A Navien combi boiler heats your home and your water in one compact, high-efficiency unit. You get steady heat, endless hot water, and no separate hot water tank taking up space. RI Pipe Guys installs Navien combi boilers for homeowners in Warwick, Cranston and throughout Rhode Island.
We install natural gas and propane Navien combi boilers, and we can replace an older boiler and hot water tank with a single combi unit. We can also convert oil heat to gas or propane. Removal and disposal of your old equipment is included. Warranties vary by brand and part, and the manufacturer's warranty applies.
