Tankless Water Heater Installation & Repair in Upland, CA

Endless hot water, a smaller energy bill, and a unit the size of a suitcase hanging on the wall — that's the tankless upgrade. Option One Plumbing installs, services, and repairs tankless water heaters throughout Upland, from first-time conversions to warranty-preserving annual maintenance.

Upland's water is among the hardest in the Inland Empire, and years of scale buildup quietly shortens the life of water heaters and narrows older pipes. For tankless units, that makes professional installation with proper scale protection — and regular descaling — the difference between a 20-year system and a 7-year disappointment.

Up to 30%+ energy savings versus a standing tank kept hot 24/7

Installation Done Right — Sizing, Gas, Venting, Code

Tankless done wrong is the most common repair call we get. Proper installation means sizing the unit to your household's real flow demand, verifying the gas line can deliver the required BTUs (many conversions need a gas line upsize), correct venting, condensate handling, and isolation valves for future flushing — all permitted and to California code.

Already own a tankless unit? We repair all major brands and offer annual descaling service that keeps efficiency up and manufacturer warranties intact.

How much can I save with a tankless water heater?

Most households see 25–35% lower water-heating costs because a tankless unit only fires when you open a tap, instead of reheating a 50-gallon tank around the clock. Actual savings depend on usage and gas rates.
