A tankless water heater makes hot water on demand instead of storing it, and that changes everything about how it works. Here is the straightforward version of what happens when you turn on the tap.
The flow
When a hot tap opens, the flow sensor in the unit detects the water moving and fires up the burner or elements. Water passes through the heat exchanger and arrives hot in seconds.
The exchanger
A compact heat exchanger transfers the burner's heat into the passing water, which is why the unit is small. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Oxnard, hard water can scale the exchanger over time.
The limits
Because it heats water as it flows, a tankless unit has a maximum flow rate. Running too many fixtures at once drops the temperature, which is why sizing matters.
The ignition
Gas units ignite only when water flows, and they modulate the flame to match the draw. That is what makes them efficient when the hot water use is light.
The venting
The combustion needs proper venting, and the unit needs the right gas line and clearance. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Oxnard, a pro checks these before install.
The maintenance
Descale yearly in hard water and clean the inlet screen to keep the flow sensor accurate. Skipping the flush is the most common way a tankless unit fails.
