Why are our prices slightly higher?

Here at Cooper, we offer the best tankless equipment and the highest-quality installations in Denver, Colorado. Because we go the extra mile to give you the best service possible, we tend to charge a little more than our competition. Cooper only installs the most energy-efficient tankless systems, which means our customers get energy savings throughout the lifetime of the water heater. Plus, our plumbers are some of the most experienced in Denver. So you can also expect fewer repairs and a longer timeframe between replacements.

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. If you have a larger family and tend to see very high hot water use at specific times of the day, a tankless system with a high flow rate is very much worth it.

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. Cooper installs both types of systems. In fact, if you need a gas line installed, we can do that for you, too!

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. If you'd like to know more about extended warranties, don't hesitate to ask one of our plumbers.

"Knowledgeable, professional, and personable…"

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. I appreciated his kindness and professionalism and will strongly consider this company for our HVAC needs based on his visit.
