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
Navien tankless systems are known for their high-efficiency condensing technology, which pulls extra heat from exhaust gases to save on utility bills. If you are looking to upgrade your home's infrastructure to a more compact, modern system, these are a popular choice. They require specific installation expertise to ensure proper airflow and water flow rates. We assess your plumbing setup to see if a Navien unit is the right fit for your home's hot water demand.
