Tankless Water Heaters And Cold Shots of Water


The Navien Advantage

Only Navien tankless heaters offer “Comfort Flow” Technology to eliminate cold water shock associated with other tankless systems. Navien’s unique buffer tank in conjunction with the recirculation pump assures faster delivery of continuous heated water and no shots of cold water.

Navien was also first to offer dual stainless steel heat exchangers, rather than copper. This extends the life of the unit by resisting corrosion. Also backed by the industry’s strongest residential warranty, 15 years on the heat exchanger, 5 years on parts, 1 year on labor. The units are also LP/NG convertible.


Unlike systems that waste energy to heat large tanks of water. Navien tankless units utilize 99 cents on every dollar to heat your water. Unlike the conventional tank system, it only fires up when hot water is needed allowing great utility savings and a lower impact on the environment. Navien tankless heaters even reduce CO2 output by 1,216.8 lbs.* per year compared to the traditional tank type heaters. This would equal to saving 62 gallons of gasoline in your car.

The NPE-240A  is the best residential tankless unit, it has a 199,000 BTU rating. Meaning your unit will heat up more efficiently and have better water distribution. For instance while in the shower you will have the same continuous hot water and pressure even if someone decides to use the washer at that point in time. Units with a lower rating of BTU’s will have issues with GPM (gallons per minute) and keeping continuous hot water flow to all fixtures. Therefore making the NPE-240A the only unit we like to install.

Addition Features

The NPE-A series offer a couple different addons which give your unit an upper hand on efficiency and personal comfort.

First being the Navien Hot Button, The Hot Button activates the recirculation pump and gas-fired burner to heat up the water in the supply lines. Compared to the pump running 24/7 or on a timer. This gives you hot water when you need, rather than waiting for it to make its way to your shower, tub, etc. This add-on accessory saves you water and money.

Next, The H2Air kit utilizes the NPE-A pump to circulate the hot water for the use in a hydronic air handler. This removes the need to purchase an additional circulating pump for the heating system. Designed for both retrofit and new construction residential applications. The H2Air Kit consists of an add-on controller that allows for space heating and DHW system integration between NPE-A series tankless water heater models and a hyrdronic air handler. Also compatible with single or dual-stage thermostats.

Last but surely not least, The Navi Link wifi remote control system. This will enable customers to use their smart phones or tablets to control the temperatures remotely, access usage data and receive diagnostic notifications on all Navien products (NPE-A, NPE-S, NCB-E, NHB). Existing installations/stock may require the purchase of a new main PCB (control board) and front control panel.
