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
- 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.
Tankless Water Heater Repairs
- 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.
Tankless Water Heater Maintenance
- 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.
Gas vs. Electric Tankless Water Heaters
Gas Tankless Water Heaters
- Higher flow rates, ideal for larger households.
- Lower operating costs in areas with affordable natural gas.
- Require venting and proper gas line connections.
Electric Tankless Water Heaters
- Easier to install in homes without gas service.
- Lower upfront cost and simpler maintenance.
- May be better suited for smaller households or point-of-use applications.
Our team can walk you through both options and help determine the best fit for your home’s needs.
Is a Tankless Water Heater Right for You?
While tankless systems offer many benefits, they’re not the perfect fit for everyone. They require a higher upfront investment and may involve upgrades to your home’s gas line or electrical system. However, for many homeowners, the long-term savings, convenience, and endless hot water more than justify the investment.
If you:
- Have a busy household with multiple showers or appliances running simultaneously.
- Want to save money on utility bills over time, or
