good afternoon YouTube so this is the condensate drain off my tankless water
heater and normally it runs down into the standpipe that the clothes washer drains into
I've just been curious as to how much liquid actually comes out when you run the heater
so what I did was I just ran a load of dishes in the dishwasher I have the hot water set to
140 Fahrenheit which is about 60 Celsius and I think I missed maybe the first hot water cycle
anyway that's how much condensate I picked up off of almost a full cycle on the dishwasher
we're not talking about a lot of liquid I think this is a six ounce cup and the other
thing I wanted to do was see what kind of pH this has so let's see I just calibrated this
with some buffer solution I kind of stir it around a bit and I let this kind of come to
room temperature so it's probably 25 L seus which is about where this was calibrated so
55.1 pH but like lemon juice is pH 2 so this is much less acidic than lemon juice
like I said this is I think as a six ounce cup and that says one-quarter so that would be one and a
half ounces so this is the drain where the clothes washer empties into as well as the utility sink
comes in from the side the detergent residues from the clothes washer are in that section of drain
line and that can help to reduce the acidity of the condensate I think there's maybe four cycles
it fills with hot water runs the detergent then does a rinse and then I think it does another
fill and another rinse and this heater runs those four cycles and that's as much liquid
as you get and that spread out over maybe 20 25 minutes whatever the washing cycle takes you're
not talking about very much liquid coming out of one of these of course if you have a bigger
heater and you're filling a big bathtub and then the heaters gonna run for 20 minutes straight well
then you're gonna have more condensate but normal operation just not that much liquid that comes out
and it's a fairly warm humid day here for this area I don't know if that affects things maybe
they'll be a little bit more in a cold winter day then on a hot summer day I don't know I never see
a solid stream of water back there it's just drips it'll be a jug of water and then there's nothing
and then another drop of water and nothing that drains as fast as the condensate can build up it's
not like it's backing up but that's kind of what I wanted to find out was how much water are we
talking about and you know is this battery acid or soda pop you're not dealing with a lot of volume
and water that's coming out of there is really not terribly acidic maybe other fuels are worse
natural gas methane ch4 there's really not much in there I guess you have a little bit of the odorant
that they put in there have some sulfur in it but that's like a really low concentration so you
might get a little bit of sulfur dioxide coming out of the air with sulfuric acid and this heater
is low NOx so that's got very low nitrogen oxide output so yeah maybe other heaters higher NOx
heaters that run at higher temperatures or higher busting pressures might have more NOx but but yeah
if you have any questions about that post up in the comment section below and I'll put some of
the other tankless water heater videos over here on the left side and as always thanks for watching
you
