Tankless Water Heater Installation

Dallas / Fort Worth Tankless Water Heater Installation Services

Cowtown Water Heaters installs tankless water heaters in Dallas / Fort Worth homes. I founded this business at a time when homeowners were longing for a sincere, family-owned business.

As a Dallas / Fort Worth native, I empathize with the feeling of running out of hot water mid-shower, or a 50-gallon tank appearing as a monstrosity in your garage or utility closet.

That’s the beauty of tankless units, which heat water on demand instead of storing it. Now, DFW homeowners can get hot water when they need it without expending energy between uses.

Most Texas homes can handle a tankless installation. For example, a 70’s ranch-style home may have an old tank wedged into a hallway closet. Our technicians will remove that and mount a Rannai tankless unit on the exterior wall.

Your household can now enjoy continuous, on-demand hot water while reclaiming your entire closet space. That’s a change you will notice immediately, and it’s why we do this.

When Tankless Makes Sense for Your DFW Home

Are you wondering whether or not you should switch from a conventional tank to a tankless unit? If you’re dealing with any of the following, converting to a tankless unit can produce significant benefits:

  • Running out of hot water with back-to-back showers
  • Damaged flooring or drywall from a leaking tank
  • High gas or electric bills from heating 40+ gallons daily
  • Limited space where the current tank sits
  • Homes with multiple bathrooms competing for hot water
  • Planning a bathroom addition and need more capacity

Despite their extensive benefits, converting to a tankless system may require significant upgrades. For older homes with half-inch gas lines or 100-amp electrical service, we’ll tell you upfront what upgrades you’d need.

Many DFW-area properties built in the 60s through 80s feature undersized gas lines that worked fine for a tank heater, but can’t deliver the BTUs a tankless demands.

Sometimes those upgrades make sense for an electric water heater, sometimes they don’t. Our technicians will lay out everything in detail before moving forward with the installation.


How We Install Tankless Hot Water Heaters


We Evaluate Your Setup

Our technicians will come out and evaluate your existing setup. We look at your gas line size, electrical panel capacity, where the unit would mount, and the venting path.

Tankless heaters require combustion air and exhaust routing, especially on interior installs. We also measure the incoming water flow rate because Dallas / Fort Worth water pressure varies, and the unit requires an adequate flow to fire correctly.


We Recommend a Tankless Model

Our local and industry expertise allows us to make an informed recommendation for a specific model. Condensing units often thrive in the DFW climate because they’re more efficient and have lower PVC venting costs than stainless units.


We Suggest Sizing

Our licensed technicians suggest sizing for simultaneous use. Most households have situations where a shower is running while the dishwasher fills. A family of 4+ people will require a larger capacity than someone living alone.


We Prepare for Installation

On installation day, our technicians will shut off your water and gas supply, disconnect the old tank, and haul it away. Then we mount the new unit and run a new gas line if necessary (often we’re upsizing from half-inch to three-quarter). From there, we connect the hot and cold supply lines and install the venting.

Condensing models produce acidic condensate, so we route a drain line to an appropriate termination point. Then we test-fire the unit, check for leaks, adjust the temperature settings, and show you how the controls work. The whole process usually takes four to six hours, depending on what we run into.

The biggest holdup is usually gas line work. Homes built on slab foundations sometimes have the main gas line running through concrete, which complicates upsizing. Pier-and-beam homes or homes with accessible crawl spaces are conducive to faster installations, but our technicians are trained to handle any situation.
