- Navien America's Condensing Combination Gas Boiler is the ideal
- solution for customers who need both domestic hot water as well
- as a space heating application. Unlike conventional boilers,
- Navien America's Combination Gas Boiler heats water only
- when needed, making it environmentally sound as well as cost
- efficient.
Superb Condensing Efficiency & Easy Installation
- Navien's Condensing Combination Gas Boiler is equipped with dual
- stainless steel heat exchangers, making it efficient and economical.
Extended Life, Stainless Steel Heat Exchanger
- Stainless steel for the Combi's integrated primary and secondary
- heat exchangers prevents corrosion and ensures a longer
- lifespan over copper heat exchangers.
Stainless steel components also maintain consistency, - even during long periods of use, and aid in eciency by
- capturing as much condensation as possible.
Eco-Friendly, Eco Pre-mixed Burner
- High grade stainless steel burner uses pre-mixed air and
- gas ratio providng a 10% to 100% firing rate.
The Eco Pre-mixed Burner generates at least 20% less - CO and about 75% less harmful air pollutants such as
- NOx than other conventional water heaters.
Advanced Safety Operation, Gas-Air Ratio Control
- Navien's Gas-Air Ratio Control (GARC) System highly
- advance control system modulates both the air and gas ratios
- required for optimal combustion.
- The ingenious built-in CO monitoring system will shut the
- Combi unit down in the event of excessive CO gases build up
- and cause a hazardous condition.
Auto Sensing & Adaptive Heating, ASA Control System
- The Combi's ASA Control System maintains a consistent,
- comfortable temperature throughout the home at all times,
- even taking into account the home's design and outside
- temperature.
The secret to this system involves a built-in thermostat which - senses even the slightest temperature changes. The Combi's
- space-heating application calculates the amount of heat required
- based on the difference between the return-water temperature
- and the indoor temperature, then automatically adjusts and
- controls the temperature accordingly.
Weather Compensation Heating, K-Factor Heating
- An outdoor sensor can be connected to Navien's Condensing
- Combi Water Heater. With this device the unit can automatically
- regulate the heating temperature according to changes in the
- temperature outdoors, allowing for precise indoor heat regardless
- of what the weather is doing outside.
Automatic Water Filling System
- Navien's Condensing Combination Gas Boiler automatically fills
- water into space heating pipes when the unit senses water
- shortage in pipes.
Powerful Anti-Freeze Feature
- The Combi's built in electrical system is designed to keep the
- unit's plumbing frost free in winter conditions.
Intelligent Remote Control System (include in every unit)
- Aesthetic Appearance Suitable for Any Household's interior Design
- High-Precision Water Temperature Control in 1℉ Increments
- 24 Hour Time Scheduling for Space Heating
- Easy-to-Use Button Type Control
