Frequently Asked Questions
What areas around O Fallon does HotFlow cover?
Coverage extends through O Fallon and surrounding the greater metro area. If you're near but not sure you're inside the service area, call (877) 823-0233 to confirm.
Should I repair or replace my gas water heater?
It generally depends on the unit's age and what's failed. A control valve or thermocouple issue on a newer tank is usually worth repairing; a rusting tank near the end of its typical service life is often better replaced. A technician can advise after inspecting it.
How long does a typical gas water heater last?
Most tank-style units last around 8 to 12 years depending on water quality and maintenance. Tankless units tend to last longer with proper upkeep. A technician can assess your specific unit's condition.
