00:00:05.060 how's it going on John the colon with 00:00:07.28000:00:07.290 McQuillan brothers Plumbing Heating and 00:00:08.75000:00:08.760 Air on the same pond Minnesota 00:00:10.45900:00:10.469 we're doing another video today we're 00:00:12.35000:00:12.360 going to be going through steam boilers 00:00:14.08900:00:14.099 so we're here at a homeowner's home in 00:00:16.60900:00:16.619 st. Paul who gave us kind enough to give 00:00:19.58000:00:19.590 us permission to use their steam boiler 00:00:21.17000:00:21.180 as an educational tool for all of our 00:00:24.01900:00:24.029 customers so the purpose of this video 00:00:26.81000:00:26.820 here really we want to just kind of go 00:00:28.97000:00:28.980 through steam boilers what all the 00:00:31.64000:00:31.650 components one of these controls do and 00:00:34.43000:00:34.440 then we'll touch on basic maintenance 00:00:36.56000:00:36.570 and what what you should expect is a 00:00:38.63000:00:38.640 homeowner with the steam system as far 00:00:40.43000:00:40.440 as as far as annual maintenance goes 00:00:42.65000:00:42.660 this bad boys so I'll start up here 00:00:45.44000:00:45.450 first thing we've got here this is our 00:00:47.24000:00:47.250 gauge this is just going to be telling 00:00:49.76000:00:49.770 you the pressure that the boiler is 00:00:51.31900:00:51.329 operating at when it's on up top here 00:00:54.83000:00:54.840 with these little pigtails here we've 00:00:56.95900:00:56.969 got our vapor stem and our pressure 00:00:59.02900:00:59.039 troll 00:00:59.56900:00:59.579 so our vapor staff here this is our 00:01:01.72900:01:01.739 primary set point for our pressure for 00:01:05.24000:01:05.250 the system the pressure troll is 00:01:07.53900:01:07.549 operating as a high limit so should 00:01:10.34000:01:10.350 should your boiler pressure get above 00:01:12.26000:01:12.270 the set point the pressure troll will 00:01:14.63000:01:14.640 shut the burner off so we don't cook up 00:01:17.50000:01:17.510 so now down lower here this this here 00:01:21.53000:01:21.540 this is the area that you're going to 00:01:23.03000:01:23.040 add chemical treatment to your system 00:01:24.77000:01:24.780 and take care of any surging or cleaning 00:01:26.74900:01:26.759 the boiler go right here we've got our 00:01:29.81000:01:29.820 low water cutoff 00:01:31.73000:01:31.740 this is a huge component of your boiler 00:01:34.24900:01:34.259 system what this is going to do is 00:01:36.23000:01:36.240 should your boiler system run dry it's 00:01:38.66000:01:38.670 going to turn the burners off so you 00:01:40.13000:01:40.140 don't have flames going on an empty 00:01:41.87000:01:41.880 boiler again this is this is one of your 00:01:45.53000:01:45.540 primary safety zone your boiler followed 00:01:48.77000:01:48.780 by that we've got the sight glass sight 00:01:50.92900:01:50.939 glasses the whole purpose of it is so 00:01:53.71900:01:53.729 that you can look at your boiler and see 00:01:55.52000:01:55.530 where your water level is so one thing 00:01:58.24900:01:58.259 to look for on a sight glass is when 00:01:59.96000:01:59.970 your boilers operating look for surging 00:02:02.81000:02:02.820 so if you notice that you're cyclists 00:02:04.70000:02:04.710 the water in it is bouncing up down up 00:02:06.92000:02:06.930 down up down quite a bit it's definitely 00:02:09.80000:02:09.810 time to call it 00:02:11.05000:02:11.060 when you're seeing major surging what's 00:02:12.97000:02:12.980 going on is you've got we've got layers 00:02:15.00900:02:15.019 of oil and debris on top of the water 00:02:17.58900:02:17.599 and it's preventing the water from 00:02:19.90000:02:19.910 turning into steam so it's actually 00:02:21.52000:02:21.530 holding the water back so definitely 00:02:23.38000:02:23.390 something to check out if you're 00:02:24.40000:02:24.410 noticing that if you're here in the st. 00:02:27.58000:02:27.590 Paul Minneapolis area and you've got a 00:02:29.71000:02:29.720 steam boiler and you noticing a lot of 00:02:31.21000:02:31.220 surging definitely give them a bulldozer 00:02:32.89000:02:32.900 call but we've been working on steamers 00:02:35.32000:02:35.330 since since 1883 so well over 130 years 00:02:39.46000:02:39.470 so we're very well dialed in on how they 00:02:42.40000:02:42.410 operate I would even go there saying 00:02:44.47000:02:44.480 we're one of the few contractors that 00:02:46.05900:02:46.069 still operate steam boilers in the state 00:02:48.33900:02:48.349 so the way the steam boiler works is 00:02:50.35000:02:50.360 it's going to boil water it's going to 00:02:52.05900:02:52.069 make steam the steam is going to go out 00:02:53.77000:02:53.780 travel to your radiators and then it's 00:02:56.47000:02:56.480 going to stop at your radiators via the 00:02:58.87000:02:58.880 steam trail so as that steam gives off 00:03:01.36000:03:01.370 heat it's going to condense into water 00:03:03.30000:03:03.310 the water is going to open the trap 00:03:05.72900:03:05.739 allowing the water to come back to the 00:03:07.90000:03:07.910 boiler and then when the steam it's the 00:03:09.91000:03:09.920 trap it impose it back down as far as 00:03:13.03000:03:13.040 maintenance goes on a steam boiler with 00:03:15.09900:03:15.109 quadlin brothers we highly recommend 00:03:16.15000:03:16.160 having a technician come out once a year 00:03:18.09900:03:18.109 most older homeowners do at the 00:03:20.62000:03:20.630 beginning of the heating season make 00:03:22.72000:03:22.730 sure the system is operating smoothly 00:03:24.37000:03:24.380 efficiently and safely as they go 00:03:26.08000:03:26.090 forward into the cold winter do it blow 00:03:29.47000:03:29.480 downs 00:03:30.06900:03:30.079 the whole point of this valve here is to 00:03:32.41000:03:32.420 blow the system down as you make steam 00:03:35.37900:03:35.389 with water all of the sediment is going 00:03:37.69000:03:37.700 to settle on the bottom of the boiler so 00:03:40.21000:03:40.220 blowing it down is critical as far as 00:03:42.00900:03:42.019 getting that sediment out so you 00:03:43.75000:03:43.760 actually see your boiler can operated at 00:03:46.09000:03:46.100 its peak efficiency so that's really the 00:03:49.12000:03:49.130 run down on steam if you have any 00:03:51.00900:03:51.019 questions or concerns with service and 00:03:53.25900:03:53.269 you're in st.
