Is It Time to Upgrade?

Signs You're Ready for a Tankless Water Heater

Your old tank water heater may be costing you more than you realize. If you recognize any of these signs, a tankless upgrade could save you money, space, and frustration—starting with a free estimate from our team.

Running Out of Hot Water

If your household regularly runs out of hot water during showers or back-to-back laundry loads, your tank can't keep up with demand. A properly sized tankless unit delivers continuous hot water on demand—no more cold showers waiting for the tank to reheat.

Aging Tank Water Heater

Tank water heaters typically last 8–12 years. If yours is approaching or past that age, you're living with a ticking clock. Replacing it proactively with a tankless unit avoids an emergency failure and gives you 15–20 years of reliable, efficient service.

High Energy Bills

Tank heaters keep water hot 24/7, even when you're asleep or at work. That standby heat loss adds up. Tankless units only heat water when you need it, cutting water heating costs by 24–34% for most households—savings that compound every month.

Rusty or Discolored Water

Rust-colored water from your hot tap is a sign your tank is corroding from the inside. Once corrosion starts, the tank is near the end of its life. Switching to a tankless system eliminates the storage tank entirely, removing the source of rust and sediment.

Need More Space

A 40–80 gallon tank takes up significant floor space in your utility room, basement, or closet. Tankless units mount on the wall and are roughly the size of a carry-on suitcase, freeing up valuable storage space in your home.

Home Addition or Renovation

Adding a bathroom, finishing a basement, or building an addition increases your hot-water demand. A tankless system can be sized to handle your expanded needs without the footprint of a larger tank—and it's the right time to upgrade while walls are open and permits are already in play.

Our Process

How We Install Your Tankless Water Heater

Our installation process is built on thorough assessment, precise workmanship, and complete testing. Here's how we get your on-demand hot water up and running.

Initial Home Visit & System Assessment

We inspect your current water heater and fuel source, determine hot-water demand by counting fixtures and usage patterns, test water pressure and hardness, review local codes and space constraints, and recommend the right equipment size and type. You receive a detailed written estimate with manufacturer specs, warranty details, permits needed, and a clear installation timeline.

Equipment Ordering & Permit Preparation

We order your chosen tankless unit from Bradford White, Rinnai, or another trusted brand, file all necessary permits with your township or municipal authority, coordinate inspections with the local authority, and arrange delivery to minimize disruption. We brief you on what to expect before work begins and answer any questions you have.

Old System Removal & Prep Work

We shut off power and fuel, drain the old tank safely, disconnect all gas, water, and electrical lines, and remove the old unit responsibly. We then clean and inspect the installation area, prepare mounting surfaces and vent pathways, and ensure adequate ventilation and clearances per New Jersey code and manufacturer safety standards.

New Tankless Unit Installation & Connections

We securely mount the new tankless heater, install hot and cold water supply lines with shutoff valves, connect the gas line or electrical supply with proper pressure regulators and safety valves, install and test the vent system, mount the temperature and pressure relief valve, and seal all wall and floor penetrations. Every connection is pressure-tested under full operating pressure.

System Testing, Registration & Handoff

We flush the new system, test hot-water delivery at every fixture, validate temperature stability and flow rate, confirm all safety features work correctly, and verify energy efficiency settings are optimized. We register the unit with the manufacturer, provide you with the owner manual and a detailed service record, and walk you through operation, maintenance, and our 24/7 support number.

FAQs

Tankless Installation Questions

Most residential tankless installations take 4–8 hours in a single day. The timeline depends on your fuel source (gas is usually faster than electric), whether you need venting work, and any code permits required by your township. We'll confirm the schedule when you book.

Yes. New Jersey requires permits for water heater installations to ensure the unit meets code, venting is safe, and gas/electrical connections are inspected. We handle all permit paperwork and coordinate inspections as part of your installation.

Size depends on your peak hot-water demand—the number of showers, sinks, and appliances that run simultaneously. A family of four typically needs 120,000–150,000 BTU for gas or 15–18 kW for electric. We measure your flow rate and demand during our home visit to recommend the exact size.

It's not recommended. Tankless installations require proper gas line sizing, electrical work, venting, and safety valve installation—all of which must meet New Jersey code. Mistakes can lead to leaks, gas safety issues, or voided warranties. Our certified technicians ensure it's done right the first time.

Gas tankless heaters (natural gas or propane) heat water faster and cost less to operate for large households. Electric tankless units are simpler to install, require no venting, and work well for apartments or small homes but may need electrical upgrades. We'll compare both options at your estimate meeting.

Gas tankless units typically don't need storage, but they may need a small expansion tank to protect against pressure buildup. Electric models sometimes require a mixing valve and expansion tank. We'll assess your plumbing during the visit and include any tanks needed in the estimate.

Homeowners typically save 24–34% on water heating costs because tankless units only heat water on demand—no standby losses. Savings vary by household size, usage, and local energy rates. We provide energy-efficiency details for your specific unit at installation.

Tankless units should be flushed annually (or every six months in hard-water areas) to prevent mineral buildup. We recommend keeping a service contact on file and scheduling annual preventive checks. Proper maintenance extends the unit's lifespan to 15–20 years.

Yes. Bradford White is a U.S.-built brand known for durability and customer support. As a Bradford White authorized dealer, we stock their units and have access to priority technical support. Their tankless models come with solid warranties backed by our team.

Every installation comes with documentation and a manufacturer warranty (typically 5–10 years on the unit). We provide after-installation support and can troubleshoot issues over the phone or schedule a service visit. Our service team is available 24/7 for emergencies.

Yes. We partner with NEIF, Elizabethtown Gas, New Jersey Natural Gas, and Synchrony to offer flexible financing options. Many customers qualify for rebates or incentive programs through their gas company. Ask about current offers when you call.
