Rinnai tankless water heater — Lee's Summit, MO
Last updated: September 24, 2026
What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
A Rinnai tankless unit heats water only when you turn on the tap, rather than keeping a large tank hot all day. This is a great choice if your household uses a lot of hot water simultaneously or if you want to save space in your utility closet. Because they provide an endless supply of hot water, you won't run out during long showers. We can help you determine if your current gas lines and venting meet the requirements for a Rinnai installation.
