Rinnai tankless water heater — Daly City, CA
Last updated: September 24, 2026
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.
