What Is a Tankless Water Heater?
Tankless water heaters heat water on demand instead of storing it in a tank. When you turn on the hot tap, a heat exchanger instantly warms water to your set temperature. No standby heat loss, no running out during a long shower.
Installation requires proper gas line sizing, venting, and sometimes electrical upgrades. We've converted hundreds of LA homes from tank to tankless and know exactly what each property needs.
Tankless units last longer (15–20 years), take up less space, and can reduce energy costs by 20–30%. Read our tank vs. tankless comparison or call for a free consultation.
