What affects the price
Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.

Frequently asked in Columbia
How do I properly flush my water heater in Columbia?
To properly flush your water heater in Columbia, start by turning off the power or gas supply and closing the cold water inlet valve. Open a hot water faucet to relieve pressure. Connect a hose to the drain valve at the bottom of the tank and run it to a safe drainage area. Open the drain valve to empty the tank. Once empty, briefly open the cold water valve to stir up sediment and drain again. Repeat until the water runs clear. Then, close the drain valve, turn the cold water back on, and refill the tank before restoring power or gas.

How does an on-demand water heater work in Columbia homes?
An on-demand water heater, also known as a tankless unit, works by heating water only when a hot water tap is opened in your Columbia home.
