Description
Navien NCB-190/080H High-Efficiency Condensing Combi-Boiler
The Navien NCB-190/080H is a high-efficiency condensing combi-boiler designed to deliver powerful home heating and continuous on-demand hot water in one compact system. With 190,000 BTU/h dedicated to domestic hot water and 80,000 BTU/h for space heating, this model is ideal for small to mid-sized homes seeking superior comfort, high energy savings, and maximum space efficiency.
Offering up to 95% AFUE, the NCB-190/080H uses advanced condensing technology to capture and recycle heat that would normally be wasted. This significantly reduces fuel consumption and helps homeowners lower their monthly heating and hot water costs. Its sleek, wall-mounted design replaces both a traditional boiler and water heater—freeing up valuable space in mechanical rooms, basements, and utility closets.
Equipped with intelligent digital controls and a fully modulating burner, the unit automatically adjusts its heat output based on real-time demand. This ensures consistent indoor comfort, faster hot water delivery, and reduced energy waste. A heavy-duty stainless steel heat exchanger enhances durability, improves heat transfer efficiency, and provides long-lasting performance with minimal maintenance.
With ultra-low NOx emissions, the NCB-190/080H is also an environmentally friendly option that meets strict emission standards. Easy installation, flexible venting options, and built-in self-diagnostic features make it a convenient and reliable solution for homeowners and installers alike.
The Navien NCB-190/080H is an exceptional choice for those seeking a space-saving, energy-efficient system that delivers both reliable heating and continuous hot water—making it a smart long-term investment in home comfort and performance.

Reliable heating and steady hot water. Took a full day to install, but everything was tested before they left.
Carla Moretti –
Professional installation and clear instructions on usage. The boiler handles multiple showers without temperature drops
Daniel Petrov –
Jimmy HVAC installed the Navien NCB-190/080H in our 1900 sq. ft. home. No issues so far and heat recovery is quick.
Michelle Wong –
System works as expected, but follow-up response time could be better. Installation itself was done properly.
Kevin O’Neill –
Upgraded from an older boiler to this Navien combi unit. Saves space and performs well. Service was fast once scheduled.
Hassan Ali –
Heating is even across our two-storey home. Pricing wasn’t the cheapest quote, but the quality of work felt worth it.
Jennifer Lavoie –
Very happy with Jimmy HVAC. The install crew explained everything clearly and finished on time. Hot water supply is consistent.
Paul D’Souza –
The Navien NCB-190/080H works fine so far, but it took longer than expected to book the install. Product itself seems solid.
Trevor Bennett –
The combi boiler runs quietly and keeps the house warm. Took most of the day to install, but the technicians were respectful and cleaned up.
Amandeep Kaur –
Good system for our 1800 sq. ft. house. Installation went smoothly and pricing was reasonable compared to other HVAC companies.
Robert Sinclair –
Installed the Navien NCB-190/080H last month. Heating is steady and hot water is instant. Jimmy HVAC’s install team knew what they were doing.
