heating and hot water but
also for driving the stirling engine. Navien’s innovative
condensing technologies contribute to high fuel e�ciencies.
In addition, our optimized control system maximizes the
generation e�ciency and minimizes the energy costs.

Signi�cant reduction of energy costs
Easy to use to replace an existing gas boiler thanks to similar
installation environment, which also facilitates maintenance.
Easy to install in the average home thanks to its smaller size
when compared to other fuel-cell based m-CHP products.

Appropriate for home use as it generates low noise and vibration
and features a simple structure, which ensures excellent
durability.

About 47% of solar thermal is accumulated on ground surface,
maintaining the temperature under the surface as 15˚C
Geothermal system uses this heat source for running heat pump,
providing heating and cooling
Mechanism of geothermal energy
Cooling modeRadiate heat to the ground in order to lower indoor
temperature by using Navien’s geothermal heat pump
Heating modeAbsorb heat from the ground in order to raise indoor
temperature by using Navien’s geothermal heat pump
