Benefits of Gas and Electric Tankless Water Heater Installation

Installing a tankless water heater, whether it's gas or electric, offers lots of perks. You get non-stop hot water, save on energy costs, and save space in your home. Plus, you can choose between gas and electric based on what works best for you. Here’s a closer look at the benefits each type offers:

Gas Tankless Water Heaters

  • Higher Flow Rates: They can heat more water faster, which is perfect for homes that use a lot of hot water.
  • Operational in Power Outages: If your power often goes out, installing a tankless gas water heater will be a reliable option.
  • Cost-Effective for High Usage: They can save you money over time if you use a lot of hot water because natural gas often costs less than electricity.

Electric Tankless Water Heaters

  • Easier Installation: They're easier to put in because you don't need a vent.
  • Lower Initial Cost: They cost less at the start, so more people can afford them.
  • Versatility and Safety: You can put them in more places in your home, and they're safer because there's no risk of gas leaks.
  • Environmental Impact: Installing a hot water tankless heater is better for the planet, especially when used with clean energy, making your home more eco-friendly.

Installing a gas or electric tankless water heater? Having it installed by experts means it'll work great, be safe, and meet all the rules. Each kind has its perks, so you can pick what's best for your home, what you like, and what services you have available.

A Tankless Water Heater Installation Cost

Choosing a tankless heater cuts down your energy bills and saves a lot of space in your home because you don't need those big tanks like old-style heaters. Even though it costs between $800 and $2,500 to install one, it's worth it. This tankless water heater installation cost is small compared to the money you could lose from safety issues or damage if it’s installed incorrectly.

Is Tankless Water Heater Conversion Possible?

Regardless of your preference for a gas or electric tankless water heater, our skilled installers guarantee a flawless installation. Yet, switching from a tankless gas to an electric model, or vice versa, involves more than a simple swap. Each system demands unique electrical setups, installation techniques, plumbing configurations, and venting standards. Switching types of tankless water heaters is possible, so you can either get a new one or change the type based on what you need. Moving to a gas heater might cost more at first because you'll need to add a gas line and venting setup.

Honest Feedback From Our Clients


Dennis was great, he was very patient and fixed multiple pluming issues very professionally.


Austin Area Plumbing did a great job taking my old toilet out and installing my new one. Dennis and Garrett were very professional and kind. They also did a free check of my hot water heater. The work was quick and top notch quality, and the price fit my budget. Thanks Dennis!


I like to support local businesses that do an outstanding job. I needed outside pipes replaced and Dennis had my water back up and working in no time. He was very professional and easy to work with. The quick service was especially appreciated since I have an infant. Thanks Austin Area Plumbing!
