Start with the heater you have
Note the fuel type, model and any visible code or flashing-light pattern. Use installation or maintenance records to establish the heater’s age if you have them. Keep covers closed and photograph only what is safely visible; you do not need to diagnose the fault yourself.
Gather the records before deciding
Find the visible brand, model and serial label, plus any installation receipt, warranty document or previous repair finding. Manufacturer parts or tank coverage can differ from labor coverage. Ask what applies to your model and what documentation is required; do not assume the entire repair will be covered.
A repairable part is different from a failing tank
If the problem is cold water or runout, record the timing and affected fixtures. If there is moisture, describe where it appears without diagnosing its source. Ask for the specific finding before comparing options: a failed component on a sound tank and a tank-body leak lead to different questions.
Prepare a precise permit question
If replacement or significant changes are proposed, describe the equipment and intended scope to the City of Berwyn Building Department. Ask which approvals and inspections apply to your address and the proposed work rather than assuming the same requirements apply to every home.
Useful next steps
For moisture around the heater, see the leaking guide. The repair or replace questions help compare scope, and the call checklist gathers the practical details.
