Reliable Tankless Water Heater Replacement Services in Palo Alto, CA

Commercial Tankless Replacement in Palo Alto

Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they share the load.

We also set up a descaling schedule suited to your water usage.

Emergency Tankless Replacement in Palo Alto, CA

A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can usually get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak as soon as we arrive. Call (669) 319-2034 anytime your tankless quits.

Exterior Mount Tankless Units in Palo Alto, CA

Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. Freezing is uncommon along the coast and on valley floors in Northern California, but frosty nights do happen and can crack unprotected outdoor pipes. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.

Recirculation Tankless Upgrades in Palo Alto, CA

If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds.
