The reasons that matter

Why choose a Navien water heater?

Efficiency first

Navien water heaters are designed for high performance while saving energy.

Durability

Stainless steel heat exchangers and tanks for a long service life.

Smart technology

Wi-Fi connectivity and intelligent control options.

Hot water, always

With a tankless model you'll never run out of hot water, and our heat pump water heaters offer customizable operating modes to meet changing demand efficiently.

The Navien advantage

Why Long Island chooses Navien — and chooses us

Endless hot water, tankless efficiency

Navien condensing tankless water heaters heat water only as you use it — no standby tank losses and no running out mid-shower. They're far more efficient than old tank systems, reaching up to 0.97 UEF, ENERGY STAR certified and backed by up to a 15-year heat-exchanger warranty.

Powerful flow for the whole home

While some tankless units only manage 2–3 gallons per minute, Navien builds some of the most powerful tankless water heaters on the market — delivering the flow rates needed to run multiple fixtures at once in a busy Long Island home.

Factory-authorized installation only

Navien recommends using only factory-authorized installers for tankless water heaters — and that's exactly what we are. Authorized installation protects your warranty and ensures the unit performs to spec for years.

Replacing an old tank heater

Many Long Island homes still rely on an aging tank water heater. When it's time to replace, we right-size a Navien tankless (or heat pump) unit for your household, handle the install cleanly and set you up for lower bills and endless hot water.

Questions & answers

Navien service FAQs

How much can a tankless water heater save me?+
Condensing tankless units are significantly more efficient than standard tank heaters because they eliminate standby losses and heat on demand. Actual savings depend on your usage, but many homeowners see a meaningful drop in their gas bill.
Will I really get endless hot water?+
Yes — a properly sized Navien tankless heats water continuously as it flows, so you won't run out. We size the unit to your home's peak demand so it keeps up with multiple fixtures.
What's the 'cold water sandwich' and does Navien fix it?+
It's the brief burst of cold water some tankless units send between hot draws. Navien's ComfortFlow models with a built-in buffer tank and recirculation pump are designed to eliminate it.
Which Navien water heaters do you install?+
We install and service the condensing NPE-A2 and NPE-S2 series, the NHW series with ComfortFlow, the non-condensing NPN units, and Navien heat pump water heaters.
Do you offer emergency water heater service?+
Yes — no hot water is treated as an emergency, and we respond 24/7 across Long Island.

I have nothing but good things to say about this company and their employees! I needed emergency service at 4am and they responded within a half hour! And even at that early morning hour they were pleasant and efficient! I have since signed up for a service contract with them and am confident that the excellent service will continue.
