Installation and Repair
Enjoy endless hot water, lower energy bills, and valuable space savings with high-efficiency tankless water heaters professionally installed in your Greater Cincinnati and Northern Kentucky home.
Tankless water heaters for your home
Tankless water heaters heat water on demand instead of storing it in a tank, so you get continuous hot water as long as you need it—no more cold showers or running out of hot water during back-to-back use. Modern gas tankless systems from leading manufacturers like Navien are compact, wall-mounted units that free up floor space and provide impressive efficiency compared to old-fashioned tank heaters.
Key benefits include:
- Endless hot water for showers, tubs, dishwashers, and laundry—supplied only when you turn on the tap.
- Ultra-high efficiency condensing technology, with models rated up to 0.96 UEF to help trim monthly utility costs.
- Flexible indoor or outdoor installation options and wall-mount design that opens up storage and mechanical room space,
- Long service life and fewer large standby losses compared to traditional storage tanks.
Professional Tankless Water Heater Installation & Replacement
A properly designed tankless system starts with the right sizing, gas supply, venting, and recirculation plan for your home and lifestyle. Our team evaluates your hot water demand, fixture count, and existing fuel type to recommend the best Navien tankless model and configuration for reliable, efficient performance.
Our tankless water heater services include:
- New tankless water heater installation to replace old tank-style units or upgrade existing systems.

Tankless Maintenance & Repair
Like any advanced appliance, tankless water heaters perform best with periodic maintenance and informed service. We provide ongoing care and diagnostics to keep your Navien or other tankless system operating smoothly for years to come.

- Diagnostic testing for ignition, sensors, flow, or error code issues, with genuine parts used where required.
