Water Heater Installation in Sussex, explained.
What influences installation costs in Sussex?
The biggest factor is the unit type: standard tank installations are more affordable than tankless, which require additional venting and gas line work. Adding a new gas line costs $275–$950. Permit fees and the need for an expansion tank on closed systems also add to the total. Older homes may require code upgrades, such as seismic strapping (not required in Wisconsin) or bringing gas lines up to current standards.
