Pride Plumbing came out and provided a cost estimate to replace a malfunctioning Rinnai RUR98i water heater with a new Navien 180A or 240A tankless model with a NAVICIRC recirculation pump. This would include: 1) removing and disposing of the old water heater along with its electrical wiring, venting, and gas and water supply lines; 2) installing the new tankless unit along with its service valves, PEX and stainless steel water lines to the unit's water connections, copper gas supply line, gas regulator, NAVICIRC recirculating kit, drip leg, gas shutoff valve, and condensation and intake lines; 3) wiring up the unit; 4) ensuring that it was properly vented; and 5) lighting and programming the unit.
