Be Bold! Go Tankless!

Last year my family and I built our second home in Josephine Crossing, and for first time in our lives we owned a tankless water heater.  I was really excited. Why?  Because I really like saving money, especially when it requires me to do nothing. 

We have the Navien NPE-180S, the same water heater we install in our new homes in Annafeld.  While not very big, measuring only 28.8″ tall and 17.3″ wide, this sleek machine is a powerful workhorse. 

How Does A Tankless Hot Water Heater Work?

When a hot water tap is opened, water travels through the unit and is heated very quickly to about 120°by a gas burner and sent to the requested destination, providing a continuous supply of hot water. The beauty of this and other tankless water heaters is that it works only when you need it—when you take a shower, start the dishwasher or washing machine, or wash your hands in the sink.  When none of these are being used, your Navien 180s rests. Whether that is for 5 minutes or three weeks, it simply will not use energy to heat water while off-duty. It patiently waits until it is called upon again. The result? Minimal energy waste.

Compare this to a conventional storage hot water heater, or tank heater, which must use energy to ensure a minimal and acceptable heat is maintained at all times. According to information provided at, an office of the U.S. Department of Energy,

“Since water is constantly heated in the tank, energy can be wasted even when a hot water tap isn’t running. This is called standby heat loss…” 

Standby heat loss costs money.  A tankless water heater, on the other hand, does not store hot water for use at a later time, so there is no gas wasted on heating stored water.  This makes a tankless option more efficient which saves you money. 

Cost Comparison

Consider the annual costs of a Navien Tankless water heater to a traditional “tank” water heater.

Annual Operating Cost:  Tankless vs. Storage Water Heater



Clearly, the tankless wins the prize for annual savings.  And according to the The Department of Energy,

“Most tankless water heaters have a life expectancy of more than 20 years.”

Multiply that annual savings over the life of the heater, and you’ll realize a few thousand dollars of energy costs saved.  See why I am so excited about our tankless water heater?!?

And I’m not the only one. Here at McCall Homes, we are committed to building energy-efficient homes. Saving our homebuyers money over the life of their home is a predominant factor in selecting what features we install in our homes. The Navien heater is just one of numerous components we have utilized in order to bring energy savings as well as comfort to the lives of our new neighbors. Stay tuned for more information on this topic, such as our recently formed partnership with Owens Corning (think Pink!) and the amazing new insulation procedures that are currently underway in our freshest neighborhood, Annafeld.
