Frequently Asked Questions
Yes. We provide fast, often same-day emergency water heater repair and replacement throughout the St. Louis area for no-hot-water, leaking tank, and pilot/ignition issues.
If your tank water heater is more than 10–12 years old, leaking from the tank itself, or needs repeated repairs, replacement is usually the better long-term value. We'll give you an honest recommendation based on the unit's age, condition, and repair cost.
It depends on the size of your household and your hot water demand. We typically install 40, 50, or 75-gallon tanks for residential use and will help you choose the right capacity and fuel type (gas or electric) for your home.
Tankless water heaters provide endless on-demand hot water, take up far less space, are more energy efficient, and typically last longer than traditional tank units - often 20+ years with proper maintenance.
Yes. We handle full conversions from tank to tankless, including any gas line, venting, and electrical upgrades required to install the new unit safely and to code.
Yes. We install, repair, and replace both gas and electric tank water heaters, as well as gas and electric tankless models from all major brands.
We recommend flushing traditional tank water heaters once a year to remove sediment, and descaling tankless units annually (especially in areas with hard water) to keep them running efficiently and extend their lifespan.
Most traditional tank water heater replacements are completed in a few hours. Tankless installations and conversions typically take longer due to venting, gas, and electrical work, but most are completed within a single day.
