Electrical panels in much of Putnam County's housing stock were sized for loads that looked very different from what modern water heaters draw. Half the homes in Putnam County, Missouri were built in 1976 or earlier (2020-2024 ACS 5-year). A contractor pricing a replacement here checks the service panel before the equipment, because an undersized panel turns a straightforward swap into a panel upgrade first. The water heater itself is the smaller variable.
What a New Water Heater Installation Covers

The tank or tankless unit is the heart of the system. A storage tank sits in a utility room, basement, or garage and holds a ready supply of heated water. A tankless unit mounts to a wall in the same general area and heats water on demand as it passes through.
The unit connects to cold water supply lines coming into the house and to hot water lines running out to every fixture. A pressure relief valve mounts directly on the tank as a safety device, and the flue or venting pipe exits through the wall or roof to carry combustion gases outside.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your home.
