Tankless water heaters — the long-term play for Hudson County homes.
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.
How tankless water heaters work.
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.
Built for how Hudson County homes actually use hot water.
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.
Endless hot water
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.
18–25 year lifespan
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.
Lower running cost
No standby heat loss (heating water you’re not using). Most homes save 20–30% on water-heating gas/electric vs. tank.
Tankless brands we install & service.
Navien is our specialty — reliable condensing units, strong local parts supply, integration with combi heating systems. Rheem and Rinnai are our other primary installs.

Picking the right tankless setup.
Tankless sizing is in GPM (gallons per minute) — based on how many fixtures you might run simultaneously, not total water usage per day.
GPM capacity
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 vs. non-condensing
Condensing units (95%+ efficiency, sidewall PVC venting): higher upfront, lower running cost. Non-condensing (80% efficiency, stainless steel chimney venting): cheaper unit, higher running cost.
Standard vs. combi units
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.
Gas line & venting
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.
Existing infrastructure
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.
Gas line upsizing
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.
Venting & condensate
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). Call 201-245-5151 for an in-home estimate.
Install, repair, or maintain — we do all three.
Tankless units need annual descaling to maintain efficiency. Most repairs are control-board, flow sensor, or ignition-related.
