Step one
Begin with the heater you have now
The installation discussion starts with the existing heater and where it sits. Its fuel type, location and connections tell the plumber what the new equipment has to work with, and what might need to change if you choose a different kind of system.
Share what prompted the replacement, whether that is a run of repairs, a supply that falls short, visible wear on the tank or a planned upgrade. Each reason points the equipment conversation in a different direction, so it helps to be specific.
