Difference between condensing and non condensing tankless water heater.
Non condensing models are the more basic form of gas powered tankless water heater.
The word condense refers to the process of changing matters from gas or vapor into a liquid state.
Non condensing units have efficiencies around 80 meaning around 20 of the heat is wasted and exhausted.
Condensing tankless water heaters extract the additional heat from the exhaust gases through various means and therefore exhaust cooler gases usually around 100 degree f.
They will cool outside the unit.
As such they have only one heat exchanger.
On the other hand condensing tankless water heaters may reduce the expenses for making it able to run overall.

That s the promise of tankless water heaters also called on demand water heaters which produce hot water only when you turn on the faucet start a cycle on the washing machine switch on the.

The first noticeable feature when it comes to condensing tankless water heater vs non condensing types is that the matter only affects gas tankless water heaters.
There is no issue of condensation in the case of electric tankless water heaters.
Let s dissect the meaning of the word condense first.
These gases are around 300 degress and need special materials for the venting to withstand the temperatures and not corrode.
Much like a condensing tankless water heater the non condensing tankless water heaters will push the exhaust gases out a vent to the outside.
It is already established that condensing type of water heater is more efficient than the non condensing type for about 10 to 15 percent.
So what causes the hype.
In this comparison the condensing heaters are objectively better but since they cost more it s all about personal preference in the end.
Since condensing tankless water heaters are generally more expensive than the non condensing this can be considered a push.
