Tankless water heater and installation cost — Longmont, CO
Last updated: September 24, 2026
What affects the price
The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.
About this service
This investment covers the hardware and the specialized labor needed to mount the unit and connect it to your home’s utilities. Because tankless units are sensitive to water quality and flow, the installation process includes testing and calibration to prevent future issues.
While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.
