Extra costs to plan for
City permit: $65. The City of Fort Collins lists a $65 building permit fee per water heater. It should be on your quote.
Expansion tank: $150–$400. Homes with a pressure-reducing valve or check valve on the water line often need a thermal expansion tank when the heater is replaced.
Venting and gas line: $300–$2,000+. Moving from an atmospheric tank to a power-vent or tankless unit can require new venting, and tankless units often need a larger gas line.
Code updates: $100–$500. Seismic straps, a drain pan, a proper T&P discharge pipe and sediment trap may be required to pass inspection.
Emergency and after-hours service. Nights, weekends and holidays usually carry a higher service fee.
