Heise's Plumbing recently completed a continuous-flow tankless water heater installation for a homeowner in Downtown Palo Alto, CA. The customer experienced intermittent hot water volume and high gas bills from a aging atmospheric tank unit. Our licensed technicians diagnosed the system, safely decommissioned the old tank, and installed a Navien high-efficiency condensing tankless water heater equipped with new stainless steel venting, gas shut-off valve, and dedicated thermal expansion protection. The unit was thoroughly pressure tested, gas connections checked with electronic leak detectors, and verified for 100% safe, reliable operation.
The Problem
Frequent loss of hot water and leaking temperature-pressure relief valve on an outdated 50-gallon atmospheric tank.
Our Solution
Decommissioned failed tank and installed a premium condensing Navien tankless water heater with dedicated gas line and venting upgrades.
