Tankless installation in Del City is attractive because the 1950s-60s slab-on-grade ranches typically have the water heater in an uninsulated garage with unlimited venting options through the garage wall. The challenge: gas line size. Most original Del City installs have a 1/2" gas line to the water heater that needs upsizing to 3/4" minimum for a modern 199K BTU condensing tankless.
Design decisions we walk through on Del City tankless jobs: fuel choice (natural gas tankless is usually the right answer — electric tankless needs 125A+ of 240V panel capacity that most 1950s Del City panels don't have), sizing (50-gallon-equivalent is typical, Navien NPE-240A2 handles this), venting (concentric PVC sidewall out the garage wall is clean and code-compliant), and softener pre-treatment (OKC water at 10-15 GPG is hard enough to need it).
Default Del City install: Navien NPE-240A2 garage wall-mount, concentric PVC sidewall vent, gas line upsize to 3/4", HALO 5 softener. Use our Water Heater Finder tool to get a personalized recommendation and save $100 off tankless installation.
