00:00:02
redoing another boiler room, the main
00:00:06
feature is that we will be
00:00:08
redoing one that has already been converted to the body, that
00:00:11
is, we will be in 4 those who will be
00:00:13
working on the heating system in this
00:00:15
building, I will tell you the backstory of the stones,
00:00:19
the owner of this house asked about
00:00:22
four months ago to let us build a
00:00:24
heating system As far as I
00:00:26
understand correctly, he purchased that building with seals
00:00:28
when the communications were unfinished, and
00:00:31
upon closer examination, this is what I
00:00:34
discovered: a gas double-circuit
00:00:36
boiler, the entire system was made of
00:00:40
polypropylene without diffusion protection, it was
00:00:43
very crooked under the ceiling, and the
00:00:47
collector wiring was to the
00:00:48
radiator network, the pipe in many places was
00:00:51
very bad sagged around
00:00:52
obstacles, these are very large
00:00:55
potential
00:00:57
air pockets,
00:00:59
I came to the conclusion that it was necessary to
00:01:01
dismantle the entire system of the
00:01:04
customer, he refused this, considered it
00:01:08
necessary to preserve it, well, it probably
00:01:12
seems to me that we no longer worked together precisely
00:01:14
because I could not promptly
00:01:16
respond to his request and
00:01:18
solve it the problem was not very
00:01:21
busy at that time and he turned to
00:01:23
another organization after some time, about
00:01:25
4 months, he probably turned to me
00:01:28
again with a request of 300 with a similar
00:01:31
request, only this time the
00:01:33
heating system had already been redone, but for
00:01:36
work and, in principle, it’s not the same
00:01:38
comfortable not as well thought out as we would like
00:01:40
it to be let's go see
00:01:43
what we have today
00:01:47
gas candy sleepy rings vaillant
00:01:51
hydraulic separator
00:01:53
manifold and pump for pine trees and groups that
00:01:57
is a direct circuit for you to the temperature
00:01:59
radiator sit down and 2 low temperature
00:02:02
circuits space for the tank
00:02:06
warm collectors the floors at
00:02:09
first glance seem to look decent, the
00:02:12
quick installation group, the hydraulic
00:02:15
separator, the boiler is made of everything with a copper
00:02:17
pipe, one gets the impression that
00:02:19
the work was done by professionals, but let’s
00:02:22
look at a few of the main
00:02:24
mistakes that were made in this
00:02:26
boiler room, and so the number one mistake we have is a
00:02:31
two-story building, studying each of the
00:02:33
floors is equal approximately 130
00:02:35
square meters, the first floor is heated
00:02:37
exclusively with heated floors and several
00:02:40
heated floor circuits on the second floor,
00:02:43
bathrooms in the hallway, a small area
00:02:45
under the window in just a year, we have floors in the
00:02:48
area of ​​140,150 square meters and for
00:02:51
this area we have installed 2 pumps for
00:02:54
mixing groups with installers those who
00:02:57
installed explained this decision
00:02:59
by the fact that one group may simply not be
00:03:01
enough,
00:03:02
but this is not so, we have a pump
00:03:05
installed 25 to 60 and one of this group
00:03:08
up to 100 kW would be even much
00:03:11
larger than there is a
00:03:13
way out of this situation in this building, we will
00:03:16
turn off the 1c mixers, one pump
00:03:19
group and or connect all the collectors
00:03:22
on one of them, as a result we have
00:03:25
one pump group,
00:03:28
problem number two is that it is planned to build a small one near the
00:03:32
building in the future,
00:03:34
both
00:03:36
should not be heated; a
00:03:39
heating main was laid in advance and
00:03:42
connected for this node it is not a
00:03:46
mixer, it is direct and this node
00:03:49
feeds 6 radiators that we
00:03:52
have on the second floor of the building,
00:03:54
in total there are only six radiators no longer a
00:03:56
radiator here, the result is that we are
00:03:58
connected to it, the future is sick and 6
00:04:00
radiators for one pump is also
00:04:03
incorrect because there is a separate
00:04:06
building that will be heated by this
00:04:08
boiler room, there must be a
00:04:10
separate unit for the needs of this building, it
00:04:14
can be controlled either by an
00:04:16
expansion module or by a room
00:04:19
thermostat up to 8, it is not even really known
00:04:21
what kind of
00:04:23
heating system will be in this future building and The
00:04:26
way out of this situation is to disconnect
00:04:28
the heating main from the upper radiators and
00:04:31
connect the pump to the freed-up
00:04:34
mixing unit, set
00:04:36
the mixer to the zero position and as
00:04:39
a result it will be like this, as
00:04:40
usual, the pump will fill our bathhouse
00:04:43
with coolant,
00:04:45
problem number three, a large number of
00:04:48
check valves at the inlet of the output of the
00:04:51
boiler and even for loading the boiler, here
00:04:54
they are absolutely not needed since the
00:04:56
check valve, let me remind you, exists
00:04:59
to prevent parasitic
00:05:01
flows and here they have nowhere to come from
00:05:03
since they are connected directly to the
00:05:05
separator by a ring; the separator
00:05:07
is precisely the areas with zero
00:05:09
resistance which itself in themselves,
00:05:11
they prevent any stray flow
00:05:13
that is possible, but the
00:05:16
ring will
00:05:19
spend about a quarter of its
00:05:21
power on overcoming these valves just to
00:05:23
overcome the resistance of these platons,
00:05:25
this only interferes with the operation of the boiler, we
00:05:28
will remove them from here and connect them
00:05:31
without these valves, we will have everything
00:05:34
work in the same way,
00:05:37
I’ll remove the camera to show here there
00:05:42
are
00:05:46
still some difficulties, look at the
00:05:52
bottom comb, we have 8 free
00:05:54
terminals,
00:05:57
four of them we use three for the kitchen,
00:06:00
one bathroom and 4 will remain
00:06:02
unclaimed, why so, I don’t know,
00:06:05
maybe there was a mistake in the calculations when they were
00:06:07
purchased, but the thing is that
00:06:09
we have the upper hectare of the child with just
00:06:11
4 circuits, we will connect these 4 circuits
00:06:15
here and as a result
00:06:19
we will not need the upper manifold at all, it will free up
00:06:22
space for us and remove unnecessary
00:06:26
fittings connecting the fitting in the connection
00:06:28
by the way here too there are a lot of them here, but you do
00:06:31
n’t need such a hodgepodge of
00:06:33
pipes, it could all be done much more
00:06:35
compactly and smoother than this here,
00:06:38
remember the game in plumbing where you need to
00:06:41
lay a pipe from one point to another, so
00:06:43
something similar here turns out, look
00:06:45
at us, the pipe makes how much of a change
00:06:47
directions one two three 4 5 six and you only
00:06:52
need one, or at most two,
00:06:54
to free up this area if
00:06:56
you wanted to unwind the contour of the heated
00:06:59
floor here, so we have everything ready,
00:07:02
just a frame on the video was changed, in
00:07:05
fact, quite a
00:07:07
lot of work was done and it needs
00:07:08
to be redone it’s always much more difficult
00:07:11
than doing it correctly from the beginning, as
00:07:13
a result of which we got it like I and the
00:07:17
fairy planned, we connected all the collectors of
00:07:20
Perry’s underfloor heating to one pump on the
00:07:22
mixing unit, now, even at
00:07:25
first speed, it copes
00:07:26
with its duties remarkably well, as I said,
00:07:30
it has potential for a much larger
00:07:32
area than in this house,
00:07:35
we disconnected the bathhouse from the radiator network of the
00:07:38
second floor, turned it off and Perry
00:07:41
connected it to the vacant
00:07:43
3-way node zero position and
00:07:46
thus we will work like a regular
00:07:49
pump,
00:07:50
now the bathhouse has gained independence in
00:07:52
control in the future it will be possible
00:07:54
connect to it any heating system
00:07:57
that will be needed, a
00:07:59
check valve, we removed everything instead of
00:08:03
them, we installed extension cords
00:08:05
here, they are not necessary, they are not added, just like the
00:08:07
havela, only he only has the load on the pump,
00:08:09
which is absolutely what
00:08:12
I need here, here is the upper manifold near the
00:08:17
heated floor, the upper manifold we
00:08:20
removed perry we connected the circuit to the
00:08:22
free positions in the bottom why it
00:08:25
was always installed, it remained
00:08:27
a mystery to the free space we
00:08:29
installed a
00:08:32
hot water supply distribution unit,
00:08:35
of course I’m not a fan of this approach, in
00:08:37
my opinion such houses should have two
00:08:39
taps, one cold and the other hot,
00:08:41
but since all the material had already been
00:08:43
purchased and was on site, we decided
00:08:46
to work out exactly this option and at the
00:08:49
insistence of the customer, now each
00:08:52
bathroom is also closed separately, in general
00:08:56
we installed the tank and hung it on the wall, the
00:08:59
previous installers did not want to do this
00:09:01
since the wall would not hold up, in
00:09:04
fact, there is no need to hang it on the wall, this
00:09:06
kind of metal structure removes the weight of the
00:09:08
side onto the ceiling with its tankers behind the
00:09:10
floor slab, it holds perfectly
00:09:13
here we have freed up space, a
00:09:15
central vacuum cleaner system will be installed
00:09:17
under the tank, a
00:09:20
water filtration system will be neatly placed, and
00:09:22
for this, additional pipes have now been removed,
00:09:26
what else can we add in the piping we now have
00:09:29
much more there is more free space, not that is, there is no
00:09:32
former this mess of pipes, we
00:09:34
used a diagonal connection of
00:09:36
the collector, this makes it much easier for us
00:09:40
to balance the collectors, that’s
00:09:42
probably all, this is the
00:09:44
result,
00:09:48
this is what it looks like,
00:09:50
and finally, I would like to add that
00:09:53
he is engaged in a viscous boiler room and
00:09:55
designing a heating system from
00:09:57
yours at home as a whole there should not be a
00:10:00
subjective approach like it seems to me
00:10:03
or is everyone doing it this way, there
00:10:05
are calculations for this, they unambiguously
00:10:08
give answers to almost all questions and
00:10:11
in the case of two nodes it was enough to
00:10:14
calculate the volume of the required
00:10:16
coolant for the floor of its resistance
00:10:19
and knowing which pump is installed here it’s
00:10:21
easy to calculate the volume of
00:10:23
coolant that can be
00:10:25
pumped and there is an answer to the question whether a
00:10:27
second group is needed here or not. It’s
00:10:31
also very surprising that those
00:10:33
installers who worked before us
00:10:36
introduced themselves to the customer as participants,
00:10:38
even a teacher at a
00:10:40
heating school, as they put it in
00:10:42
Minsk.
00:10:44
I understand that they teach those
00:10:47
who want this craft, but in general,
00:10:51
you can draw conclusions from this, we have all the
00:10:53
best, goodbye
