No hot water, lukewarm water, strange noises, or a leaking tank? Before replacing your unit, we'll diagnose it thoroughly. Many water heater problems — failed heating elements, bad thermostats, faulty pressure relief valves — can be repaired at a fraction of replacement cost.

  • Thermostat replacement
  • Heating element replacement
  • Pressure relief valve replacement
  • Anode rod replacement

  • Gas and electric models
  • Same-day installs available
  • Old unit removal & disposal
  • All brands: Rheem, A.O. Smith, Bradford White

Tankless Water Heater Installation

Endless hot water, lower energy bills, and a unit that lasts 20+ years — tankless water heaters are an excellent upgrade for many Bergen County homes. We size, install, and commission Navien, Rinnai, and Noritz systems.

  • Proper sizing for your home's demand
  • Gas line work if needed
  • Venting installation & compliance
  • Navien, Rinnai, Noritz, Bosch
  • Whole-home and point-of-use systems

Boiler Repair & Replacement

Combination boilers and indirect water heaters are common throughout Bergen County's older homes. We repair and replace all boiler makes and models, restoring both heat and hot water when systems fail.

  • Zone valve replacement
  • Circulator pump repair
  • Full boiler replacement & installation

When to Replace
Your Water Heater

Most water heaters last 8–12 years. If you're seeing any of the following, it's time to call PlumEx:

  • Age 10+ years — efficiency drops significantly and failure risk rises
  • Rusty or discolored water — the tank is corroding from the inside
  • Rumbling or banging noises — sediment buildup is damaging the tank
  • Visible rust or moisture around the tank — signs of a failing unit
  • Inconsistent hot water — heating elements or thermostat may be failing
  • Rising energy bills — old water heaters work harder and cost more to run

Water Heater FAQs

What Bergen County homeowners ask us most about water heaters.

How long does water heater installation take?

+

A standard tank replacement takes 2–3 hours for a straightforward swap. Tankless installations or situations requiring gas line or venting work may take 4–6 hours. We always give you a realistic time estimate upfront.

Should I repair or replace my water heater?

+

If your unit is under 8 years old, repair is often cost-effective. If it's 10+ years old and having issues, replacement typically makes more sense financially. We'll give you an honest assessment and let you decide — no pressure.

Is a tankless water heater worth it for a NJ home?

+

For most Bergen County homes, yes — especially if you have a larger family or run out of hot water frequently. Tankless units last 20+ years vs 10–12 for tank units and can reduce water heating costs by 20–30%. The higher upfront cost is usually recovered within 5–8 years.

Do you offer same-day water heater replacement?

+

Yes, in most cases. We stock common sizes and models so we can often complete a replacement the same day you call. Call us at (201) 892-6018 and we'll let you know availability for your situation.
