Thinking About Going Tankless? Start Here

What is the best tankless water heater for a Brownsburg home?

Navien is our top pick for most homes, and it’s the brand our certified installers work with every day. Many Navien models offer a hot water recirculation option that delivers warm water to the tap faster, with no extra water lines added to the home. During your free estimate, our team will recommend the Navien model that matches your household’s hot water use and available space.

Which is better, an electric or gas tankless water heater?

Gas tankless water heaters are the stronger choice for most Brownsburg homes, especially those with multiple bathrooms running hot water at once. An electric tankless water heater costs less to install and works well in smaller homes, finished basements, and additions. Our plumbers will lay out the pros and cons of each so the choice is easy.

What size tankless water heater does my home need?

Most homes need a unit that can handle two or three fixtures running at the same time. Indiana’s cold winter groundwater also means the unit has to work harder in January than in July. Our technicians measure your home’s peak demand, so your hot water never falls short.

How often does a tankless water heater need maintenance?

Plan on professional tankless water heater maintenance once a year. Central Indiana’s hard water leaves mineral scale inside the unit, and an annual flush keeps it running efficiently and error-free. Our Maintenance Plan keeps yearly service on schedule.

“Ryan was wonderful! He quickly found not only the issue with our new water heater but also detected & fixed a gas leak we were not even aware of. He was prompt, friendly, courteous & professional. We couldn’t have asked for a better plumber & we will definitely request him should another need arise. Thanks so much Ryan!”

“Ryan from Steg was absolutely great. From his punctuality of showing up on time, to his communication of the process, and down to the execution of the work he did, I am very satisfied. Should I ever have any issues in the future I hope Ryan would be the one to come back and handle the job.”
