hello and welcome back to another
episode of the DIY guy dotnet today
we're going to be showing you how to get
air out of your heating system so first
I'm going to do is shut the boiler off
whether you shut the switch off on the
unit or at the top of your stairs first
thing we want to do is shut the valves
off so we can isolate this loop from the
boiler we're going to shut this ball
valve off here this one's already shut
because there's nothing hook to it for a
basement loop if they ever do it and
this is for the upstairs so we'll shut
this so it's really a two zone the third
zone is not hooked up alright so we're
going to do it zone by its own so what
we need is a garden hose long enough to
hook onto here and go outside we're
going to go ahead and hook that up now
we'll grab a pair of channellocks
I'll go down there just so it doesn't
leak all right so now that we got these
valve shut our hoses Snowdown type of
plier so it won't leak we can get and go
over here where we got the other side of
the zone with the zone valves what we're
going to do is we're going to take from
the auto position and put it to manual
that way it will open the valve and
water will flow through it I'm going to
come back over here we're going to open
this once we open this valve it's going
to allow the fill valve to fill the
boiler with water push it through our
first floor this is the first floor zone
it's going to come out our hose and push
all the air and water outside so we want
to watch the end of the hose so we get a
nice stream of just steady water no air
bubbles in it
there come there get more pretty soon
when it goes all the way through you're
going to want to want it for a little
while to make sure it can go all the way
up through the heat and loop and then
come back out this hose water should
come out cold it's coming from the
baseboard and it should get warm once it
actually goes through the boiler and
that's when we start to get the air
again right here now the hose just
starting to get warm with our boiler
temp water so we know it's going from
the actual boiler all the way through
the line so we'll let it run for a
couple more minutes just to ensure we
get pull the air out so I just want to
mention be careful with the water coming
out of the hose so it'll be hot until
you get the hot water out of the boiler
once you get the air out of this zone
we'll go ahead and shut this valve off
we're going to go ahead and go back on
the other side and shut that zone valve
off and we're going to repeat the
process with the other zone shut that
zone valve over there I'm going to go
from the opener manual back to the auto
so we shut that zone valve off so now
we're going to head and move the hose
so it's not something that fires just to
make sure don't we go ahead and go back
over there we'll open the other zone
valve same thing we're going to slide it
from auto to manual all right now we
have the second-story zone valve open
over there we're going to open this side
of the valve here with our hose on it to
let it flow through the second-story and
push all the water and air out through
the hose now sometimes with a
second-story depending on how high and
how long the run especially with a
third-story it may not really be enough
pressure to push the air through so what
you're going to do is hold up on the
speeder valve that will give it full
pressure and really push that water
through and air and get it all out of
the system just make sure you flip that
back down and then shut the valve so
we're going to let this second story run
for a little bit and get the air out of
line all right we got all the air out of
the second story so like I said we're
going to shut the feeder valve first and
then shut our valve we can go ahead and
shut the zone valve over there all right
now there's own balco's on the second
story over there this valve closed over
here and go ahead and remove the hose
so when you detach your hose you might
want to it handy it's gravity is
going to bring you some water
or you can kink the hose over like I
didn't walk out the bulkhead and set it
outside now that we got our hose
detached we can go ahead and turn on our
valves that way the water will flow
through our whole system making a
perfect loop let's go the valves open
and go ahead and turn on our furnace and
that's it we just showed you how to get
the air out of your heating system or
loops I'm going to get rid of the noise
of the gurgling or banging premiere in
your lives thanks for watching another
