00:00:09.700 you 00:00:15.34000:00:15.350 hey Jeff love here from alternative 00:00:17.69000:00:17.700 heating and supplies again we're going 00:00:19.46000:00:19.470 to be talking about how to install a 00:00:20.81000:00:20.820 plate exchanger on top of a domestic hot 00:00:22.73000:00:22.740 water tank this time and this is another 00:00:24.98000:00:24.990 big call that again a lot of questions 00:00:26.51000:00:26.520 about it but this is so simple it should 00:00:29.63000:00:29.640 be pretty quick to show you now once I 00:00:31.13000:00:31.140 give you a visual everybody it clicks 00:00:32.93000:00:32.940 and everybody gets it what I have here 00:00:35.03000:00:35.040 is I'm going to be using a 20 plate heat 00:00:37.10000:00:37.110 exchanger now a lot of people ask me how 00:00:40.01000:00:40.020 do you know what size play exchanger to 00:00:41.93000:00:41.940 install in your domestic hot water tank 00:00:43.43000:00:43.440 simple rule of thumb is two to three 00:00:46.01000:00:46.020 people in one house will determine a 10 00:00:48.68000:00:48.690 plate a 10 plate heat exchangers enough 00:00:50.66000:00:50.670 for 2 or 3 people when you get into a 00:00:53.00000:00:53.010 full size family anywhere from 4 or 5 6 00:00:55.22000:00:55.230 people in the house I immediately 00:00:56.51000:00:56.520 recommend the 20 plate it will have 00:00:58.46000:00:58.470 plenty of power it'll have a good 00:01:00.46000:01:00.470 regenerative nature to it so will heat 00:01:02.87000:01:02.880 up the domestic hot water a lot faster 00:01:04.46000:01:04.470 this is the cold water side so cold 00:01:07.58000:01:07.590 water coming in obviously the plate 00:01:10.58000:01:10.590 exchangers are installed I didn't want 00:01:11.87000:01:11.880 to show you how to screw everything 00:01:13.81900:01:13.829 together I'm sure you all could figure 00:01:14.96000:01:14.970 all that how to do it this is your hot 00:01:17.17900:01:17.189 water side so you're going to mount your 00:01:19.16000:01:19.170 your plate exchanger on the cold water 00:01:21.53000:01:21.540 side and I'll explain to you why it's 00:01:23.84000:01:23.850 actually quite simple I call it a 00:01:25.19000:01:25.200 thermal pressure siphon explained in 00:01:27.29000:01:27.300 detail in just a minute so all you're 00:01:29.12000:01:29.130 going to do is the water line will come 00:01:30.56000:01:30.570 in and you're going to just cut it 00:01:31.64000:01:31.650 you're going to mount it you're going to 00:01:32.81000:01:32.820 do a 90 here going into the plate 00:01:35.14900:01:35.159 exchanger and I always recommend unions 00:01:36.95000:01:36.960 now you've got to use a lead-free copper 00:01:42.23000:01:42.240 and also brass in this case of this 00:01:44.45000:01:44.460 application I carry brass lead-free 00:01:46.85000:01:46.860 brass so I use brass here to give you 00:01:48.59000:01:48.600 this example so you're going to put a 00:01:51.02000:01:51.030 union here and then you come down in 00:01:52.49000:01:52.500 through the plate changer and then again 00:01:54.32000:01:54.330 another lead-free Union and then back 00:01:56.45000:01:56.460 into the plate into the domestic hot 00:01:58.70000:01:58.710 water tank 00:01:59.50000:01:59.510 these plague exchangers are stainless 00:02:01.55000:02:01.560 steel the place changes that I sell are 00:02:04.16000:02:04.170 also 40% heavier than the plate 00:02:06.28900:02:06.299 exchangers else that are out there on 00:02:07.55000:02:07.560 the market the plate exchangers can be 00:02:08.83900:02:08.849 used for many different applications 00:02:09.91900:02:09.929 anything from cooling or heating and 00:02:13.03900:02:13.049 warming up diesel to exchanging heat 00:02:15.47000:02:15.480 between polyurethane and an ax fridge 00:02:18.19900:02:18.209 Hrant and everything else but the heat 00:02:20.08900:02:20.099 exchangers that I have made specifically 00:02:22.16000:02:22.170 for me is made for the wood boiler 00:02:24.55900:02:24.569 application so it's a much heavier grade 00:02:26.69000:02:26.700 of plate exchanger which hurts my 00:02:28.80000:02:28.810 efficiency a little bit but I'd rather 00:02:31.53000:02:31.540 have the longevity and the quality and 00:02:34.19900:02:34.209 then instead of having to replace of 00:02:35.61000:02:35.620 every four or five years is what it 00:02:37.29000:02:37.300 seems like the other ones that I've come 00:02:38.88000:02:38.890 across are the less expensive or the 00:02:40.55900:02:40.569 lighter ones that I've seen so I went 00:02:43.50000:02:43.510 with a heavier grade and they should 00:02:45.24000:02:45.250 last you the lifetime of the boiler if 00:02:46.86000:02:46.870 not longer so in this case the water 00:02:51.15000:02:51.160 flow is going to be coming in from the 00:02:52.58900:02:52.599 domestic hot water side this way into it 00:02:55.44000:02:55.450 so the flow of the wood boiler is going 00:02:58.14000:02:58.150 to go the opposite direction you're 00:03:00.87000:03:00.880 trying to create a cross flow difference 00:03:02.85000:03:02.860 okay you get more heat exchange that way 00:03:05.40000:03:05.410 so the boiler coming in identified with 00:03:08.03900:03:08.049 the red pipe it's going to come into the 00:03:09.75000:03:09.760 bottom up flow and then out and returned 00:03:12.75000:03:12.760 to the boiler or to your next heating 00:03:15.18000:03:15.190 system and what will happen here is the 00:03:18.66000:03:18.670 reason and how this works is a thermal 00:03:20.94000:03:20.950 pressure siphon so what happens here is 00:03:23.40000:03:23.410 this water coming in from the boiler is 00:03:24.96000:03:24.970 anywhere in the ballpark of 170 to 180 00:03:27.15000:03:27.160 degrees so it's heating up the water in 00:03:29.10000:03:29.110 this plate exchanger which is coming in 00:03:30.66000:03:30.670 roughly 55 degrees 00:03:32.33900:03:32.349 give or take a couple degrees depending 00:03:33.81000:03:33.820 on what zip code you're from so the 00:03:35.69900:03:35.709 water in here is getting hotter and 00:03:37.22900:03:37.239 hotter and hotter so it's building up 00:03:39.18000:03:39.190 pressure because when heat when water 00:03:41.49000:03:41.500 gets heated it expands and of course 00:03:46.05000:03:46.060 being in this pipe it's building 00:03:47.67000:03:47.680 pressure because this tank is also 00:03:49.71000:03:49.720 pressurized that's how it gets water to 00:03:51.69000:03:51.700 your tap so the water in here is getting 00:03:54.09000:03:54.100 hotter and hotter in the pressures 00:03:55.25900:03:55.269 building the tank the water in there is 00:03:59.00900:03:59.019 naturally cooling that's why it's 00:04:00.24000:04:00.250 covered with so much insulation so the 00:04:02.12900:04:02.139 pressure and this is dropping so the 00:04:04.31900:04:04.329 pressure between this and the water 00:04:06.00000:04:06.010 jacket in here and the water in here the 00:04:08.64000:04:08.650 two pressures are going to neutralize 00:04:10.14000:04:10.150 and when you have that natural 00:04:12.21000:04:12.220 neutralization the water temperature 00:04:14.34000:04:14.350 equals out so that's how the thermal 00:04:16.83000:04:16.840 pressure siphon works if that makes 00:04:18.39000:04:18.400 sense so once again the water in here 00:04:20.46000:04:20.470 heats up builds up pressure the water 00:04:22.44000:04:22.450 here is slowly but surely cooling and 00:04:24.39000:04:24.400 those two will neutralize at the same 00:04:27.09000:04:27.100 psi or pressure which is about the same 00:04:29.58000:04:29.590 temperature you're going to get this 00:04:31.05000:04:31.060 tank at about 130 degrees with again no 00:04:34.20000:04:34.210 pump no circulation it's going to use 00:04:36.36000:04:36.370 the thermal pressure siphon to do it if 00:04:37.89000:04:37.900 it's installed correctly the most 00:04:39.83900:04:39.849 important thing is that you've got to 00:04:41.46000:04:41.470 make sure you 00:04:42.15000:04:42.160 using a copper a good grade copper on 00:04:44.16000:04:44.170 the on the domestic hot water side or 00:04:46.17000:04:46.180 lead-free brass you've got to use these 00:04:49.05000:04:49.060 things because this is water that's now 00:04:50.64000:04:50.650 going to be entering your domestic hot 00:04:52.32000:04:52.330 water system possibly drinking it and 00:04:53.82000:04:53.830 you're going to be bathing in it so make 00:04:55.32000:04:55.330 sure you get good quality brass we can 00:04:56.88000:04:56.890 we have brass and we sell it another 00:04:59.46000:04:59.470 common question that we get a lot is do 00:05:01.89000:05:01.900 you heat the domestic hot water first or 00:05:03.96000:05:03.970 do you heat the boiler first or the hot 00:05:06.06000:05:06.070 air furnace first the answer is you're 00:05:08.67000:05:08.680 always going to go to the domestic hot 00:05:10.08000:05:10.090 water first the reason why is if you're 00:05:12.60000:05:12.610 taking a shower and you get a couple 00:05:13.83000:05:13.840 degree difference in your shower you're 00:05:15.48000:05:15.490 going to know immediately if your wife 00:05:17.25000:05:17.260 gets it you're going to hear about it so 00:05:18.87000:05:18.880 make sure you go to the domestic hot 00:05:21.12000:05:21.130 water first when you go to your boiler 00:05:24.21000:05:24.220 after this if the temperature house is 00:05:26.22000:05:26.230 off a degree you won't even notice in 00:05:28.26000:05:28.270 the hot air system but once you're done 00:05:29.97000:05:29.980 with the shower and you're taking a lot 00:05:31.32000:05:31.330 of heat from the the loop from the wood 00:05:33.63000:05:33.640 boiler or it any contradiction alcoa 00:05:36.54000:05:36.550 boiler any other boiler system it will 00:05:39.75000:05:39.760 catch up and get the hot air system so 00:05:42.09000:05:42.100 I'll back up here and go one more time 00:05:44.16000:05:44.170 so the water coming in from the wood 00:05:45.57000:05:45.580 boiler coal furnace boiler any kind of 00:05:48.12000:05:48.130 boiler system you have with alternative 00:05:49.95000:05:49.960 energy or any boiler you're going to 00:05:52.74000:05:52.750 come in you're going to hit the domestic 00:05:54.00000:05:54.010 hot water first then from there you're 00:05:56.64000:05:56.650 going to come out and you're going to go 00:05:57.75000:05:57.760 to your boiler your hot air furnace or 00:06:00.18000:06:00.190 any other conventional heating system 00:06:01.83000:06:01.840 you have and then back to your wood coal 00:06:04.74000:06:04.750 or alternative energy boiler and that's 00:06:07.74000:06:07.750 really all you have to do that's how 00:06:09.36000:06:09.370 simple these things are to install and 00:06:11.10000:06:11.110 the nice thing is this when they're when 00:06:13.32000:06:13.330 they're not being used the water will 00:06:15.12000:06:15.130 just throw flow right through your plate 00:06:18.57000:06:18.580 exchanger into your domestic hot water 00:06:19.86000:06:19.870 tank and the tank will work as it was 00:06:22.65000:06:22.660 before it was installed there's nothing 00:06:24.84000:06:24.850 you need to do the plate exchanger will 00:06:26.82000:06:26.830 actually heat up the tank a little bit 00:06:28.65000:06:28.660 warmer than the tank is set for so what 00:06:31.89000:06:31.900 will happen is the tank will never 00:06:33.36000:06:33.370 really turn on its coil system only will 00:06:35.76000:06:35.770 turn on its coil system once you stop 00:06:37.44000:06:37.450 using your boiler and that applies if 00:06:40.20000:06:40.210 your boiler is at about 180 degrees if 00:06:43.20000:06:43.210 you're running a boil a little cooler 00:06:44.28000:06:44.290 and that the coils inside this might be 00:06:46.50000:06:46.510 turned on okay but that's all there is 00:06:48.93000:06:48.940 to it if you have any questions comments 00:06:51.75000:06:51.760 if you liked the video give me a thumbs 00:06:53.04000:06:53.050 up at the bottom if you have any 00:06:54.51000:06:54.520 suggestions or areas 00:06:55.83000:06:55.840 you don't understand you would like to 00:06:56.93900:06:56.949 see a video on please make a comment 00:06:58.83000:06:58.840 below let us know if there's anything 00:07:00.15000:07:00.160 else we could do to help you and that's 00:07:02.07000:07:02.080 what we're here for 00:07:02.97000:07:02.980 check us out alternative heating and 00:07:04.68000:07:04.690 supplies thank you and have a great day
