What does it mean to be Non-Condensing?
A Non-Condensing tankless water heater will push the gases created by the water heater through its vent to the outside. They will then cool down outside the unit. These gases have temperatures around 300 degrees F and must be vented through non-corrosive venting materials that can withstand the heat.


Takagi offers a 15 years warranty on the heat exchanger and 5 years on the parts. Read the Warranty Policy before purchasing.
