Recommended unit for East Haven
Given Connecticut’s cold northern / humid continental climate and mixed water heating, heat-pump (hybrid) is the sensible default for most East Haven homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

Older homes (median built 1967) may require additional work like updating gas lines or adding an expansion tank if a closed system is present. Permit fees and inspection requirements add to the cost.
