Tankless Water Heater Install Near Enders Elementary
Not long ago, we had a job around Enders Elementary, near Santa Rita Avenue. The family had just finished a garage-to-room conversion and needed a second water heater. Instead of adding another bulky tank, they wanted a tankless unit on the side wall. Tight gas clearance, limited vent room—but we made it work. Used a compact condensing model with a side vent kit. Took under a day. When we turned on the tap and hot water came on instantly, the dad said, “Shoulda done this years ago.”

How Tankless Water Heater Installation Works
We start by checking your gas line sizing and water pressure—tankless units pull more fuel per minute, so the line’s gotta be up to it. Then we map out where the unit can hang—usually outside wall or garage, depending on venting. We shut off the water, cap the old lines, and install the tankless mount.
Next comes the gas connection, upgraded shut-off, and flue or concentric vent. Then we wire the electric ignition and hook up the hot and cold lines with isolation valves. We run a system flush, test the burners with a combustion analyzer, and finally verify temps at all fixtures. If the tankless is remote-controlled, we mount the panel too.
Average cost in Orange County for full install is about $2,700 to $3,900 in 2025, depending on unit size, gas upgrades, and vent runs.
