Whether you’re looking to upgrade from a traditional tank system or need reliable service for your existing tankless unit, our licensed plumbers are here to help.

What is a Tankless Water Heater?

Unlike traditional water heaters that store and continually heat a tank of water, tankless systems heat water on demand. When you turn on a faucet or shower, cold water flows through the unit, where gas burners or electric elements instantly heat it. This means hot water is delivered when you need it — and you’ll never run out.

Benefits of Tankless Water Heaters

Tankless water heaters are growing in popularity for good reason. They offer a wide range of advantages over traditional tank-style systems:

Unlimited Hot Water – Enjoy endless hot showers, even with multiple fixtures running at the same time.
Energy Efficiency – Tankless systems heat water only when needed, reducing standby energy loss and lowering utility bills.
Compact Design – These units are wall-mounted and take up far less space than bulky tanks, freeing up floor space in basements or utility rooms.
Longer Lifespan – Tankless water heaters typically last 15–20 years, compared to 8–12 years for standard tanks.
Cleaner Water – Because water isn’t stored in a tank, you don’t have to worry about rust or sediment building up inside.

Tankless Water Heater Installation

Upgrading to a tankless water heater is a smart investment, but it requires careful planning and professional installation. At Rooter66, we:

Evaluate Your Household Needs – We consider the size of your home, number of bathrooms, and hot water usage habits.
Recommend the Right Model – Our team helps you choose between gas or electric tankless units based on energy sources, budget, and performance needs.
Ensure Proper Sizing – An undersized unit won’t keep up with demand, while an oversized one may waste energy. We calculate the right flow rate to ensure peak performance.
Handle Safe, Code-Compliant Installation – From venting and gas line connections to electrical requirements, our plumbers ensure your system is installed correctly the first time.

We proudly install top-quality tankless water heater brands known for durability and efficiency, giving you peace of mind for years to come.

Tankless Water Heater Repairs

Like any appliance, tankless water heaters can develop problems over time. Common issues we repair include:

Mineral Buildup – Hard water can cause scaling that reduces efficiency and flow rate.
Ignition or Flame Failure – Often caused by gas supply issues or dirty burners.
Error Codes – Modern tankless systems display codes when something goes wrong; we can quickly diagnose and fix them.
Inconsistent Water Temperature – Fluctuating temperatures may signal clogged filters, sensor issues, or improper sizing.

Our plumbers have the tools and expertise to troubleshoot tankless systems quickly. We carry replacement parts and provide honest recommendations — repairing when possible and advising replacement only when it’s the smarter option.

Tankless Water Heater Maintenance

Routine maintenance is key to keeping your system running efficiently for the long term. Rooter66 offers annual maintenance services that include:

Flushing the System – Removes mineral deposits and scale buildup.
Cleaning Filters – Ensures proper water flow and heating efficiency.
Inspecting Gas & Electrical Components – Prevents ignition failures or electrical issues.
Checking Venting & Safety Features – Ensures safe operation and compliance with code.

With regular care, your tankless water heater can operate at peak performance for 15 years or more.

Gas vs. Electric Tankless Water Heaters

Tankless systems come in both gas and electric models, and each has unique advantages:

Gas Tankless Water Heaters

Electric Tankless Water Heaters

Our team can walk you through both options and help determine the best fit for your home’s needs.
