Why Our Customers Love Navien

Tankless water heaters are no longer a new technology, and Navien has made sure its latest generation has great features like the following.

Easier and cheaper installation using your existing gas line. For most brands, you need to pay to switch your gas pipes to a bigger gauge. Naviens use the same ½” gas lines that your existing water tank uses.

Maximum energy efficiency available on the market today. Thanks to condensing technology, heat that would ordinarily be wasted is reclaimed and used to heat your water.

One unit can handle both your in-floor heating and your hot water supply needs.

Easy venting solution. Naviens are so efficient that ordinary 2” PVC pipe can be used for venting. No need to spend more on copper!

Frees floor space – perfect for small homes. A Navien tankless mounts right on the wall of your basement. A tank takes up 9 – 16 square feet of floor space.

Can handle small or large hot water needs. If needed, two or more units can be “daisy chained” together.

Say goodbye to flooding when tanks break down. Traditional tanks can flood basements when the bottom corrodes out. Naviens have an emergency shut off if a problem occurs.

Superior quality parts. The heat exchangers are made of stainless steel, not copper. They resist corrosion and hard water scale buildup.

Get money back when government rebates are available. Ask Dr HVAC which rebates are on now.

Great warranty:

  • 15 years on the heat exchanger
  • 5 years on other parts and components

Ultra low NOx emissions at less than 20 PPM.

All the hot water you’ll ever need!

We Install All Navien Models

Here is a little more about Navien tankless water heaters. Dr HVAC will help you figure out which model meets your needs best.

Navien NPE-A Series: 180A, 210A, 240A

The Advanced series has an additional recirculation pump and internal buffer tank that Navien calls “Comfort Flow” technology. It maintains a steady supply of hot water, and eliminates the “cold water sandwich” caused by closing of hot water tap (which shuts off burners).

  • EnergyStar qualified.
  • Efficiency: 95% AFUE to 97% AFUE.
  • Uses efficient ultra-condensing technology.
  • Gas input requirements range from 15,000 – 199,000 BTU depending on model.
  • Flow rates start at 3.8 GPM (14 LPM) and go up to 11.2 GPM (42 LPM) depending on model and temperature desired.

Navien NPE-S Series: 150S, 180S, 210S, 240S

The Standard series doesn’t have the buffer tank and recirculation pump of the Advanced series (below), but if you don’t need these features you can get an extra few points of fuel efficiency. S-Series models can reach up to 98% efficiency.

  • EnergyStar qualified.
  • 96% – 99% efficiency.
  • Heat capacity from 15,000 – 199,900 BTU per hour, depending on model.
  • Flow rates range from 3.2 GPM (12 L/m) – 11.2 GPM (42 L/m) depending on model and desired temperature.

Residential Combi Boilers: 150 E, 180E, 210E, 240 E

A combi boiler can heat your home’s main water supply and can also be used to create hot water for your in-floor heating. If you’ve got tile floors you don’t want to go without it!

  • EnergyStar qualified.
  • 95% energy efficiency.
  • Heat capacity from 12,000 – 199,900 BTU per hour, depending on model.
  • Flow rates range from 2.6 GPM (9.8 L/m) – 4.5 GPM (17.0 L/m) at 77°F (43°C) depending on model.

Helpful Water Heater Terms and Definitions

In the lists above, we’ve mentioned some terms that may be new to you. Here’s what they mean.

NOx

This is the symbol for nitric oxide and nitrogen dioxide, generally measured in parts per million or PPM. These are natural products of the combustion process (your car also produces them), but they must be vented safely to the exterior of your home. Canada, the USA, and other countries are trying to reduce these, so the less the better.

Flow Rate

This shows how much hot water your system can produce. While this depends on the desired temperature, Navien provides measurements at a few standard temperatures so you can get the idea. Ask your Dr HVAC consultant for specifics.

AFUE

This stands for annual fuel utilization efficiency, and is the percent of fuel that gets converted to heat. As you might guess, the higher the number the better, as you want as little wastage as possible.

Is a Tankless Right for You?

Some people love the endless hot water and energy efficiency of a tankless. For others, a traditional tank makes more sense. Dr HVAC carries both, and we’ll help you make an educated decision on making the right choice for your situation.
