When to choose a tankless system
Tankless water heaters provide hot water on demand and, when correctly sized and installed, can reduce the space used by an appliance. They are a strong fit for properties that need continuous hot water for showers, kitchens, or small commercial operations where a tank-style water heater struggles to keep up.
Common reasons customers call us
- Intermittent hot water or inconsistent water temperature
- Unit fails to ignite or cycles on and off
- Visible leaks or corrosion at pipe connections
- Reduced flow rates when multiple outlets run simultaneously
- Routine service to preserve performance and avoid unexpected failures
What our service includes
Each service visit follows a clear checklist so problems are identified and addressed efficiently. Typical work includes:
- Full diagnostic of the unit and fuel/electrical supply
- Descaling or flushing the heat exchanger when mineral build-up is present
- Combustion and venting inspection for gas-fired models
- Verification and calibration of temperature controls and flow sensors
- Replacement of defective components and clear, itemized estimates for parts and labor
Installation and replacement
Proper installation is critical for safety and performance. Our licensed technicians perform a pre-installation assessment to confirm fuel type, venting requirements, water quality and the correct unit capacity based on peak usage in the home. We also handle necessary permits and coordinate inspections when required by local code.
Sizing & planning
We size systems using peak demand calculations. This ensures the selected unit maintains required flow rates without oversizing the equipment, which can increase upfront cost unnecessarily.
Maintenance & longevity
Regular maintenance extends equipment life and helps avoid emergency repairs. For areas with hard water, annual descaling may be necessary. Our preventive service includes an inspection, cleaning where needed, and a report with recommended next steps and an honest estimate for any repairs.
Energy and safety considerations
Tankless systems commonly use gas or electricity as their energy source. Gas-fired tankless units require safe combustion and venting; improper installation increases the risk of carbon monoxide exposure. Electric models require properly sized electrical service to handle peak draw. We always verify compliance with safety standards and local code.
Service area and response
We prioritize clear scheduling, upfront pricing and documented work. Our service technicians cover Northbrook and nearby communities. Emergency repair options are available for urgent situations that cannot wait for standard appointment windows.
Job documentation
After each service visit you will receive a written summary that includes the work performed, parts used, any safety notes, and recommended follow-up. This provides clarity for you and any future service professionals.
Frequently asked questions
How often does a tankless unit need service?
Most manufacturers recommend at least one inspection each year. Properties with hard water often benefit from more frequent descaling to prevent mineral buildup that reduces heat transfer.
Will a tankless unit save money?
Savings depend on usage patterns and energy costs. Tankless units can reduce wasted standby energy compared with traditional tanks, but their higher upfront cost means payback depends on how much hot water the property uses.
Can I install a tankless unit myself?
Installation requires knowledge of local codes, fuel and venting requirements, and proper electrical sizing. For safety and to preserve warranty coverage, professional installation is recommended.
