Endless hot water, 18–25 year lifespan, lower running costs. Navien is our specialty — we’ve installed hundreds across Hoboken brownstones, JC condos, and Hudson County row homes.
Instead of keeping 40–75 gallons of water hot 24/7 (like a tank), a tankless unit heats water on demand — only when you turn on a hot tap. Cold water flows through a heat exchanger, gets heated instantly, and reaches the faucet at the temperature you set. When you turn off the tap, the unit shuts down.
Result: no standby heat loss, no 5am alarm when the tank runs out during back-to-back showers, no rust-from-the-inside tank failure at year 10. Tankless costs more upfront, but the math wins long-term — especially for families and multi-bathroom homes.
Tankless makes more sense in Hoboken/JC than almost anywhere else — small mechanical rooms, multi-bathroom homes, and long-term ownership all push the math in tankless’s favor.
Take back-to-back showers, run the dishwasher, fill the bathtub. Tankless keeps producing hot water indefinitely — sized right, you literally can’t run out.
Tanks last 8–12 years. Tankless units last 18–25 years with maintenance — often twice as long. Over 20 years of ownership, you replace one tankless instead of 2–3 tanks.
No standby heat loss (heating water you’re not using). Most homes save 20–30% on water-heating gas/electric vs. tank. Federal tax credits (25C) often apply to qualifying condensing units.
Navien is our specialty — reliable condensing units, strong local parts supply, integration with combi heating systems. Rheem and Rinnai are our other primary installs.

Tankless sizing is in GPM (gallons per minute) — based on how many fixtures you might run simultaneously, not total water usage per day.
Single-bath / smaller home: 5–7 GPM. 2-bath home: 7–9 GPM. 3+ bath or family with simultaneous fixture use: 9–11+ GPM. Condensing models hit higher GPM at smaller physical footprint.
Condensing units (95%+ efficiency, sidewall PVC venting): higher upfront, lower running cost, qualifies for tax credits. Non-condensing (80% efficiency, stainless steel chimney venting): cheaper unit, higher running cost.
Standard tankless: just hot water. Combi tankless (Navien NCB, Rheem combi): does both hot water + hydronic heating in one unit. Great for brownstones with existing boilers due for replacement — one unit instead of two.
Tankless burns more gas while running (briefly) than a tank does. Existing gas line may need upgrading from 1/2" to 3/4". Condensing units need sidewall PVC venting. We assess on the in-home estimate.
Tankless install is a bigger project than tank replacement — especially first-time conversions. Three pieces drive the scope.
In-kind tankless replacement: predictable, fast. First-time conversion from tank: includes new venting (PVC sidewall typically), possible gas-line upsizing, water-line modifications. Adds 4–8 hours of work.
Tankless can require larger gas line than a tank used. If your existing line is 1/2", we may need to run 3/4" to the new unit. Quoted separately so you see the line item.
Condensing tankless needs PVC sidewall venting (usually through exterior wall) plus a condensate drain. Non-condensing needs stainless steel through the existing chimney. We verify on the in-home estimate which path works for your home.
In-kind tankless replacement: typically $4,000–$5,500 installed. First-time conversion from tank: $5,500–$8,500 installed (depends on gas line + venting work). Federal 25C tax credit often applies. Call 201-245-5151 for an in-home estimate.
Tankless units need annual descaling to maintain efficiency. Most repairs are control-board, flow sensor, or ignition-related.
