00:00:00.030 so now I have with me Josh gardener who 00:00:02.41900:00:02.429 works for wind Elson and Josh and I 00:00:04.37000:00:04.380 actually did it walk through here 00:00:06.07900:00:06.089 several months ago to evaluate the 00:00:07.94000:00:07.950 existing system so Josh why don't you 00:00:09.91900:00:09.929 come on in for a sec Taylor now Josh got 00:00:13.94000:00:13.950 a couple questions here while we're here 00:00:15.35000:00:15.360 yeah 00:00:15.91900:00:15.929 obviously you can see like just showed 00:00:18.68000:00:18.690 around some of the people the heating 00:00:20.57000:00:20.580 and hot water systems that are here 00:00:23.30000:00:23.310 right now and in our discussions the 00:00:27.56000:00:27.570 customer wanted to save cost because of 00:00:31.16000:00:31.170 right now as we saw before the existing 00:00:34.19000:00:34.200 hot water system and the existing 00:00:37.43000:00:37.440 furnace which is a steam boiler are just 00:00:40.70000:00:40.710 ineffective and costing a lot of money 00:00:42.68000:00:42.690 in these diseconomies so just go through 00:00:47.36000:00:47.370 if you don't mind just the benefits of 00:00:51.02000:00:51.030 what we're trying to supply these 00:00:52.31000:00:52.320 customers today well the system we have 00:00:55.18900:00:55.199 right here is a steam hot steam for 00:00:59.06000:00:59.070 steam system that is shimmy drafted it's 00:01:02.68900:01:02.699 running probably the mid 70s for 00:01:04.96900:01:04.979 efficiency right now right and the 00:01:06.56000:01:06.570 domestic hot water is coming off the 00:01:08.53900:01:08.549 lower section of the steam boiler so the 00:01:10.10000:01:10.110 hot water that produces the steam that 00:01:12.62000:01:12.630 hot water is going into the indirect 00:01:14.60000:01:14.610 water heater giving the domestic hot 00:01:15.89000:01:15.900 water now I have a question that's 00:01:18.95000:01:18.960 that's pretty common in most residential 00:01:21.10900:01:21.119 applications and actually most setups 00:01:22.82000:01:22.830 where the steam as well the boiler will 00:01:26.17900:01:26.189 run both yeah whether it's a hydraulic 00:01:28.13000:01:28.140 system or a steam system right they're 00:01:31.03900:01:31.049 very common to have the indirect hot 00:01:33.17000:01:33.180 water heater coming out that system in 00:01:34.96900:01:34.979 some applications it works and it makes 00:01:37.10000:01:37.110 sense right other applications it 00:01:38.92900:01:38.939 doesn't and this send in this 00:01:40.39900:01:40.409 application it really does not make 00:01:42.31900:01:42.329 sense and it's a big money waster 00:01:44.09000:01:44.100 especially in the shoulder seasons of 00:01:45.49900:01:45.509 the summer so what we're planning to do 00:01:48.17000:01:48.180 here is remove the whole domestic hot 00:01:50.71900:01:50.729 water system off the steam heating 00:01:54.80000:01:54.810 system right and separate it to a 00:01:58.17900:01:58.189 high-efficiency condensing 98% efficient 00:02:02.53900:02:02.549 system right so come in the you know 00:02:05.56900:02:05.579 shoulder the fall spring and summer 00:02:07.24900:02:07.259 seasons right we can turn the steam 00:02:09.85900:02:09.869 boiler off right until that fuel source 00:02:12.11000:02:12.120 and 00:02:12.80900:02:12.819 you have another system that's 00:02:13.67900:02:13.689 completely separate that's running 00:02:15.30000:02:15.310 domestic hot water and 98 percent 00:02:17.55000:02:17.560 efficiency okay so a couple things we 00:02:21.11900:02:21.129 decided to is we so that's domestic hot 00:02:23.94000:02:23.950 water is this water tank right here now 00:02:26.09900:02:26.109 some systems the boiler will actually 00:02:29.36900:02:29.379 heat the home and also heat the water in 00:02:32.55000:02:32.560 one unit but because of the size of this 00:02:35.09900:02:35.109 facility doesn't make sense 00:02:40.79000:02:40.800 so Josh can you just tell us about the 00:02:43.38000:02:43.390 new steam boiler that's right in front 00:02:45.51000:02:45.520 of us right here yeah this one here is a 00:02:48.15000:02:48.160 Barnum mega steam it is a five section 00:02:52.23000:02:52.240 boiler steam boiler right 00:02:54.45000:02:54.460 it's for oil and link doesn't come gas 00:02:57.54000:02:57.550 and it's going to replacing or 00:02:59.37000:02:59.380 inefficient steam boiler here our old 00:03:01.89000:03:01.900 one is running it probably the mid-70s 00:03:03.90000:03:03.910 for efficiency right um this one runs at 00:03:06.78000:03:06.790 about 86 percent efficient now for steam 00:03:09.75000:03:09.760 boilers yeah that's the highest you can 00:03:12.42000:03:12.430 possibly get what little steam boilers 00:03:15.33000:03:15.340 come across at 82 to 83 now if this was 00:03:19.62000:03:19.630 a most people well though there are a 00:03:22.29000:03:22.300 lot of homes that have steam steam 00:03:23.79000:03:23.800 radiators right now at their home so 00:03:25.71000:03:25.720 this might be although this is a larger 00:03:28.23000:03:28.240 unit for this large building but in 00:03:30.33000:03:30.340 their homes also if somebody had just a 00:03:32.85000:03:32.860 forced hot water system well what's the 00:03:35.07000:03:35.080 energy efficiency for one of those just 00:03:37.74000:03:37.750 look comparison with the steam with a 00:03:39.24000:03:39.250 forced hot water system I mean if you 00:03:41.10000:03:41.110 were stayed with a cast iron type boiler 00:03:42.93000:03:42.940 right you get something around 87 80 00:03:47.31000:03:47.320 percent efficient okay if you were to 00:03:49.32000:03:49.330 make the next step up and go with one of 00:03:51.42000:03:51.430 the modulating condensing one of the 00:03:53.58000:03:53.590 wall-hung boys you get it up to about 95 00:03:56.73000:03:56.740 to 97 percent okay so one question that 00:03:59.85000:03:59.860 people really would do ask is what does 00:04:01.65000:04:01.660 that mean what am i what is the 00:04:03.18000:04:03.190 percentage that we are getting is that 00:04:04.65000:04:04.660 the percentage of the oil or fuel that's 00:04:06.81000:04:06.820 used that's being actually actualized 00:04:10.26000:04:10.270 into heat 00:04:11.10000:04:11.110 how does that work well basically the 00:04:13.44000:04:13.450 efficiency set on what you're actually 00:04:15.99000:04:16.000 using right so you know one gallon of 00:04:19.11000:04:19.120 oil it's a one gallon of oil I mean 00:04:23.12000:04:23.130 probably about 15 percent of that let me 00:04:26.90900:04:26.919 go up the chimney right for 00:04:28.56000:04:28.570 high-efficiency mm-hmm 00:04:30.57000:04:30.580 so you know the 80 and we say eighty 00:04:33.33000:04:33.340 seven percent right that means 80 00:04:35.28000:04:35.290 percent of 87 percent of that gallon 00:04:37.50000:04:37.510 right we're actually using in this 00:04:39.57000:04:39.580 boiler okay the remainder is going up 00:04:41.97000:04:41.980 this chimney okay outside so now in this 00:04:45.21000:04:45.220 current boiler obviously with mid-70s 00:04:47.97000:04:47.980 so um people basically there's when you 00:04:51.18000:04:51.190 get your chimney excuse me when you get 00:04:52.86000:04:52.870 your boilers 00:04:54.53000:04:54.540 cleaned each year the boiler service 00:04:59.07000:04:59.080 will have a card they'll fill it out and 00:05:00.93000:05:00.940 they'll actually do a test on the 00:05:02.19000:05:02.200 efficiency of the unit yeah what it is 00:05:04.05000:05:04.060 is there's a combustion analysis machine 00:05:05.91000:05:05.920 that they put into the flue right and 00:05:08.70000:05:08.710 what happens is they run the boiler 00:05:10.29000:05:10.300 normally after they after they've done 00:05:12.03000:05:12.040 the cleaning now after they brush the 00:05:13.74000:05:13.750 boiler out and that combustion analyzer 00:05:16.44000:05:16.450 will tell them many different things 00:05:18.33000:05:18.340 what's going off the heating systems 00:05:19.65000:05:19.660 right and troubleshoot it and whatnot 00:05:20.82000:05:20.830 but it's also going to tell them the 00:05:22.44000:05:22.450 efficiency right and it's going to tell 00:05:24.15000:05:24.160 them the stack temperature they're 00:05:25.44000:05:25.450 losing 00:05:30.24000:05:30.250 don't film the stack temperature of what 00:05:32.44000:05:32.450 they're losing and and be able to help 00:05:37.27000:05:37.280 the the contractor adjust the efficiency 00:05:39.85000:05:39.860 to bring it up or down so if the 00:05:41.62000:05:41.630 customer in their house has a boiler 00:05:43.57000:05:43.580 that's working in the mid 70s they can 00:05:45.55000:05:45.560 they know that prop 30 percent 00:05:48.52000:05:48.530 potentially of the fuel usage is being 00:05:50.92000:05:50.930 actually burned up into the going up the 00:05:53.35000:05:53.360 chimney right and not being used into 00:05:54.97000:05:54.980 their heating of their home exactly it's 00:05:56.89000:05:56.900 just going through the boiler into the 00:05:58.57000:05:58.580 chimney right up and outside and they're 00:06:01.27000:06:01.280 losing that in so that's an easy way to 00:06:03.61000:06:03.620 somebody to calculate whether it's worth 00:06:05.47000:06:05.480 changing their boiler or not here's 00:06:07.00000:06:07.010 exactly you can look at your bills and 00:06:08.77000:06:08.780 kind of compute you know why you're 00:06:10.51000:06:10.520 actually spending how much is what your 00:06:12.40000:06:12.410 efficiency your heating system is 00:06:13.60000:06:13.610 correct and then you can actually look 00:06:14.98000:06:14.990 at a physical number of what you're 00:06:16.63000:06:16.640 actually losing up that chimney right 00:06:18.28000:06:18.290 and then you can look at that number you 00:06:20.38000:06:20.390 know and get quotes for various 00:06:21.94000:06:21.950 contractors and how much it cost to 00:06:23.68000:06:23.690 replace the heating system whether I 00:06:24.94000:06:24.950 open more high efficiency and you know 00:06:27.61000:06:27.620 whether or not that would make sense for 00:06:28.90000:06:28.910 you now in this application we've we're 00:06:31.69000:06:31.700 going to go with a unit a new unit 00:06:33.67000:06:33.680 that's 10 to 15% more efficient so right 00:06:37.48000:06:37.490 away there's a potential savings because 00:06:39.37000:06:39.380 we're utilizing more the fuel in heating 00:06:41.80000:06:41.810 the home or heating this home and then 00:06:43.81000:06:43.820 we've separated that the hot water 00:06:46.24000:06:46.250 system which runs off the oil onto a new 00:06:49.57000:06:49.580 propane or gas heating system correct 00:06:52.69000:06:52.700 that's correct and that unit we'll take 00:06:54.67000:06:54.680 a look at it runs at approximately 90 00:06:57.13000:06:57.140 was that 90% efficient right so you 00:06:59.74000:06:59.750 can't get antes I mean it's high as you 00:07:01.84000:07:01.850 go that's high as it goes yeah so why 00:07:03.37000:07:03.380 don't we maybe take a look over there 00:07:04.87000:07:04.880 see the guys from gal plumbing 00:07:06.34000:07:06.350 installing that system let's go
