Navien NCB-E is the first high efficiency condensing combination boiler with the capacity to supply both heat and domestic hot water for larger homes — enough hydronic heat for a whole house, plus hot water to run two showers and a dishwasher all at the same time.

The Navien NCB-E saves installation time and reduces call backs. In addition, the NCB-E takes up 80% less space than a traditional floor standing boiler and tank water heater. Your customer now has more room, saves energy and enjoys all the hot water they need, whenever they want it.

Advantages

dual-input

Dual inputs of up to 120k BTU/H for heating and 199k BTU/H for DHW
Supplies all the heat and domestic hot water that most houses require.

PVC Ventingpvc-venting

Low exhaust gas temperatures allow use of PVC, CPVC, ULC S636 and polypropylene vent systems, reducing installation time and costs. The system can use 2″ venting for up to 60′, or up to 150′ with 3″ venting.

4.5 GPM@77° temperature rise for domestic hot watergpm

Separate stainless steel flat plate heat exchanger for DHW creates the highest flow rate for any combi boiler in the industry.

Low gas pressure operationlow-gas-pressure

Our negative pressure gas valve ensures maximum performance all the way down to the minimum gas pressure of 3.5″ of the water column.

Turn down ratio of 6:1 for heating and 11:1 for DHWratio
The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive boiler cycling and enhances temperature control for DHW.

 

Uses existing ½” gas piping

We are so happy with the service, support and product that we received from Cozy Comfort Plus. Brian was incredible to work with, he took the time to understand what we were looking for and helped us with the designs and what the best fireplace for us might be. He is extremely easy to work with, very easy to communicate with and so fast and responsive!

Everything happened exactly on schedule and as planned. It was a well oiled machine!! The crews that were here to build everything were super friendly, kind, courteous and knowledgeable.

Highly highly recommend to all 😀👍

Brian once again helped me with my project. Before I have installed a gas fireplace and this time I have installed an LG heat pump with 3 indoor heads. We had an amazing experience with Brian and his team for both projects from quote to installation. Brian is experienced, patient, reliable, and provides great friendly service. He’s also tells very interesting life stories which makes enhances the whole experience. All my future business is going to his company. Thanks again Brian!

From installation to maintenance, Cozy Comfort Plus Inc. provided us with prompt, quality service. It took under a day to install our Mitsubishi split-type air conditioner in May, 2021. This week, they attended to cleaning our unit’s filters in less than a day’s notice. The technician explained how to remove, clean and reinstall the filters ourselves which will save us money down the road. I highly recommend Cozy Comfort without reservation.
