Hot water that runs out quickly can come from demand exceeding recovery, an undersized system, a control/equipment problem or a change in usage. The timing and whether performance changed suddenly help separate those paths.

What changes the hot-water demand pattern
Look at when hot water is used, not only how many people live in the home. Consecutive showers, simultaneous fixtures, dishwasher/laundry overlap and recovery between draws can turn the same tank size into very different experiences.

What the symptom can point to
Record what happens before, during and after a heating cycle. Whether the system starts, reaches normal heat, shuts down early, runs continuously or fails to reach setpoint helps narrow the branch without assuming one failed part.
How the HouseIt tool makes this more specific
The tool asks only for facts that can change the branch or result. Unknown answers stay unknown, and the result should become more cautious rather than inventing precision.
Safety and limitations
Do not perform gas, combustion or energized electrical servicing based on an online result.
