In Malibu
Malibu's water is hard. The county district that serves the city reported about 234 parts per million from one of its supplies in 2025, so tankless heaters here scale up and start running lukewarm or throwing codes. A descale with the isolation valves and a clean inlet filter fixes most of it. In September 2026 we descaled two Noritz units on one Malibu property.
Neighborhoods: Point Dume, the streets above Zuma, Broad Beach and Trancas, Malibu Colony, Malibu Road, Serra Retreat, Sweetwater Mesa.

The job
How it goes
A standard tank draws about 40,000 BTU and a whole-house tankless draws 150,000 to 199,000, which the old half-inch line often can't carry. We upsize it from the meter, and sometimes the gas company upgrades the meter. Condensing units vent in PVC with a condensate drain, and non-condensing units need stainless vent.
We size by how many fixtures run at once and the incoming water temperature, around 55 degrees here in winter. Undersizing is the mistake we see most.
Our hard water scales the heat exchanger, so a tankless needs descaling once a year. The isolation valves we fit make that a half-hour job, on our installs or anyone's.

No room in the closet for a bigger tank

Common questions
Tankless in Malibu: things people ask
- Does the hot water ever run out?
- Not within its flow rate. Two showers at once is fine if it's sized right. Four is too much for any unit.
- Will it cut my gas bill?
- Some, since it heats only what you use. People switch for the space, the longer life and never running out.
- Can my existing gas line handle it?
- Usually not without changes. We size the line from the meter and tell you what has to change before you commit.
