Cost for tankless water heater installation — Spokane Valley, WA
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.

Yes, RV tankless water heaters are specifically designed for the unique demands of recreational vehicles. They are typically more compact and built for the mobile environment.

What is a 50-gallon water heater?
A 50-gallon water heater is a common size for many households. It stores and heats 50 gallons of water at a time. This size is often suitable for families with moderate hot water needs.

What does RV water heater repair involve?

What are the signs my water heater is leaking?
Signs your water heater is leaking include visible puddles around the base of the unit. You might also notice rust-colored water or a persistent damp smell.
