Water Heater Installation & Repair

Tank and tankless water heater installs, repairs and maintenance from a factory-trained team — done right, done to code.

Tankless water heater system professionally installed on a wall in a Chicago home by 5Star Plumbing & Sewer

Traditional tank water heaters are reliable and budget-friendly, but they take up closet space and run out of hot water mid-shower. Tankless units heat water on demand — providing an endless supply while using less energy and roughly a quarter of the footprint of a 40-50 gallon tank. We install and service both types, sizing the unit correctly for your household's fixture count and simultaneous demand, and handling all gas, electrical, and venting work to Chicago code. Whether you're replacing a failing tank or upgrading to tankless, we walk you through the tradeoffs before you decide.

What's Included

  • Tank & tankless water heater installation
  • Same-day repair for leaks, no hot water & pilot issues
  • Full replacement with code-compliant venting
  • Annual flushing & sediment maintenance
  • Expansion tank & pressure regulation
  • Manufacturer warranty registration

Signs You Need This Service

Rusty or discolored hot water, popping or rumbling sounds from the tank (a sign of sediment buildup), inconsistent water temperature, a unit older than 10-12 years, or visible moisture and rust around the base of the tank all point to a repair or replacement need. A pilot light that won't stay lit or an error code on a tankless unit's display also warrants a same-day service call.
