Navien Tankless Water Heater Installed for a New ADU Build

ADU builds have a lot of moving parts. One thing that can't be an afterthought is hot water. A bulky tank water heater eats up square footage that most ADUs simply don't have to spare - so when a tankless unit makes sense, it really makes sense.

We went with a Navien tankless water heater on this one. Wall-mounted on the exterior, tucked neatly against the stucco, it keeps the interior living space completely clear. Navien is one of the brands we consistently trust. The units are reliable, energy efficient, and built to handle the demands of a full living space without breaking a sweat.

With a tankless system, hot water is heated on demand. No storage tank sitting there all day losing heat. No running out mid-shower. It's a smarter setup for a space that's meant to function just like a primary home.

The connections here are clean - gas line, water lines, and electrical all properly run and secured. That stuff matters. A sloppy install can cause problems down the road, and with an ADU, you want everything buttoned up right the first time so the occupant isn't dealing with issues after move-in.

Whether you're wrapping up an ADU build or just looking to upgrade an aging water heater, tankless installation is one of those jobs where the quality of the work really shows over time.
