What makes this page different: Cypress tankless work is often a closet-tank conversion with an undersized gas branch, not a new-construction hang.
Cypress homes still piped for a tank
Along the Hwy 290 corridor, most Cypress houses we see still have a tank in a hall closet or garage. Tankless installation there starts by asking whether that closet can vent an on-demand unit or whether the heater should move to an exterior wall.
Peak showers, not the brochure gallon rating, set the size. Two baths running while the kitchen fills a pot is the test we use.
Gas and meter checks on the 290 corridor
Builder gas lines in Cypress were sized for a tank heater's short firing cycle. A tankless unit fires the whole time water is moving, and it will fault if the branch is shared and undersized.
We check the meter and the pipe before ordering a Rinnai, Navien, or Rheem. If an upsize is required, it is quoted with the install—not discovered after the old tank is gone.
