Tankless water heater installation cost factors:

  • The flow rate of the tankless water heater. Flow rate measures how many gallons of hot water a tankless unit can provide in one minute. The higher the flow rate, the more expensive the tankless water heater will be.

  • The fuel type of the tankless water heater. Gas tankless water heaters cost more to install than electric ones, but they cost less to operate on a monthly basis.

  • The warranty length. Tankless water heater warranties vary in length. The longer the length of the warranty, the higher the up-front cost. That said, a longer warranty can reduce the cost of expensive repairs down the road.

How it Works

Our tankless water heater installation process

Process Step
Schedule your free estimate.

You can schedule online or by calling us at (720) 605-7270. We’ll respond quickly to confirm a day/time for your in-home consultation with one of our Comfort Advisors.

Process Step
Get high-efficiency system options.

Your Comfort Advisor will show up on time and inspect your home and current water heater setup. Then, they will chat with you about your hot water needs and budget. After taking into account those factors, they will recommend a water heating system and give you upfront, honest pricing on the cost to install it.

Process Step
Let us install your system.

Once you sign off on the project, we’ll work with you to schedule a day/time to install it. On the appointed day, our installation team will show up on time and get to work right away. They’ll place drop cloths and stay out of your family’s way as much as possible during the installation, which typically takes around 3 hours to complete. Once the tankless unit is installed, we’ll teach you how to use your new high-efficiency water heater.

Process Step
Enjoy lifetime savings and better comfort.

You’ll see significant energy savings after just the first month of using your new tankless water heater. Plus, you’ll notice longer-lasting, more reliable hot water. It’s a win-win!

Casey came by to evaluate installing a new hot water heater in our house. I want to say how knowledgeable, professional and personable Casey was. He patiently explained what would be involved in installing a tankless hot water heater, and clearly identified the costs and timeline.
