Inspect the proposed location
Start with photos of the current equipment and available wall space. The technician can assess the proposed equipment location, ventilation, service access, and how the existing lines would connect.
Confirm utility requirements
Ask what the new equipment needs for fuel, electrical power, venting, or condensate drainage. Include those requirements in the written scope so you can compare it with the cost of a similar tank replacement.
Plan for the way you use hot water
Share the fixtures likely to run together and any complaints about slow delivery. Capacity and the travel time to a fixture are separate questions. Ask about both when comparing models.
