Water & Space Heating Units (Combi)

Combination boilers that provide both space heating and domestic hot water. The collection includes Noritz NRCB 180,000 Btu/h combi boilers in natural gas and propane and a 199,000 Btu/h natural gas model.

Confirm the fuel type, since models are specific to natural gas or propane. Size the unit for both the heating load and peak hot water demand, as hot water usually takes priority. Check venting options, gas line size, water quality and condensate drainage, and review the installation manual for piping requirements.
