Tankless water heater — 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
Tankless water heaters provide hot water on demand by heating it as it passes through the unit, rather than storing it in a tank. This is a great choice if you want to save space and potentially lower your energy use by not heating water you aren't using. These systems can be gas or electric and require professional installation to ensure the gas lines or electrical circuits are sufficient. We can help determine if a tankless model fits your home's needs.
