Tank vs. Tankless Water Heaters — Which is Right for Your St Louis Home?
Tankless water heaters, also known as on-demand water heaters, can be a smart and efficient choice for modern homes. Unlike traditional water heaters that store and continuously heat water, tankless water heaters heat water directly as it flows through the unit. Call (314) 962-0956 or Contact Us to upgrade to a tankless water heater today and experience the difference in efficiency and performance.
Benefits of Tankless Water Heaters
- Energy Efficiency: Tankless water heaters only heat water when needed, significantly reducing energy consumption and lowering utility bills.
- Endless Hot Water Supply: Enjoy an unlimited supply of hot water on demand, perfect for households with high hot water usage.
- Space-Saving Design: The compact, wall-mounted design of tankless water heaters frees up valuable space in your home.
- Extended Lifespan: Tankless water heaters typically last longer than traditional tank water heaters, providing reliable performance for many years.
- Low Maintenance Requirements: With fewer components and no tank to maintain, tankless water heaters require less frequent maintenance and are easier to service.
- Lower Operating Costs: The energy-efficient operation of tankless water heaters can lead to significant savings on your energy bills over time.
- Eco-Friendly Solution: By using less energy, tankless water heaters help reduce your carbon footprint and support a more sustainable lifestyle.
- Consistent Water Temperature: Experience hot water at a consistent, reliable temperature without the fluctuations common in traditional water heaters.
Considerations: Tankless versus Tank Water Heaters
- Limited Hot Water Flow Rate: While tankless water heaters provide an endless supply of hot water, they may struggle to deliver enough hot water simultaneously to multiple outlets (e.g., showers, dishwashers) depending on the model and capacity .
- Maintenance Needs: Tankless water heaters may require more regular maintenance, especially in areas with hard water, to prevent scaling and ensure efficiency. This might include periodic descaling and flushing of the unit.
- Power Outage Dependency: Unlike tank-style heaters that can store hot water, tankless heaters provide hot water only when there’s power. During a power outage, you’ll have no hot water available.
- Longer Wait Time for Hot Water: Since tankless heaters heat water on demand, there might be a slight delay in getting hot water at the faucet compared to a traditional tank heater. However, a circulation pump can solve the delay in either case.
- Higher Initial Cost: Tankless water heaters generally cost more upfront than traditional tank water heaters, both in terms of the unit itself and the installation.


Upgrade to a tankless water heater today and enjoy endless hot water, energy savings, and peace of mind. Call (314) 962-0956 or Contact Us now for expert installation services and experience the benefits of a modern, efficient water heating solution in your home!

It depends. We know that’s an unsatisfying answer, but if your unit is under five years old, a yearly flush can keep it efficient and quiet.

My basement flooded and my water heater was exposed to standing water. Do I need a new water heater?
It is generally recommended to replace a water heater that exposed to standing water.
- Gas Water Heaters: If the burner or control valve was submerged, these components can be severely damaged and pose safety hazards. Replacement of the entire unit is usually recommended.
- Electric Water Heaters: If water reached the heating elements, thermostat, or wiring, these parts can short out and create safety issues. Replacement of the entire unit is often necessary.
- General Consideration: If the water heater is nearing the end of its typical lifespan (8-12 years for most models), replacing it might be more cost-effective than repairing or risking future failures.
