Tankless Water Heaters FAQ – San Jose, CA

How much can a tankless water heater save?

Most San Jose households save 20–30% on water heating costs because a tankless unit only heats water when a tap is open.

Do tankless heaters need maintenance?

Yes – an annual descaling flush keeps the heat exchanger efficient, especially with California's hard water.

Can my existing gas line handle a tankless unit?

Often a larger gas line is needed. We check this during the free estimate and include any upgrade in the quote.

We service Navien, Rinnai, Noritz, Rheem, Bosch and more – error codes, ignition problems and flow issues.
