Tankless water heater cost — Boulder, CO
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
The cost of the unit itself varies based on the flow rate, which determines how much hot water it can produce at once, and the energy efficiency rating. If you need a unit that supports multiple bathrooms simultaneously, the price will increase. While the unit is one part of the expense, it is best to consider the total project cost.
