Why do so many people switch to tankless? Mostly three things: a supply that does not run dry, lower standby energy use, and space. A tankless heater stays idle until you open a tap, then fires a high-output burner or electric element to heat water as it flows. With no stored water to keep warm, it wastes less energy between uses, and with regular descaling it can last twenty years or more. It is not magic, though. Performance depends entirely on sizing and installation, which is where most of our work in Paterson, NJ goes.
The most important step happens before anything is installed. We total your peak demand in gallons per minute, such as a shower, a kitchen sink, and the dishwasher at once, and compare it against the temperature rise your incoming water needs in winter. That tells us the real capacity you need. Next we check the supply side. Gas tankless units fire at very high input, so a half-inch line that fed an old tank is often too small. Condensing models vent through PVC or polypropylene and need a condensate drain, while non-condensing units need stainless steel venting. Electric units bring their own demands, often needing multiple large breakers and sometimes a service upgrade.
Every tankless install from Paterson Water Heater includes isolation service valves so future descaling takes minutes instead of hours, a clean gas connection with a sediment trap, correctly pitched and terminated venting, and a pressure relief valve piped to a safe location. If your water is hard, we talk through scale protection, since mineral buildup is the main enemy of a tankless heat exchanger. We can add recirculation for faster hot water at distant bathrooms, set the temperature, handle permits where required, and walk you through maintenance before we leave.

Symptoms That Mean It's Time to Call
Catching a symptom early is often the difference between a quick part swap and a tank that gives out on the garage floor. These are the red flags our technicians see most often before a breakdown:
- A tank water heater that is ten years old or more and due for replacement
- A utility area where a bulky tank takes up room you would rather use
- An addition or guest suite that is a long run from the main heater
- Standby losses on a tank that sits idle for long stretches
- Construction or remodeling that opens walls and simplifies the install
- Showers turning lukewarm before everyone gets a turn
- A growing household or new bathroom adding hot water demand
- Interest in a longer-lasting heater with replaceable parts
Early Action Saves Money
Most water heater failures start small: a popping sound from sediment, a damp spot under the drain valve, or a shower that goes lukewarm a few minutes sooner each week. Call Paterson Water Heater at (973) 221-6774 at the first sign of trouble.

Why Professional Tankless Water Heater Installation Matters
Why not install a tankless unit yourself? Because the risks and the details stack up quickly. Gas piping must be sized for a burner that may draw nearly 199,000 BTU, and leaks or undersized lines are both dangerous and costly. Venting has to match the unit exactly, with the right material, slope, and termination clearances, or combustion gases can end up where they do not belong. Electric models may need a panel upgrade, and warranty terms often depend on a qualified installation. Permits and inspections are common requirements as well.
Our technicians handle the full picture. We size the unit by flow rate and winter temperature rise instead of guessing, confirm gas pressure with the burner at maximum, and install venting and condensate lines exactly to specification. Every install gets isolation valves for easy descaling and a properly piped relief valve. We also give honest advice when tankless is not the best fit. For some households, a high-efficiency tank or a heat pump water heater makes more sense, and we will say so before you spend money on a system that does not match how you live.
Our Tankless Water Heater Installation Process
We follow the same careful process on every water heater, whether it's a quick thermostat swap or a full tankless conversion. Here's the short version:
Size It Right
We count the showers, sinks, and appliances that run together, then size for the coldest incoming water of the year rather than a mild day.
Gas, Venting & Power Check
Whole-home tankless units need big gas lines or big electrical circuits. We verify yours, choose the correct vent type, and plan the condensate drain.
Careful Install
Every connection follows the manual and local code: gas, venting, relief valve discharge, condensate, and isolation valves for future maintenance, with permits handled where required.
Test, Set, Explain
We fire the unit at full demand, check gas pressure under load, confirm the vent and condensate work, set the temperature, and show you how everything operates.
How to Prevent Water Heater Problems
A few preventive steps can help you avoid a cold shower or a wet floor down the road. Here are our recommendations:
- Flush the unit with a descaling solution annually to keep scale off the heat exchanger
- Hard water shortens tankless life, so ask about scale protection
- Clean the inlet water filter screen a few times a year
- Keep the air intake and vent termination clear of snow, leaves, and debris
- Set the temperature around 120F for safety and efficiency
- If the unit shows a recurring code, note it and have it checked
- Protect outdoor or garage units from freezing, and keep power on during cold snaps so freeze protection works
Should You DIY or Call a Pro?
Some simple checks are fine to do yourself, but most water heater repairs benefit from professional tools, training, and experience. A side-by-side look:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Sizing | Sized by the box, not your demand | Sized by GPM and winter temperature rise |
| Gas Supply | Undersized line starves the burner | Line and meter verified for full BTU demand |
| Venting | Old flue reused or wrong vent material | Condensing or stainless venting done properly |
| Electrical | Panel capacity not checked for electric units | Dedicated breakers sized correctly |
| Future Service | No isolation valves, so descaling is a hassle | Scale protection discussed up front |
| Result | Lukewarm water and error codes | Steady hot water at real demand |
