The plumber who came out to our home, William Gough, was personable, professional, and knowledgeable. He talked us through the repair every step of the way. We will definitely call Tennessee Standard Plumbing for any further needs.

Yes, tankless water heaters can replace most tank units. However, some situations may require electrical upgrades or gas line modifications to maximize performance.
Tankless units are compact, needing only 2-3 square feet of wall space, compared to traditional tanks that require 6-8 square feet of floor space.
Annual professional maintenance, primarily descaling to remove mineral buildup, is necessary to keep your tankless system running efficiently.
Installation typically takes 4-8 hours, depending on the complexity of your system and any required infrastructure modifications.
