Benefits and Cost of Tankless Water Heater

Endless Hot Water

A properly installed tankless water heater will supply your home with endless hot water. At Harmony Plumbing, our expert installers are committed to accurately sizing and installing your new system, ensuring reliable performance for years to come.

Energy Efficient - The Condening Advantage

A condensing tankless water heater uses the exhaust gas to preheat the incoming cold water which creates the most energy efficient way of heating water. The energy efficiency of a tankless water heater is measured in what's called a Uniform Energy Factor (UEF). Our high efficiency Tankless units like the Navien NPE-A2 unit pictured above has a UEF of 0.95. Compare that to a conventional tank based water heater which averages a UEF of .67. That's an almost 30% reduction in energy usage.

Tankless Water Heater Installation & Change Out Cost

The typical cost of a tankless water heater installation is between $2,300 to $5,200.  This includes a correctly sized tankless water heater, necessary government permitting and inspection plus the removal of your old water heater. One of the advantages of a tankless water heater is that it only uses gas while your using hot water. Because it needs to heat water quickly, the gas line going to the unit may need to be sized up, which could result in additional cost.
