Tank water heaters — the dependable workhorse
No hype needed: a quality storage tank is still the right call for plenty of Sonoma County homes — lowest upfront cost, simple to service, and usually replaced the same day you call. Here’s the straight story, including when it isn’t the right call.

Four honest reasons to keep it simple
The trade-offs are right below — no brochure spin either way.
What a tank costs you over time
At PG&E’s local rates a typical family spends $555–$695 a year running a standard gas tank — and 10–15% of that is standby loss, heat leaking from stored water while nobody’s using it. Tanks also last 8–12 years (about half a tankless), take up floor space, and can run out during back-to-back showers. If you’re staying put long-term and use a lot of hot water, the math often favors an upgrade — see our tank vs. tankless and tank vs. heat pump comparisons.
More than swapping a box
A proper Sonoma County tank replacement includes sizing to your household (not just matching the old label), current-code items like seismic strapping, the expansion tank and drain pan where required, gas or electrical connections checked, permit pulled and inspection handled, and the old unit hauled away. And if your existing tank is under ~8 years old with a fixable fault — a thermostat, element, or anode rod — we’ll tell you repair beats replacement.

Tank water heater FAQs
How long does a tank water heater last?+
Typically 8–12 years in our water. An annual flush helps, and replacing the anode rod mid-life can add years.
Repair or replace?+
Under ~8 years old with a fixable fault (thermostat, element, valve, anode) — usually repair. Leaking from the tank body itself, or past 10 years — replacement is the honest answer.
Gas or electric?+
Gas heats faster and costs less to run at PG&E rates; electric is simpler where gas isn’t available — and if you’re going electric anyway, a heat pump water heater is worth a look for 3–4x lower running cost.
What size do I need?+
Roughly: 30–40 gallons for 1–2 people, 40–50 for 3–4, 50–75 for larger households — but recovery rate and your usage pattern matter as much as the number. We size it as part of every estimate.
Do I need a permit and strapping in Sonoma County?+
Yes — water heater replacement requires a permit, and California requires seismic strapping. We handle both as part of the job.
