High-Efficiency Boiler Replacement and Installation
A high-efficiency condensing boiler can cut fuel use and save space over an old standard unit, which makes it worth considering at replacement time. We install and replace high-efficiency boilers throughout Bergen County, including Navien NCB, NHB, NFC and NFB systems.
Why We Recommend Navien for Boiler Replacement
We install and service every major boiler brand. However, we highly recommend Navien. Navien makes high efficiency condensing boilers, which pull extra heat out of the exhaust gas before it leaves your home. As a result, they use less fuel to make the same heat.
Here are the Navien boilers we install:
- NHB-H condensing heating boiler. A high efficiency boiler for hot water heating, with an AFUE of up to 95%.
- NCB-H and NFC-H combi boilers. One unit heats your home and makes your hot water, so you do not need a separate water heater.
- NFB-H fire tube heating boiler. A condensing boiler for hot water heating systems.
- NFB-C and NFB700-C commercial boilers. Condensing boilers for larger buildings and commercial heating.
Not sure which one fits? Our plumber will look at your home, your heating system and your hot water needs. Then we explain your options. You can also see the full lineup on the Navien website.
