Why Norwalk Homeowners Are Switching to Tankless

Traditional tank water heaters store 40 to 80 gallons of water and keep it heated around the clock, whether you need it or not. That standby heat loss accounts for a significant portion of a typical home’s energy bill. Tankless water heaters, also called on-demand heaters, only fire up when you open a hot-water tap—meaning you pay to heat water only when you actually use it. Most homeowners see energy savings of 20 to 35 percent on their water-heating costs after switching.

The other major advantage is endless hot water. A properly sized tankless unit will supply hot water continuously for as long as you need it, making it ideal for large families, homes with multiple bathrooms, or any household where morning showers turn into a race against a depleting tank. Units are available in gas (natural gas or propane) and electric configurations, and high-efficiency condensing models can achieve energy factors above 0.96.

We install and service all major tankless brands including Navien, Rinnai, Noritz, Bradford White, and Rheem. Our technicians are factory-trained, so you get the manufacturer’s full warranty backed by a company that has been in business in this community since 1958. We pull all required permits and handle inspections so the process is completely hands-off for you.

How It Works

Our Tankless Water Heater Installation Process

Step 1: In-Home Assessment

We visit your home to evaluate your hot-water demand, existing gas line size or electrical panel capacity, venting requirements, and available installation space. Most tankless units are wall-mounted and take up a fraction of the footprint of a traditional tank.

Step 2: Sizing and Brand Selection

We calculate the required flow rate (gallons per minute) based on your peak usage—typically the number of simultaneous fixtures running at the same time. We then recommend the right unit for your home and budget, and walk you through gas vs. electric options along with expected payback periods.

Step 3: Permit Pull and Scheduling

We obtain all necessary permits from the City of Norwalk or your local municipality before work begins. This protects your investment and keeps your homeowner’s insurance valid.

Step 4: Professional Installation

Our technicians install the unit, upgrade gas lines or electrical circuits as needed, run new venting (direct-vent or power-vent), and connect to your water supply. We test every connection for leaks and confirm the unit fires properly before leaving.

Step 5: Walkthrough and Maintenance Tips

We show you how to adjust temperature settings, explain the annual descaling flush that extends unit life, and register the manufacturer’s warranty on your behalf.
