Condensing tankless water heaters need a condensate drain. This is because when the water is heated, it produces condensation that needs to be drained away. The condensate drain ensures that this doesn’t build up and cause problems with the tankless water heater.

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.
