Boilers

Boilers

If your home has hot water radiators in each room for heat, you have a boiler to heat the water. Like a furnace, the energy efficiency of a boiler is given as the Annual Fuel Utilization Efficiency (AFUE). Boilers manufactured since 1992 must have an AFUE of at least 80%. We offer a complete line of gas boilers starting at 80% AFUE and up.

NAVIEN CONDENSING TANKLESS COMBI-BOILERS

Navien combination boilers provide endless hot water, as well as whole house heating for small and large homes

Navien offers two premium combi-boiler series: NCB and NFC. Both are high efficiency and high capacity, with NFC having larger heating output.

NCB Series

NCB combi boilers offer homeowners higher turndown ratios, wider BTU ranges, longer venting for more flexible installation, an all-new easy-to-use multi-line LCD display with improved controls and intuitive navigation, and an upgraded domestic hot-water module.

NFC Series

NFC high-efficiency condensing fire tube combi-boilers offer all the features of our NCB series plus the highest heating and DHW performance ever built into one compact combi-boiler system.
