Expert Installation, Maintenance & Repair for All Major Brands
Expert Tankless Water Heater Installation
A tankless water heater is a sophisticated appliance that requires precise installation by a certified professional. Our process ensures your system is safe, efficient, and perfectly suited to your home.
At Principle Plumbing, we handle every aspect of installation, from proper sizing to gas line upgrades and venting, ensuring your new system operates at peak efficiency.
Our Installation Process Includes:
- Proper Sizing: We perform a detailed assessment of your home's needs, considering the number of bathrooms, appliances, and your family's hot water usage to determine the correct size (gallons per minute or GPM) for your unit.
- Gas Line Upgrades: Tankless heaters require a larger gas line (typically 3/4 inch) than traditional tanks. We are fully licensed to perform any necessary gas pipe upgrades safely and to code.
- Venting Installation: Proper venting is critical for safety and efficiency. We install the correct type of venting (PVC for high-efficiency condensing units, stainless steel for others) to ensure your system operates perfectly.
- Plumbing & Electrical: We handle all connections, including installing isolation valves for easy future maintenance and ensuring any required electrical circuits are correctly installed.
Trust Principle Plumbing for professional tankless water heater installation that's done right the first time.
Tankless Water Heater Maintenance & Repair
Naperville's hard water can cause mineral (scale) buildup inside a tankless heater over time, reducing its efficiency and lifespan. Regular maintenance is crucial to protect your investment.
Our certified technicians have the diagnostic tools and experience to service all major brands, keeping your system running efficiently for years to come.
ANNUAL MAINTENANCE SERVICE INCLUDES:
- System Descaling (Flushing): We circulate a special solution through the unit to dissolve and remove mineral buildup from the heat exchanger, restoring its performance.
- Filter Cleaning: We clean the inlet water filter to ensure proper flow and prevent damage to the unit.
- Full System Inspection: We check the burner, venting, and all connections for safety and proper operation.
REPAIR SERVICES:
If your unit displays an error code, isn't producing enough hot water, or is making unusual noises, our certified technicians can help. We quickly identify the issue and perform the necessary repairs to restore your hot water.
BRANDS WE SERVICE:
We are certified to install and service all major brands including Navien, Rinnai, Rheem, Noritz, and more. Our technicians stay up-to-date with the latest technology and best practices.
With Principle Plumbing, you're choosing experienced professionals who specialize in tankless water heating systems. Protect your investment with expert care.
What is a Tankless Water Heater & How Does It Work?
Unlike a traditional water heater that stores and constantly reheats 40-50 gallons of water in a bulky tank, a tankless water heater is a compact, on-demand system. It works instantly, exactly when you need it.
Endless Hot Water: Never run out of hot water again. Run the dishwasher, do laundry, and have multiple family members shower back-to-back without interruption.
Significant Energy Savings: By only heating water when you need it, you can reduce your water heating costs by up to 40%. This is a substantial saving on your monthly utility bills.
Space Savings: These compact units are mounted on a wall, freeing up valuable floor space in your utility room or basement that was once occupied by a bulky tank.
Longer Lifespan & Durability: Tankless water heaters have a lifespan of 20+ years, nearly double that of a traditional tank heater (10-12 years), which is prone to leaks and corrosion.
Cleaner, Fresher Water: Because water isn't sitting and collecting sediment in a tank, you get a continuous supply of fresh, clean hot water.
