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.

Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.
