Lower energy bills, easier on the planet
Navien condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers. The result is a reduction in energy consumption, lower CO2 emissions and low exhaust temperatures allowing the use of less expensive venting materials such as Schedule 40 PVC.
The ultimate in energy efficiency
Navien condensing combi-boilers are Energy Star certified, providing an AFUE of 95.0%. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boiler and storage tank.
