Water Heater Repair in San Rafael, CA

68% of households in San Rafael 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

The fuel a town runs on decides which faults are possible, and San Rafael runs mostly on gas, at 68% of households. That figure is house heating rather than water heating, but the two rarely disagree under one roof. 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 San Rafael runs on

Gas is clearly in front here. The useful consequence is that the fault list is short: pilot, thermocouple, gas valve, and eventually the flue.

Fuel	Share of households
Gas — mains and bottled	68%
Electricity	30%
Fuel oil and kerosene	0%
Everything else	2%

Figures from the US Census Bureau's American Community Survey, 5-year estimates, table B25040, 2023 release, covering 27,889 occupied housing units across San Rafael.

On gas, San Rafael 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.

Strictly, the survey asks what heats the home. Water heating almost always runs on the same supply, but the two can differ in one house without differing in the town.

Which one do you have

Check for a flue. Gas heaters vent; electric heaters have nothing to vent and carry element access panels on the side instead. Knowing which of the two you own is the difference between a diagnosis and a guess.

Then the symptom. Nothing at all and not enough are different faults, and treating them as one is how the wrong part gets replaced.
