Rinnai tankless water heater — Kent, WA
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.
About this service
A Rinnai tankless unit heats water only when you turn on the tap, rather than storing it in a tank. This prevents you from running out of hot water during long showers. You should consider this upgrade if your current tank takes up too much space or if you want to lower your utility bills. Exact pricing confirmed free on the call.
