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

Rinnai tankless heaters are known for durability, but they still require maintenance to prevent scale buildup or sensor malfunctions.

If your Rinnai is showing a fault code or you aren't getting the hot water you need, we can diagnose the specific internal component causing the problem and get your unit back to its full efficiency.
