Tankless Water Heater Installation in San Jose

Yes. San Jose requires a permit for every tankless water heater installation, and that covers the gas line and venting work too. Once the unit is in, a city inspector checks the gas connection, the venting, and code clearances. IRBIS files the permit and meets the inspector, so you don’t have to.

A straight swap usually takes one day. Add a new gas line, a longer vent run, or a panel upgrade, and plan on two.

In many older homes, yes. Whole-house units want 3/4-inch or 1-inch pipe. Plenty of houses here have 1/2-inch. We measure yours before quoting.

Yes. San Jose won't sign off on a tankless unit without a permit and a passed inspection. IRBIS files the paperwork and meets the inspector.

Incentives change often. The federal tax credit for tankless heaters ended for installs after 2025, and local programs mostly favor heat pump models. We check current eligibility at your estimate.

Usually, yes. Gas tankless models can often vent through an exterior wall. Check with your HOA first. We check the gas line and vent path on-site.
