Most tank water heaters last 8–12 years in Missouri's hard water. Signs it's time: rusty water, leaks from the tank, repeated repairs, and hot water that runs out fast. We size the new unit to your household, install it to code, and haul the old one away.
Choose from standard tank, high-efficiency, hybrid heat pump and tankless models — and we'll explain the real operating-cost difference.
