Water Heater Repair in Larkspur, CA

62% of households in Larkspur heat with gas. That is the strongest free clue to what kind of water heater is in your basement, and it decides which faults are even possible.

Answer first

62% of Larkspur households burn gas for heat, and a water heater almost always sits on whatever line the furnace already uses. That is house heating fuel, so read it as a strong hint rather than as a reading of your own tank. A gas unit fails at the pilot, the thermocouple, the gas control valve, or a flue that will not draft.

HeaterRelay is a referral service, not a contractor. We connect homeowners with independent contractors. Contractors are required to hold whatever credential their state or municipality demands. Every state page sets out who licenses plumbers there and where to check, so you can confirm before work begins. We carry out no work, we sell no equipment, we do not set prices, and we never charge homeowners anything — the contractors in our network pay us when we route them a call.

What Larkspur runs on

Most households here burn gas, which means the tank usually has a flame under it and a vent above it, and both can be the reason for cold water.

Fuel	Share of households
Gas — mains and bottled	62%
Electricity	37%
Fuel oil and kerosene	0%
Everything else	1%

Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 3,431 occupied housing units across Larkspur.

On gas, Larkspur is close enough to the California figure that the difference is inside the survey’s margin of error — so the state pattern is a fair guide here, which is not true everywhere.

Read that as a strong indicator rather than a measurement of water heaters. The Census counts what heats the house; what heats the water usually follows it, and occasionally does not.

Which one do you have

Not sure which you have? A metal flue rising off the top is a gas heater. Two small access panels on the side and no flue is an electric one. Settle that one question and the rest of the conversation is straightforward.

After that it is the symptom that narrows things: nothing at all points one way, running out early another, and a puddle is the one to act on today.
