NAVIEN certified and trained on every condensing model
Factory-trained installation, annual descaling, and error code diagnostics for the units Carlsbad homeowners actually run.
Jack's Plumbing and Heating has been a NAVIEN certified tankless water heater specialist in Carlsbad for over 35 years. That certification isn't a sticker on a truck. It means our plumbers completed factory training on NAVIEN's entire product line, from the NPE-2 condensing series to the NPN non-condensing units. We know these systems inside and out because tankless water heaters are our bread-and-butter service.
A tankless water heater is a wall-mounted unit that heats water on demand rather than storing it in a tank. When you turn on a faucet, cold water flows through the unit, hits a heat exchanger, and comes out hot in seconds. No standby energy loss. No 40- or 50-gallon tank taking up space in your garage. The U.S. Department of Energy estimates tankless systems save 20 to 30 percent on water heating costs compared to traditional tank heaters, and they last 20-plus years with proper maintenance versus 8 to 12 years for a standard tank.
