no. it takes air from outside, burns gas, cools the exhaust to the water temperature condensing some moisture some then expels the exhaust (at 100% humidity) and some liquid condensate. Importantly it doesn’t release dry air, and it doesn’t release it indoors.
What is the advantage of a condensing tankless water heater?
A condensing tankless water heater can recycle that extra heat. It only vents the vapor when it is no longer useful for the heating process, and is known as a closed system. The vapor from a condensing tankless water heater is much cooler. Therefore it doesn’t require the same expensive and elaborate venting material.
Which is better a condensing or non-condensing tankless water heater?
Not only is venting more cost effective with a condensing tankless water heater, but they’re also more efficient. All condensing tankless water heaters run above 90% efficiency, while non-condensing tankless water heaters usually run in the 80% range.
How much water does a condensing tankless water heater produce?
Although only a maximum of two gallons of liquid per hour is released, it will accumulate if improperly drained.
How does a condensing tankless water heater work?

Quote from Youtube video: The heated water is then balanced by the computer controlled water bypass valve. So that the hot water exiting the unit is the perfect temperature.
Are condensing tankless water heaters worth it?
They Save Energy
Low energy consumption translates to more cost savings in operation and maintenance. All condensing tankless water heaters are now being manufactured to meet efficiency scores of more than 90%. In contrast, non-condensing water heaters operate at just above 80.
Are condensing water heaters worth it?
Instead of sending hot exhaust gases out the flue, which wastes energy, this heater blows them through a coil at the bottom of the tank. Incoming cold water flows around the coil and collects most of the heat. That’s why condensing gas water heaters are so efficient (up to 96 percent thermal efficiency).
Which is better navien vs Rinnai?
Navien Water heaters have an advantage when it comes to being energy efficient. Navien units have UEF ratings of up to 0.96 while Rinnai Units max out at approximately 0.93. The more efficient the unit is, the less energy waste which translates to more energy savings.
Do you need a drain for a tankless water heater?
A: Drain pans are not required for tankless water heaters at all. They are required for tank type water heaters located where a leak will cause damage to the building.
How do you drain the condensate in a tankless water heater?
Quote from the video:
Quote from Youtube video: Then we come down with like a two inch piece we put a t. Then we put a street out then we put about another two inch piece up you don't need to go all the way up all you need to do is vent the pipe.
Do I need a condensate neutralizer?
Condensate neutralizers are crucial for treating acidic condensate from high-efficiency heating appliances. Without a neutralizer, condensate has the potential to corrode a building’s foundation, floors, and drainage system. Properly installing a neutralizer is fundamental, but only part of the solution.
How long does a condensate neutralizer last?
How Long Do Neutralizers Last? Condensate neutralizers can last many years without needing to be serviced apart from replacing the media. We are so confident in our Fireside condensate neutralizers that we offer a 10-year warranty on our units, which is the best in the industry.
What is a neutralizer on a tankless water heater?
The 9007607005 Neutralizer assembly neutralizes the condensate (acidic water) that forms in the secondary heat exchanger of the water heater. It connects to the condensate drain port of the water heater by using connectors included with the neutralizer kit.
Does a tankless water heater need a condensate neutralizer?
Quote from the video:
Quote from Youtube video: So the neutralizer is filled with stones as you can see here which raise the pH level of the condensate. So it's no longer acidic. And it makes it safe for discharge into the sewage or septic. System.
What are condensate neutralizers?
A condensate neutralizer is a reliable, purpose-built solution. It serves as a filtration device for the acidic condensate created during the combustion process in gas-fired, high-efficiency appliances. As the appliance extracts heat from exhaust gases, the vapor in the gases condenses into a liquid condensate.
