Tankless water heaters in Petaluma

Newer east-side Petaluma homes and remodels are more likely to have tankless water heaters — or to be ready for one when the old tank fails. We install, descale, service, repair and replace tankless units. Sonoma County water is hard on heaters; regular descaling keeps a tankless unit running. Error code, hot-then-cold water, or no hot water? Call or text (707) 596-3095. No-cost tankless estimates. More on our tankless water heaters page.

Tank water heater repair & replacement

Older and historic Petaluma homes often still have tank water heaters — and sometimes original galvanized pipe nearby. We repair gas and electric tanks when a part has failed and the tank is sound; we replace when the tank is leaking or the unit is near the end of its life. Heat pump water heaters when space and electrical fit. County overview: water heater repair & replacement.

Signs your Petaluma water heater needs attention

  • No hot water, or it runs out fast
  • Lukewarm or too-hot water
  • Rusty or discolored hot water
  • Popping, rumbling or banging from the tank
  • Water pooling around the base of the tank
  • A rotten-egg smell from the hot water
  • A tankless unit showing an error code or shutting off mid-shower

Whole-house no hot water usually points to the heater (or its gas/power). One fixture usually means a worn cartridge or valve — not a new water heater.

What a replacement includes

  • Removing and hauling away the old water heater
  • Installing the new unit with proper connections and venting
  • Earthquake strapping (required for water heaters in California)
  • Expansion tank installation where needed
  • Testing for leaks and safe operation before we leave

Frequently asked questions

Should I repair or replace my water heater in Petaluma?

If the unit is fairly young and the problem is a part like a thermostat, element, thermocouple or valve, repair usually makes sense. If the tank is leaking or the heater is near the end of its life, replacing it is usually the better buy. We'll tell you which makes sense and give you a price before any work begins. Call or text (707) 596-3095.

Do you charge for water heater estimates in Petaluma?

No. Estimates on water heaters — tank or tankless — are no cost. That no-cost estimate is for water heaters only. Call or text (707) 596-3095.

How much does it cost to replace a water heater in Petaluma?

It depends on type (gas, electric, tankless or heat pump), location (garage, closet, attic), and California code requirements for your home (strapping, expansion tank, venting, permit). Like-for-like tank swaps are simplest; switching to tankless often needs gas line and venting work.
