how's it going on John the colon with
00:00:07.280 00:00:07.290 McQuillan brothers Plumbing Heating and
00:00:08.750 00:00:08.760 Air on the same pond Minnesota
00:00:10.459 00:00:10.469 we're doing another video today we're
00:00:12.350 00:00:12.360 going to be going through steam boilers
00:00:14.089 00:00:14.099 so we're here at a homeowner's home in
00:00:16.609 00:00:16.619 st. Paul who gave us kind enough to give
00:00:19.580 00:00:19.590 us permission to use their steam boiler
00:00:21.170 00:00:21.180 as an educational tool for all of our
00:00:24.019 00:00:24.029 customers so the purpose of this video
00:00:26.810 00:00:26.820 here really we want to just kind of go
00:00:28.970 00:00:28.980 through steam boilers what all the
00:00:31.640 00:00:31.650 components one of these controls do and
00:00:34.430 00:00:34.440 then we'll touch on basic maintenance
00:00:36.560 00:00:36.570 and what what you should expect is a
00:00:38.630 00:00:38.640 homeowner with the steam system as far
00:00:40.430 00:00:40.440 as as far as annual maintenance goes
00:00:42.650 00:00:42.660 this bad boys so I'll start up here
00:00:45.440 00:00:45.450 first thing we've got here this is our
00:00:47.240 00:00:47.250 gauge this is just going to be telling
00:00:49.760 00:00:49.770 you the pressure that the boiler is
00:00:51.319 00:00:51.329 operating at when it's on up top here
00:00:54.830 00:00:54.840 with these little pigtails here we've
00:00:56.959 00:00:56.969 got our vapor stem and our pressure
00:00:59.029 00:00:59.039 troll
00:00:59.569 00:00:59.579 so our vapor staff here this is our
00:01:01.729 00:01:01.739 primary set point for our pressure for
00:01:05.240 00:01:05.250 the system the pressure troll is
00:01:07.539 00:01:07.549 operating as a high limit so should
00:01:10.340 00:01:10.350 should your boiler pressure get above
00:01:12.260 00:01:12.270 the set point the pressure troll will
00:01:14.630 00:01:14.640 shut the burner off so we don't cook up
00:01:17.500 00:01:17.510 so now down lower here this this here
00:01:21.530 00:01:21.540 this is the area that you're going to
00:01:23.030 00:01:23.040 add chemical treatment to your system
00:01:24.770 00:01:24.780 and take care of any surging or cleaning
00:01:26.749 00:01:26.759 the boiler go right here we've got our
00:01:29.810 00:01:29.820 low water cutoff
00:01:31.730 00:01:31.740 this is a huge component of your boiler
00:01:34.249 00:01:34.259 system what this is going to do is
00:01:36.230 00:01:36.240 should your boiler system run dry it's
00:01:38.660 00:01:38.670 going to turn the burners off so you
00:01:40.130 00:01:40.140 don't have flames going on an empty
00:01:41.870 00:01:41.880 boiler again this is this is one of your
00:01:45.530 00:01:45.540 primary safety zone your boiler followed
00:01:48.770 00:01:48.780 by that we've got the sight glass sight
00:01:50.929 00:01:50.939 glasses the whole purpose of it is so
00:01:53.719 00:01:53.729 that you can look at your boiler and see
00:01:55.520 00:01:55.530 where your water level is so one thing
00:01:58.249 00:01:58.259 to look for on a sight glass is when
00:01:59.960 00:01:59.970 your boilers operating look for surging
00:02:02.810 00:02:02.820 so if you notice that you're cyclists
00:02:04.700 00:02:04.710 the water in it is bouncing up down up
00:02:06.920 00:02:06.930 down up down quite a bit it's definitely
00:02:09.800 00:02:09.810 time to call it
00:02:11.050 00:02:11.060 when you're seeing major surging what's
00:02:12.970 00:02:12.980 going on is you've got we've got layers
00:02:15.009 00:02:15.019 of oil and debris on top of the water
00:02:17.589 00:02:17.599 and it's preventing the water from
00:02:19.900 00:02:19.910 turning into steam so it's actually
00:02:21.520 00:02:21.530 holding the water back so definitely
00:02:23.380 00:02:23.390 something to check out if you're
00:02:24.400 00:02:24.410 noticing that if you're here in the st.
00:02:27.580 00:02:27.590 Paul Minneapolis area and you've got a
00:02:29.710 00:02:29.720 steam boiler and you noticing a lot of
00:02:31.210 00:02:31.220 surging definitely give them a bulldozer
00:02:32.890 00:02:32.900 call but we've been working on steamers
00:02:35.320 00:02:35.330 since since 1883 so well over 130 years
00:02:39.460 00:02:39.470 so we're very well dialed in on how they
00:02:42.400 00:02:42.410 operate I would even go there saying
00:02:44.470 00:02:44.480 we're one of the few contractors that
00:02:46.059 00:02:46.069 still operate steam boilers in the state
00:02:48.339 00:02:48.349 so the way the steam boiler works is
00:02:50.350 00:02:50.360 it's going to boil water it's going to
00:02:52.059 00:02:52.069 make steam the steam is going to go out
00:02:53.770 00:02:53.780 travel to your radiators and then it's
00:02:56.470 00:02:56.480 going to stop at your radiators via the
00:02:58.870 00:02:58.880 steam trail so as that steam gives off
00:03:01.360 00:03:01.370 heat it's going to condense into water
00:03:03.300 00:03:03.310 the water is going to open the trap
00:03:05.729 00:03:05.739 allowing the water to come back to the
00:03:07.900 00:03:07.910 boiler and then when the steam it's the
00:03:09.910 00:03:09.920 trap it impose it back down as far as
00:03:13.030 00:03:13.040 maintenance goes on a steam boiler with
00:03:15.099 00:03:15.109 quadlin brothers we highly recommend
00:03:16.150 00:03:16.160 having a technician come out once a year
00:03:18.099 00:03:18.109 most older homeowners do at the
00:03:20.620 00:03:20.630 beginning of the heating season make
00:03:22.720 00:03:22.730 sure the system is operating smoothly
00:03:24.370 00:03:24.380 efficiently and safely as they go
00:03:26.080 00:03:26.090 forward into the cold winter do it blow
00:03:29.470 00:03:29.480 downs
00:03:30.069 00:03:30.079 the whole point of this valve here is to
00:03:32.410 00:03:32.420 blow the system down as you make steam
00:03:35.379 00:03:35.389 with water all of the sediment is going
00:03:37.690 00:03:37.700 to settle on the bottom of the boiler so
00:03:40.210 00:03:40.220 blowing it down is critical as far as
00:03:42.009 00:03:42.019 getting that sediment out so you
00:03:43.750 00:03:43.760 actually see your boiler can operated at
00:03:46.090 00:03:46.100 its peak efficiency so that's really the
00:03:49.120 00:03:49.130 run down on steam if you have any
00:03:51.009 00:03:51.019 questions or concerns with service and
00:03:53.259 00:03:53.269 you're in st. Paul Minneapolis area
